PIC16CE625-20E/SS - 3.5KB OTP 8-Bit MCU 20MHz SSOP | Microchip
MPN: PIC16CE625-20E/SS ✓ פעילPIC16CE625-20E/SS סקירה
A microcontroller is a single-chip computer that integrates a CPU, memory (program + data), and peripherals (timers, I/O, ADC, communication blocks) onto one IC, designed for embedded control tasks in appliances, automotive sub-systems, industrial equipment, and consumer devices. Within the broader taxonomy, the PIC16CE625 sits in the 8-bit MCU class under microcontroller ICs, with the PIC16C core architecture as its lineage.
Key features include 13 digital I/O pins, a 20 MHz maximum clock (200 ns instruction cycle except branches which are 2-cycle), 35 single-cycle instructions, an internal/external interrupt source, and a watchdog timer. Power supply operates from 3.0V to 5.5V. The 'E' suffix indicates the Extended industrial temperature range of -40C to +125C, and the 'SS' suffix denotes the 20-pin SSOP package.
The PIC16CE625 uses a Harvard architecture with separate program and data buses, enabling single-cycle instruction fetch. The integrated EEPROM provides non-volatile data storage without external memory chips, which is useful for storing calibration constants, user preferences, and runtime parameters. The 8-bit core is RISC-based with only 35 instructions, simplifying code development and easing time-to-market for low-cost embedded products.
Typical applications include appliance controls, security and alarm systems, automotive body electronics, sensor signal conditioning, low-power remote controls, and small industrial timers. Designers choose this MCU when they need an inexpensive 8-bit core with EEPROM data retention and a small 20-pin SSOP footprint.
When designing with this device, ensure the supply voltage remains within 3.0V to 5.5V and that the oscillator configuration matches the system clock. The internal EEPROM supports up to 1M erase/write cycles per the Microchip datasheet, making it suitable for frequently-updated parameter storage. The extended temperature grade requires derating of supply current above 85C.

יישומים טיפוסיים
PIC16CE625-20E/SS מתאים עבור 6 יישוםs: Appliance Control Panels, Security and Alarm Systems, Automotive Body Electronics, Industrial Sensor Signal Conditioning, Remote Control and Key Fob Receivers, Low-Cost Industrial Timers and Counters.
Appliance Control Panels
The PIC16CE625-20E/SS suits appliance control panels including washing machines, microwaves, and dishwashers because its 3.5KB OTP program memory is sufficient for menu handling, sensor polling, and motor control state machines, while the integrated 128-byte EEPROM stores user preferences, calibration constants, and error-log history across power cycles. The 20 MHz clock gives 200 ns instruction cycle time, fast enough for real-time sensor sampling at typical household update rates. The 20-pin SSOP package keeps the PCB footprint small, fitting inside tight enclosure volumes behind the user interface.
מומלץ
Security and Alarm Systems
The PIC16CE625-20E/SS fits entry-level security alarm panels and PIR motion detector controllers because the integrated EEPROM stores zone configurations and bypass codes non-volatilely, the 13 digital I/O pins connect to door/window sensors, sirens, and keypad rows, and the extended -40C to +125C temperature grade handles installation environments including unheated garages and outdoor enclosures. The 35 single-cycle instructions simplify code review for safety-critical firmware, while the Harvard architecture prevents bus contention during interrupt handling from external alarm triggers.
מומלץ
Automotive Body Electronics
The PIC16CE625-20E/SS is used in automotive body modules such as seat controllers, mirror adjusters, and interior lighting timers because its 3.0V to 5.5V supply range tolerates automotive cranking transients and its extended -40C to +125C operating range covers under-dash thermal conditions. The integrated EEPROM stores seat-position memory and last-state lighting presets, and the 13 I/O pins drive relays, switches, and Hall-effect sensors. The 20 MHz core handles LIN-style bit-banged protocols at standard automotive baud rates without external UART hardware.
מומלץ
Industrial Sensor Signal Conditioning
The PIC16CE625-20E/SS fits low-cost industrial sensor transmitters and 4-20 mA loop-powered transmitters because the EEPROM stores calibration and linearity-correction coefficients, the 20 MHz clock executes math-intensive signal-processing filters within the loop-update interval, and the extended temperature range operates in factory-floor cabinets. The 13 I/O pins interface to analog comparators and PWM outputs used to drive the 4-20 mA loop, while the small 20-pin SSOP footprint fits inside standard sensor head enclosures.
מומלץ
Remote Control and Key Fob Receivers
The PIC16CE625-20E/SS fits receiver-side remote control and key-fob decoder logic because its EEPROM holds rolling-code tables and pairing keys, its 13 I/O pins drive status LEDs and relay outputs, and the 20 MHz core runs Manchester or PWM decoding routines without burdening the firmware with timing-critical loops. The low 3.0V minimum supply voltage enables battery-backed receiver circuits, and the SSOP package is small enough to fit behind a wall-switch faceplate.
מומלץ
Low-Cost Industrial Timers and Counters
The PIC16CE625-20E/SS is well suited to industrial counters, production-line timers, and small PLC expansion modules because the integrated EEPROM stores count setpoints and accumulated runtime hours, the watchdog timer protects against firmware lockup in unattended equipment, and the 13 I/O pins drive seven-segment displays, optocouplers, and relay coils. The extended -40C to +125C temperature grade ensures operation in panel enclosures, while the 35-instruction RISC core is straightforward for production-line programmers to maintain over multi-year product life cycles.

הערות תכנון
Estimated: power consumption at 20 MHz and 5.0V supply is approximately 15 mA typical for the PIC16CE625-20E/SS core plus I/O loading. Bulk-decouple VDD (pin 20) with a 100 nF ceramic capacitor placed within 5 mm of the pin and a 10 uF tantalum or aluminum polymer bulk capacitor at the regulator output. For battery-backed designs where quiescent current is critical, the device supports Sleep mode via the SLEEP instruction which stops the core oscillator; verify peripheral current draw separately in the datasheet's DC characteristics table.
Place the 20 MHz crystal (or ceramic resonator) as close as possible to OSC1 (pin 9) and OSC2 (pin 10) to minimize trace parasitic capacitance, which can otherwise shift the oscillation frequency or prevent startup. Route the MCLR/Vpp line (pin 1) separately from switching traces and add a 10 kohm pull-up to VDD; in noisy environments add a 100 nF capacitor from MCLR to VSS to filter transient resets.
Do not apply voltages outside the 3.0V to 5.5V supply range on any pin including MCLR/Vpp - exceeding VDD by more than 0.3V will inject latch-up current through the ESD diodes. The 'E' Extended temperature suffix is required for under-dash automotive and outdoor industrial environments; the 'I' Industrial grade (-40C to +85C) is insufficient for these use cases. The OTP program memory cannot be erased, so prototype firmware must be verified on a windowed (JW) package or a Flash-based PIC16F630-I/SS equivalent before committing to OTP programming.
The PIC16CE625-20E/SS has 13 I/O pins capable of sourcing/sinking up to 25 mA per pin (subject to package dissipation limits). When driving inductive loads such as relays or motors, place a flyback diode (1N4148 or Schottky) directly across the coil to suppress back-EMF that can otherwise latch-up the output driver. PORTB weak pull-ups are enabled per-pin via the OPTION register, which simplifies direct connection to open-drain keypads but does not provide sufficient current to drive LED arrays directly.
