Frequently Asked Questions
What are the core specifications of the PIC16F628-04/SO microcontroller?
The PIC16F628-04/SO is an 8-bit microcontroller based on the PIC16 CPU family with a maximum clock frequency of 4MHz. It does not include an ADC (Has ADC: NO) and does not support boundary scan testing. The device is housed in an 18-pin SOIC package and has been available since June 1999, making it a mature and well-documented platform for embedded control applications.
What package is used for the PIC16F628-04/SO?
The PIC16F628-04/SO uses an 18-pin SOIC (Small Outline Integrated Circuit) package, with the manufacturer package code SOIC-18. This surface-mount package offers a compact footprint with 1.27mm lead pitch, making it suitable for automated PCB assembly. The device is also available in DIP package variants for through-hole designs and prototyping on breadboards.
Does the PIC16F628-04/SO include analog-to-digital conversion capability?
No, the PIC16F628-04/SO does not include an analog-to-digital converter (ADC). This device is optimized for purely digital control applications such as I/O management, timer-based sequencing, USART serial communication, and comparator functions. For applications requiring ADC capability within the PIC16 family, Microchip offers alternative devices such as the PIC16F876A or PIC16F877A with integrated 10-bit ADC channels.
What is the expected product lifetime and availability of the PIC16F628-04/SO?
The PIC16F628-04/SO has a YTEOL (Years To End Of Life) value of 3, indicating it is approaching the end of its product lifecycle. Factory lead time is approximately 5 weeks, so designers should plan procurement accordingly. For new designs, Microchip recommends evaluating more modern PIC16 variants with extended lifecycle support. Legacy system maintenance applications may still source this device through authorized distributors worldwide.
