Introduced the features and characteristics of Microchip PIC16C6X 8-bit CMOS microcontrollers, including high-performance RISC CPU, 35 single-word instructions, 20MHz clock input, eight-level deep hardware stack, etc.
The PIC16C6X family is a low‑cost, high‑performance 8‑bit CMOS microcontroller line from Microchip. It offers a RISC core, up to 35 instructions, a deep hardware stack, and a range of peripherals such as timers, capture/compare/PWM modules, and serial interfaces.
The devices are available in multiple voltage ranges (2.5 V‑6.0 V), package types, and memory sizes up to 8 K × 14‑bit program memory. Features include watchdog timer, brown‑out reset, sleep mode, and in‑circuit serial programming, making them suitable for automotive, appliance, and low‑power sensor applications.
