HC18P018A0-SOP8-T

Shanghai Holychip Elec · Microcontroller Units (MCUs/MPUs/SOCs) · SOP-8

HC18P018A0-SOP8-T from Shanghai Holychip Elec, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Positive supply input for the MCU core and I/O.
2 PORTB2/T0CKI/CMPN/PCK/BAT bidirectional General-purpose I/O with programmable pull-up/pull-down, level-change interrupt and open-drain output. Alternate functions: Timer0 external clock input (Schmitt-trigger), comparator inverting input (CMPN), internal RC clock output in test mode (PCK), and battery/charging management input (BAT).
3 PORTB4 bidirectional General-purpose I/O with programmable pull-up/pull-down, level-change interrupt and open-drain output. Can be configured with an internal 1 kΩ current-limiting resistor; also usable as system-clock (Fosc) output via OPTION configuration.
4 PORTB5/PWM0 bidirectional General-purpose I/O with programmable pull-up/pull-down, level-change interrupt, open-drain output and configurable 1 A sink capability. Alternate function: PWM0 output, controlled by the PWMCT bits in the AUXR register.
5 PORTB3/MCLRB/VPP bidirectional General-purpose I/O with programmable pull-up/pull-down, level-change interrupt and open-drain output. Alternate functions: external reset input MCLRB (Schmitt-trigger, internal pull-up automatically enabled when in reset mode) and OTP programming high-voltage input (VPP).
6 PORTB0/INT0/PWM2/PGC bidirectional General-purpose I/O with programmable pull-up/pull-down, level-change interrupt, open-drain output and configurable 1 A sink capability. Alternate functions: INT0 external interrupt input with wake-up and selectable trigger edge, PWM2 output (controlled by AUXR.PWMCT), and PGC programming-clock input.
7 PORTB1/PWM1/PGD bidirectional General-purpose I/O with programmable pull-up/pull-down, level-change interrupt, open-drain output and configurable 1 A sink capability. Alternate functions: PWM1 output (controlled by AUXR.PWMCT) and PGD programming-data I/O.
8 VSS power_in Ground / negative supply return for the MCU.
