The SN8P2318 is a RISC-like high performance and low power consumption 8-bit micro-controller. 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 timer counters (T0) , one 8-bit counters / timers (TC0), a watchdog timer, five interrupt sources (T0, TC0, T1, INT0, INT1), 4*32 LCD Driver (128dots), one channel programmable PWM and IR carry signal, 16-bit timer with capture timer function, RFC function, and 8-level stack buffers. There are four oscillator configurations to select for generating system clock, including external High/Low Speed crystal, ceramic resonator or external cost-saving RC, an internal 16MHz PLL oscillator for system clock. The external low speed crystal/ceramic resonator/RC oscillator support slow mode controlled by programming.
