PIC24F04KA200-I/P - 16-Bit 32MHz XLP MCU | Microchip
MPN： PIC24F04KA200-I/P ✓ 啟用中PIC24F04KA200-I/P 概覽
A microcontroller is a programmable system-on-chip that combines a CPU core, memory, digital I/O, timers, and peripherals in one integrated circuit. The PIC24F04KA200 device is positioned as a low-power embedded controller within the broader hierarchy of microcontroller, embedded processor, and semiconductor. Its 10-bit ADC supports analog measurement, while the listed CTMU and UART peripherals support touch-capacitive measurement and serial communication.
Key verified specifications include 16-bit instruction architecture, 32 MHz maximum frequency, 4 KB Flash organized as 1.375K × 24 words, 512 bytes of RAM, 12 I/O pins, and operation from a 3 V supply as identified in the distributor listings. The ADC is listed at 10 bits and 500 ksps conversion performance. XLP power-management features include DSBOR deep-sleep operation, DSWDT, and the RTCC peripheral.
The -I/P ordering identifies Microchip's industrial-temperature 14-pin PDIP configuration. The /P package is a through-hole 14-DIP format measuring 0.300 inch wide and 7.62 mm across the pin row. It is appropriate for prototypes, instruments, controllers, and educational platforms where through-hole assembly and easy inspection are preferred. Exact pin functions, voltage limits, and full timing boundaries must be confirmed in the manufacturer documentation.
Typical uses include battery-powered sensing, compact industrial controls, digital thermometers, capacitive-touch interfaces, low-power data loggers, and embedded instruments. The 500 ksps ADC can sample changing analog inputs quickly, while the UART supports a straightforward serial link to another controller or host. Designers should use the XLP modes aggressively rather than leaving the MCU active continuously when the application spends most of its time waiting.
For low-power design, activate a suitable sleep mode between measurements, disable unused peripherals, and choose wake sources that match the required response time. The PCB should provide clean decoupling near the supply pins and adequate signal-routing margins for analog measurements. Firmware and peripheral configuration must follow Microchip's PIC24F device documentation.
This page consolidates verified distributor specifications, manufacturer-series features, sourcing links, and design guidance. Pricing, lifecycle-sensitive fields, complete pin assignments, and absolute electrical limits are explicitly separated where the supplied search evidence does not establish them, preventing unsupported substitution during component selection.

典型應用
PIC24F04KA200-I/P 適用於 6 應用s: Battery-Powered Sensor Node, Capacitive-Touch Control Panel, Digital Thermometer, Low-Power Data Logger, Compact Industrial Control Module, UART-Based Monitoring Device.
Battery-Powered Sensor Node
PIC24F04KA200-I/P fits compact battery-powered sensing because its PIC24F04KA200 core combines a 32 MHz maximum clock with XLP-focused low-power features. DSBOR deep sleep can reduce consumption between samples, while DSWDT supports watchdog-based protection during active intervals. The 10-bit, 500 ksps ADC is useful for rapid sensor readings, and 512 bytes of RAM can hold current samples and control state. Firmware should wake on demand, perform a short conversion, transmit the result, and return to sleep to maximize battery life.
推薦
Capacitive-Touch Control Panel
The PIC24F04KA200-I/P can serve as the controller for a small capacitive-touch interface because the verified device family includes CTMU alongside the 10-bit ADC. CTMU-assisted measurement can evaluate touch or sensing behavior while the 32 MHz processor handles debouncing, filtering, and user-interface logic. Twelve I/O pins leave practical space for LEDs, indicators, and communication signals. Keep analog and touch traces short, provide stable grounding, and validate timing against the manufacturer’s CTMU guidance before production.
推薦
Digital Thermometer
PIC24F04KA200-I/P is appropriate for a digital thermometer that must balance acquisition speed with low standby demand. Its 10-bit ADC is listed at up to 500 ksps, allowing the firmware to acquire and average a sensor signal quickly before entering a low-power mode. The 512-byte RAM is sufficient for calibration values, filtered samples, and display-state variables, while the 32 MHz maximum clock supports responsive keypad and display updates. Accuracy will depend on reference quality, sensor conditioning, calibration, and board-layout noise control.
推薦
Low-Power Data Logger
The MCU fits an intermittent data logger that records sensor readings and stores or forwards them through a serial link. Its 4 KB Flash provides room for a compact program, 512 bytes of RAM supports buffering and state management, and the UART permits connection to a host or external nonvolatile storage controller. DSBOR can reduce power between record cycles, but Flash endurance and logging frequency must be managed carefully. The 14-PDIP package also simplifies assembly and rework in prototype instruments.
推薦
Compact Industrial Control Module
PIC24F04KA200-I/P can serve as the central controller in a compact industrial module with analog monitoring and serial diagnostics. The industrial -I/P ordering context, 12 I/O pins, and 32 MHz maximum clock are useful for coordinating inputs, control outputs, and UART-based service communication. Because the 4 KB Flash and 512-byte RAM are modest, the application should use interrupt-driven peripherals and avoid blocking software delays. Validate industrial temperature limits and transient immunity in the intended enclosure before release.
推薦
UART-Based Monitoring Device
PIC24F04KA200-I/P is suitable for a small remote-monitoring device when a UART link and periodic analog measurements are required. Firmware can service serial commands, acquire a 10-bit ADC channel at up to 500 ksps, filter the value, and transmit the result while DSBOR and DSWDT manage low-power and reliability requirements. The microcontroller’s limited memory favors short receive buffers and compact message formats. Use a defined UART baud rate and verify timing, framing, and logic levels with the connected host or transceiver.

主要差異化特點
- Low-power integration (對比Generic 16-bit microcontroller selections without verified XLP support)
- Through-hole assembly option (對比PIC24F04KA200-I/ST)
- Compact analog and serial resource set (對比Smaller-memory basic-control MCU options)
設計說明
Use the PIC24F04KA200 XLP facilities as part of the system architecture, not merely as firmware options. Place the device in an appropriate sleep mode during long idle intervals, disable unused peripherals, and select wake events deliberately. DSBOR, DSWDT, and RTCC are identified as low-power features, but actual current and wake latency must be measured under the intended clock, pin, and peripheral configuration.
Place required bypass capacitors close to the supply and ground pins and keep analog-sensor traces short, away from fast digital switching paths. The 14-PDIP footprint eases probing, but signal integrity still depends on grounding and trace routing. Confirm decoupling values, analog-reference requirements, exposed-pin connections, and maximum supply limits in the manufacturer datasheet before layout release.
Do not treat the similarly named PIC24F04KA200-I/ST as a mechanical substitute for the -I/P part. The verified listings identify 14-TSSOP for the -I/ST ordering and 14-PDIP for the target, so a PCB redesign is required. Also avoid assuming that a 32 MHz CPU rating permits a 32 MHz bus or peripheral clock; follow the family clock, timing, and voltage configuration rules from Microchip.
For the 10-bit, 500 ksps ADC, control source impedance, acquisition time, grounding, and reference stability. Average or oversample readings when greater effective resolution is required, but do not treat oversampling as a substitute for a clean analog front end. The supplied evidence establishes converter capability, not application accuracy, so calibrate the complete measurement path.
合規資訊
The supplied evidence does not state compliance for the exact PIC24F04KA200-I/P order code. AEC-Q100 is not applicable because this is an industrial microcontroller rather than an automotive-qualified claim in the supplied data.
