PIC16C622-04/SS 概要
What is an 8-bit OTP microcontroller? An 8-bit microcontroller is a small computer-on-a-chip built around an 8-bit data path and a RISC instruction set, optimized for deterministic real-time control. The OTP (one-time-programmable) variant uses EPROM program memory that can be written once during production and cannot be erased, lowering die cost versus flash parts. Within Microchip's portfolio, the PIC16C62x family belongs to the PIC16 mid-range architecture, sits between the baseline PIC10/12/16 families and the enhanced PIC18 family, and is part of the broader microcontroller (MCU) -> embedded IC -> semiconductor taxonomy.
Key features include a 14-bit instruction word, hardware USART, capture/compare/PWM module, two 8-bit timers plus one 16-bit timer, a 5-channel 8-bit ADC, and an internal watchdog timer. Low-power consumption is rated at 15 µA typical at 5V / 4 MHz and 1 µA typical at 3V / 32 kHz, allowing battery-friendly standby operation. The device is fully static and supports DC to 4 MHz operation across commercial, industrial, and extended temperature ranges.
The PIC16C622-04/SS uses Microchip's mid-range RISC core with a hardware multiplier-free architecture, dual clock domains, and on-chip oscillator options for RC, LP, XT, and HS modes. The '04' speed suffix denotes a 4 MHz maximum oscillator frequency, while the 'I' industrial temperature variant covers -40C to +85C.
Typical applications include small appliance controls, sensor signal conditioning, IR remote receivers, simple motor drivers, and low-cost consumer electronics. Industrial uses span HVAC damper controls, security keypads, and metering front-ends where deterministic interrupt response and small form factor matter.
When designing with this part, remember OTP memory cannot be re-programmed in-circuit - prototype firmware must be validated on a windowed PIC16C622 JW or a flash-equivalent PIC16F628 before committing to OTP. Use decoupling capacitors of 0.1 µF ceramic on VDD and place the ICSP clock/data pins away from high-current traces.

主な用途
PIC16C622-04/SS の用途: 6 件s: Small Appliance Control, IR Remote Receiver Decoders, Industrial Sensor Signal Conditioning, Low-Cost Consumer Electronics Toys, HVAC Damper and Valve Controllers, Security Keypads and Access Panels.
Small Appliance Control
The PIC16C622-04/SS is well suited for small appliance control because its 3.5 KB OTP program memory fits typical washing-machine, coffee-maker, or microwave firmware. The 5-channel 8-bit ADC reads temperature, water level, and potentiometer inputs; the 4 MHz CPU handles real-time switching logic, while the USART supports diagnostic links. Low 15 µA typical active current enables energy-efficient standby. Place decoupling 0.1 µF ceramic capacitors on VDD and keep MCLR pull-up resistor within 10 kΩ of the pin.
おすすめ
IR Remote Receiver Decoders
The PIC16C622-04/SS handles consumer IR remote decoding with its 16-bit timer capturing the edge timing of 38 kHz carrier bursts from TV/AV remote protocols (Philips RC5/RC6, NEC, Sony SIRC). The 14-bit instruction word and 4 MHz clock resolve sub-bit timing accurately, while the CCP module generates carrier waveforms for transmitter reference circuits. The 3.5 KB OTP fits standard protocol libraries for set-top boxes, fans, and lighting. Operate at 5V for noise immunity in IR photodiode front-end designs.
おすすめ
Industrial Sensor Signal Conditioning
The PIC16C622-04/SS excels in industrial 4-20 mA loop transmitter and bridge-sensor signal conditioning where its 5-channel 8-bit ADC digitizes pressure, flow, and strain-gauge outputs. The integrated watchdog timer (WDT) provides failsafe recovery from ESD-induced lockups on the factory floor, while hardware USART feeds digital readings to PLCs or HMIs. Industrial temperature variant PIC16C622-04I/SS extends operating range to -40C to +85C. Use 2.5V to 5.5V supply with brown-out reset enabled for robust industrial deployment.
おすすめ
Low-Cost Consumer Electronics Toys
The PIC16C622-04/SS is widely adopted in low-cost educational toys, electronic dice, and LED-driven gadgets where the 3.5 KB OTP and 128 B RAM cover simple state machines. Its 13 I/O pins drive RGB LEDs, audio buzzers, and small DC motor H-bridges, with the CCP module generating PWM for servo control. Commercial 0C to +70C temperature suits indoor toys, while the OTP die-cost advantage keeps retail unit cost below $2. Pair with an NPN transistor array to drive higher-current loads.
おすすめ
HVAC Damper and Valve Controllers
Building HVAC damper and valve actuators use the PIC16C622-04/SS for closed-loop position control where its 16-bit timer captures tachometer feedback and the CCP module drives servo valves. The 5-channel ADC reads thermistor, humidity, and potentiometer-setpoint signals, while the hardware USART links to BACnet/Modbus gateways. Brown-out reset and watchdog timer protect against brown-out and EMI-induced faults on long motor wiring runs in commercial buildings.
おすすめ
Security Keypads and Access Panels
Security keypads and PIN-entry access panels use the PIC16C622-04/SS for matrix keypad scanning via 13 I/O pins (3×4 matrix) and Wiegand/clock-data output through the hardware USART. The 3.5 KB OTP stores PIN hashing routines, while EEPROM emulation uses program memory wear-leveling (note: PIC16C622 lacks true EEPROM - design uses software emulation). Industrial temperature variant supports outdoor installations. Add TVS protection on keypad lines for ESD compliance.

設計ノート
OTP memory cannot be erased or rewritten once programmed. Always validate firmware on a windowed PIC16C622 JW (ceramic window) or flash-equivalent PIC16F628-04I/SS before committing to OTP production. Once blown, defective units must be physically replaced, not re-flashed - factor in scrap allowance during production ramp-up. Code-protect bits, once set, prevent verification of EPROM contents and block all further programming attempts.
Place a 0.1 µF decoupling capacitor within 5 mm of the VDD pin (pin 20) with a short trace to the ground plane. For SSOP packages, use a via-in-pad or stitched ground plane directly under the exposed die attach area. Add a bulk 10 µF tantalum or aluminum polymer capacitor on the supply rail to handle CCP and ADC transient loads. The MCLR pin (pin 1) requires a 10 kΩ pull-up to VDD for normal operation; do not leave it floating during in-circuit programming.
Keep the OSC1/OSC2 traces short and symmetric for crystal mode (XT, HS). For 4 MHz operation, XT mode is preferred over HS to minimize EMI and power consumption. Place the crystal within 5 mm of pins 9 and 10, with a ground guard ring on both sides. Avoid routing high-current switching traces (CCP PWM outputs) parallel to the oscillator traces to prevent beat-frequency interference into ADC readings.
The PIC16C622-04/SS draws 15 µA typical at 5V / 4 MHz active and 1 µA typical at 3V / 32 kHz standby. Brown-out reset (BOR) should be enabled in the configuration word to reset the MCU when VDD falls below the BOR threshold (~4.0V), preventing code execution from corrupted EPROM reads. For battery applications, use sleep mode aggressively and wake via WDT timeout.
コンプライアンス情報
PIC16C622-04/SS SSOP variant is non-RoHS (lead-based finish). Industrial temperature variants (PIC16C622-04I/SS) are also non-RoHS. RoHS-compliant designs should select the PIC16F628-04I/SS flash equivalent. Per Microchip product declarations, all listed parts are REACH-compliant and halogen-free.
