Introduced the features and characteristics of the PIC16F5X series
The PIC16F5X family from Microchip Technology is a low‑cost, high‑performance 8‑bit Flash‑based CMOS microcontroller series. It uses a RISC core with only 33 single‑word instructions, most of which execute in a single cycle, and offers a two‑level deep hardware stack, multiple oscillator options, and a range of low‑power features such as Power‑on Reset, Watchdog Timer, and Sleep mode.
The datasheet details memory organization (512‑2 K words of Flash, 25‑134 bytes of SRAM), pin configurations for various 18‑ to 44‑pin packages, and electrical specifications including a 20 MHz maximum clock, 170 µA operating current at 2 V/4 MHz, and 500 nA standby current. It also lists temperature ranges, voltage ranges, and I/O capabilities for industrial and extended‑temperature parts.
| Maximum operating frequency | 20 MHz |
|---|---|
| Flash program memory (PIC16F54) | 512 × 12 bits |
| Flash program memory (PIC16F57/59) | 2048 × 12 bits |
| Standby current (typical) | 500 nA @ 2 V |
| Supply voltage range (industrial) | 2.0 V to 5.5 V |
| Operating temperature range (industrial) | -40 °C to 85 °C |
| I/O pins | 12 / 20 / 32 pins |
The PIC16F5X can operate up to 20 MHz.
Typical standby current is 500 nA at 2 V.
