PIC16CE625T-30/SO Overview
An 8-bit microcontroller (MCU) is a single-chip computer that combines a CPU, program memory (ROM/Flash/OTP), working RAM, and peripherals (timers, ADC, comparators, I/O) on one die. The PIC16CE62X family belongs to the PIC16 mid-range architecture and sits inside the broader hierarchy: MCU -> microcontroller -> embedded processor -> semiconductor. The unique value of the PIC16CE62X line is the addition of on-chip serial EEPROM data memory alongside OTP program memory, letting designers store calibration data, configuration settings, and runtime parameters without an external EEPROM chip.
Key features of the PIC16CE625 include 13 digital I/O pins, a precision analog comparator, one 8-bit timer/counter and one 16-bit timer/counter (Timer0/Timer1), a watchdog timer with dedicated on-chip RC oscillator, and an internal 4 MHz RC oscillator that can be software-configured to 30 MHz. The integrated EEPROM typically provides 128 bytes of non-volatile data storage, while the OTP program memory holds the application firmware. Power-saving features include SLEEP mode, programmable brown-out reset (BOR), and a wide operating voltage range of 2.5 V to 6.0 V.
Architecturally, the PIC16CE625 uses a Harvard RISC core with separate program and data buses, 35 single-word instructions, and a 14-bit instruction word. The CMOS process delivers low operating current and industrial temperature range support (-40C to +85C for the E suffix; 0C to +70C for the standard part), enabling deployment in noisy electrical environments.
Typical applications include low-cost consumer electronics, remote-control transmitters, sensor signal-conditioning front-ends with on-board calibration storage, small motor control, security keypads, and battery-powered devices. The integrated comparator allows threshold detection and battery-voltage monitoring without external analog components. Design with the in-circuit serial programming (ICSP) interface for OTP programming in production; OTP memory cannot be electrically erased, so a one-time-programmed device is the final form. Designers who require reprogrammability during prototyping should evaluate PIC16F62X flash variants as an alternative.

Typical Applications
PIC16CE625T-30/SO is suitable for 6 applications: Remote Control Transmitter, Sensor Signal Conditioning Front-End, Security Keypad Controller, Battery-Powered IoT Edge Node, Small DC Motor and Solenoid Controller, Consumer Appliance Timer / Sequencer.
Remote Control Transmitter
The PIC16CE625T-30/SO suits low-cost IR/RF remote-control transmitters where the PIC's 30 MHz core runs Manchester or pulse-position-modulated encoding fast enough to handle 8-bit button matrices. With 13 I/O pins the device scans a 4x4 or 5x3 key matrix directly, while the 128-byte on-chip EEPROM stores pairing codes and learn-mode configuration without an external memory chip. SLEEP mode draws single-digit microamp currents between button presses, enabling coin-cell battery life measured in years. The integrated analog comparator on pins CIN+/CIN- can detect low-battery conditions on a divided supply rail. The 30 MHz instruction cycle is ample for generating 38 kHz carrier signals typical of consumer IR protocols.
Recommended
Sensor Signal Conditioning Front-End
Use the PIC16CE625T-30/SO as a sensor front-end that reads an analog signal, digitizes thresholds using the on-chip analog comparator, and stores calibration constants in the integrated 128-byte EEPROM. The on-chip comparator eliminates external op-amps for threshold detection of thermistor, photodiode, or Hall-sensor outputs. The 30 MHz core runs linearization math (Steinhart-Hart, look-up tables) in under 100 microseconds, well within the bandwidth of industrial sensor sampling. EEPROM endurance of 1M write cycles is sufficient for periodic in-field recalibration. The 2.5 V to 6.0 V supply range lets the device run directly from a 3.3 V or 5 V sensor rail. Brown-out reset prevents erroneous calibration writes during power-down.
Recommended
Security Keypad Controller
The PIC16CE625T-30/SO is well matched to security keypads and access-control pads where 12-13 I/O pins drive a 3x4 or 4x4 matrix scan and the 128-byte EEPROM stores encrypted PINs, user credentials, and audit logs. The 35-instruction PIC16 RISC core executes PIN hashing and comparison in microseconds, making brute-force timing attacks computationally expensive. The integrated watchdog timer resets the device if firmware locks up, a critical reliability feature for unattended security hardware. Brown-out reset prevents EEPROM corruption during power glitches. SLEEP mode minimizes idle current between key presses for battery-backed panels. ICSP allows the OEM to load final firmware after the keypad has been assembled.
