This data sheet details the features and characteristics of the PIC16C5X series, including 33 single-word instructions, single-cycle instructions, 200-nanosecond instruction cycle, 18 to 28 pins, 12 to 20 I/O ports, 384 to 2048 bytes of EPROM/ROM, and 25 to 73 bytes of RAM.
The PIC16C5X family from Microchip Technology is a low‑cost, high‑performance 8‑bit CMOS microcontroller series that uses EPROM or ROM program memory. It employs a RISC core with 33 single‑word instructions, all executing in a single 200 ns cycle, and offers a range of oscillator options and power‑saving modes.
The document includes detailed pin diagrams for PDIP, SOIC and SSOP packages, electrical characteristics for each device variant, memory organization tables, I/O port descriptions, Timer0 module information, special CPU features, the full instruction set summary, and packaging data. It also provides ordering information and references to development tools and programming services.
