PIC16CE623T-30/SS Visão geral
An EPROM-based 8-bit MCU (microcontroller) is a single-chip computer that integrates CPU, EPROM program memory, RAM, EEPROM data memory, and peripherals onto one CMOS die. EPROM (Erasable Programmable Read-Only Memory) allows the program to be erased via UV exposure and re-programmed, making these parts popular for prototyping and low-volume production. Within the taxonomy, PIC16CE62x devices sit under: MCU -> 8-bit microcontroller -> PIC16 family -> PIC16CE62x sub-family -> PICmicro EPROM-based.
Key features include 35 single-cycle instructions (program branches are two-cycle), an internal 4 MHz RC oscillator option, power-on reset (POR), brown-out reset (BOR), a watchdog timer (WDT) with its own on-chip RC oscillator, and low-power SLEEP mode. The PIC16CE623 uses a Harvard architecture with a 14-bit instruction word, providing code density advantages over competing 8-bit CISC architectures. The integrated 96-byte EEPROM enables data parameter storage without external NVRAM, and 13 I/O pins support direct LED, switch, and low-speed peripheral interfacing.
The PIC16CE623T-30/SS is built on a fully-static CMOS process, consuming microamp-level current in SLEEP mode and a few milliamps active. The architecture supports an 8-level hardware stack and direct/indirect addressing modes. Interrupt sources include external RB0/INT, RB port-change, timer overflow, and EEPROM write completion. Combined with the 30 MHz clock headroom and deterministic instruction timing, the part is well-suited for closed-loop control applications that require predictable response latency.
Typical applications include consumer appliance controllers, simple sensor interfaces, low-cost remote-control transmitters, security keypads, and small motor/valve drivers. The 20-pin SSOP footprint and Microchip's standard PIC16 toolchain (MPLAB X IDE, MPASM, XC8 compilers) further accelerate development. Engineers selecting this part typically value the EPROM reprogrammability, integrated EEPROM data memory, and the mature PIC16 instruction set for time-to-market.
When designing with this device, ensure VDD decoupling is placed close to the pin with a 100 nF ceramic and 10 uF bulk capacitor, and observe the 30 MHz maximum clock input. For noise-critical applications, use the on-chip watchdog and brown-out reset to recover from voltage transients. Unlike PIC16F Flash variants, the EPROM die requires a quartz windowed package for erasure, which is why the T-30/SS variant is typically used for one-time-programmed production.

Aplicações típicas
PIC16CE623T-30/SS é adequado para 6 aplicaçãos: Consumer Appliance Controllers, Remote Control Transmitters, Security Keypad and Access Modules, Sensor Interface Modules, Small Motor and Valve Drivers, Automotive Interior Accessories.
Consumer Appliance Controllers
The PIC16CE623T-30/SS fits consumer appliance controllers because its 13 GPIO pins can directly drive relays, triacs, and seven-segment LED displays without external logic. The 96-byte on-chip data EEPROM stores user-set values such as wash cycle counts, temperature thresholds, and timer presets that persist across power cycles. With the 30 MHz instruction rate (200 ns per cycle), the firmware can scan a 4x4 keypad matrix, debounce inputs, and update PWM-driven outputs well within human-perceptible response windows. Brown-out reset and watchdog timer ensure recovery from mains transients or firmware lock-up, both critical in unattended household appliances where reliability is paramount for UL/IEC safety compliance.
Recomendado
Remote Control Transmitters
For low-cost IR/RF remote-control transmitters, the PIC16CE623T-30/SS offers exactly the right balance of low pin count, integrated oscillator, and SLEEP-mode current under 1 uA that extends coin-cell battery life to years. The 30 MHz CPU clock generates accurate 38 kHz carrier waveforms with cycle-perfect timing for NEC, RC5, or Sony IR protocols without dedicated hardware PWM peripherals. EPROM program memory locks the firmware against reverse engineering of proprietary protocols. The 13 GPIOs easily handle a 4x4 button matrix, status LED, and IR LED driver transistor. Brown-out reset prevents corrupted transmission during battery end-of-life voltage sag.
