Key Features
- 8-bit PIC16 CPU core with up to 20 MHz clock frequency and 1.5 KB flash program memory for compact control firmware
- Dual analog comparators enable direct voltage comparison without external components in SOIC-18 low-cost package
- No ADC design intentionally reduces cost and power for purely digital or comparator-based embedded control applications
Applications
The PIC16F627A-I/SO is suited for simple embedded control tasks such as relay sequencing, LED control, UART communication, and comparator-based threshold detection in home appliances and industrial timers. Its 1.5 KB flash and 20 MHz operation cover a wide range of low-complexity firmware applications without the cost premium of devices with unused ADC peripherals. The SOIC-18 package is widely supported for both prototyping and volume production on standard PCB assembly lines.

Frequently Asked Questions
What is the maximum clock frequency of PIC16F627A-I/SO, and how much flash program memory does it include?
The PIC16F627A-I/SO operates at up to 20 MHz and includes 1.5 KB of flash program memory, supporting approximately 1024 14-bit instructions. This combination is sufficient for UART communication, timer-based control loops, and comparator threshold detection in low-cost 8-bit embedded control applications packaged in an 18-pin SOIC.
Which simple control system designs are best matched to PIC16F627A-I/SO given it has no ADC but includes comparators?
Relay drivers, stepper motor sequencers, LED dimmer controllers, and over-voltage/under-voltage protection circuits are well-matched to PIC16F627A-I/SO because these applications require only digital I/O and threshold comparisons rather than full analog-to-digital conversion. The 2 on-chip comparators handle analog threshold detection at 20 MHz without needing an external comparator IC, reducing BOM cost.
When would PIC16F627A-I/SO be a more cost-effective choice than PIC16F877A for a simple timer relay project?
For a simple timer relay that requires only digital I/O, UART, and comparator threshold detection within 1.5 KB of code, PIC16F627A-I/SO is more cost-effective than PIC16F877A which has 8 KB flash, an 8-channel ADC, and an SSOP-40 package — all of which would go unused. Choosing the smaller 18-pin SOIC device reduces unit cost and PCB area while meeting the design requirements.
