What are the key features of PIC16C54C-04/SO?
- 8-bit PIC16 RISC core with 33-instruction set running at up to 4 MHz for deterministic low-complexity control logic
- 18-pin SOIC-18 package with 12 I/O pins enabling compact PCB layouts in cost-sensitive consumer and industrial products
- OTP (one-time programmable) program memory suited for high-volume production where code lock-down and low unit cost are priorities
What is PIC16C54C-04/SO used for?
The PIC16C54C-04/SO is commonly deployed in simple consumer appliances, remote controls, and low-cost timers where a small 8-bit controller with minimal peripherals and 4 MHz maximum clock is sufficient. Its 18-pin SOIC package and OTP memory make it attractive for high-volume manufacturing of toys, white goods controls, and LED drivers where programming occurs once during production. Legacy industrial equipment maintenance also benefits from this device, as it remains available as a direct replacement for aging PIC16C54 designs.

Frequently Asked Questions
What is the maximum clock frequency of the PIC16C54C-04/SO and what oscillator types does it support?
The PIC16C54C-04/SO runs at a maximum clock frequency of 4 MHz and supports external crystal, RC oscillator, and external clock input modes, giving designers flexibility to balance accuracy and cost in simple timer and control circuits.
How does the PIC16C54C-04/SO compare to PIC16F devices when choosing for a new low-complexity design?
The PIC16C54C-04/SO uses OTP memory and lacks flash re-programmability, in-circuit serial programming, and ADC channels present in PIC16F parts; for new designs PIC16F628A or similar offers 10-bit ADC and flash at comparable cost, but PIC16C54C-04/SO suits legacy replacement in 4 MHz applications.
What I/O count does the PIC16C54C-04/SO provide and how are the pins arranged in the SOIC-18 package?
The PIC16C54C-04/SO provides 12 I/O pins organized in two ports across the 18-pin SOIC-18 footprint, with VDD, VSS, OSC1, and OSC2 consuming 4 pins, leaving sufficient GPIOs for small relay-driver, keypad-scanner, and LED-matrix control tasks.
Is the PIC16C54C-04/SO RoHS compliant and what lead-free packaging options are available?
Yes, the PIC16C54C-04/SO carries a Pb-free code confirming RoHS compliance; Microchip ships it in tape-and-reel or tube formats for SOIC-18, with a factory lead time of approximately 5 weeks for volume orders.
