1.5 The Conflict Between Dynamic Power and Static Power Over the past 15 years, with the development of semiconductor technology, Vdd has decreased from 5V to 3.3V, and from 2.5V to 1.2V. The ITRS roadmap predicts that high-performance devices will use 1.0V in 2008 and 2009, while low-power devices will use 0.8V. The issue with … Read more
What are Always-On Logic Cells? Some logic needs to remain active during shutdown, such as Power Switch Cells, Retention Register Cells, and Isolation Cells. These are referred to as Always-On Logic Cells. They can maintain a constant ‘on’ state regardless of whether the voltage area is powered down. Always-On Logic Cell Where are they used? … Read more
In power-off modules, it may be required for the register to latch data before power-off or to restore latched data after power-on, which necessitates a special unit known as the Retention Register. The retention register consists of two sets of registers: the Main Register and the shadow register, where the shadow register is powered by … Read more

The Development Status and Advantages of Domestic FPGAs In recent years, the development of domestic FPGAs has been rapid, with a total of 22 FPGA manufacturers in China (19 excluding those for special purposes). Major companies include Unisoc, Anlogic, and Fudan Microelectronics. In terms of market share, the total revenue of major domestic FPGA design … Read more
Concept of Low Power In the design of embedded systems, low power design is a challenge that many designers must face. This is because embedded systems are widely used in portable and mobile products, which often do not have a constant power supply and rely on batteries for power. Therefore, designers consider every detail to … Read more
In the rapid development of the smart home field, low power design has become a core challenge for PCB design engineers. Smart home devices often require long standby times or rely on battery power, making power consumption requirements extremely stringent. This article will delve into low power design strategies for PCBs in smart home products, … Read more
Figure 3 PCB Wiring 4) Circuit Related Explanation As shown in Figure 1, R56 and R57 are the pull-up resistors on the I2C bus. The interrupt output and clock output of the PCF8563 are both open-drain outputs, so external pull-up resistors are also needed, such as R58 and R59 in Figure 1. If these two … Read more
The northwest wind is howling, and the annual heating season has arrived. Heating pipelines are so important during the winter in the north. The design of the pipelines is aimed at maximizing effective thermal energy under determined energy conditions. Low power design aims to meet functional requirements with minimal power consumption. The low power design … Read more
