PIC16CE623T-04I/SO Übersicht
An OTP (One-Time Programmable) microcontroller is a non-erasable variant of the broader ROMless/ROM-based MCU family, optimized for cost-sensitive, fixed-function embedded products where firmware is finalized during production and field reprogramming is not required. Within the PIC architecture hierarchy, the PIC16CE62X family belongs to the mid-range 8-bit PIC core, sits under the dsPIC 16-bit DSC family in Microchip's portfolio, and is positioned between baseline (PIC10/12/16) and enhanced mid-range (PIC18) devices. The "CE" suffix in particular denotes an EEPROM-equipped variant, giving the PIC16CE623 persistent data storage without an external serial EEPROM, which simplifies BOM and PCB area.
Key features of the PIC16CE623T-04I/SO include 35 single-word instructions, all executing in a single 200ns instruction cycle except program branches (two-cycle), an operating speed of up to 20MHz clock input, 4MHz internal operation in this -04 speed grade, and supply voltage range of 3V to 5.5V. The device also includes 13 digital I/O pins, an external oscillator type, brown-out and watchdog peripherals common to the family, and low-power CMOS construction. The 18-pin SOIC package provides a compact 0.295" (7.50mm) body width suitable for surface-mount assemblies with constrained board area.
Architecturally, the PIC16CE623 uses a Harvard bus design with separate program and data paths, a 14-bit instruction word, and an 8-bit data path. Its EEPROM data memory provides byte-level endurance suitable for storing configuration parameters, calibration data, or user preferences that must survive power cycles. The 4MHz oscillator rating combined with the 200ns instruction cycle keeps power consumption low for always-on appliance, sensor, and consumer applications.
Typical applications include low-cost consumer electronics, appliance controllers, lighting ballasts, security and access peripherals, smart sensor front-ends, and industrial control modules. The integrated EEPROM eliminates an external 24Cxx serial EEPROM, reducing BOM cost and I/O pin overhead in space-constrained designs. Engineers choose this device when cost is critical, firmware is finalized at production, and a small amount of non-volatile data storage is required.
When designing with the PIC16CE623T-04I/SO, reserve the device's only programming pin (RB3/PGM) and ensure that bulk OTP programming is performed prior to final test, since OTP cannot be reprogrammed in-field. For designs that may need firmware updates or that require more than 128 bytes of data EEPROM, evaluate flash-based PIC16F counterparts (PIC16F627A, PIC16F628A, PIC16F88) as candidates.

The OTP architecture is appropriate here because appliance firmware is rarely updated after launch and the BOM cost is critical. The device's 3V to 5.5V supply is compatible with rectified 5V rails, while the 200ns instruction cycle is fast enough for motor-control loops driving TRIACs or relays through optocouplers. The 18-pin SOIC package supports compact PCB designs, and the industrial -40C to +85C rating covers the kitchen and laundry environment. Engineers typically pair the PIC16CE623 with the PIC16F628A as a fall-back for serviceability.

Wichtigste Unterscheidungsmerkmale
- Integrated 128-byte EEPROM for non-volatile data storage (vs. PIC16CE623-04I/SO (same family but no "T"))
- Industrial -40C to +85C temperature rating (vs. PIC16CE623T-04/SO (commercial 0C to +70C))

Designhinweise
Estimated: at 4MHz and 5V supply, the PIC16CE623T-04I/SO core typically draws 2 to 5 mA active and < 5 uA in sleep mode per Microchip datasheet. Place a 100nF decoupling capacitor directly between VDD (pin 18) and VSS (pin 17), with traces kept short to minimize supply noise. For battery-powered designs, leverage the SLEEP instruction and use the watchdog timer or external interrupt to wake, reducing average current to microamp levels. Bulk 10uF capacitance near the supply rail improves transient response when driving LEDs or relays through port pins.
The PIC16CE623T-04I/SO uses OTP (One-Time Programmable) program memory, which cannot be erased or rewritten after programming. Ensure firmware is fully validated before committing to OTP programming; debugging should be done with a windowed PIC16C623 or a flash-based PIC16F628A substitute. Pin 1 (MCLR/VPP) is shared between reset and programming voltage, so the in-circuit programming header must isolate VPP from the reset pull-up. Do not exceed 13.5V on MCLR/VPP during programming or the device will be damaged.
Keep the external crystal or resonator traces between OSC1 (pin 7) and OSC2 (pin 8) short and symmetrical to minimize EMI and oscillator distortion. Place the crystal loading capacitors (typically 15 to 22 pF) within 5 mm of the oscillator pins. Avoid routing high-speed digital signals (RC port toggling) parallel to OSC1/OSC2, and keep analog inputs (RA0-RA3) away from digital switching pins. Use a ground pour under the MCU and route VDD with a wide trace or small power plane to reduce inductance.
