PIC16CE625T-04/SO - 8-bit 4MHz MCU, 3.5KB OTP, 18-SOIC | Microchip
MPN: PIC16CE625T-04/SO ✓ Hoạt độngPIC16CE625T-04/SO Tóm tắt
A PIC (Peripheral Interface Controller) microcontroller is a class of compact, RISC-based embedded processors designed for deterministic real-time control. The PIC16CE625 belongs to the PIC16C family of low-cost, high-performance CMOS, fully-static, 8-bit microcontrollers with integrated EEPROM data memory. Within the broader taxonomy it sits as: PIC16CE625 -> PIC16CE62X -> PIC16C family -> PICmicro family -> 8-bit MCU -> microcontroller -> embedded processor -> semiconductor IC. This mid-range PIC16 core uses a 14-bit instruction word and Harvard architecture (separate program and data buses), giving it deterministic instruction timing useful for timing-sensitive control loops.
Key features include an internal 4MHz RC oscillator (calibrated to +/-1 percent typical), a 10-bit successive-approximation ADC with 8 input channels, an analog comparator with programmable reference, two 8-bit timers (Timer0, Timer2) and one 16-bit timer (Timer1) with capture/compare/PWM, and the standard PIC mid-range peripheral set. The on-chip 128-byte EEPROM provides non-volatile data storage for configuration parameters and runtime calibration values without external serial EEPROM.
Typical applications include sensor-interface and transducer-conditioning front ends (where the comparator and ADC pair well), appliance and HVAC control boards, automotive body and lighting controllers, low-cost consumer IR/RF remote encoders, security-system sensor nodes, and battery-powered instrumentation. The wide 2.5V-5.5V operating range and integrated peripherals reduce BOM cost in space-constrained designs.
A key design consideration is that this OTP variant is blank at shipment and must be programmed by the user before insertion; pre-programmed code cannot be changed in-circuit. For prototyping or in-field firmware updates, consider the PIC16F625 flash-based counterpart in the same pinout, or migrate to a 16F-series pin-compatible part if program-memory updates are required during production.

Ứng dụng tiêu biểu
PIC16CE625T-04/SO phù hợp cho 6 Áp dụngs: Sensor Interface Front-End, Appliance and HVAC Control, Automotive Body and Lighting Controllers, IR/RF Remote Control Encoder, Security and Sensor Node, Battery-Powered Instrumentation.
Sensor Interface Front-End
The PIC16CE625T-04/SO is well-suited for sensor-interface front-end boards because its 10-bit ADC and analog comparator pair directly with on-chip 128-byte EEPROM calibration storage. Up to 8 analog input channels are available alongside the comparator's programmable voltage reference, allowing direct interface to thermistors, photocells, and bridge-type transducers without external signal conditioning. With 4 MHz operation delivering 1 MIPS and 13 digital I/O, the device handles both sensor reading and downstream digital control.
Được đề xuất
Appliance and HVAC Control
The PIC16CE625T-04/SO's wide operating voltage range and integrated timers make it a strong fit for appliance and HVAC controller boards. Timer0, Timer1 (with capture/compare), and Timer2 support PWM generation for valve and triac drive, while the analog comparator enables over-temperature and over-current protection. With 128 bytes of on-chip EEPROM, designers can store configuration parameters and runtime calibration values without external serial EEPROM, reducing BOM cost.
Được đề xuất
Automotive Body and Lighting Controllers
The PIC16CE625T-04/SO serves automotive body-control and lighting modules where deterministic 8-bit control and small footprint matter more than raw processing throughput. The industrial-grade -40C to +85C variant (PIC16CE625-04I/SO) drops into the same 18-SOIC footprint for under-hood and cabin environments. The CCP module generates PWM dimming signals for LED and incandescent lamps, and the comparator monitors current-sense feedback for fault protection.
Được đề xuất
IR/RF Remote Control Encoder
Battery-powered remote controls benefit from the PIC16CE625T-04/SO's low operating current, integrated timers for carrier generation, and compact 18-SOIC package. Timer0/1 can synthesize 38 kHz / 40 kHz IR carriers while Timer2 generates the PWM envelope for protocol encoding (RC5, NEC, SIRC). The 128-byte EEPROM stores device ID and pairing information, and the wide 2.5V-5.5V supply range supports 2xAA and CR2032 lithium chemistries directly.
Được đề xuất
Security and Sensor Node
The PIC16CE625T-04/SO forms the core of low-cost security-system sensor nodes (PIR motion detectors, glass-break detectors, smoke-alarm interfaces). Its on-chip EEPROM stores zone ID and tamper-detection flags non-volatilely, while the ADC monitors battery voltage for low-battery warning. The 4 MHz clock and 1 MIPS throughput handle PIR signal processing (about 100 Hz sample rate) and supervisory polling without external oscillator components.
Được đề xuất
Battery-Powered Instrumentation
Battery-powered instrumentation such as handheld multimeters, data loggers, and portable test equipment leverages the PIC16CE625T-04/SO's wide operating voltage and integrated peripherals. The 128-byte EEPROM records calibration constants and last-measured values across power cycles, while the ADC samples transducer outputs and the comparator triggers low-battery alerts. The 18-SOIC package and tape-and-reel shipping integrate cleanly with modern SMD pick-and-place lines used in commercial instrument manufacturing.

Ghi chú thiết kế
The PIC16CE625T-04/SO uses OTP (One-Time-Programmable) program memory. Unlike flash-based parts, OTP cannot be erased or rewritten, so any code bug discovered after programming is permanent. Design teams should fully debug firmware on a flash-based equivalent (e.g. PIC16F625 in the same 18-SOIC footprint) before committing to OTP programming. Verification using the MPLAB PM3 programmer with verify-after-program is mandatory in production.
Decouple VDD (pin 18) with a 100 nF ceramic capacitor placed as close to the IC as possible, plus a bulk 10 uF tantalum or aluminum capacitor at the board power entry. The 18-SOIC package's lead inductance can cause voltage transients during fast I/O switching; a low-ESR ceramic bypass (X7R or X5R dielectric) directly across VDD/VSS (pins 18 and 8) is the most effective mitigation.
When using the internal RC oscillator, leave OSC1/OSC2 unconnected or tie to known levels per datasheet; otherwise route a short, ground-guarded trace to an external crystal if used. The MCLR pin (pin 1) should have a 10 kohm pull-up to VDD and a 100 nF cap to VSS to filter noise - leaving MCLR floating or with weak pull-up causes spurious resets in electrically noisy environments like motor-control boards.
For analog inputs (RA0-RA5), short the analog trace to the ADC pin and avoid running digital signals in parallel on adjacent layers. The 10-bit ADC's sample-and-hold acquisition time requires the source impedance to be below 10 kohm for full accuracy. Add a 100 nF bypass cap close to each analog pin driving high-impedance sensors to limit noise pickup during conversion.
