2. General Description
The SH79F161B is a high performance 8051 compatible micro-controller, regard to its build-in Pipe-line instruction fetch
structure, that helps the SH79F161B can perform more fast operation speed and higher calculation performance, if compare
SH79F161B with standard 8051 at same clock speed.
The SH79F161B retains most features of the standard 8051. These features include internal 256 bytes RAM, EUART and
Int0-3. In addition, the SH79F161B provides external 512 bytes RAM, It also contains 16K bytes Flash memory block both for
program and data. Also the ADC and PWM timer functions are incorporated in SH79F161B.
For high reliability and low cost issues, the SH79F161B builds in Watchdog Timer, System Clock Monitor, and Low Voltage
Reset function. And SH79F161B also supports two power saving modes to reduce power consumption.
