• Integrated 2 KB EPROM for non-volatile program storage
• Built-in power-on reset and watchdog timer for system reliability
• Eight-level deep hardware stack supporting complex subroutine handling

Microcontrollers Applications

• Battery charger controllers requiring low-cost analog interfaces
• Threshold detection circuits utilizing internal voltage references
• White home appliance control modules
• General-purpose embedded logic applications

Microcontrollers Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm the specific suffix matches the requested SSOP-20 package and 20 MHz speed grade. Check for end-of-life status or obsolescence notices prior to procurement planning. Ensure environmental compliance documentation aligns with project requirements.

Microcontrollers Selection Notes

Select this model when EPROM reprogrammability is required for prototyping or low-volume production. Compare against PIC16F variants if EEPROM data retention or higher pin counts are necessary. Evaluate the 13 available I/O lines against interface requirements. Consider the 20 MHz processing speed relative to real-time control demands.

Microcontrollers Part Context

This component belongs to the PIC16C62x series, which represents an earlier generation of 8-bit microcontrollers based on ROM/EPROM technology. The series utilizes a Harvard architecture with separate instruction and data buses. It serves as a foundational platform for cost-sensitive embedded designs before the widespread adoption of Flash-based PIC16F counterparts.
