2. General Description
The SH79F6488/SH79F6489 is a high performance 8051 compatible micro-controller, regard to its build-in Pipe-line instruction
fetch structure, that helps the SH79F6488/SH79F6489 can perform more fast operation speed and higher calculation
performance, if compare SH79F6488/SH79F6489 with standard 8051 at same clock speed.
The SH79F6488/SH79F6489 retains most features of the standard 8051. These features include internal 256 bytes RAM,
UART and INT0-2. In addition, the SH79F6488/SH79F6489 provides external 2304 bytes RAM, It also contains 64K bytes
Flash memory block both for program and data.
Some standard communication modes such as EUART and SPI are supported in the SH79F6488/SH79F6489. Also the Low
power LCD driver, 20-bit Σ-ΔADC, PGA, OP and PWM are incorporated in SH79F6488/SH79F6489. In additation, the
Universal Serial Bus (USB) interface is integrated into SH79F6489.
For high reliability and low cost issues, the SH79F6488/SH79F6489 builds in Watchdog Timer, Low Voltage Reset and System
Clock Monitor function. And SH79F6488/SH79F6489 also supports two power saving modes to reduce power consumption.
