PIC12F1822T-I/MF

The PIC12F1822T-I/MF is an 8-bit Microchip PIC microcontroller in the PIC12F family, designed for small, low-cost embedded control tasks. It comes in an 8-pin package and is intended for industrial-temperature operation with a molded (MF) package option. The “T-I” suffixes indicate packing/temperature specifics and RoHS-compliant packaging.
Key points:
- Small, inexpensive MCU with an 8-pin footprint ideal for simple sensors, switches, LEDs, and small I/O control.
- Built-in Flash program memory, RAM, and EEPROM suitable for compact firmware.
- Integrated peripherals such as timers, watchdog, I/O ports, and a memory-mapped peripheral set (including serial/I2C/SPI options on many PIC12F parts).
- Operates from a low-voltage supply (typical 2.0–5.5 V) with various clock options and a straightforward development flow.
Development: use Microchip MPLAB X IDE with XC8 compiler; programs are loaded via ICSP.
