PIC16F873T-04/SO

The PIC16F873T-04/SO is an 8‑bit Microchip PIC microcontroller from the PIC16F family, packaged in a 40‑pin Small‑Outline (SOIC) package. Core and peripherals:
- On‑chip flash program memory, RAM, and data EEPROM
- A/D converter (10‑bit, multiple channels)
- Timers (e.g., Timer0/Timer1) and CCP/PWM
- Serial interfaces: USART/UART and SPI/I2C (MSSP)
- I/O ports, interrupts, watchdog timer, and reset options
- Clock options: internal oscillator or external clock; code executed at Fosc/4 per instruction cycle
- Suitable for small to mid‑range embedded control, sensing, automation, and data acquisition
Development and tools:
- Supported by MPLAB X IDE and XC8 compiler
- In‑circuit programming via standard ICD/PGC–PGD interfaces
