PIC16CE624-04I/P 概要
What is a PIC16 OTP microcontroller? The PIC16CE62X series sits within Microchip's mid-range 8-bit PIC architecture - an enhanced version of the baseline PIC16C5X core with 14-bit instruction words, a deeper call stack, and integrated analog peripherals. OTP microcontrollers (One-Time Programmable) are designed for cost-sensitive, low-volume production where the firmware is finalized before manufacture, in contrast to flash-based PIC16F parts that support in-circuit reprogramming. This family is part of the broader PIC16 -> PICmicro -> 8-bit MCU -> microcontroller -> semiconductor hierarchy.
Key features include 13 digital I/O pins, two on-chip analog comparators, a programmable voltage reference, a watchdog timer with its own on-chip RC oscillator, power-on reset, brown-out reset, and an 8-bit timer/counter with a 16-bit mode option. The device supports in-circuit serial programming (ICSP) via two pins, allowing code update after PCB assembly. Upward code compatibility with PIC16C5X and PIC12CXXX devices allows developers to reuse existing assembly code or migrate designs upward to higher pin-count PIC16CE62X variants.
Typical applications include appliance controls, sensor signal conditioning with on-chip comparators, low-cost motor control, automotive interior subsystems (under-hood nodes require the extended -40C to +125C grade), battery chargers, security keypads, and industrial sensor interfaces where the 18-pin footprint is sufficient and OTP cost savings outweigh flash reprogrammability.
When designing with this part, note that OTP memory cannot be erased - code bugs in the field require physical part replacement. The on-chip comparators enable the part to replace external analog components in battery-monitoring and signal-conditioning circuits, reducing BOM cost. The PIC16CE624-04I/P supports ICSP for programming after PCB assembly, simplifying manufacturing.

主な用途
PIC16CE624-04I/P の用途: 6 件s: Appliance Control Boards, Battery-Powered Sensor Conditioning, Security Keypads and Access Modules, Industrial Sensor Interfaces, LED Display and Indicator Drivers, Automotive Interior Accessories.
Appliance Control Boards
The PIC16CE624-04I/P's 1.75 KB OTP program memory, 13 I/O pins, and 4 MHz clock are well matched to fixed-function appliance controllers such as washing-machine front panels, microwave keypads, and dishwasher cycle timers. Its two on-chip comparators replace external op-amps for sensing water level, motor current, or door-switch position, shrinking BOM cost. The 18-pin PDIP through-hole package supports hand-soldered or wave-soldered assembly on economy-class control boards where factory firmware is finalized before production.
おすすめ
Battery-Powered Sensor Conditioning
The PIC16CE624-04I/P operates from 3.0 V to 5.5 V and draws microamp standby currents, suiting 2-cell alkaline or single-cell Li-ion powered sensor nodes. Its two comparators and programmable voltage reference enable direct interface to thermocouples, photodiodes, or Hall-effect sensors without external analog front-end ICs. The 128-byte EEPROM stores per-unit calibration constants across temperature, while 96 B RAM supports running averages and threshold detection in 4 MHz firmware loops.
おすすめ
Security Keypads and Access Modules
In PIN-pad door locks and alarm keypads, the PIC16CE624-04I/P serves as a cost-optimized controller scanning up to a 4x4 matrix (13 I/O pins available). The 128-byte EEPROM retains user credentials and event logs across power cycles, and the OTP program memory locks down the firmware against field tampering - a security advantage over flash parts. Industrial -40C to +85C operation covers indoor commercial and residential installations worldwide.
おすすめ
Industrial Sensor Interfaces
The PIC16CE624-04I/P's 13 I/O, programmable Vref, and two analog comparators make it a building block for 4-20 mA loop transmitters, RTD signal conditioners, and bridge-sensor readout modules in industrial settings. The comparators generate interrupts on threshold crossings, allowing the MCU to wake from sleep on a process event and minimize average current in loop-powered applications. The 18-pin PDIP footprint fits legacy 24 V industrial PLC I/O module layouts.
おすすめ
LED Display and Indicator Drivers
Each PIC16CE624-04I/P I/O pin sinks up to 25 mA, allowing direct drive of common-cathode 7-segment displays, status LEDs, and optocouplers without external transistor arrays. The 13 outputs drive a 2-digit 7-segment plus status LED cluster easily, with 96 B RAM storing display buffers and BCD-to-7-segment lookup. The 200 ns instruction cycle updates displays at >100 kHz refresh, well above the 100 Hz flicker threshold.
おすすめ
Automotive Interior Accessories
For non-safety automotive accessories such as interior lighting controllers, seat-heater keypads, and auxiliary display modules, the PIC16CE624-04I/P provides the I/O count and analog comparators needed for switch-matrix scanning and temperature-feedback loops. Its 4 MHz operation is sufficient for slow human-interface response times. For under-hood or powertrain nodes, select the PIC16CE624-04E/P extended temperature grade instead, since this part tops out at -40C to +85C (industrial range).

設計ノート
PIC16CE62X parts use OTP (One-Time Programmable) EPROM - code bugs in production cannot be erased by UV or ICSP. Always validate firmware on a flash-based equivalent (PIC16F627A) before committing to OTP, and use Microchip's ICSP tooling (PGD/PGC on RB6/RB7) to program the part after PCB assembly. Verify configuration bit settings for watchdog, brown-out, and oscillator mode before programming since OTP fuses cannot be reset.
Place the 0.1 uF VDD decoupling capacitor within 5 mm of pin 14 with a short ground return to pin 5. The 18-pin PDIP package has substantial lead inductance, so add a 10 uF bulk capacitor near the VDD pin for motor or relay loads. Keep the OSC1/OSC2 traces short and shielded with ground; for crystal operation add 22 pF load caps from each oscillator pin to ground, sized per the crystal's load specification.
Brown-out reset (BOR) is enabled by configuration bit and holds the device in reset when VDD drops below ~4.0 V (configurable). For battery-powered designs using two alkaline cells (nominally 3.0 V), disable BOR or set it to the lowest threshold to avoid spurious resets as the battery discharges. The on-chip comparators can be used to monitor VDD via the internal bandgap reference, providing a software-managed low-battery warning.
The 18-pin PDIP footprint is through-hole with 0.1 inch (2.54 mm) pin pitch - the standard DIP-18 land pattern is compatible with all PDIP-18 PIC16CE62X variants and most 18-pin through-hole footprints. Pin 1 is at the top-left when the notch faces up (industry-standard DIP orientation). The RA4 pin is open-drain and requires a pull-up resistor when used as a digital output driving a logic-high level.
コンプライアンス情報
Lead-free / RoHS status not explicitly listed in the verified web snippets for this exact suffix. Microchip's general product family (PIC16CE62X) is generally lead-free; however, the 18-pin PDIP variant historically shipped in both leaded and lead-free finishes. Verify with the manufacturer's product page before assuming compliance for any specific date code or lot.
