PIC16LCE625T-04I/SS Descripción general
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and I/O peripherals. The PIC architecture uses a Harvard RISC design with separate program and data buses, allowing instruction fetch and data access to occur in the same clock cycle. Within the broader semiconductor hierarchy, MCUs belong to logic ICs > microcontrollers > embedded processors > semiconductors. The 'CE' family designation indicates integrated EEPROM data memory, a feature that distinguishes PIC16CE62X from the parallel PIC16C62X series and makes the 'LCE' variant suitable for applications requiring non-volatile parameter storage without external EEPROM chips.
Key features of the PIC16LCE625T-04I/SS include 35 instructions, a 14-bit instruction word, eight-level deep hardware stack, and direct/indirect/relative addressing modes. Peripherals comprise a Timer0 8-bit counter/timer with 8-bit prescaler, Timer1 16-bit counter/timer, capture/compare/PWM (CCP) module, and a 10-bit analog-to-digital converter (ADC). The 13 I/O pins can be individually configured for digital input or output, with several pins shared with analog and peripheral functions.
Architecturally, the PIC16LCE625 employs CMOS technology with low-power operation suitable for battery-powered and industrial applications. The OTP program memory is programmed once and is non-erasable; for development cycles, windowed CERDIP variants provide UV-erase capability. The integrated 128-byte EEPROM is rated for 1 million erase/write cycles, providing reliable non-volatile storage for user calibration data, configuration parameters, or runtime logs.
Typical applications include industrial control subsystems, sensor interface modules, automotive body electronics (pre-CAN era), appliance control boards, and low-power embedded sensor nodes. The combination of OTP program memory, integrated EEPROM, and 13 I/O makes this part suited for cost-sensitive high-volume products where firmware is finalized before mask programming.
A key design consideration: the 'LCE' suffix indicates low-voltage (LC) operation with EEPROM data memory; the 'T' suffix denotes tape-and-reel packaging; the 'I' indicates the industrial temperature range (-40C to +85C); and the '/SS' suffix confirms the 20-pin SSOP package footprint. Designers should verify oscillator configuration bits for RC, XT, or HS modes based on system clock accuracy requirements.

Aplicaciones típicas
PIC16LCE625T-04I/SS es adecuado para 6 aplicacións: Industrial Sensor Interface Module, Appliance Control Board (HVAC, Washing Machine), Automotive Body Electronics (Pre-CAN Era), Battery-Powered Sensor Node, User Interface Keypad Scanner, Lighting Control Module.
Industrial Sensor Interface Module
The PIC16LCE625T-04I/SS is well suited for industrial sensor interface modules that read 4-20 mA analog signals and digital switches. Its 13 I/O pins provide ample channels for multiplexed sensor inputs, while the integrated 128-byte EEPROM stores calibration coefficients and sensor identity over the part's million-cycle endurance. The 4MHz clock rate is sufficient for averaging 10-bit ADC samples at 100 Hz update rates, and the BOR/WDT peripherals protect against brown-out events common in factory 24V rails. Industrial temperature range (-40C to +85C) matches IEC 60068-2-1/2 environmental stress testing requirements. Estimated: at 5V supply and 4MHz, active current is approximately 2 mA per the PIC16CE62X datasheet, making this part suitable for always-on modules.
Recomendado
Appliance Control Board (HVAC, Washing Machine)
The PIC16LCE625T-04I/SS fits appliance control boards that drive relays, triacs, and user-interface keypads. The 13 I/O drive directly bipolar transistors or optocouplers for mains-isolated loads, while the CCP module generates PWM for motor speed control. The 128-byte EEPROM retains user-set programs (wash cycle, thermostat target) across power cycles. OTP program memory is acceptable for cost-driven appliance designs where firmware is finalized before mask programming. The Watchdog Timer protects against firmware lockup during electrical noise events typical of motor-driven systems. The 20-pin SSOP package is small enough for compact control boards but large enough for hand-rework during factory service.
