PIC16CE624-04I/SS - 8-bit OTP MCU, 4MHz, 1.75KB | Microchip

An 8-bit microcontroller (MCU) is a single-chip computer that integrates a CPU, program memory, RAM, non-volatile data memory and peripherals. PICmicro mid-range MCUs use a RISC core with only 35 single-word instructions and a Harvard architecture, simplifying firmware development while delivering deterministic interrupt response and predictable timing for real-time control.
Key features include two on-chip analog comparators, a programmable voltage reference, a 16-bit timer/counter with a programmable prescaler, an 8-bit timer/counter, a Watchdog Timer with its own on-chip RC oscillator for reliable resets, and brown-out reset protection. The internal 4 MHz oscillator option (selected by the /04 speed suffix) eliminates external crystal cost in space-constrained designs, while the industrial temperature grade (-40C to +85C, denoted by the /I suffix) enables harsh-environment deployment.
Architecturally, the PIC16CE624 separates program and data buses and executes most instructions in a single cycle. The integrated 128-byte EEPROM provides byte-level endurance of 10^6 write cycles typical, removing external NVM and shrinking BOM cost. The enhanced mid-range core supports hardware interrupts with prioritized vectors and an 8-deep hardware stack for efficient C and assembly coding.
Typical applications include appliance controllers, sensor signal conditioning, low-power remote controls, automotive body electronics subsystems, white goods user interfaces, and battery management front-ends. Designers also use it in industrial sensor transmitters, HVAC damper actuators, and small motor control loops where deterministic timing and EEPROM-backed parameter storage are required.
Designers should plan I/O mapping early: 13 of the 18 functional pins are available as GPIO while several share functions with the comparators, timer clock inputs, and the MCLR reset pin. A bulk-decoupling capacitor within 5 mm of VDD and a 10 kohm pull-up on MCLR are recommended for robust in-circuit programming and reset behavior.

典型應用
PIC16CE624-04I/SS 適用於 6 應用s: Appliance Control Boards, Sensor Signal Conditioning, Battery-Powered Remote Controls, HVAC Damper and Valve Actuators, Industrial Sensor Transmitters, User Interface Panels.
Appliance Control Boards
The PIC16CE624-04I/SS fits appliance controllers (washing machines, dishwashers, microwave ovens) thanks to its 13 GPIO pins for keypad and relay drivers, two comparators for line-voltage zero-cross sensing, and 128-byte EEPROM for storing user presets across power cycles. Operating from 3.0-5.5 V and at industrial -40C to +85C temperature range, the part survives kitchen and laundry thermal stress. The internal 4 MHz oscillator eliminates external crystal cost on BOM-sensitive white goods. Estimated program memory at 1.75 KB holds typical wash-cycle state machines with capacity to spare for diagnostic routines, while brown-out reset protects against brown-outs from motor inrush.
推薦
Sensor Signal Conditioning
The PIC16CE624-04I/SS handles sensor signal conditioning for thermocouples, RTDs, and pressure transducers by leveraging its two on-chip analog comparators and programmable voltage reference. The 16-bit timer/counter with programmable prescaler enables precise pulse-width measurement for flow sensors, while 96 bytes of SRAM accommodates running averages and linearization tables. With 3.0 V minimum supply, it powers directly from 3.3 V regulated rails common in modern sensor transmitters. The integrated Watchdog Timer with dedicated RC oscillator resets the MCU if firmware locks up due to EMI from nearby motor or relay switching, critical for unattended industrial installations.
推薦
Battery-Powered Remote Controls
For handheld remote controls and battery-powered key fobs, the PIC16CE624-04I/SS delivers low sleep current and 3.0 V minimum operation that lets designers use a single CR2032 or 2xAA cell stack. The 128-byte EEPROM stores paired device addresses and user preferences without external NVM. The internal 4 MHz oscillator option eliminates the external crystal cost and start-up delay, providing instant wake from sleep via the Watchdog Timer interrupt. Brown-out reset reliably detects end-of-battery voltage and preserves data. Per-packet current consumption is dominated by the radio companion chip, while the MCU contribution remains negligible, suiting months-long battery life requirements.
推薦
HVAC Damper and Valve Actuators
Building HVAC damper and valve actuator designs benefit from the PIC16CE624-04I/SS industrial temperature rating and on-chip peripherals for closed-loop control. The 16-bit timer/counter captures tachometer feedback from DC brushless motor drivers, while the two comparators sense motor overcurrent events for protection. The 128-byte EEPROM retains last-position setpoints across power cycles so actuators return to safe states on restoration. The 13 GPIO pins directly drive H-bridge logic and end-switch inputs. Operating from 3.0-5.5 V accepts 3.3 V regulated supplies from common HVAC bus converters without additional level shifting.
推薦
Industrial Sensor Transmitters
Industrial 4-20 mA loop-powered sensor transmitters leverage the PIC16CE624-04I/SS low voltage operation and wide industrial temperature range. The two analog comparators and programmable voltage reference provide excitation current measurement for RTD or thermocouple bridges without external op-amps. The 128-byte EEPROM stores calibration coefficients that survive factory programming and field re-calibration. Brown-out reset prevents erroneous 4-20 mA signaling during unstable loop voltage during plant start-up. The 1.75 KB program memory holds linearization routines for common sensor types. The internal 4 MHz oscillator eliminates external crystal in vibration-prone mounting locations.
推薦
User Interface Panels
User interface panels for white goods, security keypads, and small industrial HMIs benefit from the PIC16CE624-04I/SS combination of 13 GPIO pins for matrix keypads and LED indicators. The 16-bit timer/counter scans 4x4 keypads while the 8-bit timer generates LED PWM dimming. The 128-byte EEPROM stores user codes and configuration. Brown-out reset prevents corrupted NVM writes during unexpected power loss, a critical feature for security applications. Operating from 3.0-5.5 V supports both 3.3 V and 5 V backlight driver rails, while industrial -40C to +85C rating handles outdoor installations including garage door openers and access control panels.

設計說明
Place a 100 nF ceramic decoupling capacitor within 5 mm of the VDD pin (pin 14) and a 10 uF bulk capacitor on the same supply rail. Brown-out reset (BOR) holds the MCU in reset when VDD drops below the BOR threshold (typically 4.0 V at 5 V operation); configure the BOREN bit to enable this protection. For battery applications below 4 V, ensure VDD stays above 3.0 V minimum or the MCU enters undefined state.
Route the MCLR/VPP pin (pin 4) with a 10 kohm pull-up resistor to VDD to enable in-circuit serial programming (ICSP). For SSOP-20 layout, maintain at least 0.2 mm clearance between traces and a continuous ground pour under the IC body. Estimated: with a 4-layer PCB and 1 oz copper, the SSOP-20 thermal pad area (no exposed pad) yields theta_JA around 90 C/W which is sufficient given the low operating current (~5 mA active, <1 uA sleep).
Do not assume 13 I/O pins are all bidirectional without configuration; RA4 is open-drain and requires an external pull-up for high-side driving. The Watchdog Timer must be explicitly disabled in configuration fuses if unused, or it will reset the MCU unexpectedly. Configuration word (0x2007) must be set correctly before code execution or it defaults to unprogrammed state with internal RC oscillator selected. Note that OTP memory cannot be erased - verify firmware in development on a PIC16F version before final OTP programming.
