2. General Description
The SH79F7416 is a high performance 8051 compatible micro-controller.The SH79F7416 can perform more fast
operation speed and higher calculation performance, if compare SH79F7416 with standard 8051 at same clock speed.
The SH79F7416 retains most features of the standard 8051. These features include internal 256 bytes RAM, INT0-INT4.
In addition,SH79F7416 provides external4096 bytes RAM.It also contains 64Kbytes Flash memory block for program storage.
The SH79F7416 not only include many standard communication modules, such as EUART/TWI/SPI and so on, but also
include LCD diver, ADC,PCA, PWM timer, ect.
In addition, the SH79F7416 also have CRC module, built in it.
