PIC16F677T-I/SO

The PIC16F677T-I/SO is Microchip’s 8‑bit PIC microcontroller from the PIC16F677 family, packaged in a Small Outline (SOIC) form factor with industrial temperature range (-40°C to +125°C). The “T”/suffixes indicate specific packaging/tape options; verify exact details in the datasheet for this variant.
Key points:
- On‑chip flash memory for program storage and RAM (data) with optional EEPROM data retention.
- On‑board clock/oscillator, normal I/O ports, and interrupt support.
- A set of built‑in peripherals; exact peripherals (timers, serial interfaces, analog features) vary by variant, so check the datasheet for this specific device.
- Suitable for compact embedded tasks: simple control loops, sensor interfacing, small automation projects.
Recommendation: consult the PIC16F677T-I/SO datasheet for exact memory sizes, I/O count, available peripherals, timing, and package details.

Equivalent products: Within Microchip’s PIC16F6x7 family, the closest equivalents are PIC16F676 and PIC16F677 (and their “A” variants: PIC16F676A, PIC16F677A). For the same 28‑pin SOIC industrial-temp packaging, use PIC16F677I/SO or PIC16F676I/SO. There isn’t an exact cross‑part; check Microchip’s Cross Reference tool for precise substitutions by package/temperature.
