PIC16CE625T-04/SS - 4MHz 8-bit MCU 3.5KB OTP 128B EEPROM | Microchip
MPN: PIC16CE625T-04/SS ✓ فعالPIC16CE625T-04/SS جائزہ
An 8-bit microcontroller (MCU) is a small, self-contained computing device built around an 8-bit data path, integrating a CPU, non-volatile program memory, working RAM, and configurable peripherals on a single CMOS die. The PIC16CE62X series belongs to the broader mid-range PIC microcontroller family, which sits inside Microchip's PIC -> RISC microcontroller -> embedded controller -> semiconductor taxonomy. The 'CE' suffix indicates the addition of on-chip EEPROM data memory that retains user data even when the device is powered down, distinguishing the 'CE' line from the standard OTP-only 'C' parts.
Key features of the PIC16CE625T-04/SS include a 13-bit instruction word with 14-bit wide opcode, an internal 8-level hardware stack, two 8-bit timers (Timer0 and Timer2) plus one 16-bit timer (Timer1), a 10-bit multi-channel analog-to-digital converter, and 13 digital I/O pins capable of driving 25mA source/sink for direct LED interface. The device supports in-circuit serial programming (ICSP) via two pins, enabling firmware updates after PCB assembly.
The architecture uses a Harvard-style separated program/data bus and a RISC-style single-cycle instruction pipeline (except program branches, which require two cycles). Its 35-instruction set maps directly to one opcode each, simplifying compiler and assembler design. The integrated 128-byte EEPROM supports 1 million erase/write cycles minimum and 40-year retention, suitable for storing calibration, configuration, or user preference data.
Typical applications include appliance control front-panels, low-cost sensor interface nodes, automotive body controllers, lighting ballasts, and small consumer devices requiring non-volatile parameter storage. The wide 3.0V-5.5V supply range allows operation directly from a 3.3V regulator or from a regulated 5V rail. Design considerations include careful PCB layout for the analog VREF pin when using the ADC, and ensuring the MCLR reset pin has a proper RC network to avoid spurious resets in noisy environments.

عام استعمالات
PIC16CE625T-04/SS کے لیے موزوں ہے 6 ایپلیکیشنs: Appliance Control Front-Panels, Automotive Body Electronics, Lighting Ballast Controllers, Low-Cost Sensor Interface Nodes, Consumer Remote Controls and IR Transmitters, Battery Chargers and Power Management.
Appliance Control Front-Panels
The PIC16CE625T-04/SS suits appliance front-panel controllers (washing machines, microwave ovens, dishwashers) where 13 GPIO pins drive 7-segment displays, keypads, and relay coils directly at 25 mA per pin. Its 3.5 KB OTP accommodates typical state-machine control firmware while the 128-byte EEPROM stores user-selectable wash cycles, language preferences, and last-used settings across power cycles. Operating from 3.0 V to 5.5 V lets the same PCB work with either a 3.3 V logic supply or a regulated 5 V rail.

Automotive Body Electronics
The PIC16CE625T-04/SS (commercial grade) and its industrial sibling PIC16CE625T-04I/SS handle body-control tasks such as interior lighting dimming, mirror position memory, and seat control. The integrated 128-byte EEPROM preserves mirror and seat positions even when the battery is disconnected for service, while the 13 I/O pins interface directly to H-bridge drivers and switch matrices. For under-hood modules requiring -40 C to +125 C operation, the PIC16CE625T-04E/SS extended-temperature variant is pin-compatible.

Lighting Ballast Controllers
Ballast controllers for fluorescent, LED, and HID lighting benefit from the PIC16CE625T-04/SS combination of timer peripherals and 13 I/O. Timer1 (16-bit) generates precise PFC switching frequencies while the 8-bit Timer2 handles dimming PWM duty-cycle control. The 128-byte EEPROM stores calibrated trim values for lamp current sensing, compensating for component tolerance drift across production batches. The 4 MHz clock is sufficient for low-frequency ballast control loops under 1 kHz bandwidth.

Low-Cost Sensor Interface Nodes
Industrial sensor interfaces (temperature, humidity, pressure transducers with analog outputs) pair well with the PIC16CE625T-04/SS, which provides ADC input channels, EEPROM for calibration constants, and ICSP for factory-side firmware updates. The 128-byte EEPROM stores per-unit calibration coefficients that compensate for sensor tolerances, while 128 bytes of RAM buffer sample averaging. Sleep-mode current and the 3.0 V minimum supply enable battery or energy-harvest powered operation.

Consumer Remote Controls and IR Transmitters
Handheld remote controls benefit from the PIC16CE625T-04/SS's small SSOP-20 footprint, low 3.0 V minimum supply, and EEPROM for storing learned IR codes. The 13 GPIO pins drive IR LEDs directly at 25 mA while reading matrix keypads; the 128-byte EEPROM retains user-programmed button mappings across battery swaps. The PIC16CE624T-04/SS serves as a cost-down for simpler fixed-code remotes that need only 1.75 KB of firmware space.

Battery Chargers and Power Management
Simple sealed-lead-acid (SLA) and NiMH charger controllers use the PIC16CE625T-04/SS to implement CC/CV charge profiles with EEPROM storage of charging parameters. The 13 I/O pins interface to MOSFET gate drivers, current-sense amplifiers, and status LEDs; the 128-byte EEPROM stores per-battery-pack capacity, last-charge time, and cycle count. The 200 ns instruction cycle is fast enough for closed-loop current regulation in sub-100 kHz PWM designs.

ڈیزائن نوٹس
Place a 0.1 uF decoupling capacitor as close as possible to the Vdd pin (pin 14) and a bulk capacitor (4.7 uF to 10 uF) at the regulator output. The PIC16CE625T-04/SS draws sub-mA active current and only microamps in sleep, but the ADC reference (VREF+/VREF-) pins benefit from additional filtering capacitors when used. Estimated: typical Vdd current at 4 MHz, 5 V is approximately 2 mA active and 1 uA sleep per the PIC16CE62X family characteristics.
The MCLR pin (RA5/MCLR/VPP) is shared between GPIO, master clear reset, and programming voltage input. If used as a GPIO, ensure the ICSP programmer does not drive high voltage during normal operation, or use a diode isolation scheme. A weak pull-up (typically 10 kohm) on MCLR is required for normal reset behavior; without it, the part may enter unpredictable reset states in noisy environments. Never leave MCLR floating.
The SSOP-20 package has a 0.65 mm pin pitch, requiring PCB pads of approximately 0.40 mm width with 0.20 mm spacing - well within standard 4-mil/8-mil SMT fabrication capabilities. Use a ground plane beneath the device and keep high-speed switching traces (crystal, oscillator) short and surrounded by ground. Crystal traces should be < 5 mm each to minimize parasitic capacitance and ensure reliable oscillator startup across the full 3.0 V to 5.5 V supply range.
