MS8005
——————————————————————————————————————————————————————————
The
MS8005 is a general-purpose 1T 8051 Core MCU. Under the same system clock, it
runs faster and has better performance than the traditional 8051. The
instruction code is fully compatible with the traditional 8051. It retains the
main features of the standard 8051, including 256-byte RAM and 2 16-bit
locators. The chip also integrates 2K bytes of external expansion RAM and 32K
OTP ROM, and can realize in-application programming (IAP) functions. The chip
integrates 12-bit ADC with digital comparison function, two serial ports with
its own baud rate generator, 3 channels of 16-bit resolution PWM and other rich
peripheral resources. MS8005 integrates RC oscillators (RC16M and RC40K),
watchdog timer, power-on reset and low-voltage reset functions, thus
eliminating the need for external crystal oscillators and peripheral circuits
such as reset. MS8005 is a high-performance, low-cost, and highly reliable MCU.
