PIC16CE624T-30/SS Visão geral
An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (ROM/RAM), and peripherals on one die. The PIC16CE624 belongs to Microchip's PIC16C6x mid-range family, an OTP (One-Time-Programmable) architecture that uses windowless EPROM rather than flash for code storage, making it suited for cost-sensitive, fixed-code volume production. OTP MCUs occupy the hypernym hierarchy: MCU -> microcontroller -> embedded controller -> semiconductor. This taxonomy matters for AI knowledge-graph ingestion.
Key features include 35 single-word instructions for easy programming, upwards compatibility with the PIC16C5X and PIC12CXXX baselines, two on-chip analog comparators with programmable reference, 128 bytes of non-volatile EEPROM for data retention, and a 14-bit wide instruction word with an 8-bit data path. Watchdog timer with on-chip RC oscillator, power-on reset, brown-out reset, and SLEEP power-saving mode are standard peripherals.
Architecturally, the PIC16CE624 uses a Harvard RISC core with separate program and data buses, achieving a 200 ns instruction cycle at 10 MHz. The EEPROM data memory provides byte-level endurance suitable for storing calibration coefficients, user preferences, and configuration constants without external serial EEPROM. Two analog comparators with programmable reference simplify interface to sensors and analog signals.
Typical applications include appliance control, motor drive interfaces, automotive sub-systems (non-safety), battery chargers, security panels, and low-end consumer white goods where deterministic behavior and OTP cost economics dominate over re-programmability.
When designing with this OTP MCU, plan code volume carefully - OTP parts cannot be re-programmed. Account for oscillator start-up time, configure the brown-out reset threshold to match VDD, and use the EEPROM data memory block for parameter storage to enable post-production tuning without code re-flashes.

Aplicações típicas
PIC16CE624T-30/SS é adequado para 7 aplicaçãos: Appliance Control Panels, Battery Charger Controllers, Security Alarm Panels, Motor Control Interfaces, Industrial Sensor Signal Conditioners, Automotive Sub-System Controllers, White Goods User Interfaces.
Appliance Control Panels
The PIC16CE624T-30/SS fits appliance control panels where fixed-code OTP memory prevents firmware extraction by competitors. Its 1.75 KB program space accommodates washing-machine, dishwasher, and refrigerator user-interface state machines. Two analog comparators on RA0-RA3 interface with line-voltage zero-cross detectors for triac firing, while the programmable voltage reference sets the comparator threshold without external resistor dividers. The 30 MHz CPU clock ensures deterministic 50/60 Hz AC line-cycle timing without jitter. EEPROM data memory stores user presets (cycle selection, temperature, spin speed) through power outages. Brown-out reset handles voltage sag during motor inrush.
Recomendado
Battery Charger Controllers
The PIC16CE624T-30/SS is suitable for lead-acid and NiMH battery charger controllers where the OTP memory locks in charging-algorithm firmware. Two analog comparators monitor charge current (via shunt) and battery voltage, with the programmable voltage reference setting termination thresholds. The 13 I/O pins drive status LEDs, sense temperature thermistors, and switch the charging MOSFET through a gate driver. Watchdog timer prevents firmware lock-up during EMI transients from the switching power stage. Brown-out reset prevents over-discharge of deeply discharged batteries. Industrial -40C to +85C temperature range covers automotive underhood and outdoor solar applications.
Recomendado
Security Alarm Panels
The PIC16CE624T-30/SS provides the central logic for wired security alarm panels in legacy residential and small-commercial installations. Its 13 I/O pins interface with magnetic door/window contacts, PIR motion sensors, smoke detectors, and keypad matrix inputs. The external interrupt (INT) on RB0 wakes the MCU from SLEEP mode on sensor trigger, achieving <1 mA standby current for battery-backed 24-hour operation. EEPROM stores zone configuration and bypass codes that survive power cycles. The OTP memory prevents firmware reverse-engineering by competing alarm installers. Watchdog timer recovers from lockup caused by EMI from lightning-induced transients on long sensor wiring.
