HE8P1702A 8-bit microcontroller with 8-bit ADC circuit

1. GENERAL DESCRIPTION

he HE8P1702A is an 8-bit micro-controller 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 program memory up to 1K-word OTP ROM, 256 bytes of the data memory, one 8-bit T0 basic timer, two 8-bit

timer/event counters, a watchdog timer, seven interrupt sources (T0, TC0, TC1, SIO, INT0 ~ INT2), an 8-ch ADC converter with 8
bits resolution, a 7-bit DAC converter, 2-ch PWM output, 33 I/O pins and 8 levels stack buffer. Besides, the user can choose
desired oscillator configurations for the controller. There are four oscillator configurations to select for generating system clock,
including Hi/Low Speed crystal, ceramic resonator or cost-saving RC.
