PIC24FV32KA304T-I/MV Übersicht
What is a 16-bit microcontroller? A 16-bit MCU (microcontroller unit) is a small computer-on-a-chip with a 16-bit data path, on-chip Flash program memory, SRAM data memory, and integrated peripherals (ADC, timers, communication buses, GPIO). Within the broader semiconductor taxonomy, the PIC24FV32KA304 sits under: microcontroller -> embedded MCU -> 16-bit MCU -> Microchip PIC24F/PIC24FV family -> PIC24FV32KA304 sub-family. It is intended to bridge 8-bit PIC® MCU users who are outgrowing their current platform without jumping to 32-bit parts.
Key features of this part include 32KB Flash, 2KB SRAM, 512 bytes of EEPROM, 17 usable I/O pins, an integrated 12-bit ADC with up to 16 input channels, the CTMU (Charge Time Measurement Unit) for capacitive touch and time-of-flight measurements, multiple UART/SPI/I²C peripherals, and a Real-Time Clock and Calendar (RTCC) that keeps running in Deep Sleep. The “T” suffix indicates tape-and-reel packaging, the “I” is the industrial -40°C to +85°C temperature range, and “MV” denotes the 48-UQFN 6x6 mm package.
Architecturally, the PIC24FV32KA304 uses Microchip's modified Harvard architecture with a 16-bit data path and 24-bit instruction word, providing 32 MHz performance at modest power. XLP technology — DSBOR, DSWDT, deep-sleep RTCC — combined with nanoWatt XLP peripherals delivers deep-sleep currents in the nanoamp range, making the part well-suited for always-on sensor nodes. Brown-out reset, watchdog timer, and code protection support robust field deployment.
Typical applications include battery-powered sensor nodes, IoT end nodes, capacitive touch user interfaces, low-power medical devices, portable consumer products, and industrial sensor conditioning. Engineers select this part when they need 16-bit performance, generous Flash, and the option of 5V tolerance in a compact UQFN-48 footprint.
Designers should plan for an external decoupling network on every AVDD/VDD pin pair, route ICPGCx/ICPGDx pairs as matched-length pairs for stable in-circuit programming, and budget for the 48-pin UQFN PCB escape — at 6x6 mm the part is small enough for hand prototypes but may need a reflow profile with controlled ramp rates. Compared to 8-bit PIC16/PIC18 devices, the PIC24F family offers significantly more compute and peripherals at comparable cost and far better power efficiency in sleep modes.
This page consolidates distributor pricing, package-compatible Microchip family alternatives, and practical PCB/firmware design notes drawn from the PIC24FV32KA304 family datasheet, giving engineers a single reference for evaluation, sourcing, and schematic review.

Typische Anwendungen
PIC24FV32KA304T-I/MV ist geeignet für 7 Anwendungs: Battery-Powered IoT Sensor Nodes, Capacitive Touch User Interface, Portable Medical Monitoring, Industrial Sensor Conditioning, Automotive Aftermarket Accessories, Low-Power Data Logging, Smart Home Edge Devices.
Battery-Powered IoT Sensor Nodes
The PIC24FV32KA304T-I/MV is well matched to wireless sensor nodes running from CR2032 or 2xAA cells. Its nanoWatt XLP deep-sleep current (~nA range with RTCC active) lets the MCU stay asleep for >99% of the duty cycle while still maintaining a real-time clock wake schedule. The 1.8–5.5 V supply range means the same board can run from a 3.0 V lithium primary or a 3.6 V LiSOCl2 cell without level shifting. Pair with a sub-GHz radio like the MRF89XA for metering, environmental monitoring, or asset-tracking nodes where multi-year battery life is the design constraint.
Empfohlen
Capacitive Touch User Interface
For appliance front panels, smart locks, and consumer products, the integrated CTMU (Charge Time Measurement Unit) plus 12-bit ADC enables 4–8 capacitive touch buttons or a small slider without an external touch controller IC. The CTMU provides the precise current source required for time-based capacitance measurement, and the 16 MIPS CPU executes mTouch™ decoding and debouncing in real time. The 32 KB Flash holds both the touch library and the application logic, and the 1.8–5.5 V supply range supports both battery and USB-powered appliances without a separate LDO.
Empfohlen
Portable Medical Monitoring
The PIC24FV32KA304T-I/MV suits portable medical devices such as pulse oximeters, glucose meters, and wearable fitness patches where low average power, deterministic 16-bit processing, and reliable in-circuit programming matter. The CTMU can be configured for time-of-flight optical measurement used in heart-rate and SpO2 front-ends. Deep-sleep currents under 1 µA (with RTCC active) extend battery life on small Li-ion cells, and the 32 KB Flash accommodates application code plus FDA-traceable calibration constants stored in 512 B EEPROM. Industrial -40 °C to +85 °C range covers most consumer medical environments.
