PIC24F16KM104T-I/PT Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory, working RAM, and a rich set of peripherals such as timers, communication interfaces, and analog channels. The PIC24F belongs to Microchip's 16-bit modified-Harvard architecture family, positioned above 8-bit PIC MCUs in computational performance and peripheral integration. It sits within the broader taxonomy: microcontroller -> embedded processor -> semiconductor IC.
Key features of this part include nanoWatt XLP sleep currents as low as 20 nA in deep sleep, multiple communication peripherals (I2C, SPI, UART, IrDA, and LIN), configurable logic cells (CLC), and a 12-bit ADC with multiple input channels. The integrated 32 MHz internal oscillator eliminates the need for an external crystal in many designs, reducing BOM cost and PCB area.
The PIC24F architecture uses a 16-bit modified-Harvard core with a 24-bit instruction word, enabling 32 MHz operation (16 MIPS) while retaining the deterministic interrupt response that PIC MCUs are known for. Peripheral features include up to 5 CCP/ECCP modules, multiple 16-bit timers, a hardware Real-Time Clock/Calendar (RTCC), and charge time measurement unit (CTMU) for capacitive touch sensing.
Typical applications include low-power IoT sensor nodes, battery-powered medical devices such as glucose meters and portable monitors, automotive LIN nodes for body and comfort electronics, industrial sensor transmitters, and consumer products requiring ultra-long battery life. The wide operating voltage range supports both 3V lithium and 1.8V-3.6V regulated supplies.
When designing with this device, the integrated 32 MHz oscillator and internal LDO simplify power-tree design; place decoupling capacitors (100 nF plus 10 µF bulk) within a few millimeters of the VDD pins to minimize digital switching noise on the analog rails.

Typical Applications
PIC24F16KM104T-I/PT is suitable for 7 applications: Battery-Powered IoT Sensor Nodes, Portable Medical Monitoring Devices, Automotive LIN Bus Nodes, Industrial Sensor Transmitters, Consumer Electronics with Touch Interfaces, Smart Energy Meters, Wireless Sensor Networks with Sub-GHz Radios.
Battery-Powered IoT Sensor Nodes
The PIC24F16KM104T-I/PT's nanoWatt XLP deep-sleep currents in the nanoamp range and integrated 32 MHz oscillator make it ideal for IoT sensor nodes powered by coin-cell or AA batteries. The 16 KB Flash holds typical LoRaWAN, Zigbee, or BLE peripheral drivers, while the 12-bit ADC reads analog sensors with 1 mV resolution. The device wakes in microseconds from deep sleep, samples the sensor, transmits a packet, and returns to sub-microamp sleep - achieving multi-year battery life on a single CR2032 cell.
Recommended
Portable Medical Monitoring Devices
Medical wearables such as pulse oximeters, glucose meters, and continuous monitoring patches benefit from the PIC24F16KM104T-I/PT's ultra-low sleep current and deterministic 16-bit core for sensor fusion algorithms. The Configurable Logic Cell offloads real-time sensor timing from the CPU, reducing active time and extending battery life. The 12-bit ADC and CTMU peripheral support accurate biometric measurements, while the small TQFP-44 footprint enables miniaturized form factors required for body-worn devices.
Recommended
Automotive LIN Bus Nodes
The PIC24F16KM104T-I/PT integrates a hardware LIN-bus interface alongside UART, making it drop-in compatible with automotive LIN 2.x body-electronics networks such as window controls, mirror adjusters, and seat-position modules. Its 1.8 V to 3.6 V operation tolerates the 12V automotive bus after external regulation, and the 32 MHz core processes LIN command frames within the 10 ms master-scheduled window. The TQFP-44 package is automotive-qualified at the family level.
Recommended
Industrial Sensor Transmitters
Industrial 4-20 mA loop-powered transmitters use the PIC24F16KM104T-I/PT for sensor linearization, fault detection, and HART-modem-free digital communication. The wide -40C to +85C industrial temperature range, robust 12-bit ADC, and 1 KB SRAM support typical compensation algorithms for RTD, thermocouple, and strain-gauge inputs. The integrated CCP/PWM modules can drive the 4-20 mA current loop directly via an external transistor, simplifying the analog output stage.
