PIC16CE624T-04/SO Übersicht
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, working RAM, EEPROM, and programmable I/O peripherals. OTP microcontrollers use one-time-programmable memory that is programmed after manufacture and cannot be erased, making them low-cost and well-suited for high-volume production where firmware is stable. The PIC16CE62X series sits in Microchip's mid-tier 8-bit PIC family, upwards compatible with the PIC16C5X and PIC12CXXX devices, and is designed for entry-level applications in automotive, industrial, appliance, and consumer markets.
Key features of the PIC16CE624 include two analog comparators with programmable reference, a Brown-Out Detect (BOD) circuit, Power-On Reset (POR), Watchdog Timer (WDT) with its own on-chip RC oscillator, and 13 general-purpose digital I/O pins. The integrated 128-byte EEPROM supports non-volatile data storage, removing the need for an external serial EEPROM in simple data-logging designs. The 4 MHz internal/external clock and 1K-word OTP program memory support small to mid-sized embedded control loops.
The PIC16CE624 uses a Harvard-architecture RISC core with separate code and data buses, an 8-level deep hardware stack, and five I/O ports grouped into PORTA (5 pins) and PORTB (8 pins). The on-chip EEPROM supports >1 million erase/write cycles and 40-year retention per the Microchip datasheet, which is appropriate for parameter storage, serial-number retention, and user-setting memory in appliance and consumer products.
Typical applications include white-goods and appliance control (washing-machine user-interface boards, microwave ovens), industrial sensor transmitters, low-end automotive body modules, security keypads, and small consumer devices. The combination of analog comparators, EEPROM, and small OTP code memory fits designs that previously required a multi-chip analog + EEPROM + MCU solution.
When designing with the PIC16CE624T-04/SO, ensure the supply rail is decoupled with at least 0.1 µF ceramic placed within 5 mm of VDD, and confirm that the MCLR pin pull-up and reset-capacitor network match the PIC16C62X family reference design in the datasheet. Note that this part is OTP, not Flash, so firmware must be fully validated on the PIC16CE624-04/SO (windowed or EPROM equivalent) before high-volume programming.

Typische Anwendungen
PIC16CE624T-04/SO ist geeignet für 6 Anwendungs: White Goods and Appliance Control, Industrial Sensor Transmitters and Process Meters, Low-End Automotive Body and Convenience Modules, Security Keypads and Access-Control Panels, Consumer Electronics Remote Controls and Toys, Smart Home Sensor Nodes and IoT Edge Devices.
White Goods and Appliance Control
The PIC16CE624T-04/SO is well-suited for white-goods appliance control boards (washing-machine user interfaces, microwave-oven keypads, dishwasher controllers) because its 4 MHz RISC core, 1Kx14 OTP program memory, and 128-byte on-chip EEPROM are sufficient for the small firmware image plus user-setting retention needed in these designs. The 128-byte EEPROM stores wash-cycle selection, calibration values, and serial numbers across power cycles without an external serial EEPROM. The two on-chip comparators with programmable voltage reference can directly sense water-level, temperature-switch, or door-latch signals, eliminating analog front-end components. Operating from a single 5 V rail and tolerating the 0-70 °C commercial range, it fits inside sealed appliance enclosures with no heatsinking.

