A brief introduction of several commonly used single-chip microcontrollers in China:

PIC Microcontroller:

It's a product from MICROCHIP. It has small size, low power consumption, reduced instruction set, good anti-interference capability, high reliability, strong analog interface, and good code protection. Most chips have compatible FLASH program memory.

EMC Microcontroller:

Produced by Yilong Semiconductor in Taiwan. Many models are compatible with PIC 8-bit MCUs. It offers more resources than PIC at a lower cost, but it has weaker anti-interference performance.

ATMEL MCU (51 MCU):

ATMEL’s 8-bit MCU includes AT89 and AT90 series. AT89 is Flash-based and compatible with 8051. AT90 is RISC-based with internal programming capabilities, also known as AVR.

PHILIPS 51 PLC Series MCU (51 MCU):

Based on the 80C51 core, it includes power-down detection, analog functions, and on-chip RC oscillator. Suitable for high-integration, low-cost, and low-power applications.

HOLTEK Microcontroller:

A Taiwanese company's affordable and diverse range of MCUs, but with poor anti-interference, suitable for consumer electronics.

Texas Instruments (TI) MCU (51 Single Chip):

Offers TMS370 and MSP430 series. TMS370 is 8-bit CMOS MCU for real-time control. MSP430 is ultra-low-power 16-bit MCU ideal for low-power applications.
