What are the key features of PIC16F628-20/SO?
- Up to 20 MHz clock speed with internal 4 MHz oscillator, reducing external component count for compact designs
- Dual analog comparators with programmable voltage reference for signal conditioning without external op-amps
- 2 KB Flash and 224 bytes RAM in an 18-pin SOIC-18 package for low-cost, small-footprint embedded control
What is PIC16F628-20/SO used for?
PIC16F628-20/SO suits simple embedded control tasks such as motor speed control, sensor interfacing, and appliance management where an ADC is not required. Its dual comparators and timer modules enable PWM generation and event timing directly on-chip, reducing BOM cost in high-volume consumer products. The SOIC-18 package enables compact PCB layouts for space-constrained designs in white goods and industrial automation.

Frequently Asked Questions
Does PIC16F628-20/SO include an ADC, and what analog features does it provide instead?
PIC16F628-20/SO does not include an ADC. Instead, it provides 2 analog comparators with a programmable on-chip voltage reference, which can be used to compare input signals against a threshold. This makes it suitable for zero-crossing detection, over-voltage sensing, and simple analog threshold monitoring without an external comparator IC.
Which timer and PWM capabilities does PIC16F628-20/SO offer for motor and lighting control?
The PIC16F628-20/SO includes three timer modules—Timer0, Timer1, and Timer2—and a Capture/Compare/PWM (CCP) module that generates PWM signals up to 20 MHz clock derived frequency. The CCP module supports 10-bit PWM resolution, making it suitable for DC motor speed control, LED dimming, and servo positioning in embedded designs running on a 2 V to 5.5 V supply.
How does PIC16F628-20/SO compare with PIC16F628A for a new 18-pin SOIC design?
The PIC16F628A is the direct successor to the PIC16F628-20/SO and offers the same 2 KB Flash, 224 bytes RAM, and 18-pin SOIC-18 footprint, but at an extended clock up to 20 MHz with improved low-voltage programming. For new designs, Microchip recommends the PIC16F628A. However, PIC16F628-20/SO remains available for legacy board replacements and repair, with identical pinouts and peripheral compatibility.
