The SN8P1808 is a RISC-like 8-bit micro-controller utilized CMOS technology and featured with low power consumption and high performance by its unique electronic structure. The device is designed with the excellent IC structure including the program memory up to 4K-word OTP ROM, data memory of 256-bytes RAM, one 8-bit basic timer (T0) with RTC (Real Time Clock) function, two 8-bit timer counters (TC0, TC1), a watchdog timer, seven interrupt sources (T0, TC0, TC1, SIO, INT0, INT1, INT2), an 8-channel 12-bit ADC converter, two channels PWM output (PWM0, PWM1), two channels buzzer output (BZ0, BZ1), 4-common by 24-segment LCD driver and 8-level stack buffers. There are four oscillator configurations to select for generating system clock, including High/Low Speed crystal, ceramic resonator or cost-saving RC. This device is a dual clock system using a hi-speed crystal for normal mode operation and an external low speed 32.768KHz crystal for slow mode, real time clock and LCD function.

The SN8P1829 enhanced with and Programmable Gain Instrumentation Amplifier with fully differential input, two sets of Operational Amplifiler and built-in Charge-Pump Regulator (CPR) 3.8V output / 5mA driven current. Besides, the user can choose desired oscillator configurations for the controller.
