PIC16CE625-04E/SO - 4MHz 8-bit MCU, 3.5KB OTP, 128B RAM | Microchip
MPN: PIC16CE625-04E/SO ✓ AktifPIC16CE625-04E/SO Ringkasan
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, and peripheral I/O into one device; an 8-bit MCU like the PIC16CE625 processes data in 8-bit chunks and is widely used in cost-sensitive embedded designs. Within the PIC16 family hierarchy, the CE62x sub-family is positioned as a low-cost EPROM/OTP member with on-chip EEPROM, sitting between the PIC16F flash parts and the JW windowed erasable variants. The PIC16CE625 specifically targets applications needing field-programmable, one-time-programmable parts with non-volatile data storage.
Key features include 35 single-word instructions, all single-cycle except program branches (200 ns at 20 MHz), a 14-bit instruction word, an 8-level hardware stack, two 8-bit timer/counters (Timer0, Timer2), one 16-bit timer/counter (Timer1), a 10-bit multi-channel ADC, an internal voltage reference, and a brown-out reset (BOR) circuit. The 'CE' suffix indicates integrated EEPROM (128 bytes), distinguishing it from the 'C' and 'F' siblings.
The architecture uses a Harvard RISC design with separate program and data buses, plus an internal RC oscillator option that eliminates external clock components in low-cost designs. The wide 3.0V to 5.5V operating range and -40C to +125C extended temperature grade ('E' suffix) suit automotive and industrial environments.
Typical applications include automotive sensor conditioning (with on-chip ADC + EEPROM storing calibration constants), industrial process-control loops, appliance control boards, security/PIR alarm panels, low-end motor drives, and remote-control transmitters where the integrated EEPROM retains user settings after power loss.
Designers should use Microchip's MPLAB XC8 compiler and either an ICD debugger or PICSTART+ programmer for development. The 18-pin SOIC footprint supports hand-soldering and rework, unlike smaller QFN packages, simplifying prototyping.

Aplikasi Umum
PIC16CE625-04E/SO cocok untuk 6 aplikasis: Automotive Sensor Signal Conditioning, Industrial Process-Control Loop, Appliance Control Board (HVAC / Washer / Dishwasher), PIR Alarm and Security Panel, Remote Control / RF Keyfob Transmitter, Brushless DC Fan / Small Motor Controller.
Automotive Sensor Signal Conditioning
The PIC16CE625-04E/SO is a strong fit for automotive sensor modules because its 10-bit ADC handles analog inputs from pressure, temperature, and position sensors while the 128-byte on-chip EEPROM stores factory calibration constants that persist across battery disconnects. Its -40C to +125C extended temperature grade meets under-hood and cabin AEC-Q100-style thermal stress, and the 4 MHz PIC16C core runs simple PID loops in 200 ns cycles - adequate for thermal-management solenoids and HVAC damper feedback. Designers place the MCU between the 12 V/5 V LDO regulator and the sensor bridge, with EEPROM written once during EOL calibration.

Industrial Process-Control Loop
In industrial 4-20 mA loop transmitters and PID valve controllers, the PIC16CE625-04E/SO offers the deterministic single-cycle instruction execution needed for tight control loops. Its 10-bit ADC samples process variables up to ~20 kS/s with internal reference, while Timer1 in 16-bit mode provides accurate time-base generation for PWM actuator drive. The wide 3.0V-5.5V supply tolerance handles noisy 24V-bus-derived rails, and the 128-byte EEPROM retains tuning parameters after field power cycling. For new designs the PIC16F628A is recommended for in-system firmware updates.

Appliance Control Board (HVAC / Washer / Dishwasher)
The PIC16CE625-04E/SO is well-suited for white-goods control boards that drive relays, triacs, and small brushless DC motors. Its 13 I/O pins connect directly to LED indicators, triac optocouplers, and zero-cross detectors, while the internal RC oscillator eliminates external crystals for cost reduction. The 128-byte EEPROM stores user-set wash cycles, spin speeds, and HVAC setpoints that survive power interruptions, and the brown-out reset prevents corrupted EEPROM writes during brown-outs. The integrated watchdog timer and extended temperature grade protect against fault conditions in harsh appliance environments.

PIR Alarm and Security Panel
PIR motion detectors and small security panels benefit from the PIC16CE625-04E/SO's low-power operation, on-chip ADC for ambient-light rejection, and 128-byte EEPROM for storing installer configuration (sensitivity, pulse count, walk-test mode). The integrated watchdog timer protects against firmware lockups, and the BOR circuit prevents false alarms from low-battery conditions in 3 V lithium-powered wireless PIR units. Pin-compatible PIC16F628A upgrades add flash memory for OTA-free firmware updates during development.

Remote Control / RF Keyfob Transmitter
Battery-powered RF keyfobs and remote controls leverage the PIC16CE625-04E/SO's 3.0V minimum supply to run directly from CR2032 coin cells. Its 200 ns instruction cycle easily generates 433/868 MHz sub-1 GHz OOK/FSK modulation patterns via Timer0 interrupts, and the 128-byte EEPROM stores rolling-code counters and paired-device IDs. The low-power PIC16C core and brown-out reset extend battery life and prevent lockups from weak cells; the 18-SOIC footprint supports compact keyfob PCBs.

Brushless DC Fan / Small Motor Controller
Small BLDC fans and DC motor controllers use the PIC16CE625-04E/SO's Timer2 PWM output to drive MOSFET gate drivers at variable duty cycles, with feedback from Hall sensors or back-EMF sampled by the 10-bit ADC. The 128-byte EEPROM stores calibrated RPM/speed curves and fault history. The wide 3.0V-5.5V supply tolerance handles 12 V fan rails stepped down to 5 V or 3.3 V, and the integrated brown-out reset protects motor windings from low-voltage stalls.

- Extended -40C to +125C temperature grade (vsPIC16CE625-04/SO)
- Largest program memory in PIC16CE62x 18-pin family (vsPIC16CE623-04/SO)
Catatan Desain
The PIC16CE625 is OTP (one-time-programmable) - there is no in-system reprogramming. A bug in production firmware requires device replacement. Use a PIC16F628A in the same 18-SOIC footprint for prototype development, then port the validated firmware to PIC16CE625 for production cost savings. Confirm MCLR/VPP pin 4 is pulled high through a 10 kohm resistor and bypassed with a 100 nF cap to VDD to prevent spurious resets during power-up.
Place the decoupling capacitor (100 nF X7R ceramic) within 5 mm of VDD pin 14, and add a bulk 10 uF tantalum or aluminum electrolytic cap at the regulator output. Keep the OSC1/OSC2 traces short (less than 10 mm) and surround them with a ground pour to minimize radiated EMI. The 18-SOIC land pattern supports hand-soldering and rework - unlike smaller QFN parts.
Estimated: at VDD=5V and full 4 MHz operation, the PIC16CE625 draws approximately 2-5 mA active and <1 uA sleep. For battery-powered designs, leverage the SLEEP instruction with watchdog-timer wakeup to drop average current below 10 uA. The brown-out reset (BOR) must be enabled in the configuration word to prevent EEPROM corruption during slow VDD ramp-up.
Informasi Konformitas
RoHS compliance, lead-free finish, and halogen-free status must be verified against the specific lot's manufacturer declaration of conformity (MDCF) on shipment. PIC16CE625 family predates universal RoHS adoption and Microchip shipped both lead-containing and lead-free variants; confirm by lot code or datasheet finishing designation. AEC-Q100 is not formally qualified for the 'E' grade, although the -40C to +125C range overlaps with AEC-Q100 Grade 1 limits.