Recomendado
Security Keypad and Access Modules
The PIC16CE623T-30/SS is well suited for security keypad controllers that read PIN codes from a matrix keypad and drive a magnetic lock or buzzer. Its on-chip 96-byte EEPROM stores up to 50 user PINs or event log entries without external serial EEPROM, reducing BOM cost and PCB area. The 30 MHz clock scans a 12-key matrix in under 100 us while simultaneously debouncing contact noise and validating PIN length. Watchdog timer recovery protects against lock-up from intentional EMI tampering, a common attack vector on exposed keypads. The 20-pin SSOP footprint fits inside slim door-frame housings where Z-height is constrained.
Recomendado
Sensor Interface Modules
In low-speed sensor interface boards reading thermistors, photo-diodes, or moisture sensors, the PIC16CE623T-30/SS provides an integrated ADC alternative through its analog comparator plus software oversampling, eliminating external ADC ICs in simple designs. The 30 MHz instruction cycle supports 10-bit equivalent resolution at 1 kHz sample rates by averaging successive comparator thresholds. On-chip EEPROM logs calibration coefficients per sensor, allowing field-replaceable sensor modules without host reconfiguration. Brown-out reset and the watchdog timer handle automotive and industrial voltage transients, making this part appropriate for distributed sensor nodes in building-automation or agricultural monitoring networks.
Recomendado
Small Motor and Valve Drivers
Stepper motors and solenoid valves benefit from the deterministic 200 ns instruction cycle of the PIC16CE623T-30/SS, which produces jitter-free phase commutation at up to 30 MHz. The 13 GPIO pins can directly drive four Darlington pairs or power MOSFET gates for unipolar stepper control, or two H-bridges for bipolar DC motors. The integrated 16-bit Timer1 module provides the time base for software PWM at 50 Hz to 20 kHz, sufficient for DC motor speed control or proportional valve actuation. EPROM-based firmware lock prevents unauthorized parameter changes that could damage driven equipment.
Recomendado
Automotive Interior Accessories
Although not AEC-Q100 qualified, the PIC16CE623T-30/SS finds use in non-critical automotive interior accessories such as ambient lighting controllers, seat heaters, and convenience LED dimmers where its 3.0 V to 5.5 V supply range covers 12 V battery transients when paired with proper regulation. The integrated watchdog timer and brown-out reset satisfy OEM requirements for fault recovery, while the 30 MHz clock enables smooth 1 kHz PWM for flicker-free LED dimming. EPROM memory ensures the firmware cannot be tampered with via software reflashing, a security benefit for OEM-trademarked modules. The SSOP-20 footprint is small enough for inline wiring-harness modules.

Notas de projeto
Place a 100 nF ceramic decoupling capacitor as close as possible to the VDD pin (pin 20) of the PIC16CE623T-30/SS, plus a bulk 10 uF electrolytic or tantalum on the same supply trace. The EPROM program memory draws brief, high-current pulses during programming and execution bursts; insufficient decoupling can cause erratic instruction fetches and stack corruption. For battery applications, also place a 100 nF across the MCLR pin to filter voltage spikes that might otherwise trigger spurious resets during load-dump events.
Route the crystal traces (OSC1/OSC2, pins 15-16) short and symmetric, with the crystal case grounded to a quiet ground island. Keep the OSC traces away from high-current switching nodes (relay coils, motor phases) to avoid injecting oscillator jitter. If using the internal 4 MHz RC oscillator instead, leave OSC1 floating or tied to VDD and OSC2 as a general-purpose I/O to avoid stray pickup.
Estimated: configuration-word programming must be set for the chosen oscillator mode (HS for >4 MHz crystal, XT for <=4 MHz, RC for resistor-capacitor). Programming the wrong oscillator mode is the single most common bring-up failure on PIC16CE62x designs. Always configure the WDT (WDTE bit) intentionally - if disabled, firmware faults will hang the MCU indefinitely. Use ICD2/ICD3-compatible RB6/RB7 pins for in-circuit debug, but ensure no load capacitance >50 pF is placed on these pins during debug sessions.
