PIC16LCE623-04E/P - 8-Bit 4MHz OTP MCU 896B | Microchip
MPN: PIC16LCE623-04E/P ✗ Cuối đờiPIC16LCE623-04E/P Tóm tắt
An 8-bit microcontroller (MCU) is a small computer-on-a-chip containing a CPU, program memory, RAM, and peripherals designed for embedded control tasks. PIC microcontrollers use a Harvard RISC architecture that executes most instructions in a single cycle (200 ns at 20 MHz), simplifying deterministic real-time firmware development. The PIC16C family sits within Microchip's hierarchy of 8-bit MCU -> microcontroller -> embedded processor -> semiconductor, and the PIC16CE623 specifically targets low-voltage (LC suffix) applications requiring EPROM-style OTP programming at reduced cost.
Key features include 35 single-cycle instructions (except two-cycle branches), 4 MHz maximum clock input (200 ns instruction cycle), wide 2.5 V to 5.5 V supply range for battery-friendly operation, and 13 digital I/O pins. The external oscillator interface supports crystals, resonators, or external clock sources up to 4 MHz. OTP memory provides one-time field programmability at production-time cost below flash-based parts.
The architecture combines a RISC CPU core with dedicated peripheral registers, an 8-bit ALU, and a hardware multiplier-less instruction set optimized for byte and bit manipulation. The 512 x 14 program word size accommodates 14-bit opcodes, which is standard for mid-range PIC16 devices. Power management is handled by oscillator selection (LP/XT/HS modes) and sleep mode with wake-up on pin change or watchdog timeout.
Typical applications include low-power embedded control, battery-powered sensor interfaces, simple motor control loops, appliance front-panel controllers, and consumer electronics requiring small-form-factor 8-bit processing. The PIC16LCE623 family is well documented in legacy designs, hobbyist projects, and educational kits where 8-bit simplicity outweighs the need for larger flash and modern peripherals.
When designing with this device, note that OTP memory cannot be erased or rewritten; production programming must be error-free. For engineering samples or development cycles, consider the flash-based PIC16F630 family as a pin-compatible substitute. Industrial temperature grade (E suffix) supports -40C to +125C operation.

Ứng dụng tiêu biểu
PIC16LCE623-04E/P phù hợp cho 6 Áp dụngs: Battery-Powered Sensor Interface, Industrial Appliance Controller, Consumer Electronics Remote Control, Simple Motor Speed Controller, Hobbyist / Educational MCU Kit, Security / Access Control Panel.
Battery-Powered Sensor Interface
The PIC16LCE623-04E/P fits low-power sensor nodes thanks to its 2.5 V-5.5 V supply range and 4 MHz operation. With 13 digital I/O, 96 B RAM, and 128 B EEPROM, it can interface multiple digital sensors, store calibration coefficients in EEPROM, and run periodic sleep/wake cycles. Placed near a 3 V lithium coin cell, its external low-power oscillator enables multi-year battery life. Unlike higher-MHz PIC16F parts, the LCE623 trades speed for lower dynamic current, ideal for duty-cycled environmental sensors.

Ghi chú thiết kế
Estimated: At VDD=3.3 V and 4 MHz oscillator, the PIC16LCE623-04E/P draws approximately 2-5 mA active (datasheet-typical). For battery operation, use sleep mode between sensor reads with wake-on-WDT or external interrupt; idle current drops to microampere levels. Place a 100 nF decoupling capacitor within 5 mm of the VDD pin and a 10 uF bulk capacitor at the supply rail to suppress switching transients.
Keep the oscillator traces (OSC1, OSC2) as short as possible and route them away from noisy digital lines; use a guard ground around the crystal to reduce EMI coupling. Place MCLR pull-up resistor (typically 10 kOhm) close to the MCLR pin to ensure clean reset. For ICSP, route RB6/ICCLK and RB7/ICDAT to a 5-pin header with VPP, VDD, GND; this enables in-circuit OTP programming without removing the device from the board.
OTP memory cannot be erased - any code error after programming is permanent. For development cycles, use the flash-based PIC16F630-I/P as a functional substitute; the production programmer must verify code checksum before committing to OTP. Note that the LCE623's analog comparator pins (RA0-RA3) double as digital I/O - configure ANSEL register bits correctly to avoid analog mode lockup. Watchdog timer must be cleared before timeout or the part resets.
The 18-PDIP package allows standard 0.1 inch (2.54 mm) pitch through-hole footprints compatible with breadboards, perfboards, and standard IC sockets. For hand-prototyping, use a machined-pin DIP socket to allow chip removal. Keep analog input traces (RA0-RA4) short and away from switching nodes to minimize ADC comparator noise. Where possible, dedicate one ground plane for the MCU with star-ground topology to noisy peripherals.
