When it comes to STC single-chip microcomputers, some people will say that STC can also be regarded as the mainstream. We base it on the fact that it is a relatively good single-chip microcomputer in China. STC MCU is a single-clock/machine-cycle MCU produced by Hongjing. To put it bluntly, STC MCU is a combination of 51 and AVR. Some people say that AVR is a substitute for 51. However, AVR MCU has a lot of in-position control and C language writing. The difference. The STC MCU Qiaqia combines the advantages of 51 and AVR. Although the function is not as powerful as AVR, the functions that can be found in AVR are basically available on STC. At the same time, STC MCU has a 51 core, which is based on 51 MCU. The engineers provided great convenience, saving the time of learning AVR, and at the same time not losing the various functions of AVR.
STC single-chip microcomputer is a new generation of 8051 single-chip microcomputer 51 with high speed, low power consumption and super anti-interference. The instruction code is fully compatible with the traditional 8051, but the speed is 8-12 times faster. The internal integrated MAX810 dedicated reset circuit. 4-channel PWM 8-channel high-speed 10-bit A, D conversion, aiming at motor supplier control, strong interference occasions, becoming a new series of single-chip microcomputers after 51 single-chip microcomputers.
characteristic1. Download the burning program and use the serial port to be convenient and easy to use. It has a lot of learning materials and videos. The most famous one belongs to the video of Changhui Instrument Network. Many friends who are interested in microcontrollers use this video to get started. Yes, it also has wide voltage: 5.5～3.8V, 2.4～3.8V, low power consumption design: idle mode, power-down mode (can be awakened by external interrupt).
2. STC single-chip microcomputer has in-application programming, it is more convenient to debug; with 10-bit AD, internal EEPROM, can work under 1T/machine cycle, the speed is 8-12 times of the traditional 51 single-chip microcomputer, and the price is relatively cheap.
3. 4-channel capture/compare unit. The STC12C2052AD series is 2-channel, which can also be used to realize 4 timers or 4 external interrupts, 2 hardware 16-bit timers, compatible with ordinary 8051 timers. 4-channel PCA can also implement 4 more timers, with hardware watchdog, high-speed SPI communication port, full-duplex asynchronous serial port, compatible with ordinary 8051 serial ports, and also has an advanced instruction set structure, compatible with ordinary 8051 instructions set.
DisadvantageAlthough the functions of STC single-chip microcomputer are not as powerful as AVR and STM32, and the price is not as cheap as 51 and ST32, these are not important. The important thing is that this is a relatively outstanding single-chip single-chip made in China.
