2. General Description

The SH79F082 is a high performance 8051 compatible micro-controller, regard to its build-in Pipe-line instruction fetch

structure, that helps the SH79F082 can perform more fast operation speed and higher calculation performance, if compare

SH79F082 with standard 8051 at same clock speed.

The SH79F082 retains most features of the standard 8051. These features include internal 256 bytes RAM and two 16-bit

timer/counters. In addition, the SH79F082 provides external 256 bytes RAM, It also contains 8K bytes Flash memory block

both for program and data. Also the ADC and PWM timer functions are incorporated in SH79F082.

For high reliability and low cost issues, the SH79F082 builds in Watchdog Timer, Low Voltage Reset function. And

SH79F082 also supports two power saving modes to reduce power consumption.
