PIC16CE623-30/SO 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data memory, and peripheral I/O onto one silicon die. Within the broader taxonomy, the PIC16CE623 belongs to the PIC16 mid-range family -> 8-bit RISC microcontroller -> embedded controller -> semiconductor. The 14-bit instruction word and 35 single-word instruction set make PIC16CE623 part of Microchip's mid-range architecture, providing a balance between code density, deterministic execution, and ease of programming through MPLAB IDE.
Key features include a 133 ns instruction execution time at 30 MHz oscillator input, an internal brown-out reset, a watchdog timer with on-chip RC oscillator, and an analog comparator. The integrated EEPROM data memory allows non-volatile storage of calibration data, configuration parameters, or usage counters without external serial EEPROM, reducing BOM cost and board area. The PIC16CE623 also offers programmable code protection and a power-saving sleep mode with wake-up on pin change.
Typical applications include sensor signal conditioning, low-power remote controls, small appliance control boards, automotive body electronics (where appropriate AEC-Q grade is selected), battery chargers, and LED lighting controllers. The 13 I/O pins support direct LED drive, button input scanning, and serial communication via software-implemented protocols such as UART, I2C (master mode), and SPI.
When designing with this device, verify oscillator selection (RC, LP, XT, HS modes) against the system clock accuracy requirement and reserve the MCLR pin for hardware reset unless the internal configuration is used. The 18-pin SOIC wide package simplifies hand-soldering and visual inspection during prototyping but occupies more board area than the SSOP-20 alternative.
This page synthesizes distributor stock, parametric drop-in alternatives from the same Microchip PIC16C/PIC16F family, and practical design notes not consolidated on the manufacturer datasheet, helping engineers and procurement teams shorten the selection cycle for cost-sensitive 8-bit designs.

主な用途
PIC16CE623-30/SO の用途: 6 件s: Low-Cost Sensor Signal Conditioning, Battery-Powered Remote Control, Small Appliance Control Board, Automotive Body Electronics (NRND-grade), Battery Charger Controller, LED Lighting Controller.
Low-Cost Sensor Signal Conditioning
The PIC16CE623-30/SO fits sensor signal conditioning front-ends because its two on-chip analog comparators and 13 I/O pins allow direct interface to thermistor, photocell, or hall-effect sensors without external op-amps. The 30 MHz instruction cycle delivers 7.5 MIPS, enabling real-time linearization of NTC thermistor curves in firmware within 1 ms latency. With 128 bytes of integrated EEPROM, calibration constants persist across power cycles, eliminating external serial EEPROM and reducing BOM cost. Operating from 3.0 V to 5.5 V matches typical transducer bridge supplies, and brown-out reset prevents corrupted readings during battery droop. For low-volume industrial sensors, this MCU replaces dedicated ASICs at one-tenth the cost.
おすすめ
Battery-Powered Remote Control
The PIC16CE623-30/SO suits handheld remote controls thanks to its sub-microamp sleep current, integrated watchdog, and 3.0 V minimum operating voltage compatible with two AA cells. The 14-bit instruction set keeps button-scan and IR-modulation firmware compact, and the 96 bytes SRAM holds debounce state plus protocol buffers for NEC or RC-5 transmission. The internal brown-out reset ensures clean recovery when batteries drop below 2.7 V, and the 30 MHz CPU lets a single button press trigger IR LED PWM modulation within 9 instruction cycles for accurate 38 kHz carrier generation.
おすすめ
Small Appliance Control Board
The PIC16CE623-30/SO is well matched to small appliance control boards such as coffee makers, fans, and bread machines where 13 I/O pins drive relays, triacs, and seven-segment LED displays directly. The 7.5 MIPS throughput allows simultaneous zero-cross detection, triac firing delay calculation, and button matrix scanning in firmware without jitter. Integrated 128-byte EEPROM stores user presets (brew strength, fan speed), and code protection prevents end-user firmware theft. The 18-pin SOIC wide package eases hand-soldering during low-volume production, and industrial -40C to +85C temperature rating handles kitchen thermal stress.
おすすめ
Automotive Body Electronics (NRND-grade)
The PIC16CE623-30/SO appears in cost-sensitive automotive body modules such as interior lighting dimmers and seat-position switches where AEC-Q100 qualification is not strictly mandated. The 30 MHz CPU executes CAN software-stack fragments at adequate throughput for non-safety-critical nodes, and the integrated watchdog satisfies OEM reliability expectations. However, new automotive designs should migrate to AEC-Q100-qualified parts such as PIC16F1827-E/SO to meet IATF 16949 traceability requirements. The 18-pin SOIC package handles automotive underhood thermal swings within its industrial temperature range for cabin-mounted modules.
おすすめ
Battery Charger Controller
The PIC16CE623-30/SO can implement CC/CV charge profiles for lead-acid or NiMH battery packs by reading shunt voltage with its on-chip comparators and PWM-driving a MOSFET with Timer0. The integrated EEPROM retains charge-cycle counters and last-used parameters through power loss, while brown-out reset prevents deep-discharge damage. At 30 MHz, the firmware reads the battery voltage every 10 ms with 8-bit resolution, supporting chargers up to 5 A without external ADC. The wide 3.0 V to 5.5 V supply range accepts 6 V wall-adapter inputs directly through a regulator.
おすすめ
LED Lighting Controller
The PIC16CE623-30/SO drives multi-channel LED strings in architectural lighting fixtures via software PWM generated on 13 I/O pins. The 7.5 MIPS throughput allows 10-bit PWM at 1 kHz refresh across 8 channels simultaneously, exceeding the 100 Hz flicker-fusion threshold for human perception. The integrated EEPROM stores color presets and dim levels, and the watchdog timer recovers from firmware lock-ups caused by ESD transients on long LED cable runs. The 18-pin SOIC wide package supports reflow soldering and offers better thermal dissipation than SSOP variants when driving 20 mA per pin continuously.

設計ノート
Do not assume that PIC16CE623-30/SO is flash-reprogrammable in-circuit - it is OTP, meaning firmware can only be written once via high-voltage VPP on the MCLR pin during production programming. Use MPLAB PM3 or PICkit 3 with high-voltage programming mode during board bring-up; if field updates are required, migrate to PIC16F628-20/SO which shares the same 18-pin SOIC footprint.
Place a 100 nF decoupling capacitor within 5 mm of the VDD pin (pin 14) and a 10 uF bulk capacitor near the SOIC package. For HS oscillator mode above 8 MHz, add a 1 kohm series resistor on OSC2 and use a fundamental-cut crystal with 20 pF load capacitors tied to VSS. Avoid routing high-speed signal traces under the IC to minimize capacitive coupling into the analog comparator inputs on RA0/RA1.
Configure the watchdog timer postscaler to a conservative interval (e.g. 2.3 s) and clear the WDTCON register from at least one main loop branch to prevent unintended resets in sleep-mode applications. The MCLR pin must be tied to VDD through a 10 kohm resistor when not used, otherwise the floating input can trigger spurious resets during ESD events.