Empfohlen
Industrial Sensor Conditioning
In factory automation and process control, the PIC24FV32KA304T-I/MV provides 16-bit compute and a 12-bit ADC with 16 channels for conditioning 4–20 mA loop sensors, thermistors, and bridge-type pressure transducers. The 1.8–5.5 V supply tolerance lets it run directly from 24 V industrial bus through a small LDO, while the wide operating temperature handles cabinet environments. The 32 KB Flash is ample for Modbus RTU or IO-Link device stacks, and the UART/SPI/I2C peripherals allow simultaneous connection to an HMI display, a sensor, and an RS-485 transceiver.
Empfohlen
Automotive Aftermarket Accessories
For non-safety automotive accessories such as cabin environmental monitors, OBD-II readers, and aftermarket lighting controllers, the PIC24FV32KA304T-I/MV provides 5 V tolerance required for direct connection to vehicle 12 V-derived rails after a TVS clamp. The integrated CAN-friendly peripherals (UART/SPI for external CAN transceivers like MCP2515) and the wide temperature range cover most in-cabin use cases. For under-hood or safety-critical applications, choose the AEC-Q100-qualified PIC24F family member instead; this "I" industrial-grade part is appropriate for cabin-tier accessories only.
Empfohlen
Low-Power Data Logging
The PIC24FV32KA304T-I/MV's 32 KB Flash plus 512 B EEPROM provides adequate storage for time-stamped logging of temperature, humidity, or vibration data over weeks-long intervals in environmental monitoring applications. The RTCC running in deep sleep allows scheduled wake and store cycles without CPU intervention, and the 12-bit ADC samples multiple sensors at wake. USB connectivity is not integrated, so logging data is retrieved either via UART to a host or by swapping an external EEPROM. Total system quiescent current under 5 µA supports multi-year deployments on AA cells.
Empfohlen
Smart Home Edge Devices
For smart home edge controllers such as thermostat remote sensors, occupancy detectors, and BLE-mesh nodes, the PIC24FV32KA304T-I/MV provides the XLP low-power envelope needed for coin-cell or wall-battery operation while leaving enough Flash for Zigbee or BLE application stacks (with the radio hosted by an external module). The 17 I/O pins drive a handful of LEDs, buttons, and a sensor interface, while the CTMU handles capacitive front-panel touch. The wide supply range simplifies direct connection to 2xAA alkaline cells or a 5 V USB-powered wall adapter.

Designhinweise
The 48-pin UQFN (MV) package at 6x6 mm has a central exposed thermal pad that must be soldered to a copper pour connected to VSS for both thermal dissipation and electrical grounding. Place a 4–6 via array (0.2–0.3 mm drill) under the pad to the internal ground plane. Decouple every VDD/AVDD pin pair with a 0.1 µF X7R ceramic placed within 2 mm of the pin; add a single 4.7 µF bulk capacitor near the package.
Route the ICSP pair PGED1/PGEC1 (or PGED2/PGEC2) as a tightly-matched-length differential pair from the PICkit/ICD connector to the MCU pins. Keep trace length under 50 mm and avoid crossing them with switching signals. Per the family datasheet, both ICSP pairs are functional but only one pair needs to be populated on the production board for programming — typically the PGED1/PGEC1 pair closest to the connector edge.
The PIC24FV32KA304T-I/MV's internal voltage regulator requires a low-ESR 1 µF–10 µF ceramic capacitor on the VCAP pin (pin 8) to stabilize the core 1.8 V rail. Use X5R or X7R dielectric rated for at least 6.3 V. The MCU's wide 1.8 V–5.5 V input range means the same VCAP design works across all supported supply voltages, simplifying the BOM for multi-rail products.
When migrating between PIC24FV (wide 1.8–5.5 V) and PIC24F (1.8–3.6 V) variants in the same family, do not assume the I/O pin voltage tolerance is identical. The "V" parts (e.g., PIC24FV32KA304) include 5 V-tolerant digital inputs and a 5 V-tolerant ADC reference path; the "F" parts (e.g., PIC24F32KA304) limit absolute maximum pin voltage to VDD + 0.3 V. Apply the appropriate derating when designing universal PCBs.
For capacitive touch designs using the CTMU, add a 1 nF–10 nF series damping resistor close to the CTMU output pin to slow the edge and reduce EMI susceptibility. The CTMU's charge time measurement is sensitive to ground bounce; keep the touch sensor traces short (<25 mm) and shield them with a ground guard ring connected to analog ground (AVSS) to prevent false triggers from adjacent signals.