Industrial Sensor Transmitters and Process Meters
For 4-20 mA loop-powered or low-power industrial sensor transmitters, the PIC16CE624T-04/SO provides an integrated 8-bit ADC-free architecture that pairs two comparators with a programmable voltage reference to digitize sensor signals through slope/ramp conversion. The 128-byte EEPROM retains calibration coefficients, sensor ID, and engineering-unit conversion tables across decades of operation - critical for field-deployed transmitters that cannot be re-calibrated frequently. The 4 MHz CPU clock runs the comparator ramp algorithm and linearization math while keeping active current draw low, extending battery life in wireless or loop-powered designs. Industrial-grade variants (PIC16CE624T-04I/SO) extend the operating range to -40 °C to +85 °C for outdoor installations.
Empfohlen
Low-End Automotive Body and Convenience Modules
The PIC16CE624T-04/SO is well suited to automotive body-electronics modules such as door-lock controllers, seat-position memories, sunroof controllers, and mirror-adjust modules where modest code size, EEPROM parameter storage, and on-board analog comparators are valued. The two comparators and programmable voltage reference let the MCU monitor switch inputs and analog sensors without external analog circuitry, while the 128-byte EEPROM stores user preferences (seat position, mirror angle) across battery disconnects. The Brown-Out Detect circuit holds the MCU in reset during crank-voltage sag, preventing code runaway when the vehicle battery drops below threshold. For under-hood or harsh-environment modules, the extended-grade PIC16CE624T-04E/SO is recommended.
Empfohlen
Security Keypads and Access-Control Panels
The PIC16CE624T-04/SO fits security keypads, RFID readers, and small access-control panels where code volume is small (under 1 K words), EEPROM is needed for storing user PINs and entry logs, and where low cost plus reliability are essential. The 8-bit core runs scan-and-debounce loops on the keypad matrix efficiently, and the 128-byte EEPROM retains credentials and audit logs across power outages and tamper events. Watchdog Timer with its own RC oscillator prevents code-lockup from EMI or static discharge that may occur near door strike hardware. The two analog comparators can directly interface with tamper-switch and door-position sensors without external analog ICs.
Empfohlen
Consumer Electronics Remote Controls and Toys
The PIC16CE624T-04/SO is widely used in cost-sensitive consumer products such as universal remote controls, educational toys, small kitchen appliances, and hobby electronics. The 4 MHz core handles key-scanning, IR transmit/receive timing, and small audio-tone synthesis while keeping the active current well under 10 mA, enabling battery-powered designs that last months on alkaline cells. The 128-byte EEPROM stores user-customized settings (TV brand code, volume preset, last channel) that survive battery replacement. Surface-mount 18-SOIC packaging supports automated assembly at very low cost, fitting the price-point requirements of high-volume consumer goods.
Empfohlen
Smart Home Sensor Nodes and IoT Edge Devices
The PIC16CE624T-04/SO can serve as a low-cost edge controller in smart-home sensor nodes (temperature, occupancy, leak detectors, simple thermostat interfaces) where it aggregates analog and digital sensor data, runs a small control algorithm, and forwards events to a host processor via UART or simple protocol. The two on-chip comparators can directly detect threshold-crossing sensor events (PIR motion detectors, leak probes, light-level thresholds) without external analog components. The 128-byte EEPROM stores configuration and last-known-state across Wi-Fi/co-processor power-cycles, and the BOD/POR functions survive brownouts caused by switching power-supply glitches. Modern designs would consider PIC16F1827-I/SO for active production, but the PIC16CE624 remains in legacy installed bases.

Designhinweise
Decouple VDD (pin 14) with at least 0.1 µF ceramic placed within 5 mm of the IC, plus a bulk 1-10 µF tantalum or aluminum on the supply rail. The PIC16CE624 has very fast edge transitions on I/O pins; insufficient decoupling can cause code runaway that the Watchdog Timer must catch. Add a 10-100 Ω ferrite bead or small inductor on the VDD trace when the supply is shared with motors or relays. Brown-Out Detect should be enabled (BODEN configuration bit) to hold the MCU in reset when VDD falls below ~4.0 V, preventing erratic code execution during crank or load-dump events.
Route the crystal (or resonator) traces between OSC1 (pin 16) and OSC2 (pin 15) as short as possible and keep them away from switching traces or high-current signals. Place the crystal case ground pin directly to a ground island tied to VSS (pin 5) with a single short trace to avoid ground loops. MCLR/VPP (pin 4) requires a 10-100 kΩ pull-up to VDD for normal operation and a 0.01-0.1 µF capacitor to ground for noise filtering; the resistor-capacitor time-constant is application-dependent. Keep RB6/PGC and RB7/PGD away from analog comparator input pins RA0-RA3 to prevent programming noise from coupling into sensitive analog measurements.
Do not assume the PIC16CE624T-04/SO can be re-programmed in-circuit - it is OTP, so firmware bugs discovered after programming cannot be corrected without scrapping the part. Always validate firmware on the PIC16CE624-04/JW (windowed/EPROM) emulator or on a Flash-based equivalent (PIC16F627A-I/SO) before committing to volume programming. Do not leave unused I/O pins floating - configure them as outputs or tie them to VDD/VSS through a resistor, since floating inputs can cause shoot-through currents and unpredictable code paths. Do not exceed 25 mA total into any I/O port (PORTA or PORTB) or 200 mA total VDD current per the absolute-maximum ratings.
When using the on-chip comparators with the programmable voltage reference, place the VREF load (pin 1) trace away from digital switching signals; the reference is shared with the comparator threshold and ripple on it directly couples into comparator output noise. For sensor interfaces that switch below 1 mV, add a small RC low-pass filter (1-10 kΩ, 0.01 µF) at the comparator input pin to filter EMI. The 128-byte EEPROM is sensitive to VDD brownouts during write cycles - the BOD should be enabled and the write completion should be verified by reading back the saved value before proceeding with subsequent operations.
