PIC24FV16KM204T-I/ML Overview
A 16-bit microcontroller (MCU) is a programmable processor with a 16-bit data path and instruction word, positioned between 8-bit and 32-bit MCUs in the embedded hierarchy: 8-bit MCU -> 16-bit MCU -> 32-bit MCU -> microprocessor. PIC24F devices extend the legacy PIC instruction set with 16-bit instructions and enhanced DSP-like addressing, while preserving the deterministic PIC interrupt model. The XLP (eXtreme Low Power) technology pushes sleep current into the nanoampere range, enabling battery-powered designs that run for years on a single coin cell.
Key differentiating features include the integrated 12-bit ADC with up to 22 channels, two 8-bit DACs, multiple op amps and comparators on-chip, and a CLC that lets designers wire combinational logic in hardware without external gates. Connectivity is provided by I2C, SPI, UART/USART, IrDA, and LINbus peripherals. The 'T' suffix indicates Tape and Reel packaging, while the -I/ML suffix specifies the Industrial temperature range (-40C to +85C) and 44-QFN (8x8) package.
Typical applications include portable medical devices, IoT sensor nodes, battery-powered instrumentation, automotive body controllers (LIN slaves), and consumer white goods with capacitive touch. The wide operating voltage (2V to 5.5V) allows direct connection to single-cell Li-ion or 2xAA alkaline supplies without external regulators, and the integrated analog chain reduces BOM cost and PCB area compared to MCUs requiring external ADCs.
Designers should note that the 44-QFN package has an exposed thermal pad that must be soldered to the PCB ground plane for proper thermal and electrical performance. Programming is supported via Microchip's MPLAB X IDE with the XC16 compiler and the PICkit or ICD debugger families.

Typical Applications
PIC24FV16KM204T-I/ML is suitable for 7 applications: Battery-Powered IoT Sensor Node, Portable Medical Monitoring Device, Automotive LIN Bus Slave Node, Industrial Process Transmitter, Consumer White Goods with Touch UI, Smart Home Sensor Hub, Test and Measurement Handheld Instrument.
Battery-Powered IoT Sensor Node
The PIC24FV16KM204T-I/ML fits battery-powered IoT sensor nodes because its 2.0V-5.5V wide-voltage range allows direct connection to single-cell Li-ion or 2xAA batteries without boost converters, while XLP technology pushes sleep current into the nanoampere range. Its 22-channel 12-bit ADC digitizes multiple sensors, and the 16KB Flash comfortably hosts a BLE/Zigbee stack or LoRaWAN driver. The integrated 8-bit DACs and op amps enable local sensor excitation and signal conditioning, eliminating external analog ICs.
Recommended
Portable Medical Monitoring Device
For portable medical monitors such as pulse oximeters and blood-pressure cuffs, the PIC24FV16KM204T-I/ML provides the integrated op amps needed for bio-sensor signal conditioning, plus 12-bit ADC resolution adequate for SpO2 and ECG front-ends. Its 2.0V minimum supply matches a single Li-ion cell, and the CLC enables hardware-level heart-rate detection without CPU wake-up, extending battery life. The 32MHz MIPS performance is more than sufficient for filtering and display-update tasks.
Recommended
Automotive LIN Bus Slave Node
In automotive body-control LIN slaves (window regulators, mirror controllers, seat switches), the PIC24FV16KM204T-I/ML serves as a low-cost slave controller. The integrated LINbus peripheral handles LIN 1.x/2.x framing in hardware, and the 12-bit ADC reads position sensors directly. With -40C to +85C industrial temperature range and 2V-5.5V supply tolerance, it survives 12V automotive transients when paired with an external voltage regulator. The 44-QFN package is footprint-compatible with the PIC24FJ64GB004T-I/ML higher-memory cousin.
