概述

Description

The PIC18F46K20-I/P is a mid‑range 8‑bit Microchip PIC microcontroller in a 40‑pin Plastic DIP package (the I/P suffix indicates a Plastic DIP through‑hole package). It uses the PIC18F core, runs up to about 40 MHz (roughly 10 MIPS), and contains on‑chip Flash program memory, RAM for data, and EEPROM for non‑volatile storage. It provides a rich peripheral set, including ADC (multiple channels), timers, PWM/ CCP modules, comparators, and serial communications (USART/UART, SPI, I2C/MSSP). It also supports standard features like watchdog timer and brown‑out/reset circuits. The device is programmed via ICSP and works with Microchip’s MPLAB X IDE and XC8/C18 toolchains. Typical applications include embedded control, data acquisition, sensor interfacing, small automation tasks, and consumer electronics. For exact memory sizes, pin count options, and peripheral counts, consult the datasheet for the specific package variant.

Features
