Key Features
- 8-bit PIC16 core at up to 20 MHz with 2 V minimum supply enables high-speed operation at low voltage for battery-powered and energy-harvesting designs
- 768 bytes of flash program memory in an 18-pin SOIC-18 package provides a cost-effective, re-erasable solution for simple state machine and I/O control firmware
- Pb-free RoHS-compliant construction with mature PIC16 instruction set allows direct migration from legacy OTP/EPROM PIC16 designs with minimal firmware changes
Applications
The PIC16F54-I/SO is designed for simple 8-bit embedded control applications such as keypad interfaces, LED drivers, relay sequencers, and toy logic controllers where minimal flash memory and low cost per unit are the primary design constraints. Its 2 V minimum supply at 4 MHz makes it suitable for 2-cell battery-powered products like remote controls, simple sensors, and low-power timers. The familiar PIC16 architecture also supports rapid firmware development in legacy industrial maintenance and small-volume OEM product lines.

Frequently Asked Questions
At what minimum supply voltage can the PIC16F54-I/SO operate and at what clock speed does it function at 2 V?
The PIC16F54-I/SO operates at a minimum supply voltage of 2 V at 4 MHz, allowing it to run directly from 2 alkaline or NiMH cells without a boost regulator. At higher supply voltages up to 5.5 V, the device supports its full maximum clock frequency of 20 MHz, providing design flexibility for both low-power battery and regulated 3.3 V or 5 V system applications.
How much program memory does the PIC16F54-I/SO provide and what types of control logic fit within 768 bytes of flash?
The PIC16F54-I/SO contains 768 bytes of flash program memory, equivalent to approximately 512 PIC instructions. This capacity comfortably holds simple state machines, button debounce routines, LED pattern sequencers, and serial communication handlers. Applications with more than 50–100 lines of C code may need to optimize aggressively or migrate to a larger PIC16F variant with 1 KB or more of flash.
For a legacy board replacement using EPROM-based PIC16C devices, how compatible is the PIC16F54-I/SO as a flash drop-in?
The PIC16F54-I/SO is pin-compatible with EPROM-based PIC16C5x devices in the 18-pin SOIC footprint and shares the same PIC16 instruction set. Flash program memory replaces UV-erasable EPROM, eliminating the need for erasure equipment and reducing programming cycle time to seconds rather than minutes. Firmware migrated from PIC16C5x runs without modification in most cases, making it a practical and faster-to-reprogram substitute.
With a 5-week factory lead time, how should engineering teams manage procurement of PIC16F54-I/SO for a new product introduction?
The PIC16F54-I/SO has a 5-week factory lead time from Microchip, requiring purchase orders to be placed at least 7 weeks before first-article assembly to allow for shipping and inspection. For new product introduction, ordering a pilot batch of 500–1000 units alongside the engineering sample order and establishing a blanket PO for production quantities helps lock in pricing and avoid delays when the design transitions from prototype to volume build.