Recommended
Battery-Powered IoT Edge Node
Deploy the PIC16CE625T-30/SO as a duty-cycled edge sensor node for IoT applications where SLEEP current is the dominant power budget item. The PIC16 mid-range core in SLEEP mode draws single-digit microamps, and the 30 MHz maximum clock lets the device wake, sample sensors, run decision logic, transmit via UART-linked radio, and return to SLEEP in a few milliseconds. The 128-byte on-chip EEPROM stores device IDs, security tokens, and last-known-state data without external memory. The 2.5 V to 6.0 V supply range accepts 3.6 V lithium-thionyl-chloride cells directly. The 0C to +70C commercial temperature range suits indoor and sheltered deployments; choose the industrial 'I' suffix for outdoor nodes.
Recommended
Small DC Motor and Solenoid Controller
Use the PIC16CE625T-30/SO as a low-cost H-bridge driver controller for small DC motors, solenoids, and relays. The 13 I/O pins drive four half-bridge channels (8 pins) plus enable, fault, and feedback signals. The 16-bit Timer1 generates PWM frequencies up to 250 kHz with software-controlled duty cycle, providing speed and torque control for brushed DC motors. The 30 MHz core handles back-EMF sensing via the analog comparator and adjusts PWM in real time for soft-start and current limiting. Brown-out reset prevents coil flyback damage during power-down. OTP memory suits the fixed-parameter nature of appliance-class motor controllers.
Recommended
Consumer Appliance Timer / Sequencer
The PIC16CE625T-30/SO is an excellent fit for washing-machine timers, dishwasher sequencers, coffee-machine controllers, and similar appliances that need a deterministic state machine with stored user preferences. The 3.5 KB OTP holds a full state-machine program; the 128-byte EEPROM retains user settings, cycle counters, and last-cycle state across power outages. Timer0 (8-bit) and Timer1 (16-bit) generate precise wash-cycle, rinse, and spin durations in hardware without firmware intervention. The on-chip analog comparator monitors supply voltage and water-level sensor inputs. Watchdog timer prevents the appliance from hanging mid-cycle. The 30 MHz clock gives sub-microsecond response to operator button interrupts.

Key Differentiators
- Integrated EEPROM data memory eliminates external memory chip (vs PIC16F84A)
- 30 MHz internal oscillator enables higher throughput (vs PIC16CE625-04/SO)
- OTP one-time-programmable cost advantage over Flash (vs PIC16F625-I/SO)
- Wide 2.5 V to 6.0 V supply supports 3 V and 5 V rails (vs PIC16F628A-I/SO)
Design Notes
OTP memory is one-time-programmable - any code change after programming requires a new device. Always complete full firmware validation on a PIC16F625 (Flash equivalent) development board before committing to a PIC16CE625T-30/SO production run. ICSP programming must be performed only once per device. Brown-out reset should be enabled in the configuration word to prevent EEPROM corruption during power-down events.
Place a 100 nF decoupling capacitor as close as possible to the VDD pin (pin 14) and a bulk capacitor (1 uF to 10 uF) on the same supply trace. Keep the crystal/oscillator traces short and surrounded by a ground guard ring to minimize clock noise coupling into analog comparator inputs. The MCLR pin (pin 4) should be tied to VDD through a 10 kohm resistor; if not used, connect directly to VDD to avoid spurious resets.
At 30 MHz and 5 V supply the PIC16CE625T-30/SO draws approximately 5 mA active and drops to single-digit microamps in SLEEP mode. Estimated: using typical datasheet figures of 2 mA at 4 MHz scaled linearly, 30 MHz active current at 5 V is roughly 5 mA. For battery applications, duty-cycle aggressively - spend 99% of the time in SLEEP and wake only for sensor sampling and radio transmission windows.
When using the analog comparator, route the CIN+ and CIN- traces symmetrically and keep them away from the OSC1/OSC2 clock traces to prevent noise injection. The comparator output can be routed to Timer1 gate for capture, allowing precise timing measurements of analog events. Use the CVREF output as the comparator reference for absolute threshold detection of supply voltage or sensor signals.
Compliance Information
Compliance status not stated in verified web data. RoHS, REACH, lead-free, and halogen-free status should be confirmed by requesting the latest Material Declaration from Microchip. The PIC16CE62X family predates the most recent RoHS recasts; many lot-traceable variants are RoHS-compliant but the original 30 MHz grade may carry lead-based finish depending on date code.
