概述

Description

PIC16F873T-04/SO is an 8‑bit Microchip PIC microcontroller from the PIC16F873 family. The “-SO” suffix indicates a 40‑pin surface‑mount (SOIC) package.
Key basics:
- Core: Harvard architecture, 8‑bit instruction set.
- Program memory: up to about 8K x 14‑bit Flash.
- Data memory: RAM several hundred bytes; EEPROM storage (tens to hundreds of bytes).
- Peripherals: timers (8‑bit and 16‑bit), ADC (multi‑channel, 10‑bit), CCP/PWM, MSSP (SPI/I2C), watchdog timer.
- I/O: multiple I/O pins on PORTA/PORTB with useful multifunctions.
- Operating voltage: typically 2.0–5.5 V; clock options include external oscillators up to ~20 MHz (Fosc).
- Programming: ICSP/In‑Circuit Serial Programming; various reset and safety features.
Applications: general‑purpose control, sensing, small embedded projects.
Note: exact memory sizes and peripheral counts vary by variant; consult the datasheet/product page for precise specs and pinout.
