Frequently Asked Questions

What is the maximum clock frequency of the PIC16F628-04/SS?

The PIC16F628-04/SS has a maximum clock frequency of 4 MHz, as indicated by the -04 speed variant suffix. This frequency is suitable for low to moderate speed embedded control tasks such as timer management, serial communication, and sensor data processing in compact 8-bit designs.

Does the PIC16F628-04/SS include EEPROM data memory?

Yes, the PIC16F628-04/SS includes on-chip EEPROM data memory for non-volatile storage of calibration constants, configuration data, and user settings. This eliminates the need for external EEPROM components in many embedded designs, reducing BOM cost and PCB complexity.

What package does the PIC16F628-04/SS use?

The PIC16F628-04/SS is available in an SSOP-20 (Shrink Small Outline Package) with 20 pins. This compact surface-mount package is suitable for high-density PCB designs and is compatible with standard SMT reflow assembly processes in both prototype and production manufacturing environments.

Does the PIC16F628-04/SS have an ADC?

No, the PIC16F628-04/SS does not include an analog-to-digital converter (ADC). However, it does feature on-chip analog comparators that allow comparison of external voltages to internal or external references, providing limited analog sensing capability without a full ADC.

What is the typical lead time for the PIC16F628-04/SS?

The PIC16F628-04/SS has a factory lead time of approximately 5 weeks for volume orders. It was introduced in June 1999 and remains available through authorized Microchip distributors globally, with distributor stock often available for shorter lead times depending on quantity.
