HE8P1700A 8-bit microcontroller with 8-bit ADC circuit
1. GENERAL DESCRIPTION
he HE8P1700A 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 4K-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.
2. FEATURES
Memory configuration Seven interrupt sources:
OTP ROM size: 4096 * 16 bits. Four internal interrupts: TO, TC0, TC1, SIO
RAM size: 256 * 8 bits. Three external interrupts: 1NT0 - INT2
I/Opin configuration (Total 33 pins) Eight levels stack buffer
One input port: 3 pins with wakeup function. An 8-channel ADC converter with 12-bit resolution.
Three Input/output ports: 22 pins for general purpose. A DAC converter with 7 bits resolution.
One input/output port: 8 pins shared with ADC inputs. Two 8-bit PWM output (PWM0,PWM1)
An 8-bit basic timer. Two Buzzer output (TC0,TC1)
Two 8-bit timer/event counters. A watchdog timer.
Built-in internal RC Low Clock 16KHz
59 powerful instructions Crystal type: speed up to 20 MHz.
