PIC12C508 and PIC12C509 are 8-bit microcontrollers packaged in 8-lead packages. They are based on the Enhanced PIC16C5X family.
The document describes the PIC12C5XX family, which includes the PIC12C508 (512x12 program memory) and PIC12C509 (1Kx12 program memory). These devices utilize a high-performance RISC CPU with 33 single-word instructions and are available in OTP versions for cost-effective production.
| Program Memory (PIC12C508) | 512x12 |
|---|---|
| Program Memory (PIC12C509) | 1Kx12 |
| Maximum Operating Speed | 4 MHz |
| Instruction Cycle Time (1s) | 250 ns |
The device supports INTRC (Internal 4 MHz RC), EXTRC, XT (Standard crystal/resonator), and LP (Power saving low frequency crystal) modes.
Yes, it includes a Watchdog Timer (WDT) with its own on-chip RC oscillator for reliable operation.
The typical standby current is less than 1 pA.
