PIC16CE625-20/P Visão geral
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory (ROM/OTP/Flash), data memory (RAM), and peripherals on one die; OTP-based variants are programmed once at production and cannot be re-written, making them cost-optimized for high-volume mature products. The PIC16CE625-20/P belongs to the mid-range PICmicro architecture family, which sits below PIC18 in performance but above baseline PIC10/12/14 devices in peripheral integration. EEPROM data memory provides non-volatile byte-level storage separate from program memory, allowing user parameters to persist across power cycles without external NVRAM.
Key features include 13 digital I/O pins, two analog comparators with programmable on-chip voltage reference, a capture/compare/PWM (CCP) module, an 8-bit timer/counter (TMR0) with 8-bit prescaler, a 16-bit timer/counter (TMR1), and a Watchdog Timer with its own on-chip RC oscillator for reliable operation. Brown-out Reset and Power-on Reset provide robust power supervision, while the wide 2.5V to 5.5V operating range covers both 3.3V and 5V system rails.
Typical applications for the PIC16CE625-20/P span consumer appliances, simple motor control, sensor signal conditioning, battery chargers, and remote-control transmitters where low cost, deterministic instruction execution, and small code footprint matter more than raw computational throughput.
When designing with this device, ensure the supply decoupling capacitor is placed within 5 mm of the VDD pin and that MCLR is tied through a 10 kohm pull-up to VDD for proper reset behavior.

Aplicações típicas
PIC16CE625-20/P é adequado para 6 aplicaçãos: Consumer Appliance Control, Remote Control Transmitters, Battery Chargers, Sensor Signal Conditioning, Small Motor and Solenoid Control, LED Lighting and Signage Controllers.
Consumer Appliance Control
The PIC16CE625-20/P is well-suited for consumer appliance control boards including washing machines, microwave ovens, and rice cookers where its 3.5 KB OTP program memory holds appliance-specific control firmware, the 13 I/O pins drive relay coils and indicator LEDs, and the wide 2.5-5.5 V supply tolerates rectified mains-derived rails. The two on-chip analog comparators monitor sensor inputs such as temperature thermistors or water-level probes without external op-amps, while the Watchdog Timer with dedicated RC oscillator prevents firmware lockup in unattended kitchen environments. With only 35 instructions and 200 ns deterministic execution, real-time control loops for motor speeds, heater duty cycles, and user-interface button debouncing fit comfortably. The 18-PDIP package supports hand-soldered prototyping as well as automated through-hole assembly on legacy manufacturing lines.
Recomendado
Remote Control Transmitters
For IR/RF remote control transmitters, the PIC16CE625-20/P delivers the deterministic 200 ns instruction execution needed to generate precise 38 kHz carrier waveforms for RC5, NEC, or proprietary protocols without jitter. The 128-byte EEPROM stores pairing codes, channel IDs, and learned-button mappings that persist across battery swaps, while the 2.5-5.5 V operating range covers single-cell lithium coin-cell batteries and 3 V CR2032 cells typical in handheld remotes. Sleep current in the microamp range extends battery life to multiple years, and the 35-instruction RISC core minimizes code size so simple modulation routines fit within the 3.5 KB OTP. The 13 I/O pins interface to the keypad matrix, IR LED driver, and status indicator LED directly, eliminating external glue logic.
Recomendado
Battery Chargers
The PIC16CE625-20/P controls NiCd, NiMH, and small lithium-ion charger topologies by sampling battery voltage through its two on-chip analog comparators and switching the charge current via PWM from the CCP module. The 128-byte EEPROM retains charge-cycle counters, battery chemistry profiles, and user preferences across power cycles, while the 8-bit TMR0 and 16-bit TMR1 deliver accurate timing for -delta-V and timer-based charge termination. With 2.5-5.5 V operation, the device runs directly from a 5 V USB rail or a rectified wall adapter, and the Brown-out Reset prevents erroneous charging during undervoltage conditions. Its compact 18-PDIP footprint drops into charger PCBs alongside discretes for a low-BOM, OTP-secure firmware solution that prevents field tampering.
