Overview
Description
The PIC17C44-16/PT is an 8‑bit Microchip PIC microcontroller from the PIC17C family. It uses a Harvard architecture with on‑chip program memory and RAM and provides a basic set of peripherals for embedded control tasks. Typical features (per the family) include: I/O ports, one or more timers, interrupt support, a watchdog timer, and a serial interface (SCI/SPI); there are oscillator options and power‑management modes. The -16/PT suffix denotes a specific packaging/variant of the device (for example, a Plastic DIP package with a particular speed grade). Exact memory sizes, peripheral set, input voltage range, and pinout depend on the exact revision of the PIC17C44, so you should consult the official datasheet for precise figures.
Common use: straightforward, low‑to‑moderate complexity control applications requiring simple timing, I/O, and serial communication.
Getting started: obtain the datasheet and user manual, review the pinout and memory/register map, choose an oscillator mode, and develop with MPLAB X IDE and a programmer (e.g., PICKit).
