General Description The SH79F166A is a high performance 8051 compatible micro-controller, regard to its build-in Pipe-line instruction fetch structure, that helps the SH79F166A can perform more fast operation speed and higher calculation performance, if compare SH79F166A with standard 8051 at same clock speed. The SH79F166A retains most features of the standard 8051. These features include internal 256 bytes RAM, UART and Int0-3.In addition, the SH79F166A provides external 256 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 SH79F166A. For high reliability and low cost issues, the SH79F166A builds in Watchdog Timer, Low Voltage Reset function. And SH79F166A also supports two power saving modes to reduce power consumption. 1 V2.2 3.
