描述 Description

GENERAL DESCRIPTION
The SN8P1702A/SN8P1703A is a series of 8-bit micro-controller. This chip is utilized with CMOS technology fabrication and featured with low power consumption and high performance by its unique electronic structure. This chip is designed with the excellent IC structure including the large program memory OTP ROM, the massive data memory RAM, two 8-bit timer counters (TC0, TC1), a watchdog timer, three interrupt sources (TC0, TC1, INT0), an 4-channel ADC converter with 8-bit/12-bit resolution, two channels high speed PWM output (PWM0, PWM1), two channels buzzer output (BZ0, BZ1) and 8-level stack buffers.
Besides, the user can choose desired oscillator configurations for the controller. There are four oscillator configurations to select for generating system clock, including High/Low Speed crystal, ceramic resonator or cost-saving RC. This series also includes an internal RC oscillator for slow mode controlled by programming.SN8P1702A/SN8P1703A FEATURES
