Key Features

  • 8-bit PIC16 CMOS core operating at up to 4 MHz with low-power 3.0 V minimum supply compatibility
  • 18-pin PDIP package enabling breadboard and through-hole prototyping without special tooling
  • On-chip timers and I/O ports supporting simple control, sensing, and communication tasks
  • OTP (one-time programmable) EPROM for cost-effective production programming in high-volume applications
  • Wide operating voltage range supporting both 3.3 V and 5 V system environments

Applications

The PIC16C558-04/P is a legacy 8-bit microcontroller suited for simple control tasks such as keypad scanning, relay sequencing, and LED display driving in consumer appliances and industrial panels. Its 18-pin PDIP package makes it easy to integrate into replacement or repair boards where through-hole assembly is preferred over surface-mount. The device is commonly used in cost-sensitive, low-complexity embedded designs where a small PIC core running at 4 MHz provides sufficient processing power without the overhead of a larger microcontroller family.

Frequently Asked Questions

At what clock frequency and supply voltage does the PIC16C558-04/P operate?

The PIC16C558-04/P runs at up to 4 MHz and can operate from a minimum supply of 3.0 V, making it compatible with both 3.3 V and 5 V system architectures commonly found in industrial control and consumer electronics boards.

How does the 18-pin PDIP package of the PIC16C558-04/P simplify prototyping and repair?

The 18-pin PDIP (Plastic Dual In-Line Package) fits standard 0.1-inch breadboards and through-hole PCB footprints, allowing engineers to prototype circuits without SMT soldering equipment and enabling straightforward manual replacement of defective units during field repair of legacy equipment.

Which application categories best match the PIC16C558-04/P given its 8-bit architecture and peripheral set?

This 8-bit PIC16 device is well matched to simple control tasks such as 4 MHz keypad polling, relay driving, buzzer control, and basic serial communication in appliances, industrial timers, or educational kits where code size stays below the on-chip EPROM capacity and processing requirements are modest.

Is the PIC16C558-04/P RoHS compliant, and what should buyers consider regarding its production lifecycle?

The PIC16C558-04/P is listed as RoHS compliant (Pb-free) per its JESD-609 code, but its YTEOL rating of 3 indicates a limited remaining active production lifetime; buyers procuring for long-horizon designs should confirm current stock availability and consider modern pin-compatible PIC16F replacements running at up to 32 MHz for new designs.
