PIC12C671-04/SM

Introduction (PIC12C671-04/SM)
- What it is: An 8‑bit Microchip PIC microcontroller in an 8-pin package (PIC12C671 family). The -SM suffix denotes a small-outline/MSD package option.
- Core features: Flash program memory (about 1K words), typical ~64 bytes RAM, 6 I/O pins (GP0–GP5), internal oscillator, Timer0, Watchdog Timer, and MCLR/reset. No data EEPROM; no ADC or advanced peripherals in this device variant.
- Power and timing: Low-power operation, typically 2–5.5V supply. Uses a simple instruction set with 14‑bit wide instruction words.
- Package options: Commonly available in DIP-8 (PDIP) and SOIC-8; -SM indicates a surface-mount version.
- Development: Programmed via Microchip MPLAB X IDE with PICKit or similar programmer/debugger.
- Applications: Small, cost-sensitive control tasks such as LED/relay control, simple switch debouncing, timing applications, basic sensor interfacing in compact devices.
Note: Exact memory size, RAM, and peripheral set can vary by device revision; consult the latest datasheet for your part variant.
