High Integration Nature of Microcontroller

on 26/06/2023

Automotive engine control systems, implantable medical devices, remote controls, office equipment, appliances, power tools, toys, and other embedded systems are just a few examples of the automatically controlled goods and gadgets that use microcontrollers. Microcontrollers make it affordable to digitally control even more devices and processes since they are smaller and less expensive than designs that require individual microprocessors, memories, and input/output devices. In order to control non-digital electronic equipment, mixed signal microcontrollers are frequently used. Microcontrollers are a popular and affordable method of data collection, sensing, and controlling the physical world as edge devices in the context of the internet of things. A system on a chip is similar to a microcontroller in modern parlance, but it is less complex. However, a system on a chip typically combines cutting-edge peripherals like a graphics processing unit (GPU) and a Wi-Fi interface controller as its internal microcontroller unit circuits. A system of the chip may connect external microcontroller chips as motherboard components.
At this time, the majority of microcontrollers had concurrent variations. One contained an EPROM program memory that could be wiped by ultraviolet radiation thanks to a transparent quartz glass in the package’s lid. For prototyping, these erasable chips were frequently employed. The other version was either a mask-programmed ROM or a PROM variant which was only programmable once. For the latter, the abbreviation OTP, which stands for “one-time programmable,” was occasionally used. The PROM was typically the same type as the EPROM in an OTP microcontroller, but the chip packaging lacked a quartz window, making it impossible to expose the EPROM to UV light, which prevented it from being erased.
Because RAM and non-volatile memory are integrated on the same chip as the CPU in microcontrollers, they may not incorporate an external address or data bus. The semiconductor can be housed in much smaller, less expensive packaging by using fewer pins. It is more expensive to integrate the memory and other peripherals onto a single chip and test them together, but doing so frequently lowers the net cost of the embedded system as a whole. Even though the price of a CPU with integrated peripherals may be slightly higher than the price of a CPU with external peripherals, having fewer chips usually enables a smaller, less expensive circuit board, reduces the labor needed to assemble and test the circuit board, and also tends to lower the defect rate for the finished assembly. Due to this integration, fewer chips, less wiring, and less circuit board space are required to create identical systems than if separate chips were used. Additionally, each pin on devices with a low pin count, in particular, may connect to a number of internal peripherals, with the pin function being determined by software. As opposed to if pins had specific functions, this enables a part to be used in a larger range of applications. Since their invention in the 1970s, microcontrollers have proven to be extremely popular in embedded systems.
Some microcontrollers employ the Harvard design, which separates the memory buses for instructions and data to enable parallel accesses. When a Harvard architecture is employed, the bit size of the processor’s instruction words may differ from the size of internal memory and registers; an example would be 12-bit instructions used with 8-bit data registers.
It can be challenging to choose which peripheral to integrate. The operating frequencies and system design flexibility of microcontroller vendors are frequently exchanged for customer-driven time-to-market demands and overall lower system costs. Manufacturers must strike a compromise between the need to reduce chip size and the addition of new functionality.

‘Jubilee Corporation is a wonderful partner for its understanding of technology.’
Cheaper cost is nothing but a loss of time and resources, believes Julien

on 26/06/2023

T hough Jubilee Corporation is undoubtedly a big name in the engineering world in Pakistan, the company’s understanding of modern technologies and engineering surely transmits signals to its international partners—Lovato Electric—makes it a distinct engineering concern in Pakistan. The level of satisfaction comes from Lovato through its representative for Asia Pacific region Julien Mermillon who talked to ER during Multitopic Sympoisum 2023 hosted by IEEEP in Karachi. Here is his interview for our readers.
How is Lovato’s relationship with Jubilee Corporation?
It’s a great pleasure to work with Jubilee Corporation. They are very competent people with high technical skills. At Lovato, we sell quite complex engineering solutions, mainly focusing on energy management, metering, control, and protection equipment. Today’s topic was dynamic power factor correction, which is part of power quality solutions. But mainly, we are focusing on metering equipment to understand power quality and the energy consumption. This is about how the energy is spent and if the energy supplied to a facility has proper power quality to avoid any issues. Jubilee Corporation is providing a complete mix of solutions by Lovato, including what we discussed in the Symposium. This solution provides great efficiency at a reasonable cost suitable for the facilities of Pakistan.
The people are conscious of the cost here despite the importance of technology. How is it possible to offer efficient systems at lower costs?
The matter of cost is always, like we say, a balance between CapEx and OpEx. You can invest in technology with cheap products and solutions, which may last only two years. It means you have lost your valuable time and money. A quality product can last for 15 years, which is generally what Lovato is offering. We use the best quality parts in our products. Let’s assume that the product is a box, and inside this box are electronics. Our electronics are made up of premium quality parts, which ensure long product life. It may be higher in cost initially, but over time, it is much cheaper than replacing a low-quality product three or four times in the same period. Lovato Electric is a main player in this category. We are a family-owned business, which means that the company is reinvesting its money to improve the product, not to please shareholders. We are making the best product at the best price, which means that we are expensive than low-quality products available in the market. Our customer is satisfied with the quality of our products.
Many people in the engineering sector believe the Chinese are a big challenge. Are they a challenge for your company too?
They are a challenge for the entire world, especially from the business point of view. Luckily, they target different market segments. Usually, they bring some very cheap solutions at the cost of low durability and reliability. Maybe you don’t see it here, but they also bring some very advanced solutions, which came to be at the same price as us. The main difference between Chinese and western or Japanese, or Korean companies is that we cannot afford to have low-cost and low-quality products due to the high cost of labor. If you install some low-cost equipment and you need to replace it after a few months, that will cost you a huge labor cost. This will also disturb the production process of the facility and reduce operational efficiency. So, in the end, it is a different market segment. Some people may want to try it, but others would not go for it.
You are also looking after the Asia Pacific region for Lovato. What is the landscape there in terms of metering and such solutions?
I would say, as compared to Lovato’s historical market, there are quite massive developments that involve huge numbers of meters to monitor energy consumption accurately. We have sold one of the biggest metering systems. It’s a competitive and challenging market, but I must say it is also a land of opportunity. Our partners, like Jubilee Corporation, are doing a great job representing Lovato products in their respective market.
While working with Jubilee Corporation, has Lovato had any thought to engage in any joint venture to manufacture products and provide systems in Pakistan?
Lovato is a family-owned business, and we don’t have many factories around the world. We have three manufacturing facilities in Italy. We are a medium size company, and we are focusing on staying efficient. We have no factory outside Europe. Time will tell us if we move on to the stage where we start manufacturing somewhere else outside Europe. I believe Pakistan could be a very high potential market for us. I am always pleased with the Jubilee Corporation team because they are probably the most technical people and well-accustomed to Lovato products. When we have some training sessions to check how much knowledge is assimilated by our partners, we are pleased to see that they are at the top of the list. By Manzoor Shaikh

