2. General Description
The SH79F6441 is high performance 8051 compatible micro-controller. The SH79F6441 can perform more fast operation
speed and higher calculation performance, if compare SH79F6441 with standard 8051 at same clock speed.
The SH79F6441 retains most features of the standard 8051. These features include internal 256 bytes RAM, Three UART and
INT0, INT1, INT2, INT3, INT4. In addition, SH79F6441 provides external 2816 bytes RAM. It also contains 64K bytes Flash
memory block for program storage.
The SH79F6441 not only include many standard communication modules, such as EUART, TWI, SPI and so on, but also
include 12bit ADC, PWM timer, ect.
In addition, the SH79F6441 also have CRC module, Logic configurable module (LCM) built in it.
For high reliability and low cost issues, the SH79F6441 builds in Watchdog Timer, Low Voltage Reset function and system clock
monitor. And SH79F6441 also supports two power saving modes to reduce power consumption.
