SN8P2722

描述

The SN8P2722 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 2K-word OTP ROM, data memory of 128 bytes RAM, two 8-bit timer counters (T0, TC0), a watchdog timer, four interrupt sources (T0, TC0, ADC, INT0), one channel PWM output (PWM0), one channel Buzzer output (2K / 4K), 5-channel 12-bit ADC converter, 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 internal 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.
