Introduction to EMMC Circuits EMMC (Embedded Multi Media Card) is a standard specification for embedded storage primarily aimed at products like mobile phones or tablets, established by the MMC Association. EMMC integrates a controller within the package, providing a standard interface and managing flash memory.The schematic for the 8-bit data signal is shown in Figure … Read more
Today we analyze a classic microcontroller power supply circuit. The circuit schematic is shown below: ▲ Simplified Switch Circuit Before powering the circuit, the switch “TEST” is open, and the microcontroller is not powered through VCC. At this time, the base of T1 is grounded through R9 (100k), and is in the cutoff state. The … Read more
With the development of the times, people have gradually started to design various types of chips, one of which is the popular low-power chip design. These chips not only help extend the battery life of devices but also reduce the likelihood of overheating and improve system stability. If you want to design low-power chips, then … Read more

Hello everyone, I am Tao Ge. Having been in contact with computers for many years, I often feel a sense of confusion. Today, let’s work together to build a computer to deepen our understanding and experience. It must be stated that computers can be complex or simple, but their structures and principles are fundamentally similar. … Read more
315M Transmission Circuit Principles In a static state, 12V provides voltage to the collector of Q2 through L1, R1, and the base-emitter of Q1. When data arrives, Q2 turns on, causing the emitter of Q1 to be at 0 potential, which means Q1 is initially off. When the emitter of Q1 is at 0 potential, … Read more
The DAC0832 is an 8-bit resolution D/A converter integrated chip. It is fully compatible with microprocessors. This D/A chip is widely used in microcontroller application systems due to its low cost, simple interface, and easy conversion control. The D/A converter consists of an 8-bit input latch, an 8-bit DAC register, an 8-bit D/A conversion circuit, … Read more
