Introduction to Common Microcontroller Chips STC Microcontroller The microcontrollers from STC are primarily based on the 8051 core, representing a new generation of enhanced microcontrollers. The instruction set is fully compatible with traditional 8051, offering speeds 8 to 12 times faster, equipped with ADC, 4-channel PWM, dual serial ports, a unique global ID, good encryption, and strong anti-interference capabilities. PIC Microcontroller: This product from MICROCHIP is characterized by its small size, low power consumption, simplified instruction set, good anti-interference, high reliability, strong analog interfaces, and good code confidentiality, with most chips having compatible FLASH program memory chips. EMC Microcontroller: This product from Etron Technology is largely compatible with PIC’s 8-bit microcontrollers, offering more resources compared to PIC’s compatible products, at a lower price, with many series to choose from, though it has poor anti-interference. ATMEL Microcontroller (51 Microcontroller): ATMEL’s 8-bit microcontrollers include the AT89 and AT90 series. The AT89 series is an 8-bit Flash microcontroller compatible with 8051 series microcontrollers, operating in static clock mode; the AT90 series microcontroller features an enhanced RISC architecture, fully static operation, and an internally programmable Flash, also known as AVR microcontroller. PHILIPS 51PLC Series Microcontroller (51 Microcontroller): PHILIPS’s microcontroller is based on the 80C51 core, embedding power loss detection, analog functions, and internal RC oscillators, making the 51LPC suitable for high integration, low-cost, and low-power application designs to meet various performance requirements. HOLTEK Microcontroller: This microcontroller from Holtek Semiconductor in Taiwan is inexpensive, with a wide variety, but has poor anti-interference, suitable for consumer products. TI Microcontroller (51 Microcontroller): Texas Instruments offers the TMS370 and MSP430 series of general-purpose microcontrollers. The TMS370 series is an 8-bit CMOS microcontroller with multiple storage modes and peripheral interface modes, suitable for complex real-time control scenarios; the MSP430 series is a low-power, highly integrated 16-bit microcontroller, especially suitable for low-power applications. Sonix Microcontroller (SONIX): This microcontroller from Sonix Technology in Taiwan is mostly 8-bit, with some compatible with PIC 8-bit microcontrollers, priced affordably, offering various options for system clock division, with PWM, ADC, internal oscillation, and internal noise filtering. Its drawbacks include small RAM space, though it has good anti-interference.
