2. General Description
The SH77P1651/SH77P1652 is a high performance 8051 compatible micro-controller, compare with standard 8051 at the
same clock frequency, the SH77P1651/SH77P1652 performs more fast operation speed and higher calculation performance.
The SH77P1651/SH77P1652 retains most features of the standard 8051. These features include internal 256 bytes RAM, 1
UART and 1 external interrupt (8 Multiplexed Input Channels).
In addition, the SH77P1651/SH77P1652 builds in UART standard communication module, LCD voltage regulator circuit,
capacitor bias circuit, resistor bias circuit and 1 PWM, etc.
For high reliability and low cost issues, the SH77P1651/SH77P1652 builds in Watchdog Timer, Low Voltage Reset function and
system clock monitor function, in addition, SH77P1651/SH77P1652 supports two power saving modes to reduce power
consumption.

RESET
The device will be reset by A low voltage on this pin longer than 10us, an internal
I resistor about 30kΩ to VDD, So using only an external capacitor to GND can cause a
power-on reset
