Key Features
- Ultra-compact SOIJ-8 package with 6 configurable I/O pins enabling minimal-footprint control logic in space-constrained consumer products and replacement timing circuits
- Internal 4 MHz RC oscillator option eliminates external crystal and two load capacitors, reducing BOM cost and simplifying PCB layout for cost-sensitive high-volume applications
- One-time programmable (OTP) 512-word Flash with watchdog timer and power-on reset provides reliable standalone control for fixed-function appliance timers and remote-control decoders
Applications
The PIC12C508 is suited for simple timing, sequencing, and logic-replacement applications in toys, appliance controllers, and white-goods where a full 8-pin MCU replaces discrete 555-timer or logic-gate circuits at lower cost and higher integration. Its 4 MHz internal oscillator and 6 I/O lines handle LED blink sequences, button debounce, and relay drive for low-volume OEM designs where board area under 10 mm x 10 mm is a hard constraint. Legacy industrial panels and replacement control boards also use the PIC12C508 to replicate fixed timing behavior of discontinued DIP-8 logic ICs.

Frequently Asked Questions
How much program memory and RAM does the PIC12C508 offer, and is it sufficient for simple timer or sequencer firmware?
The PIC12C508 provides 512 words (12-bit instruction width) of one-time-programmable program memory and 25 bytes of data RAM, which is sufficient for a 4 MHz firmware image implementing LED blink patterns, button debounce routines, and relay sequencing with up to 6 I/O pins in a single interrupt-driven loop.
Does the PIC12C508 require an external crystal, and what clock options are available?
The PIC12C508 includes an internal RC oscillator calibrated to approximately 4 MHz, eliminating the need for an external crystal and 2 load capacitors, which saves at least 3 components and approximately 10 mm² of PCB space in compact 8-pin SOIJ-8 designs for toy controllers, remote controls, and appliance timers.
How many I/O pins does the PIC12C508 provide, and can they be individually configured as inputs or outputs?
The PIC12C508 has 6 general-purpose I/O pins (GP0 through GP5) on its 8-pin SOIJ-8 package, each independently configurable as input or output via the TRIS register, supporting mixed-signal tasks such as 3 output drive lines for LEDs and 3 input sense lines for buttons or sensor contacts in a 2.5 V to 5.5 V supply system.
What makes the PIC12C508-04/SM suitable as a direct replacement for discrete 555-timer or logic-gate circuits?
The PIC12C508 replaces a 555 timer plus external RC network with programmable timing accuracy within ±1% using its 4 MHz internal oscillator, and its 6 I/O lines can implement NOR or NAND gating in firmware, eliminating at least 2 discrete ICs and 5 passive components while consuming under 2 mA active current at 4 MHz on a 5 V rail.
What supply voltage range and standby current does the PIC12C508 support for battery-operated fixed-function controllers?
The PIC12C508 operates from 2.5 V to 5.5 V and draws typically 2 mA in active mode at 4 MHz and under 10 µA in sleep mode, enabling multi-year coin-cell operation for appliance remote controls and fixed-sequence timers that activate only on button press or periodic wake events triggered by the internal watchdog timer.
