PIC24F16KM104T-I/MV Overview
What is a 16-bit microcontroller? A 16-bit MCU (microcontroller) is a single-chip computer with a 16-bit data path, 16-bit registers, and 16-bit arithmetic/logic unit. Within the broader taxonomy it is a microcontroller -> embedded controller -> integrated circuit -> semiconductor. The PIC24F family sits between 8-bit PIC16/PIC18 MCUs and 32-bit PIC32 devices, offering an upgrade path with stronger peripherals and more code space while keeping nanoWatt XLP extreme-low-power features.
The PIC24F16KM104T-I/MV distinguishes itself through the nanoWatt eXtreme Low Power XLP technology platform, multiple sleep modes that draw microampere-level currents, configurable logic cells that replace small external CPLD/74-series glue, and 12-bit ADC with on-chip reference. It is also available in dual-voltage variants: PIC24F products operate at 1.8V-3.6V while PIC24FV versions support 2.0V-5.5V for 5V tolerant designs.
Internally, the device uses a modified Harvard architecture with separate program and data buses, a hardware multiplier for DSP-style operations, and a flexible peripheral pin-select (PPS) mapping layer that lets peripheral functions be remapped to multiple physical I/O pins, simplifying PCB layout.
Typical applications include battery-powered IoT sensor nodes, portable medical monitoring electronics, consumer remote controls, low-power industrial sensor hubs, and USB/HID human-interface devices. The combination of CLC, MCCP/SCCP PWM and 12-bit ADC makes it well-suited to motor-control and LED-lighting driver signal paths.
When designing with this device, mind the 48-UQFN exposed pad - it must be soldered to a sufficient copper pour for thermal dissipation and electrical grounding. Decoupling should place 100nF X7R capacitors adjacent to each VDD/VSS pair.

The 48-UQFN 6x6 mm footprint suits miniature sensor PCBs, and the CLC peripheral can replace external glue logic for sensor wake-up sequencing. Operates 1.8 V-3.6 V directly from a single CR2032 or 2xAA cell stack.
Recommended
Portable Medical Monitoring Devices
The PIC24F16KM104T-I/MV supports portable medical monitoring through 12-bit ADC accuracy for vital-sign analog front-ends and nanoWatt XLP sleep modes for week-long battery life. The 16 KB Flash accommodates Bluetooth Low Energy profiles and a small RTOS, and the 1 KB SRAM buffers sensor data between radio transmissions.

Key Differentiators
- Configurable Logic Cell (CLC) peripheral (vs PIC24F16KA304-I/MV)
- Twice the program Flash of KM204 (vs PIC24F08KM204T-I/MV)
- Higher-grade ADC vs low-cost KL family (vs PIC24F16KL402-I/ML)
Design Notes
The 48-UQFN package has an exposed thermal pad that MUST be soldered to a ground copper pour to meet thermal and electrical specifications. At maximum 32 MHz operation across the -40C to +85C industrial range, dissipation is typically <100 mW for this device class, but a minimum 1 square inch of 1 oz copper pour is recommended for the exposed pad. Without the pad properly soldered, the junction temperature may exceed datasheet limits under heavy peripheral load.
Decoupling: place one 100 nF X7R ceramic capacitor adjacent to each VDD/VSS pair on the PIC24F16KM104T-I/MV. For low-noise analog designs, add a 10 uF bulk capacitor near the package. Route analog and digital grounds separately and join at a single point near the MCU's VSS pin. PPS (Peripheral Pin Select) signals should be routed away from oscillator traces to minimize jitter.
Do not confuse PIC24F (1.8V-3.6V) with PIC24FV (2.0V-5.5V) variants - applying 5 V to a PIC24F part will damage it. Verify your firmware size fits within 16 KB Flash (5.5K x 24 words) plus configuration space. The CONFIG register settings must match your oscillator choice and watchdog configuration, otherwise the MCU may lock up. Always program the WDT and BOR (brown-out reset) settings in your production firmware.
Route the 32 MHz oscillator traces symmetrically and as short as possible, surrounded by a ground guard ring. Keep the OSC1/OSC2 traces within 5 mm of the MCU pins to minimize parasitic capacitance. For USB applications, the 48-UQFN has no dedicated USB pins - use a USB-capable PIC24F variant or pair with an external MCP2221A bridge. Place CLC signal traces near the package to avoid additional propagation delay through long PCB traces.
