2. General Description

The SH79F1640 is a high performance 8051 compatible micro-controller. Regard to its build-in Pipe-line instruction fetch
structure, that helps the SH79F1640 can perform more fast operation speed and higher calculation performance, if compare
SH79F1640 with standard 8051 at same clock speed.
The SH79F1640 retains most features of the standard 8051. These features include internal 256 bytes RAM, Two UART and
INT0, INT1, INT2, INT3, INT4. In addition, SH79F1640 provides external 1280 bytes RAM. It also contains 16K bytes Flash
memory block for program storage.
The SH79F1640 not only include many standard communication modules, such as EUART, TWI and so on, but also include
dimming LED, LCD diver, 12bit ADC, PWM timer, etc.
In addition, the SH79F1640 also have Touch Key module, CRC module, Logic configurable module (LCM) built in it.
For high reliability and low cost issues, the SH79F1640 builds in Watchdog Timer, Low Voltage Reset function and system
clock monitor. And SH79F1640 also supports two power saving modes to reduce power consumption.
