- 4 MHz maximum clock frequency with industrial-temperature rating from -40°C to +85°C for harsh environments
- Low-cost OTP (one-time programmable) 768-byte Flash equivalent for high-volume, cost-sensitive production runs
- PIC12 core architecture with just 33 single-word instructions for easy, fast firmware development
Applications
The PIC12C508AT-04I/SM targets simple, cost-sensitive control tasks such as LED sequence controllers, appliance timer circuits, and relay driver logic where minimal I/O and low clock speed are sufficient. Its 8-pin SOIC footprint fits into extremely space-constrained designs such as sensor dongles, battery-powered remotes, and cable-end smart accessories. The industrial temperature rating of -40°C to +85°C enables deployment in outdoor and automotive accessory applications where temperature fluctuates widely.

Frequently Asked Questions
How much program memory and RAM does the PIC12C508AT-04I/SM provide, and what can fit in it?
The PIC12C508AT-04I/SM provides 768 bytes (512 x 12-bit words) of OTP program memory and 25 bytes of RAM. This is sufficient for simple state machine firmware, LED blinking sequences, debounce logic, or single-sensor threshold comparators, all running at up to 4 MHz clock frequency with the compact PIC12 instruction set.
For a battery-powered remote control design, how does the PIC12C508AT-04I/SM's 8-pin package simplify the hardware?
The SOIC-8 package exposes 6 general-purpose I/O pins in a body measuring approximately 5 mm x 4 mm, small enough to fit inside coin-cell battery holders. Running at 4 MHz from a 2.5 V to 5.5 V supply, the device can directly drive IR LED outputs, read button inputs, and implement a simple IR encoding protocol without any additional ICs, keeping BOM cost and board area minimal.
When would a designer choose PIC12C508AT-04I/SM over a more capable PIC12F series part?
PIC12C508AT-04I/SM is chosen for ultra-high-volume, cost-driven production where OTP programming at the factory is acceptable and the firmware is fixed. At 4 MHz with 768 bytes of OTP memory, it undercuts Flash-based PIC12F parts in unit cost. Designs that do not need ADC, EEPROM, or field reprogramming and run at temperatures between -40°C and +85°C are ideal candidates.
What serial communication capabilities does the PIC12C508AT-04I/SM support for interfacing with other devices?
The PIC12C508AT-04I/SM does not include hardware UART, SPI, or I2C peripherals. However, its 6 I/O pins and 4 MHz clock support software-bitbanged 2-wire serial protocols at low baud rates such as 9600 bps UART or 100 kHz I2C, making it adequate for simple sensor readout or LED driver communication tasks where hardware peripherals are not required.
