2. General Description
The SH88F2051A/4051A is a high performance 8051 compatible micro-controller, regard to its build-in Pipe-line instruction
fetch structure, that helps the SH88F2051A/4051A can perform more fast operation speed and higher calculation performance,
if compare SH88F2051A/4051A with standard 8051 at same clock speed.
The SH88F2051A/4051A retains most features of the standard 2051. These features include internal 256 bytes RAM, UART
and Int0-2.In addition, the SH88F2051A/4051A provides external 256 bytes RAM, It also contains 4K/8K bytes Flash memory
block both for program and data. Also the ADC and PWM timer functions are incorporated in SH88F2051A/4051A.
For high reliability and low cost issues, the SH88F2051A/4051A builds in Watchdog Timer, Low Voltage Reset function. And
SH88F2051A/4051A also supports two power saving modes to reduce power consumption.