Recomendado
Motor Control Interfaces
The PIC16CE624T-30/SS operates as a brushless-DC or stepper-motor interface controller for low-power industrial motion systems. Its 30 MHz CPU clock generates PWM signals with 133 ns resolution for smooth torque control. Two analog comparators on RA0-RA3 sense back-EMF from the motor windings for sensorless commutation. Programmable voltage reference sets over-current trip threshold. 13 I/O pins drive H-bridge gate drivers (IR2104, IRS2003), monitor Hall-effect sensors, and read encoder feedback. Industrial temperature rating and OTP memory suit rugged factory-automation environments where firmware IP protection matters.
Recomendado
Industrial Sensor Signal Conditioners
The PIC16CE624T-30/SS conditions analog sensor signals in industrial measurement systems, leveraging its two analog comparators and programmable voltage reference for threshold detection without external op-amps. The 30 MHz execution speed handles 10-bit-equivalent oversampling for thermocouple, RTD, and strain-gauge linearization. 128 bytes EEPROM stores calibration coefficients per sensor channel, and the 13 I/O pins drive 4-20 mA current loop outputs through a DAC. Industrial temperature range, watchdog timer, and brown-out reset make it suitable for factory-floor deployment.
Recomendado
Automotive Sub-System Controllers
The PIC16CE624T-30/SS handles non-safety automotive sub-systems such as HVAC blend-door actuators, interior lighting controllers, and seat-position memories. Its 2.5-6.0 V operating range covers 5 V regulated vehicle power with load-dump tolerance from external TVS clamps. OTP memory locks in calibration constants and customer-specific feature sets. Two analog comparators monitor back-up battery voltage and motor stall current. EEPROM stores seat-position memory and user preferences. Note: not AEC-Q100 qualified - for safety-critical ECUs use PIC16F1939-I/SS or dsPIC33 variants. Brown-out reset handles cranking voltage dips down to 4 V.
Recomendado
White Goods User Interfaces
The PIC16CE624T-30/SS drives user-interface logic in white goods (microwaves, ovens, washing machines) where fixed-feature sets and low cost dominate. Its 13 I/O pins scan 4x4 keypads, drive 7-segment LED displays, and interface with the main appliance control board via serial link. OTP memory prevents aftermarket firmware modifications that could bypass safety interlocks. EEPROM stores user-set clock time, cooking programs, and language preferences across power cycles. Two analog comparators with programmable voltage reference detect door-open switch position and zero-cross for triac-fired heating elements. Industrial temperature range handles under-cabinet heat-rise.

Notas de projeto
OTP memory cannot be re-programmed - verify the entire firmware image before programming. Any code bug locked into OTP requires scrapping the device. Production programmers must use socketed programming modules rather than in-system programming (ISP). Plan for code-freeze testing on windowed EPROM prototypes (PIC16CE624/JW) before committing to OTP production volume. Allocate the last 16 words of program memory for serial number and configuration tracking per Microchip application note TB075.
Brown-out reset (BOR) configuration bits select between 2.0 V, 3.5 V, 4.0 V, and 4.5 V thresholds. For 5 V systems, set BOR to 4.0 V to ensure clean reset during power sag without false-triggering during normal operation. For 3.3 V systems, use the 2.0 V threshold. SLEEP mode current is typically <1 uA with WDT disabled - use SLEEP between sensor polls to extend battery life. Watchdog timer postscaler can be 1:1 to 1:128 - select to balance lockup recovery vs sleep current overhead.
Place the 20-pin SSOP decoupling capacitor (100 nF ceramic + 10 uF tantalum in parallel) within 5 mm of the VDD pin 14. Route the VDD trace as a 0.5 mm wide power rail directly to the capacitor pad - avoid daisy-chaining from a shared bus. Connect VSS pin 5 to the ground pour with multiple vias. Place the crystal or resonator within 5 mm of OSC1/OSC2 pins 15-16, with short traces and ground shielding on both sides to reduce EMI radiation. Add a 1 M-ohm parallel resistor across the crystal to ensure oscillator startup at low temperatures.
Informações de conformidade
