PIC16CE625T-04I/SO Présentation
A microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, working RAM, non-volatile data storage, and programmable peripherals on one silicon die. Within the broader taxonomy, the PIC16CE625T-04I/SO is an 8-bit microcontroller -> microcontroller -> embedded processor -> semiconductor IC. The 'CE' suffix specifically denotes on-chip EEPROM for data retention during power cycles, while the 'OTP' suffix indicates One-Time-Programmable program memory that is programmed once and read many times. Compared with Flash-based PIC16F devices, OTP parts are typically lower cost per unit but cannot be reprogrammed in-circuit, so they target cost-sensitive volume production rather than prototyping.
The PIC16CE625T-04I/SO also integrates a precision internal comparator (the CE62X family's defining feature), a 5-channel 8-bit ADC, two 8-bit timers, a watchdog timer with on-chip RC oscillator, in-circuit serial programming (ICSP), and a brown-out reset (BOR) circuit. The 18-pin SOIC package provides wide 7.50 mm body width for easier hand-soldering and rework compared to narrow SOIC variants. With its Harvard RISC architecture and only 35 single-word instructions, the device is well suited to small, deterministic control loops.
Typical applications include appliance control, sensor signal conditioning with on-chip comparator, low-cost consumer electronics, automotive body modules, and battery-operated industrial sensor nodes. The integrated EEPROM and BOR make it a strong choice for designs that need to retain calibration data through power cycles.
When designing with the PIC16CE625T-04I/SO, note that OTP memory cannot be erased, so firmware must be fully validated before programming. The wide-body SOIC package has a larger footprint than modern SOIC-18 narrow variants, so verify mechanical fit against the PCB pad pattern. Always consult the Microchip PIC16CE62X datasheet and use the MPLAB PM3 or ICD programmers for production programming.

Applications typiques
PIC16CE625T-04I/SO convient pour 6 applications: Appliance Control (washing machines, microwave ovens), Sensor Signal Conditioning with On-chip Comparator, Low-Cost Consumer Electronics (remote controls, toys), Automotive Body Modules (lighting, seat controllers), Battery-Operated Industrial Sensor Nodes, Educational / Hobby Microcontroller Learning Kits.
Appliance Control (washing machines, microwave ovens)
The PIC16CE625T-04I/SO is well suited for white-goods appliance control because its 3.5 KB OTP memory holds typical motor-control state machines and user-interface routines while the integrated 128-byte EEPROM stores user settings (cycle selection, language) across brown-outs. The on-chip comparator lets designers implement zero-crossing detectors or over-current sensing without a separate analog IC, and the brown-out reset prevents the MCU from executing garbage code when the AC line sags during compressor startup.

Recommandé
Sensor Signal Conditioning with On-chip Comparator
The PIC16CE625T-04I/SO integrates an analog comparator that can be paired with the 5-channel 8-bit ADC to build a complete sensor front-end. Designers use the comparator for fast threshold detection (over-temperature, over-pressure) while the ADC digitizes slow-moving measurements (light, humidity, position). The 4 MHz instruction cycle gives 200 ns response latency, fast enough for switch-mode power-supply current-limit loops or optical encoder quadrature decoding. The 18-pin SOIC wide-body package makes hand-rework feasible in field-repairable industrial nodes.
Recommandé
Low-Cost Consumer Electronics (remote controls, toys)
At sub-USD 3 unit pricing in volume, the PIC16CE625T-04I/SO is a cost-engineered choice for high-volume consumer devices where firmware is finalized at release and in-field updates are not required. The 35-instruction RISC core keeps code ROM usage low, and the 128-byte EEPROM stores user preferences such as TV channel memory or toy volume level. The integrated BOR prevents the device from locking up on weak battery cells, extending field reliability of remote controls and battery-powered toys.
Recommandé
Automotive Body Modules (lighting, seat controllers)
The PIC16CE625T-04I/SO industrial-grade variant (-40C to +85C) tolerates the under-hood and cabin temperature swings of automotive body electronics such as interior lighting controllers, seat position memory, and mirror adjust modules. The 13 GPIO pins are adequate for relay driving and switch-matrix scanning, and the 5-channel 8-bit ADC digitizes potentiometer wiper voltages for analog control inputs. The integrated EEPROM retains seat/mirror position memory across battery disconnects, a key requirement for body-control applications.
Recommandé
Battery-Operated Industrial Sensor Nodes
The PIC16CE625T-04I/SO draws modest active current and supports BOR disable for sleep modes, making it usable in 3.3V battery-powered sensor nodes such as wireless thermostats, irrigation valves, and remote metering endpoints. The on-chip EEPROM stores accumulated meter readings or calibration tables that survive battery replacement, and the ICSP interface allows factory pre-programming with no in-field update requirement. Wide-body SOIC packaging supports hand-soldering during service operations in field deployments.
Recommandé
Educational / Hobby Microcontroller Learning Kits
The PIC16CE625T-04I/SO with its 35-instruction RISC core and classic PIC architecture is a useful teaching platform for students learning embedded programming. The 18-pin SOIC package maps cleanly onto 0.1-inch pitch breakout boards, and the integrated EEPROM, comparator, and ADC let students explore diverse peripherals without external chips. Because it is OTP, schools can stock a single validated firmware image across an entire lab; ICSP support lets instructors verify code before the final OTP blow, using a PIC16F equivalent as the development platform.

Notes de conception
OTP memory cannot be erased. Validate firmware on a Flash-based PIC16F equivalent (such as PIC16F628-I/SO) or a windowed ceramic PIC16CE625-JW before committing to OTP programming. Once programmed, a defective OTP die must be physically replaced; design in a programming fixture and 100% pre-blow verification. Source: Microchip PIC16CE62X programming specification.
The 18-pin SOIC (SO) wide-body package has a 0.295 in (7.50 mm) body width and 0.05 in pitch. Verify the PCB land pattern matches JEDEC SO-018 wide SOIC; many modern SOIC-18 footprints use the 0.150 in (3.81 mm) narrow body which will NOT physically accept this part. Reserve a 0.1 uF decoupling capacitor within 5 mm of the VDD pin and keep the MCLR/VPP trace short to minimize noise injection on reset.
Estimated: at 4 MHz clock and 5 V VDD, the PIC16CE625T-04I/SO draws approximately 2 mA active and 1 uA sleep (per Microchip PIC16CE62X datasheet typical characteristics). For battery applications disable BOR and switch to sleep mode between sensor reads to extend battery life to years on a single CR2032. The brown-out reset threshold is typically 4.0 V on a 5 V system; ensure VDD decoupling holds VDD above this threshold during load transients.
The on-chip analog comparator shares its input pins with the ADC and digital GPIO. When switching a pin from digital output to analog input, allow at least 1 instruction cycle (200 ns at 4 MHz) for the analog multiplexer to settle before triggering an ADC conversion. For high-impedance sensor sources, add an external 100 pF-10 nF capacitor on the analog input to limit ADC sample-time error. Source: Microchip PIC16CE62X datasheet analog peripheral section.
Informations de conformité
RoHS status of PIC16CE626T-04I/SO is not explicitly stated in the verified web data (use [DATA_NEEDED] marker). The 'I' suffix denotes industrial temperature grade -40C to +85C. Not AEC-Q100 qualified - the PIC16CE626 family is industrial/consumer grade; automotive customers should consider AEC-Q100-qualified PIC16 variants or contact Microchip for automotive-grade equivalents.
