PIC24FV16KM104T-I/PT Overview
What is a PIC24F microcontroller? The PIC24F is Microchip's 16-bit MCU family, positioned between the 8-bit PIC16/PIC18 and the 32-bit PIC32 families. PIC24F devices use a 16-bit data path, a 24-bit instruction word, a hardware multiplier, and a 16-element working register array, delivering 1.5 DMIPS/MHz instruction throughput. Within this family, the KM104 sub-family adds nanoWatt XLP extreme-low-power technology (deep sleep < 100nA typical), Configurable Logic Cells (CLC), and a 12-bit ADC with up to 500 ksps sampling.
Key features include hardware multiply/divide, a 32MHz internal oscillator with PLL, multiple Capture/Compare/PWM (MCCP/SCCP) peripherals, 12-bit ADC, comparators, and a Peripheral Pin Select (PPS) mapping engine that reassigns digital I/O functions to any pin. The wide 2.0V-5.5V operating range means a single part can be powered from a Li-ion cell or a regulated 5V supply without redesign, while the XLP modes enable multi-year battery life in always-on sensors.
Typical applications include low-power IoT sensor nodes, USB device controllers (with companion PIC32 USB interface), battery-powered medical monitors, industrial control panels, and consumer devices that need a compact 16-bit core with rich peripherals but cannot justify a 32-bit part.
When designing with this part, verify the suffix decoding - "-I/PT" indicates industrial temperature grade (-40C to +85C) and TQFP-44 packaging. Use MPLAB X IDE with the XC16 compiler for development. Place a 0.1uF decoupling capacitor adjacent to every VDD/VSS pair and route analog and digital grounds as a star at the device.

Typical Applications
PIC24FV16KM104T-I/PT is suitable for 7 applications: Battery-Powered IoT Sensor Nodes, Low-Power Industrial Control Panels, Portable Medical Monitoring Devices, USB Device / HID Peripherals, Automotive Body Electronics (Non-Safety), Consumer Appliance User Interfaces, Smart Home Sensor Hubs.
Battery-Powered IoT Sensor Nodes
The PIC24FV16KM104T-I/PT's nanoWatt XLP technology achieves deep-sleep currents below 100nA while retaining RAM, making it ideal for battery-powered IoT sensor nodes that must run for years on a CR2032 or 2xAA cells. The 16-bit 32MHz PIC24F core delivers 16 MIPS sufficient for periodic sensor reads, local filtering, and low-rate wireless protocol stacks (LoRa, Sub-GHz proprietary, BLE via companion radio).
Recommended
Low-Power Industrial Control Panels
With 12-bit ADC, MCCP/SCCP PWM modules, and 16 MIPS throughput, the PIC24FV16KM104T-I/PT fits compact industrial control panels that read analog sensors, drive PWM-controlled actuators, and communicate over UART/SPI/I2C to higher-level controllers. The wide 2.0V-5.5V supply lets the same PCB accept 5V industrial rails or 3.3V logic-level backplanes without redesign.
Recommended
Portable Medical Monitoring Devices
The PIC24FV16KM104T-I/PT is well suited to portable medical devices such as pulse oximeters, glucose meters, and ambulatory ECG patches that demand low EMI, long battery life, and reliable ADC conversion. The 12-bit ADC captures bioelectric signals, while XLP sleep modes extend operating life on small coin cells. The industrial temp grade (-40C to +85C) covers most clinical environments.
Recommended
USB Device / HID Peripherals
Although the PIC24FV16KM104T-I/PT itself lacks integrated USB, it can implement USB device or HID peripheral functions using the PPS (Peripheral Pin Select) engine to remap UART/SPI to the D+/D- lines via an external USB transceiver or via bit-banging firmware. Its 16 MIPS is sufficient for HID-class devices (keyboards, mice, custom controllers) where deterministic latency is needed.
Recommended
Automotive Body Electronics (Non-Safety)
In non-safety automotive body electronics (interior lighting, seat controllers, accessory multiplexers), the PIC24FV16KM104T-I/PT delivers 16 MIPS, 12-bit ADC, and CLC logic that can replace discrete glue logic. Its wide 5.5V VDD tolerance tolerates automotive load-dump transients when paired with proper TVS protection, and the -40C to +85C industrial temp range covers most cabin environments.
Recommended
Consumer Appliance User Interfaces
Consumer appliances (coffee machines, vacuum robots, smart kitchen devices) use the PIC24FV16KM104T-I/PT to drive segmented LCDs, capacitive touch via CLC peripherals, PWM fans or pumps, and UART/Wi-Fi links. The wide voltage range accepts single-cell Li-ion or wall-adapter 5V, and XLP sleep modes let battery-backed appliances retain RTC and last setting across long idle intervals.
Recommended
Smart Home Sensor Hubs
The PIC24FV16KM104T-I/PT can act as a low-cost sensor hub aggregating multiple I2C/SPI sensors (temperature, humidity, light, motion) before forwarding data over UART, BLE, or Sub-GHz to a gateway. CLC peripherals implement hardware debouncing and edge detection without CPU load, freeing the 32MHz core for sensor fusion and protocol framing.

Design Notes
Decoupling: Place a 0.1uF ceramic capacitor within 5mm of every VDD/VSS pair (pins 5/6 and 29/30 on TQFP-44). Add a bulk 10uF tantalum or ceramic on the main VDD rail. The AVDD/AVSS pins (15/16) require an additional 0.1uF + 10uF pair to filter analog supply noise. Power-on sequencing is automatic; the PIC24F handles power-on reset internally.
Thermal limits for TQFP-44 at 32MHz: typical theta_JA is around 50-60 C/W depending on PCB copper area. At full CPU load and 5.5V supply, the part dissipates roughly 50-80mW, yielding a self-heating rise under 5C - not a concern. In sealed enclosures with no airflow, derate by 10% above 70C ambient to be safe.
Crystal/oscillator layout: Place the crystal or ceramic resonator within 5mm of OSC1/OSC2 (pins 7/8). Use a guard ring tied to ground around the oscillator traces. If using the internal 32MHz PLL with 8MHz crystal, keep the crystal traces short and symmetric. Avoid running noisy digital signals under the oscillator area.
MCLR pin (pin 13) must NOT be left floating. Tie it to VDD through a 10k resistor, or directly to VDD if no external reset is needed. An open MCLR causes intermittent resets and debug failures. Also, ensure unused I/O are configured as outputs (driven low) or inputs with internal weak pull-ups to minimize current draw in XLP sleep modes.
PPS remapping caveat: When using Peripheral Pin Select to remap peripherals, configure ALL pin mappings before enabling the peripheral - changing PPS mid-operation can cause glitches. For EMI-sensitive designs, place the MCU away from high-frequency switching nodes and use a 4-layer PCB with dedicated ground plane.
