PIC16CE625T-20/SO Descripción general
A microcontroller (MCU) is a single-chip computer containing a CPU core, non-volatile program memory, working RAM, and programmable I/O peripherals. The PIC16CE625 belongs to the PICmicro mid-range family of 8-bit microcontrollers, which historically dominated low-power and cost-sensitive embedded designs. OTP program memory means the device is programmed once at production and is non-erasable, distinguishing it from flash-based PIC16F variants; this positioning makes PIC16CE625 ideally suited for high-volume consumer and industrial applications where cost per unit is paramount and in-field firmware updates are not required.
Key features include 13 programmable digital I/O pins with independent direction control, an internal 4 MHz calibrated RC oscillator, an external oscillator option up to 20 MHz, a 10-bit analog comparator module, a programmable 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. The device supports a wide 2.5V to 5.5V supply range, hardware USART/SCI, and includes in-circuit serial programming (ICSP) capability via two dedicated pins, enabling programming after PCB solder. CMOS technology keeps typical active current under 2 mA at 5V/4 MHz and standby current in the microamp range.
Typical applications include appliance control boards, sensor signal conditioning front-ends with on-chip comparator, simple user-interface controllers (LED drivers, keypads), low-cost motor drivers for small DC fans and solenoids, and battery-powered portable instruments where the EEPROM data memory can store user settings and calibration values. The 18-SOIC wide-body package allows hand-soldering and rework while still providing compactness.
When designing with PIC16CE625T-20/SO, select an external clock source that matches the application's timing budget; the 20 MHz ceiling delivers 5 MIPS but increases power dissipation versus 4 MHz operation. Always reserve the ICSPDAT/ICSPCLK pins for in-circuit programming access, and ensure the MCLR pin has the proper pull-up configuration.

Aplicaciones típicas
PIC16CE625T-20/SO es adecuado para 6 aplicacións: Appliance Control Boards, Sensor Signal Conditioning Front-Ends, User Interface Controllers (LEDs, Keypads), Low-Cost Motor Drivers (Small DC Fans, Solenoids), Battery-Powered Portable Instruments, Security and Access Control Panels.
Appliance Control Boards
The PIC16CE625T-20/SO fits appliance control boards (washing machines, dishwashers, microwave ovens) because its 3.5 KB OTP memory holds fixed control firmware, 13 I/O pins drive relays and keypads, and the 20 MHz CPU delivers responsive real-time loop execution. The 128-byte EEPROM stores user-set cycles and calibration values that survive power cycles. Its industrial-grade noise immunity and 2.5V-5.5V supply range accommodate the noisy motor environment typical of household appliances.
Recomendado
Sensor Signal Conditioning Front-Ends
The PIC16CE625T-20/SO suits analog sensor front-ends where the on-chip 10-bit analog comparator thresholds and conditions signals from thermocouples, photodiodes, or capacitive touch electrodes. Its 20 MHz throughput enables up to 5 MIPS for digital filtering of the conditioned signal, while 128 bytes of RAM hold intermediate filter state. The 128-byte EEPROM retains calibration constants across power cycles, critical for accurate sensor readings in field-deployed instruments.
Recomendado
User Interface Controllers (LEDs, Keypads)
For LED drivers and keypad matrix scanners in consumer electronics, the PIC16CE625T-20/SO provides exactly the right mix of 13 digital I/O pins, 3.5 KB code space for state-machine firmware, and 128-byte EEPROM for storing user preferences (volume, brightness). The 20 MHz clock supports multiplexed 7-segment LED scanning without visible flicker. OTP programming prevents unauthorized firmware copying of finished UI designs, an advantage in consumer products.
Recomendado
Low-Cost Motor Drivers (Small DC Fans, Solenoids)
The PIC16CE625T-20/SO drives small DC fan motors and solenoid valves via PWM output on TMR0 or TMR1, with the 20 MHz instruction rate providing fine-grained PWM resolution for smooth motor control. The 13 I/O pins handle H-bridge direction signals, tachometer feedback, and fault inputs. EEPROM stores last-used fan speed or valve position across power cycles. Operating from 2.5V-5.5V supports both 3.3V logic-level and 5V driver designs.
Recomendado
Battery-Powered Portable Instruments
Battery-powered handheld meters and portable diagnostic tools benefit from the PIC16CE625T-20/SO's CMOS low-power design drawing under 2 mA active at 4 MHz and microamp-range sleep current. The 2.5V minimum supply lets the device run from two AA cells or a single Li-ion cell at 3.0V nominal. EEPROM data memory preserves measurement logs and user settings when batteries are removed. The 18-SOIC package is compact enough for handheld form factors.
Recomendado
Security and Access Control Panels
The PIC16CE625T-20/SO is used in security keypad panels and simple access control readers where OTP memory protects the proprietary authentication algorithm from extraction. The 13 I/O pins drive the keypad matrix, status LEDs, relay output for door strikes, and serial link to a central controller. The 128-byte EEPROM stores encrypted credential data that survives power-loss events. Industrial-grade ESD performance makes it suitable for installation in electrically noisy environments.

Notas de diseño
The PIC16CE625T-20/SO supply range is 2.5V to 5.5V. Decouple VDD (pin 14) with a 100 nF ceramic capacitor placed within 5 mm of the pin and a 10 uF tantalum or aluminum bulk capacitor at the board's power entry. For battery applications drawing under 1 mA average, add a 100 kohm pull-up on MCLR (pin 4 configured as RA3/MCLR) to ensure defined reset behavior at power-up.
Place the 18-SOIC footprint on a 300-mil-wide SOIC land pattern, ensuring the ICSP pins RB6 (pin 12) and RB7 (pin 13) are routed to test pads or a 6-pin ICSP header for in-circuit serial programming. Keep the OSC1/OSC2 traces short and surrounded by ground pour to minimize clock noise coupling into adjacent analog comparator inputs on RA0/RA1.
PIC16CE625 OTP memory cannot be erased or reprogrammed. Before OTP programming in production, always validate firmware on a flash-equivalent PIC16F630 or PIC16F676 prototype. Brown-out detection must be enabled via the CONFIG register to avoid code runaway at low VDD, and the Watchdog Timer should be enabled in long-loop firmware to recover from unexpected hangs.
