PIC24FV16KM204-I/MV Overview
An MCU (Microcontroller Unit) is a single-chip computer containing a CPU core, program memory (Flash), data memory (RAM), and integrated peripherals. The PIC24FV family is built on a 16-bit modified-RISC architecture with DSP enhancements, positioned within Microchip's hierarchy as PIC24F (16-bit, low-power) -> 16-bit MCU -> microcontroller -> embedded processor -> semiconductor. Its XLP technology targets sleep currents below 1 µA, enabling years of operation from a single coin cell.
Key features include up to 37 digital I/O pins, four 16-bit timers, two UART, two SPI, two I²C, three 16-bit Capture/Compare/PWM modules, a Charge Time Measurement Unit (CTMU), and a Peripheral Trigger Generator that offloads complex sequencing from the core. The integrated op amps and 12-bit ADC deliver up to 200 ksps conversion, supporting sensor-conditioning front-ends without external analog ICs.
The PIC24FV16KM204 family uses a Harvard architecture with separate program and data buses, 24-bit instruction word with DSP-aware addressing, and hardware multiply/divide. Peripherals connect via the Peripheral Pin Select (PPS) mapper, allowing flexible pin assignment for serial interfaces, which simplifies PCB routing in space-constrained designs.
Typical applications include portable medical devices, sensor node firmware, IoT edge nodes, USB/HID peripherals, low-cost motor drive control, and general-purpose industrial controllers requiring mixed analog/digital integration. Designers favor this family when combining small PCB footprints with on-chip op amps and DACs.
When designing with this MCU, ensure decoupling capacitors of 0.1 µF and 1 µF are placed within 5 mm of each VDD pin, leave the thermal pad soldered for thermal and electrical ground integrity, and follow the PPS configuration sequence in code to avoid unintended peripheral lock-ups.

Typical Applications
PIC24FV16KM204-I/MV is suitable for 7 applications: Portable Medical Devices, Battery-Powered IoT Sensor Nodes, USB/HID Peripherals, Low-Cost Motor Drive Control, Industrial Sensor Conditioning, Capacitive Touch Interfaces, General-Purpose Embedded Control.
Portable Medical Devices
The PIC24FV16KM204-I/MV fits portable medical devices because its XLP sleep current under 1 µA enables multi-year coin-cell operation on devices such as pulse oximeters, glucose meters, and digital thermometers. The 12-bit ADC sampling at up to 200 ksps provides sufficient resolution for biosignal front-ends, and the on-chip op amps amplify sensor signals without extra analog ICs, reducing BOM cost and PCB area. The 2.0-5.5 V supply range supports both 3 V coin cells and 5 V USB-powered designs in clinical environments.
Recommended
Battery-Powered IoT Sensor Nodes
The PIC24FV16KM204-I/MV is purpose-built for battery-powered IoT sensor nodes thanks to XLP technology that delivers nanoamp sleep currents while preserving RTC and RAM retention. The integrated 12-bit ADC samples environmental sensors (temperature, humidity, light) directly, and the two UART/SPI/I²C peripherals connect radios such as LoRa, Sub-GHz, or BLE modules. The 16 KB Flash accommodates lightweight IPv6/6LoWPAN stacks or vendor-specific IoT firmware, and the 48-pin UQFN (MV, 6x6 mm) package fits sub-1 square-inch node PCBs.
Recommended
USB/HID Peripherals
The PIC24FV16KM204-I/MV serves USB/HID peripherals such as custom keyboards, mice, and game controllers where its 32 MIPS performance drives HID polling and on-device processing. The Peripheral Pin Select (PPS) mapper assigns USB D+/D- to any digital I/O, easing PCB routing, while the 16 KB Flash fits HID descriptors plus vendor-specific report logic. The 2.0-5.5 V range supports both bus-powered (5 V) and self-powered (3.3 V regulated) USB designs without external level shifters.
