PIC24FV32KA304-I/PT - 32MHz 16-Bit XLP MCU | Microchip
MPN: PIC24FV32KA304-I/PT ✓ ActivePIC24FV32KA304-I/PT Overview
An XLP microcontroller is a Microchip low-power design category intended to reduce energy consumption during sleep, idle, and active operation. The PIC24FV32KA304 family combines a 16-bit CPU, flash memory, EEPROM, analog conversion, timing, and communication peripherals on one device. Its architecture sits within the hierarchy of 8-bit/16-bit microcontroller, embedded controller, and semiconductor product.
Key features include 32 KB of flash organized as 11K x 24 words, 512 bytes of EEPROM, a 12-bit ADC, CTMU support, and up to 16 MIPS instruction throughput according to the Microchip datasheet. The family also provides DSBOR, DSWDT, and RTCC peripherals that can operate during Deep Sleep, supporting designs that must preserve state or monitor time while consuming little power.
The enhanced PIC24 architecture supports a broad collection of peripherals for embedded control, while the 44-pin TQFP package provides access to digital I/O, analog inputs, oscillator connections, programming interfaces, and power pins. The -I/PT ordering code identifies an industrial-temperature, tray-packaged configuration according to the product listings and Microchip family documentation.
Typical uses include battery-powered sensor nodes, industrial condition-monitoring equipment, building and access controls, compact instrumentation, low-power data loggers, and embedded motor or actuator controllers. Its 12-bit ADC supports analog measurement, while CTMU can assist with capacitance-based sensing and resistive measurement applications.
Designers should preserve the XLP clock, reset, brownout, and peripheral arrangements shown in the manufacturer pin-description table. Firmware should use the DSBOR and DSWDT functions deliberately, maintain valid decoupling near the supply pins, and verify that the PCB footprint matches the 44-pin TQFP dimensions before releasing a layout.
This page combines the Microchip family datasheet, exact package and memory characteristics, low-power application guidance, sourcing instructions, and verified drop-in comparison information to support faster engineering selection and PCB planning.

Typical Applications
PIC24FV32KA304-I/PT is suitable for 6 applications: Battery-Powered Sensor Nodes, Industrial Condition Monitoring, Building Access and Security Controls, Capacitive-Touch Sensing, Compact Data Loggers, Embedded Motor and Actuator Control.
Battery-Powered Sensor Nodes
The PIC24FV32KA304-I/PT fits autonomous sensor nodes because it combines a 32 MHz 16-bit CPU with 32 KB flash, 2 KB RAM, and a 12-bit ADC while retaining low-power Deep Sleep functions. Its DSBOR, DSWDT, and RTCC peripherals can support brownout handling, watchdog supervision, and timekeeping when the main application is inactive. Place the MCU beside the sensor front end, use the ADC for analog measurements, and configure firmware to keep nonessential peripherals disabled during sleep. The principal design benefit is control functionality in a compact 44-pin TQFP without requiring a separate low-power supervisor.
Recommended
Industrial Condition Monitoring
The PIC24FV32KA304-I/PT is appropriate for industrial condition-monitoring equipment that records vibration, temperature, pressure, or analog process signals. Its 12-bit ADC supports analog sensor conditioning, while 16 MIPS instruction throughput provides enough response for sampling, filtering, threshold evaluation, and local control. The -I/PT ordering code is associated with industrial-temperature operation and tray packaging, allowing an assembler to receive the device in a standard manufacturing format. Keep analog and digital return paths separated, provide local bypass capacitance, and use the watch-dog facilities for unattended equipment.
Recommended
Building Access and Security Controls
The PIC24FV32KA304-I/PT can manage door contacts, keypads, lock drivers, status indicators, and communication interfaces in a low-power access-control panel. The 16-bit architecture supports deterministic control of multiple digital inputs and outputs, and the 32 KB flash provides room for protocol and application logic. A 12-bit ADC is also available for analog supervisory channels. For battery-backed installations, configure Deep Sleep between activity periods and retain RTC information where required. Validate timing margins for motor-driven locks and use isolation or suitable drive transistors rather than loading control pins directly.
Recommended
Capacitive-Touch Sensing
The PIC24FV32KA304-I/PT supports capacitive-touch and resistive-measurement designs through its CTMU capability. It can excite a sensor element, measure the resulting response, and apply filtering or threshold logic while retaining the general-purpose resources of a 32 MHz 16-bit microcontroller. The 44-pin TQFP package provides a practical number of I/O and analog connections for compact user-interface boards. Keep sensing traces short, isolate them from switching nodes, and follow the reference layout in the manufacturer datasheet. Calibrate each electrode in its final enclosure because mechanical assembly and grounding materially affect capacitance readings.
Recommended
Compact Data Loggers
The PIC24FV32KA304-I/PT is suitable for compact autonomous data loggers that periodically sample sensors and preserve operating state between measurements. Its 32 KB flash stores firmware and buffered records, 2 KB RAM supports active processing, and 512 bytes EEPROM retains configuration values without frequent flash writes. The DSBOR, DSWDT, and RTCC features assist with robust low-duty-cycle operation and timing. Design the scheduler around a low-power wake event, avoid leaving the ADC continuously active, and use brownout detection to distinguish deliberate shutdown from an unexpected supply interruption.
Recommended
Embedded Motor and Actuator Control
The PIC24FV32KA304-I/PT can serve as the supervisory controller in a low-voltage motor, valve, or actuator system. Its 32 MHz clock and 16 MIPS throughput support timely state-machine control, while the ADC can monitor a feedback signal and the 44-pin package offers a practical interface for pulse sensors, status LEDs, and driver commands. Use timer outputs or software timing for the required control interval and add suitable transistor drive and protection components. Brownout and watchdog functions improve recovery behavior, but the final motor circuit must be validated for back-EMF, inrush current, and thermal limits.

Design Notes
Configure the firmware around the device's XLP sleep modes and keep the ADC, timers, and communication peripherals disabled when they are not required. DSBOR, DSWDT, and RTCC can remain useful during Deep Sleep, but their operating behavior and wake conditions must be confirmed in the Microchip PIC24FV32KA304 family data sheet 30009995e. Use a supply regulator and decoupling arrangement that remains stable across the full sleep-to-active transition.
Assign every connection using the 44-pin TQFP pin-description table in the manufacturer documentation, including programming, clock, reset, analog, and supply pins. Preserve the exposed package geometry and lead pitch specified for the 10 x 10 mm TQFP, and provide adequate solderable area without extending copper into the component body. Place input and bulk-decoupling capacitors close to their associated supply pins to limit transient current loops.
Route sensitive analog inputs away from switching nodes, high-current motor traces, and clock edges. For CTMU-based capacitive sensing, keep electrode traces short and isolate them from ground pours where the application permits. Use a quiet reference and grounded shield strategy where needed, and validate ADC accuracy with the actual sensor, cable, enclosure, and power-conversion hardware rather than relying only on nominal converter resolution.
