- 20 MHz maximum clock speed with 3.5 KB OTP program memory for cost-sensitive embedded designs
- Dual analog comparators with programmable voltage reference for threshold detection without ADC
- Wide supply voltage range of 2 V to 5.5 V supporting both 3.3 V and 5 V system architectures
Applications
The PIC16C622A-20I/SS suits low-complexity embedded control tasks such as motor speed sensing, simple alarm detection, and appliance timing circuits where OTP one-time programmability reduces cost at volume. Its dual analog comparators allow direct threshold detection on sensor inputs, replacing discrete op-amp stages. Consumer electronics, power-supply supervisors, and battery management units frequently rely on this compact 8-bit MCU for deterministic low-latency responses.

Frequently Asked Questions
What program memory and RAM does the PIC16C622A-20I/SS offer for embedded firmware?
The PIC16C622A-20I/SS provides 3.5 KB of OTP (one-time programmable) Flash program memory and 128 bytes of on-chip RAM. Running at up to 20 MHz, the RISC architecture executes most instructions in a single 200 ns cycle, making it suitable for deterministic real-time control tasks such as PWM generation, switch debouncing, and simple communication protocols.
Does the PIC16C622A-20I/SS include analog peripherals and what comparator features does it have?
Yes, the PIC16C622A-20I/SS includes 2 on-chip analog comparators with a programmable voltage reference module offering 16 reference levels derived from the supply voltage. This eliminates the need for external op-amps in threshold-detection circuits, reducing BOM cost by at least 2 components. The comparator outputs can wake the CPU from sleep, enabling ultra-low-power event-driven operation.
What is the operating temperature range and supply voltage for the PIC16C622A-20I/SS industrial variant?
The 'I' suffix designates the industrial temperature range of -40°C to +85°C, suitable for harsh environments including outdoor enclosures and industrial machinery. The supply voltage range of 2 V to 5.5 V allows operation from coin cells, two AA batteries, or regulated 3.3 V and 5 V rails, giving designers flexibility across a wide range of power architectures.
When is PIC16C622A-20I/SS a practical alternative to newer flash-based PIC16 devices?
PIC16C622A-20I/SS is economical for high-volume products with frozen firmware, since OTP memory is cheaper than reprogrammable Flash at production scale. For designs with 13 I/O pins, 128 bytes RAM, and no ADC requirement, it avoids paying for unused peripherals present in larger devices. Its 20 MHz speed and mature toolchain compatibility with MPLAB IDE make it a drop-in replacement in legacy product lines needing long-term sourcing, often available with lead times of 11 weeks.
