What are the key features of PIC16C622A-04/SS?
- 4 MHz 8-bit PIC16C EPROM core with 2 KB program memory provides a UV-erasable, reprogrammable option for low-volume production and prototyping before committing to OTP
- Integrated analogue comparators enable direct voltage threshold detection and analogue signal comparison without external op-amp or comparator ICs
- Compact SSOP-20 SMD footprint with 18 available I/O pins suits space-constrained PCB designs requiring digital I/O switching and comparator-based analogue sensing
What is PIC16C622A-04/SS used for?
The PIC16C622A-04/SS targets simple analogue and digital control tasks in consumer electronics and industrial equipment where voltage comparison and timed I/O switching are the primary functions, and no ADC conversion is required. Typical uses include over-voltage protection logic, fan speed comparator controls, power sequencing circuits, and LED driving applications where the integrated comparators replace discrete op-amp circuitry. Its SSOP-20 SMD form factor and 4 MHz operation make it a low-cost, compact option for medium-volume products with well-defined control requirements.

Frequently Asked Questions
Does the PIC16C622A-04/SS include an ADC, and what analogue capability does it provide instead?
The PIC16C622A-04/SS does not include an analogue-to-digital converter. Instead it provides 2 integrated analogue comparators that compare two input voltages and output a digital high or low signal, enabling threshold detection, zero-crossing detection, and window comparator circuits without any external analogue ICs.
What is the maximum clock frequency of the PIC16C622A-04/SS, and how does this translate to instruction throughput?
The PIC16C622A-04/SS runs at a maximum clock frequency of 4 MHz. The PIC16 architecture executes most instructions in 4 clock cycles, giving a peak instruction throughput of 1 MIPS (1 million instructions per second). This is adequate for simple control loops with sub-millisecond response times in thermostat or motor control applications.
How does the EPROM memory of the PIC16C622A-04/SS compare to OTP variants in a development versus production workflow?
EPROM variants such as the PIC16C622A-04/SS can be erased using a UV light source (typically 15 to 25 minutes at 254 nm wavelength) and reprogrammed multiple times, making them ideal for firmware development and small-batch production. OTP variants are cheaper for high-volume manufacturing but cannot be erased; engineers typically prototype with the EPROM windowed package and switch to OTP only when the code is fully validated.
How many I/O pins does the PIC16C622A-04/SS provide in its SSOP-20 package, and are any pins multiplexed with comparator functions?
The PIC16C622A-04/SS provides 18 I/O pins in the SSOP-20 package. Several of these pins are multiplexed with the 2 analogue comparator inputs (CIN+ and CIN- channels), meaning those specific pins cannot simultaneously serve as general-purpose digital I/O when the comparators are enabled, reducing the available GPIO count by up to 4 pins depending on comparator configuration.