Recommended
Low-Cost Motor Drive Control
The PIC24FV16KM204-I/MV drives low-cost brushed DC and stepper motors via its three 16-bit CCP/PWM modules with complementary outputs and programmable dead-band, supporting 6-step or sinusoidal commutation in firmware. The integrated op amps sense motor current through shunt resistors, while the 12-bit ADC samples back-EMF for sensorless control, eliminating external current-sense amplifiers. The wide 2.0-5.5 V range suits 3.3 V or 5 V motor-logic rails alongside separate motor supplies.
Recommended
Industrial Sensor Conditioning
The PIC24FV16KM204-I/MV is ideal for industrial sensor conditioning front-ends where the integrated 12-bit ADC, op amps, DAC, and comparators implement transducer excitation, amplification, filtering, and thresholding on a single chip. The Peripheral Trigger Generator (PTG) sequences ADC conversions autonomously, freeing the core for communication tasks via UART/SPI/I²C to upstream PLCs or HMIs. The 48-pin UQFN (MV, 6x6 mm) package fits dense DIN-rail mounted signal-conditioning modules with industrial -40C to +85C temperature range.
Recommended
Capacitive Touch Interfaces
The PIC24FV16KM204-I/MV implements capacitive touch buttons and sliders using the on-chip Charge Time Measurement Unit (CTMU), which measures capacitance changes with sub-nanosecond resolution for reliable touch detection under humidity and glove conditions. The Configurable Logic Cells (CLC) generate custom timing waveforms without CPU intervention, and the 12-bit ADC provides redundant analog touch measurements. The 2.0-5.5 V range supports battery and USB-powered touch panels in appliances and consumer electronics.
Recommended
General-Purpose Embedded Control
The PIC24FV16KM204-I/MV handles general-purpose embedded control tasks in appliance, building automation, and consumer electronics where its balanced peripheral mix replaces multiple discrete ICs. Two UART, two SPI, and two I²C interfaces support multi-bus topologies, while the 4 x 16-bit timers drive time-critical event sequencing. The Harvard bus architecture and 32 MIPS throughput deliver responsive control loops with predictable interrupt latency for real-time embedded firmware.

Key Differentiators
- On-chip op amps + 12-bit ADC + 8-bit DAC in 48-pin UQFN (vs DSPIC33EV64GM104-I/PT)
- XLP technology with sub-1 µA sleep current (vs PIC18F46K22-I/PT)
- Wide 2.0-5.5 V supply in same footprint as 3.3 V variant (vs PIC24F16KM204-I/MV)
Design Notes
Place 0.1 µF and 1 µF decoupling capacitors within 5 mm of every VDD/VSS pin pair. According to Microchip's PIC24FV16KM204 family datasheet, the analog and digital supply pins (AVdd/AVss) require separate filtering from VDD/VSS to prevent ADC noise coupling; route AVdd from VDD via a ferrite bead and decouple with 10 µF + 0.1 µF. Estimated: input current at 32 MHz active mode is ~10 mA typical, so decoupling must handle sub-microsecond transient demands without voltage droop.
Solder the UQFN-48 thermal pad to a continuous ground plane with at least 8 thermal vias to inner ground layers. Estimated: at 32 MHz active and 5 V supply, power dissipation is approximately 50 mW worst case (10 mA × 5 V), yielding negligible junction-temperature rise, but the thermal pad is also the electrical ground return and must be soldered for signal integrity and EMC compliance.
Configure the Peripheral Pin Select (PPS) mapper in firmware before enabling peripherals; the PIC24FV16KM204 family datasheet warns that peripherals default to disabled states and incorrect PPS unlock sequences can lock the device, requiring a power cycle to recover. Route the 32 MHz crystal traces on the top layer with short, symmetric lengths to OSC1/OSC2 and guard them with a ground pour to minimize EMI.
Do not exceed 5.5 V on any VDD pin; the PIC24FV (wide-voltage) variant supports up to 5.5 V, but the F variant without V tops out at 3.6 V. Use the ICSP programming pins (RB0/RB1) only after disabling PPS on those pins in firmware, otherwise in-circuit programming will fail. The CTMU requires calibration against a known reference capacitor before touch measurements will be reliable.
Compliance Information
Industrial temperature grade -40C to +85C (I suffix). Not AEC-Q100 qualified; choose PIC24F automotive-grade variants for vehicle applications.