Recommended
Consumer Electronics with Touch Interfaces
The PIC24F16KM104T-I/PT's CTMU peripheral enables capacitive touch sensing on up to 16 channels without external touch controllers, ideal for white-goods control panels, smart-home keypads, and remote-control units. The Configurable Logic Cell handles touch-scan timing autonomously, freeing the CPU for user-interface logic. The 16 KB Flash stores touch libraries and application code, while the 1 KB SRAM supports small UI buffers and protocol stacks.
Recommended
Smart Energy Meters
Residential single-phase smart energy meters use the PIC24F16KM104T-I/PT for power-calculation, anti-tamper detection, and metrology logging. The 32 MHz core computes RMS voltage and current with the 12-bit ADC sampling at 4 ksps, while EEPROM stores tamper logs and calibration constants over the device's 20-year service life. The TQFP-44 footprint fits standard smart-meter PCBs, and the XLP sleep mode handles power-outage backup scenarios gracefully.
Recommended
Wireless Sensor Networks with Sub-GHz Radios
The PIC24F16KM104T-I/PT pairs naturally with Sub-GHz transceivers for proprietary and IEEE 802.15.4g wireless sensor networks, where its low active current and rapid wake-from-sleep enable duty-cycled operation under 0.1%. The integrated SPI port runs Sub-GHz radios such as the Microchip MRF89XA at full speed, while the 16 KB Flash stores MAC-layer protocol stacks and application code. Sleep currents below 1 µA extend battery life to 10+ years in periodic-reporting applications.

- Smaller Flash footprint for cost-sensitive designs (vs PIC24FJ64GP205-I/PT)
Design Notes
Estimated power budget: at 32 MHz active core, the PIC24F16KM104T-I/PT draws approximately 8 mA from a 3.3 V supply (26 mW). In deep sleep with RTCC enabled, current drops below 1 µA - a 4-order-of-magnitude reduction. Use the PIC24F XLP library's sleep()/wake() APIs and configure unused peripherals to OFF state via PMDx registers to minimize sleep current. Place a 100 nF decoupling capacitor within 3 mm of every VDD pin, plus a single 10 µF bulk capacitor near the package.
Estimated junction temperature: at maximum active current 8 mA, 3.6 V supply, and 32 MHz operation, total power dissipation is approximately 29 mW. With TQFP-44 theta_JA of approximately 50 C/W on a 4-layer JEDEC test board, junction temperature rises only 1.5 C above ambient - well within the -40C to +85C industrial rating. No heatsinking is required for any normal operating mode.
Place the 32.768 kHz crystal (if used for RTCC) within 5 mm of the SOSCO/SOSCI pins and guard the traces with a ground ring to reduce noise injection into the oscillator. Keep ADC analog traces separated from digital switching traces by at least 3 mm or use a ground-fill moat. The TQFP-44 footprint requires 0.5 mm pitch traces with 0.2 mm via-in-pad recommended for thermal via arrays under the exposed pad if present in your variant.
Do not leave the MCLR pin floating - either tie it to VDD through a 10 kΩ pull-up or use an RC reset circuit with a 10 kΩ/100 nF time constant. Failing to do so results in spurious resets from EMI. Also note that the PIC24F16KM104 uses the 'F' (3.3 V) core - applying 5 V to VDD will permanently damage the silicon; use the PIC24FV variant if 5 V tolerance is needed.
When using the internal 8 MHz oscillator with PLL to reach 32 MHz, the PLL loop filter components (if external) must be placed within 5 mm of the PLL pins with no digital traces crossing underneath. For noise-sensitive analog measurements, average multiple ADC samples and use the dedicated VREF+ pin for external reference rather than VDD to reduce digital-noise coupling. Configure unused GPIO pins as outputs driven low to minimize switching current on floating inputs.