Recommended
Industrial Process Transmitter
4-20mA loop-powered industrial transmitters benefit from the PIC24FV16KM204T-I/ML's 2.0V minimum supply - it can run directly from a 4mA loop bias. The 22 ADC channels support multi-sensor input (pressure, temperature, flow), and the 8-bit DACs provide loop-current control feedback. The CLC implements hardware linearization for thermocouple tables, offloading CPU cycles. Industrial temperature rating and wide-voltage tolerance meet IEC 61000 EMC immunity needs when paired with proper TVS protection.
Recommended
Consumer White Goods with Touch UI
Washing machines, dishwashers, and induction cooktops use the PIC24FV16KM204T-I/ML as the main HMI controller, leveraging the 22 ADC channels to read capacitive-touch electrodes via the integrated CTMU peripheral and op amps. The 32MHz CPU drives segmented LCD or LED displays, while PWM outputs control motor/relay drivers. Wide operating voltage accommodates rectified 24V mains rails after step-down, and the 44-QFN package fits compact appliance PCBs.
Recommended
Smart Home Sensor Hub
The PIC24FV16KM204T-I/ML anchors a smart-home sensor hub by aggregating temperature, humidity, motion (PIR), and light sensors via its 22-channel ADC. UART/USART communicates with a Wi-Fi or BLE companion module, while I2C drives an OLED display. XLP nanoamp sleep enables battery-powered window/door sensors with multi-year coin-cell life. Wide-voltage operation handles rechargeable CR2032 and 2xAAA configurations with a single BOM line.
Recommended
Test and Measurement Handheld Instrument
Handheld multimeters and clamp meters use the PIC24FV16KM204T-I/ML to digitize voltage/current via 12-bit ADC, drive LCD segments, and time interval measurements. The integrated op amps scale shunt-resistor voltages into ADC range, while CLC implements hardware frequency counters for non-CPU-bound measurements. 2KB RAM buffers sample streams before UART upload, and wide-voltage tolerance handles varying battery conditions. The 44-QFN 8x8 mm package fits the tight handheld enclosure.

Key Differentiators
- Wide-voltage 2.0V-5.5V operation in same QFN-44 footprint (vs PIC24F16KM204-I/ML)
- Higher memory density than '202 sibling (vs PIC24FV16KM202-I/ML)
- Tape and Reel packaging for high-volume SMT (vs PIC24FV16KM204-I/ML (tray))
- Industrial temperature range vs Extended temperature (vs PIC24FV16KM204-E/ML)
Design Notes
The 44-QFN (8x8 mm) package has an exposed thermal pad (pin 45 e-pad) that MUST be soldered to a PCB ground plane for proper thermal dissipation and electrical grounding. Microchip recommends at least 4 thermal vias (0.3mm drill, 1.0mm pitch) under the pad connecting to inner ground layers. Without proper soldering, junction temperature may exceed spec under sustained 32MHz operation.
Decouple VDD with both a 100nF ceramic capacitor placed within 3mm of pin 43 and a bulk 10uF tantalum or ceramic capacitor. For wide-voltage 2.0V-5.5V operation, ensure AVDD (if used) tracks VDD within 0.3V to avoid ADC reference errors. Add a ferrite bead if ADC measurements must reject switching-noise from a co-located DC-DC converter.
Do not program the internal PLL to 32MHz while VDD is below 2.4V - the PLL requires minimum 2.4V supply to meet jitter specs. Below 2.4V, run the part at the internal 8MHz RC without PLL. Also, the CLC peripheral must be explicitly enabled in the CLCxCON register; many designers forget this and assume CLC outputs are active by default after reset.
Keep the ICSP programming pins (PGED1=RB0, PGEC1=RB1) accessible on the PCB - either route to an in-circuit programming header or expose test pads. Microchip's PICkit 3/4 and ICD 4 debuggers require direct access to these pins; if they are dedicated to outputs, firmware debugging becomes impossible without rework. Reserve at least 50mm^2 of ground pour around the QFN package for thermal relief.
Compliance Information
RoHS and REACH compliant per Microchip product page. Industrial temperature grade (-40C to +85C) is not AEC-Q100 qualified; choose PIC24FV16KM204-E/ML for extended temperature or AEC-Q100 qualified variants for automotive.
