Microchip PIC16C63A/65B/73B/74B Datasheet
The PIC16C63A/65B/73B/74B devices are low‑cost, high‑performance 8‑bit CMOS microcontrollers in Microchip's mid‑range PIC16CXX family. They offer a 35‑instruction RISC core, eight‑level hardware stack, multiple timer modules, SSP, USART, and up to eight‑channel A/D conversion. Power‑saving options include Power‑on Reset, Watchdog Timer, and a SLEEP mode.
These devices are offered in several package types (PDIP, SOIC, TQFP, etc.) with 22 or 33 I/O pins depending on the variant, and operate over a 2.5 V to 5.5 V range at up to 20 MHz. They target applications such as security, remote sensing, appliance control and automotive, where low power consumption and small footprint are critical.
