Applications
PIC16F57-I/SO targets high-volume, cost-sensitive embedded applications such as consumer remote controls, simple motor sequencers, LED lighting controllers, and home appliance button matrices. Its 2 V minimum supply supports direct operation from 2 AA batteries, and the 20 MHz clock handles UART communication and PWM generation for low-power actuator control. The 28-pin SOIC package and 1-week lead time make it attractive for production designs needing fast replenishment.

Frequently Asked Questions
Can PIC16F57-I/SO run directly from 2 AA batteries and what clock speed is achievable at that voltage?
Yes. PIC16F57-I/SO operates from a 2 V minimum supply at up to 4 MHz, which matches the nominal voltage of 2 freshly charged AA alkaline batteries (approximately 3 V) and remains functional as they discharge to 2 V. At 2 V and 4 MHz, the 8-bit PIC16 core can handle simple control tasks such as button scanning, LED control, and serial communication without any voltage regulation circuitry.
How many GPIO pins does PIC16F57-I/SO provide and can it directly drive LED arrays without external drivers?
PIC16F57-I/SO provides 24 I/O pins in the 28-pin SOIC package. Each GPIO pin can typically source or sink up to 25 mA, with a total package current limit. This allows direct driving of small LED arrays — for example, 8 LEDs at 5 mA each requires only 40 mA total, well within package limits. For larger arrays, an external driver or shift register is recommended, but for simple 4-digit LED indicators PIC16F57-I/SO GPIO is sufficient.
When is PIC16F57-I/SO preferred over a PIC16F with an on-chip ADC for a simple logic control application?
PIC16F57-I/SO has no ADC, making it optimal for purely digital control tasks where analog measurement is not needed — such as button matrix scanning, relay sequencing, and UART-based command processing. Removing the ADC reduces die size and cost compared to ADC-equipped variants. For a high-volume consumer product processing only digital inputs (switches, encoders) and digital outputs (relays, LEDs), PIC16F57-I/SO's lower unit price at 20 MHz clock speed provides the best cost-to-performance ratio.
What procurement advantages does PIC16F57-I/SO offer compared to longer-lead-time microcontrollers?
PIC16F57-I/SO carries only a 1-week factory lead time from Microchip Technology — significantly shorter than the 7–13 week lead times common for more complex MCUs. This makes it attractive for contract manufacturers needing rapid replenishment and for designs recovering from component shortages. Its 8-year YTEOL and RoHS-compliant Pb-free SOIC-28 packaging ensure continued availability for multi-year production programs.
