PIC16LCE625-04/SS - 8-bit MCU, 3.5KB OTP, 4MHz, SSOP-20 | Microchip
MPN: PIC16LCE625-04/SS ✓ نشطPIC16LCE625-04/SS نظرة عامة
A microcontroller (MCU) is a single-chip computer that integrates processor core, program memory, RAM, and peripherals into one device. The PIC16C series uses a Harvard RISC architecture with a 14-bit instruction word, optimized for deterministic execution in embedded control applications. Within the broader semiconductor taxonomy, an 8-bit MCU falls under integrated circuits > microcontrollers, and the PIC16CE6xx sub-family is positioned as a low-power, OTP-programmable generation predating the flash-based PIC16Fxxx families.
Key differentiating features include two on-chip analog comparators, a Brown-Out Detect (BOD) circuit, Power-On Reset (POR), a Watchdog Timer (WDT) for reliable operation, and an EPROM/OTP program memory that supports one-time programming at production volume. The 13 I/O pins can each be individually configured for digital input or output, and the architecture supports interrupt-driven control with low-cost external components.
This part operates across the commercial 0°C to +70°C temperature range with a 4 MHz oscillator. Designers value the PIC16CE625's combination of low-voltage operation, integrated analog comparators, and the deterministic instruction set, which together reduce BOM cost and PCB footprint in simple control loops.
Typical applications include appliance control panels, low-power sensor interfaces, security peripherals, small consumer devices, and battery-powered instrumentation. For designs migrating to flash-based parts, the PIC16F676 is a near-pin-compatible drop-in successor with the same SSOP-20 footprint and 10-bit ADC instead of comparators.
When designing with this OTP MCU, plan firmware and code patterns carefully before wafer/board commitment, since OTP does not permit field updates. Add a low-VDD detection window via the BOD threshold and reserve a debug/test pad on RA0/TOCKI for in-circuit calibration.

التطبيقات النموذجية
PIC16LCE625-04/SS مناسب لـ 6 التطبيقs: Appliance Control Panels, Low-Power Sensor Interfaces, Battery-Powered Consumer Devices, Security and Alarm Peripherals, Industrial Control Loops (Non-Safety), Automotive Interior Accessories (Legacy).
Appliance Control Panels
The PIC16LCE625-04/SS fits appliance control panels because its 3.5 KB OTP memory holds fixed control logic for washers, microwaves, and HVAC interfaces, while 13 I/O pins drive relays, keypads, and 7-segment displays. The 4 MHz clock is sufficient for slow control loops (relay timing, debounce, fan-speed PWM). The 2.0-6.0 V supply range supports 3.3 V and 5 V designs, and the integrated Brown-Out Detect prevents code corruption during brown-outs. Compared to flash MCUs, the OTP variant reduces unit cost by 20-40% in high-volume production, making it ideal for cost-sensitive appliance OEMs.

Low-Power Sensor Interfaces
The PIC16LCE625-04/SS suits low-power sensor interfaces where its two on-chip comparators connect directly to analog sensors (temperature, light, proximity) without external op-amps. The 128 bytes of RAM hold small data buffers, and the 13 I/O pins support SPI/I2C bit-banging for sensor peripherals. Operating from 2.0 V to 6.0 V, it interfaces with 3.3 V sensors and 5 V actuators alike. The 4 MHz clock and 14-bit RISC architecture deliver deterministic loop times, critical for sampling-rate-sensitive applications like thermostat controllers.
موصى به
Battery-Powered Consumer Devices
Battery-powered consumer devices benefit from the PIC16LCE625-04/SS because of its 2.0 V minimum supply voltage, which extracts the last usable energy from 2x AA cells before they reach 1.8 V cutoff. The Watchdog Timer recovers from software lockups without manual reset, and Power-On Reset ensures clean startup after battery insertion. With 3.5 KB of OTP memory holding the fixed feature set (toy logic, simple UI, LED blink patterns), the device achieves low BOM cost. The SSOP-20 package supports compact handheld form factors.

Security and Alarm Peripherals
Security peripherals such as PIR motion-sensor modules and door-contact alarm units use the PIC16LCE625-04/SS for its OTP memory (locked firmware prevents reverse engineering), two comparators (for analog sensor signal conditioning), and Watchdog Timer (for unattended operation reliability). The 13 I/O pins drive LEDs, buzzers, and relay outputs. Operating voltage down to 2.0 V accommodates backup-battery operation during mains failure. The deterministic interrupt structure ensures alarm-event response within microseconds of trigger.
موصى به
Industrial Control Loops (Non-Safety)
Industrial control loops (non-safety) such as conveyor timers, solenoid drivers, and pump controllers use the PIC16LCE625-04/SS for its BOD, POR, and WDT triad, which together deliver robust operation in electrically noisy factory environments. The 4 MHz instruction rate handles PID loop calculations at 1 kHz rates when properly optimized. The 13 I/O pins accommodate digital inputs, opto-isolated feedback, and PWM outputs. For new designs, the industrial-temperature -04I/SS variant is recommended to extend operating range to -40C to +85C.
موصى به
Automotive Interior Accessories (Legacy)
Legacy automotive interior accessories such as dome-light controllers, seat-occupancy indicator LEDs, and simple key-fob receivers have used the PIC16LCE625-04/SS for cost-optimized, code-frozen production. The 13 I/O pins handle switch inputs and LED/PWM outputs; the comparator inputs sense analog switch positions. Although modern automotive designs migrate to AEC-Q100-qualified MCUs, the SSOP-20 footprint and Microchip long-term support keep the part viable for non-safety accessory modules in commercial vehicle platforms.

ملاحظات التصميم
Estimated: at VDD=5V and 4 MHz clock, the PIC16LCE625-04/SS typical operating current is approximately 2-5 mA (per PIC16CE625 datasheet DC characteristics). Add a 100 nF decoupling capacitor directly across VDD (pin 15) and VSS (pin 18), placed within 5 mm of the package. For battery-powered designs, configure BOD peripheral zero-bias threshold to match the lowest acceptable VDD and prevent code corruption during voltage dips.
Estimated: the SSOP-20 package has a thermal resistance of approximately 90 C/W. For hand-soldering prototype boards, use 0.5 mm tip temperature-controlled iron at 310 C with lead-free SAC305 solder. For production reflow, follow JEDEC J-STD-020 profile with peak temperature of 245 C for 30 seconds maximum. Place the crystal/oscillator as close as possible to OSC1/OSC2 (pins 16-17) and guard the traces with ground pour to reduce EMI.
PIC16LCE625-04/SS uses OTP memory, so firmware cannot be field-updated - validate all code paths before wafer programming. The MCLR pin (pin 4) is also the VPP programming voltage pin; ensure external MCLR reset circuit does not exceed the datasheet VPP voltage during normal operation. The Watchdog Timer should be enabled in any safety-relevant application to recover from software lockup; failing to clear WDT in long main-loop iterations will trigger an unexpected reset.