Recomendado
Sensor Signal Conditioning
Industrial and HVAC sensor front-ends benefit from the PIC16CE625-20/P's dual analog comparators with programmable voltage reference, which threshold-detect thermocouple, thermistor, and 4-20 mA loop signals without external op-amps. The 20 MHz clock runs linearization lookup tables and digital filtering algorithms in real time, while the 128-byte EEPROM stores calibration coefficients unique to each sensor module. The wide 2.5-5.5 V supply range supports 3.3 V and 5 V sensor nodes, and the 18-PDIP package fits legacy through-hole industrial backplanes. Brown-out Reset and Watchdog Timer ensure the MCU recovers from brown-outs and firmware hangs common in electrically noisy factory environments.
Recomendado
Small Motor and Solenoid Control
Brushed DC motors, stepper motors, and solenoid valves are controlled by the PIC16CE625-20/P using its CCP module to generate variable-duty PWM up to 20 kHz while TMR1 measures back-EMF and stall currents. The 13 I/O pins drive H-bridge gate signals, direction logic, and end-stop sensors, while the dual analog comparators implement current-limit protection. OTP program memory locks in motor-control firmware to prevent field modification, and the deterministic 200 ns cycle time keeps commutation jitter under tight bounds. The 18-PDIP package is well-suited to through-hole motor driver boards, and the 2.5-5.5 V supply covers battery-powered and 24 V industrial bus applications.
Recomendado
LED Lighting and Signage Controllers
RGB LED strips, channel-letter signs, and decorative lighting use the PIC16CE625-20/P to generate multi-channel PWM for color mixing, dimming, and chase effects. The CCP module plus software PWM on TMR0 deliver up to 10-bit dimming resolution across the 13 I/O pins, while the 128-byte EEPROM stores scene presets, brightness levels, and animation sequences that survive power cycling. The wide 2.5-5.5 V supply range accepts 5 V and 12 V LED rails, and the 18-PDIP package fits traditional through-hole lighting control PCBs. Brown-out Reset prevents flicker during voltage sags, and the 35-instruction RISC core keeps color-cycle code compact within the 3.5 KB OTP budget.

Notas de projeto
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 14) with a ground return to VSS (pin 5) within 5 mm. For designs with high-current peripherals or noisy relay loads, add a bulk 10 uF tantalum or low-ESR ceramic on the same supply rail. The PIC16CE625-20/P draws roughly 2 mA active at 4 MHz and below 2 uA in sleep mode, so decoupling must keep rail ripple under 50 mVpp to avoid spurious Brown-out Resets across the 2.5-5.5 V operating range.
Route the MCLR pin (pin 4) directly to a 10 kohm pull-up resistor tied to VDD, with a 100 nF capacitor to ground for noise immunity. Keep the oscillator traces (OSC1 pin 16, OSC2 pin 15) short and surrounded by a ground pour to prevent EMI pickup; for crystal operation, place the crystal within 10 mm of the OSC pins with load capacitors sized per the crystal manufacturer datasheet. Avoid routing digital switching signals (relay drivers, PWM outputs) under or near the oscillator traces to minimize clock jitter.
Do not exceed 5.5 V on VDD; the device is not 5 V tolerant above this absolute maximum and will suffer permanent damage. Watchdog Timer postscaler must be configured correctly - a Watchdog timeout shorter than the longest legitimate loop will reset the MCU in normal operation. The PIC16CE625-20/P is OTP (one-time-programmable), so verify code thoroughly with MPLAB X IDE and emulator/debugger tools before programming production units, as the part cannot be erased or rewritten once programmed.
Long PCB traces on RB0-RB7 (pins 6-13) can pick up noise and trigger false interrupts; use series resistors or buffer external signals when running long cables. The CCP1 pin must be assigned explicitly via the APFCON or PPS-equivalent register on related parts to avoid PWM being routed to an unintended I/O. For designs using the analog comparators, dedicate RA0-RA3 (pins 17, 18, 1, 2) to analog functions and disable digital input buffers on those pins to prevent digital switching noise from corrupting threshold comparisons.
Informações de conformidade
RoHS, REACH, lead-free, and halogen-free status were not stated in the verified distributor listings or Microchip product page snapshot. Legacy through-hole PIC16CE62X parts typically predate universal RoHS documentation; verify compliance directly with Microchip for production use.
