2. General Description
The SH79F3212 is a high performance 8051 compatible micro-controller, regard to its build-in Pipe-line instruction fetch
structure, that helps the SH79F3212 can perform more fast operation speed and higher calculation performance, if compare
SH79F3212 with standard 8051 at same clock speed.
The SH79F3212 retains most features of the standard 8051. These features include internal 256 bytes RAM, UART and INT2,
INT3 and INT4. In addition, the SH79F3212 provides external 1280 bytes RAM, Five 16-bit timer/counters T2-T5. It also
contains 32K bytes Flash memory block both for program and data.
Also the ADC, EUART, TWI, LPD, Touch key, LED Driver, PWM1/2 timer and CRC module functions are incorporated in
SH79F3212.
For high reliability and low power consumption, the SH79F3212 builds in Watchdog Timer, Low Voltage Reset function and
SCM function. And SH79F3212 also supports two power saving modes to reduce power consumption.
