General Description
The SH79F081 is a fast 8051 compatible micro-controller with a redesigned CPU of no wasted clock and memory cycles.
Typically, it will be faster than and exhibit better performance than the traditional 8051 at the same oscillator frequency.
The SH79F081 retains most features of the standard 8051. These features include internal 256 bytes RAM and two 16-bit
timer/counters. In addition, the SH79F081 provides another 16-bit timer/counter compatible with 8052. It contains a 8K Bytes
Flash memory block for program and data.
Some standard serial communication modes such as EUART and SPI are supported in SH79F081. Also the ADC together
with built-in digital compare function and PWM timers are incorporated in SH79F081.
It also provides the following standard features: on-chip watchdog timer, low voltage reset function. It provides two power saving
modes to reduce the power consumption.