Recomendado
Automotive Body Electronics (Pre-CAN Era)
The PIC16LCE625T-04I/SS is appropriate for legacy automotive body modules such as seat controllers, mirror adjusters, and interior lighting where CAN/LIN is not required. The industrial temperature rating survives the -40C cold-start and under-hood thermal soak requirements. The BOR peripheral prevents undefined behavior during cranking voltage dips, and the integrated EEPROM stores position memory for power windows and mirrors. The 4MHz clock provides adequate timing resolution for PWM-driven actuators. Note: for new automotive designs, Microchip recommends AEC-Q100-qualified PIC16F equivalents over this obsolete industrial-grade part. The SSOP-20 footprint is compatible with high-volume pick-and-place automotive assembly lines.
Recomendado
Battery-Powered Sensor Node
The PIC16LCE625T-04I/SS can serve in low-duty-cycle battery-powered sensor nodes where sleep current dominates battery life. The PIC16CE62X SLEEP mode drops current to microampere levels (estimated: 1 uA typical per the PIC16CE62X datasheet, exact value requires verification), enabling multi-year battery life when waking hourly to take a sensor reading. The 128-byte EEPROM logs up to 64 measurement records at 2 bytes each. The WDT wakes the MCU from sleep at programmable intervals. The 4MHz active clock supports rapid ADC conversion before returning to sleep. Compared to modern PIC16F1xxx parts, this device consumes more active current but remains viable for legacy products.
Recomendado
User Interface Keypad Scanner
The PIC16LCE625T-04I/SS supports 4x4 or 5x3 matrix keypad scanning with 13 I/O pins allocated across rows and columns. The interrupt-on-change feature on PORTB wakes the MCU on keypress without continuous polling, minimizing current consumption. The 128-byte EEPROM stores user PIN codes and configuration menus, retaining data through power-off. The 4MHz clock scans a 16-key matrix in under 1 ms, well below human perception thresholds. The SSOP-20 package mounts directly behind the keypad PCB, simplifying the mechanical integration. OTP program memory is acceptable because keypad scan firmware rarely changes after product release.
Recomendado
Lighting Control Module
The PIC16LCE625T-04I/SS can drive LED lighting controllers and dimmer circuits in architectural lighting applications. The CCP module generates 1 kHz PWM at sufficient resolution for 256-step dimming, while the 13 I/O pins control up to 6 RGB channels plus auxiliary inputs. The integrated EEPROM stores scene presets and fade timings across 128 bytes. The industrial temperature range accommodates LED fixture thermal environments near 70C. The BOR peripheral prevents flicker during AC mains brown-outs. The SSOP-20 package profile keeps the controller below 2 mm height for slim fixture housings. Compared to dedicated LED driver ICs, this MCU provides flexibility for custom lighting protocols.

Notas de diseño
The PIC16LCE625T-04I/SS requires a stable VDD supply; place a 100 nF ceramic decoupling capacitor within 5 mm of pin 14 (VDD) and a 10 uF bulk capacitor at the board entry point. The LC variant operates from 2.5V to 6.0V (verify exact range from datasheet Section 17); use an MCP1700 LDO if the upstream rail exceeds 6V. Brown-out Reset (BOR) must be enabled in the configuration word to prevent code execution at unsafe voltages. Estimated active current at 4 MHz / 5V is approximately 2 mA per the PIC16CE62X datasheet family specification.
Do not assume the PIC16LCE625T-04I/SS is interchangeable with PIC16F628A-I/SS or other PIC16F flash-based parts - the pinout, configuration words, and instruction set differ. Use only PIC16CE62X family parts (PIC16CE623/624/625 variants) as drop-in replacements. OTP program memory cannot be erased; a windowed CERDIP variant is required for development and firmware iteration. The 'T' suffix denotes tape-and-reel packaging, not a temperature grade - check the I/E suffix for the temperature range.
The PIC16LCE625T-04I/SS oscillator configuration is set by configuration word bits FOSC1:FOSC0 and must match the external crystal or resonator used. For 4 MHz operation, select XT mode (typical) with 20-33 pF load capacitors. HS mode is required above 4 MHz but exceeds the -04 speed grade limit. RC oscillator mode saves cost but reduces timing accuracy to approximately 5-10%; use it only for non-timing-critical applications. The CLKOUT pin (OSC2) can drive another MCU in master mode if needed.
