51 MCU Development Board STC89C52
Description:
This experiment board is used for the STC production company 89C52 MCU. SCM is high quality at low cost, it is fully compatible with AT89S51 MCU of ATMEL company.
In addition to its many characteristics, such as: unable to decrypt, low power, high speed, high reliability, strong antistatic and strong interference and so on, STC company’s MCU internal resources are more rich than ATMEL company‘s SCM. It has 1280 bytes of SRAM, 8-64K bytes internal program memory, 2-8K bytes ISP boot code, except for P0-P3 port , it also has P4 port (PLCC package), chip has 8 road 8 AD (AD Series), chip also has EEPROM, watchdog, dual data pointers etc
51 MCU development board is like a variety of 51 SCM experimental boards, programming for assembly language or C language. When using STC MCU, directly to use product suite with serial line development board and computer serial port, and download programmer according to the STC single-chip tutorial download operation, the download speed faster than other download tools.