Leading exploration, production companies move to green energy

on 26/06/2023

Six Pakistani oil, and gas companies sign MoU for joint ventures; 15% of global energy-related greenhouse gas emissions come from oil and gas exploration
Leading oil and gas exploration companies in Pakistan have joined hands to
explore and pursue green hydrogen prospects, says the Petroleum Division of Pakistan’s Ministry of Energy.
These exploration and production companies include Oil & Gas Development Company Limited, Pak-Arab Refinery Limited, Pakistan Petroleum Limited, Mari Petroleum Company Limited, and Government Holdings (Private) Limited.
It merits mentioning that oil and gas are often painted as the dirtiest sector within the energy industry, but major companies around the world have begun to invest in renewable technologies in a bid to clean up the economy.
Of the six “super-majors” – BP, Shell, Chevron, Total, Eni, and Exxon – many of them have pumped billions into clean energy projects, although question marks remain over whether they are doing enough.
Despite the growth in renewables, “big oil” only spent 1% of its combined budget on green energy schemes in 2018.
The Petroleum Division says these companies in Pakistan have signed a memorandum of understanding (MoU) for joint ventures in the future.
The MoU will be initially effective for two years from the date of signing and it will engage consultants and advisors to explore the opportunities.
Under the MoU, the companies will also establish a joint fund to raise equity for joint ventures and green energy initiatives, said the statement.
Additional Secretary of the Petroleum Division Muhammad Mahmood, who witnessed the event, said that the collaboration could drive the energy transition towards a more sustainable future, leveraging each company’s expertise and resources.
“This collaboration is a significant step towards building a more sustainable future for Pakistan and beyond,” added the official.
On the occasion, Managing Director of the Oil & Gas Development Company Limited Ahmed Hayat Lak said, “we are confident that by leveraging our collective expertise and resources, we can accelerate the energy transition and create a greener, cleaner, and more prosperous future.”
The IEA’s Oil and Gas Industry in Energy Transitions report says while some oil and gas companies have taken steps to support efforts to combat climate change, the industry as a whole could play a much more significant role through its engineering capabilities, financial resources, and project-management expertise.
“No energy company will be unaffected by clean energy transitions,” said Dr. Fatih Birol. “Every part of the industry needs to consider how to respond. Doing nothing is simply not an option.”
The landscape of the oil and gas industry is diverse, meaning there is no single strategic response but a variety of approaches depending on each company’s circumstances.
“The first immediate task for all parts of the industry is reducing the environmental footprint of their own operations,” Dr. Birol said. “As of today, around 15% of global energy-related greenhouse gas emissions come from the process of getting oil and gas out of the ground and to consumers. A large part of these emissions can be brought down relatively quickly and easily.”
Reducing methane leaks into the atmosphere is the single most important and cost-effective way for the industry to bring down these emissions. But there are ample other opportunities to lower the emissions intensity of delivered oil and gas by eliminating routine flaring and integrating renewables and low-carbon electricity into new upstream and LNG developments.
“Also, with their extensive know-how and deep pockets, oil and gas companies can play a crucial role in accelerating deployment of key renewable options such as offshore wind, while also enabling some key capital-intensive clean energy technologies – such as carbon capture, utilisation, storage, and hydrogen – to reach maturity,” Dr. Birol added. “Without the industry’s input, these technologies may simply not achieve the scale needed for them to move the dial on emissions.”
Some oil and gas companies are diversifying their energy operations to include renewables and other low-carbon technologies. However, average investment by oil and gas companies in non-core areas has so far been limited to around 1% of total capital spending, with the largest outlays going to solar PV and wind. Some oil and gas companies have also diversified by acquiring existing non-core businesses – for example in electricity distribution, electric-vehicle charging, and batteries – while stepping up research and development activity. But overall, there are few signs of the large-scale change in capital allocation needed to put the world on a more sustainable path.
An essential task is to step up investment in fuels – such as hydrogen, biomethane, and advanced biofuels – that can deliver the energy system benefits of oil and gas without net carbon emissions. Within 10 years, these low-carbon fuels would need to account for around 15% of overall investment in fuel supply if the world is to get on course to tackle climate change. In the absence of low-carbon fuels, transitions become much harder and more expensive.
