PRODUCT OVERVIEW
GENERAL DESCRIPTION
The SN8P1800 is an series of 8-bit micro-controller including SN8P1808. This series is utilized with CMOS technology
fabrication and featured with low power consumption and high performance by its unique electronic structure.
These chips are designed with the excellent IC structure including the large program memory OTP ROM, the massive
data memory RAM, one 8-bit basic timer (T0), two 8-bit timer counters (TC0, TC1), high performance of real time clock
timer (RTC) , a watchdog timer, up to seven interrupt sources (T0, TC0, TC1, SIO, INT0, INT1, INT2), an 8-channel
ADC converter with 8-bit/12-bit resolution, two channel PWM output (PWM0, PWM1), tw0 channel buzzer output (BZ0,
BZ1) and 8-level stack buffers.
Besides, the user can choose desired oscillator configurations for the controller. There are four oscillator configurations
to select for generating system clock, including High/Low speed crystal, ceramic resonator or cost-saving RC.
SN8P1800 series is a dual clock system using a hi-speed crystal for normal mode operation and an external low speed
crystal for slow mode, real time clock and LCD function.
