The SN8P2308 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 128-bytes RAM, one 8-bit basic timer (T0) with RTC (Real Time Clock) function, one 8-bit timer counters (TC0), one 16-bit timer (T1), a watchdog timer, four interrupt sources (T0, T1, TC0, INT0), two channel RFC (RC type AD Converter), one channel PWM output (PWM0), one channel buzzer output (BZ0), 4-common by 32-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.
