2. General Description
The SH79F3283 is a high performance 8051 compatible micro-controller, regard to its build-in Pipe-line instruction fetch
structure, that helps the SH79F3283 can perform more fast operation speed and higher calculation performance, if compare
SH79F3283 with standard 8051 at same clock speed.
The SH79F3283 retains most features of the standard 8051. These features include internal 256 bytes RAM, UART and INT0,
INT1, INT2 and INT3. In addition, the SH79F3283 provides external 1280 bytes RAM, Four 16-bit timer/counters T2-T5. It also
contains 32K bytes Flash memory block both for program and data.
Also the ADC, EUART, SPI, LCD Driver, PWM timer and CRC module functions are incorporated in SH79F3283.
For high reliability and low power consumption, the SH79F3283 builds in Watchdog Timer, Low Voltage Reset function and
SCM function. And SH79F3283 also supports two power saving modes to reduce power consumption.
