PIC16CE624T-04E/SS Visão geral
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (ROM/RAM), and programmable I/O peripherals. The PIC® 8-bit MCU family targets cost-sensitive, deterministic, low-power embedded applications; within that hierarchy PIC16CE624 belongs to the PIC16C mid-range core (linear regulator -> MCU -> 8-bit RISC microcontroller -> embedded controller -> semiconductor). It is upwards compatible with the PIC16C5X baseline and PIC12CXXX devices, easing migration for legacy designs.
Key differentiating features include 35 single-word instructions with single-cycle execution (200ns at 4MHz, 200ns instruction cycle at 20MHz external clock input), 13 digital I/O pins, integrated analog peripherals (2 comparators with a programmable voltage reference), and system-reset peripherals: power-on reset (POR), brown-out detect/reset (BOD), and a watchdog timer (WDT). The CMOS process keeps quiescent draw low for battery-friendly designs. The 'E' suffix indicates the extended industrial temperature grade per Microchip's part-numbering convention, and 'T' indicates Tape & Reel packaging.
Typical applications span appliance control (washing machines, microwave ovens, coffee makers), security and alarm panels, low-end remote controls, sensor signal conditioning using the on-chip comparators, and small motor/solenoid drivers via the 13 GPIO. The 20-SSOP footprint saves PCB area versus the older 18-pin PDIP while retaining pin compatibility with the PIC16C62X family.
A practical design tip: since this is an OTP part, firmware must be committed at the time of programming and cannot be field-upgraded. For designs that may need late-stage firmware changes, consider a Flash-based sibling such as the PIC16F62X. Operating supply is 3.0V to 5.5V.

Aplicações típicas
PIC16CE624T-04E/SS é adequado para 6 aplicaçãos: White Goods and Appliance Control, Security and Alarm Panels, Remote Control and IR Transmitter, Sensor Signal Conditioning with Comparators, Low-End LED Lighting Control, Small Motor and Solenoid Drivers.
White Goods and Appliance Control
The PIC16CE624T-04E/SS fits white-goods appliance control because its 1.75 KB OTP program memory, 96-byte RAM, and 35-instruction PIC16 mid-range core deliver deterministic 200ns instruction execution with predictable timing for washing machines, microwave ovens, and coffee makers. According to the Microchip PIC16CE62X datasheet, its integrated brown-out detect/reset (BOD) and power-on reset (POR) protect against brown-out line-voltage faults in motor-driven loads, while the watchdog timer (WDT) recovers the controller from firmware lockups. The 20-SSOP package saves PCB area versus legacy 18-PDIP, and the -40C to +125C extended industrial temperature grade supports unheated appliance compartments.
Recomendado
Security and Alarm Panels
For security and alarm panels, the PIC16CE624T-04E/SS offers 128 bytes of EEPROM that retain user codes and event logs through power cycles, a critical feature for door-keypad and PIR-sensor hubs. The two on-chip analog comparators can directly interface with PIR motion sensors or thermistor-based fire detectors, eliminating an external op-amp stage. Per Microchip datasheet, the BOD trip point prevents the MCU from executing corrupted code during a brown-out, ensuring the alarm sounder is not falsely triggered or silenced. The OTP program memory also provides firmware read-back protection, deterring code theft in commercial security installations.
Recomendado
Remote Control and IR Transmitter
The PIC16CE624T-04E/SS suits consumer remote controls because its 13 digital I/O pins can directly drive IR LEDs, keypad scan matrices, and indicator LEDs without external glue logic. According to the Microchip PIC16CE62X datasheet, the 4 MHz internal oscillator option eliminates the external resonator, reducing BOM cost and PCB area in handheld IR transmitters. Its low CMOS quiescent current extends battery life, and the 35 single-word instructions make RC5/SIRC/NEC protocol encoding a compact firmware task. The 20-SSOP package also suits slim remote-control housings.
Recomendado
Sensor Signal Conditioning with Comparators
For analog sensor signal conditioning, the PIC16CE624T-04E/SS integrates two analog comparators with a programmable voltage reference, enabling threshold detection on thermistor, photodiode, or Hall-sensor inputs without a dedicated analog front-end IC. According to Microchip application notes, the comparators can wake the MCU from sleep on a sensor event, reducing average current draw in battery-powered monitoring nodes. Combined with the 4 MHz instruction cycle, the MCU can sample and react to comparator events within microseconds, making the part well-suited for over-temperature cutoffs and battery-cell balancing monitors in small Li-ion packs.
Recomendado
Low-End LED Lighting Control
The PIC16CE624T-04E/SS drives LED lighting controllers because its 13 I/O can sink/source LED segments directly or via low-cost MOSFET drivers, and the PIC16 instruction set supports PWM generation through software loops at 4 MHz. Per Microchip datasheet, the watchdog timer (WDT) ensures the LED controller recovers from EMI-induced firmware lockups, a common reliability concern in commercial LED drivers. The OTP memory offers low unit cost at production volume and read-back protection for proprietary dimming curves. The 20-SSOP footprint supports slim in-fixture designs.
Recomendado
Small Motor and Solenoid Drivers
For small DC-motor and solenoid control, the PIC16CE624T-04E/SS provides 13 GPIO that can drive half-bridge or H-bridge MOSFET gate drivers directly, and the 2 comparators can sense motor current via a shunt resistor for over-current protection. Per the Microchip PIC16CE62X datasheet, the BOD and POR peripherals latch the bridge in a safe state during supply-voltage dips, preventing shoot-through. The 35-instruction core executes deterministic 200ns loop cycles, simplifying PID-loop software for valve and damper actuators. The -40C to +125C extended grade supports outdoor HVAC and refrigeration compressor boards.

Principais diferenciais
- Flash re-programmability plus USART and wider supply range in the same 20-SSOP footprint (vs PIC16F628A-I/SS)
- Larger OTP program memory for richer firmware (vs PIC16CE625T-04E/SS)
- Smaller OTP option for cost-down designs (vs PIC16CE623T-04E/SS)
Notas de projeto
Decouple Vdd (pin 14) with a 100 nF ceramic capacitor placed within 5 mm of the package, plus a bulk 10 uF tantalum or ceramic on the same rail. According to the Microchip PIC16CE62X datasheet, the BOD peripheral resets the MCU when Vdd falls below the trip threshold, but slow Vdd ramps below 1 us can still cause POR failures - the decoupling network prevents this.
Route the OSC1/OSC2 traces short and symmetric to keep clock rise/fall within the 20 MHz datasheet specification. Keep the MCLR/Vpp pin trace short and avoid routing noisy switching signals across it to prevent inadvertent resets. According to Microchip layout guidelines, place the ICSP header footprint on production boards even when using an OTP part, to support factory programming without rework.
Do not assume firmware portability between PIC16CE624 OTP and PIC16F628A Flash without recompiling against the new SFR map: CONFIG word, oscillator configuration, and interrupt vector addresses differ between the two. According to Microchip migration notes, the F628A adds a USART and CCP module whose reset states must be explicitly disabled if unused, otherwise they will source unwanted interrupts. Also remember OTP parts cannot be re-programmed, so verify code with a Flash emulator (PIC16F627A) before committing.
