The SN8P2602C 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 1K-word OTP ROM, data memory of 48 bytes RAM, one 8-bit timer counters (T0+RTC) , one 8-bit counters / timers (TC0), a watchdog timer, three interrupt sources (T0, TC0, INT0), one channel programmable PWM, one channel 2K/4K buzzer output, 40mA high sink current GPIO pin (P5.0~P5.3, P5.5), and 4-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 RC oscillator for system clock and includes an internal low frequency RC oscillator for slow mode controlled by programming.
