PIC16LCE623-04I/SS 개요
Key features include 13 general-purpose I/O pins, a 2.5 V to 5.5 V wide operating voltage range, and an industrial temperature grade of -40 °C to +85 °C. The "LCE" suffix denotes the low-power CMOS core variant designed for battery-friendly operation, while the "04" speed grade specifies 4 MHz maximum oscillator frequency and the "I" suffix indicates the industrial temperature range.
The PIC16LCE623-04I/SS uses Microchip's well-established mid-range 8-bit RISC architecture with 35 single-cycle instructions. The architecture provides deterministic timing suitable for real-time control, while the 14-bit instruction word supports direct bit manipulation, hardware register access, and interrupt-driven peripherals. Internal peripherals typically include timers, a watchdog timer, and analog comparators depending on die variant.
Typical applications span low-power consumer products, white goods and appliance controls, simple sensor interfaces, and industrial monitoring nodes. The 20-SSOP package is footprint-compatible with many PIC16Cxxx siblings, which simplifies board respins when migrating to alternate OTP or windowed variants during prototyping.
When designing with this device, ensure the oscillator configuration matches the application's EMI and power budget, and budget for OTP programming during production flow. The 20-SSOP exposed-pad variant is not used here; standard SSOP land pattern applies.

주요 차별점
- OTP memory for lowest-cost high-volume production (vs PIC16F628-I/SS)
- Industrial -40 to +85 °C temperature grade (vs PIC16C623 (commercial grade))

설계 노트
The PIC16LCE623-04I/SS operates from 2.5 V to 5.5 V and supports a sleep current under 1 µA typical, enabling battery-friendly designs. Place a 100 nF decoupling capacitor within 5 mm of the VDD pin (pin 14) and a bulk 10 µF tantalum or aluminum-polymer cap at the board power entry. For sleep-mode wakeup, configure the watchdog timer or external interrupt (RB0/INT) rather than polling, and disable unused peripherals via the CMCON and PCON registers to minimize Iq.
OTP memory cannot be erased or rewritten, so firmware bugs discovered after programming are unrecoverable on the same device. Plan for at least two programming iterations during development using PIC16F628-I/SS samples, then freeze the firmware before migrating to PIC16LCE623-04I/SS for production. Also note that ICSP programming requires MCLR/VPP to be raised to ~13 V; ensure your in-circuit programmer can drive this pin through any isolation resistor without exceeding the VDD rail.
The 20-SSOP package has a 0.65 mm pitch and a thermal pad-free body, allowing routing on a 2-layer FR4 board with 0.15 mm trace/space. Keep the oscillator traces (OSC1/OSC2, pins 15-16) under 10 mm and shield them with a ground pour to limit EMI coupling. Place the MCLR pull-up (typically 10 kΩ) within 3 mm of pin 4 and add a 100 nF cap to ground if MCLR noise is observed during in-circuit programming.
