PIC24FV16KM204-I/ML - 16-Bit XLP MCU, 16KB Flash, 44-QFN | Microchip
MPN: PIC24FV16KM204-I/ML ✓ Hoạt độngPIC24FV16KM204-I/ML Tóm tắt
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash), working memory (RAM), data EEPROM and a rich peripheral set. The PIC24F belongs to the 16-bit PIC family, which sits hierarchically between the 8-bit PIC16/PIC18 families and the 16-bit dsPIC33 DSP-capable family. XLP technology is Microchip's brand for nanoWatt-class sleep currents targeting battery applications. The 'V' prefix in PIC24FV denotes wide operating voltage (1.8 V to 5.5 V), making the part suitable for both 3.3 V and 5 V rails.
Key features include 16 KB Flash, 2 KB SRAM, three 16-bit timers, multiple UART/SPI/I2C interfaces, 12-bit ADC up to 500 ksps, dual rail-to-rail op amps, an 8-bit DAC, three analog comparators, configurable logic cells (CLC), and a peripheral pin select (PPS) subsystem. The device supports up to 32 MIPS performance at 32 MHz and includes a real-time clock calendar (RTCC) with calendar mode.
Architecturally, the PIC24FV16KM204 uses a modified Harvard 16-bit RISC core with single-cycle bit operations and hardware multiply, allowing deterministic interrupt response in C-language designs. The on-chip op amps and DAC enable closed-loop analog signal conditioning without external components, while the CLC peripheral implements glue-logic functions in hardware.
Typical applications include low-power IoT sensor nodes, battery-powered instrumentation, portable medical monitors, smart energy metering and consumer HMI with touch sensing. The wide-voltage range suits 2xAA battery packs and 5 V industrial sensors.
A key design consideration is selecting the right low-power mode. Sleep current at 1.8 V can drop below 20 nA with RTCC and external interrupts active, but enabling ADC or op amps raises consumption - profile each mode against your duty-cycled workload.

Ứng dụng tiêu biểu
PIC24FV16KM204-I/ML phù hợp cho 7 Áp dụngs: Battery-Powered IoT Sensor Node, Portable Medical Monitoring Device, Industrial Sensor Conditioning and 4-20 mA Loop, Smart Energy Meter and Submeter, Consumer HMI with Capacitive Touch, Automotive Body and Sensor Modules, Portable Test and Measurement Instrumentation.
Battery-Powered IoT Sensor Node
The PIC24FV16KM204-I/ML's XLP deep-sleep current under 20 nA at 1.8 V, integrated 12-bit ADC and on-chip dual op amps make it ideal for battery-powered IoT sensor nodes. In a typical design, a single 2xAA battery pack or CR2032 coin cell powers the MCU directly across the full 1.8 V to 5.5 V wide Vdd range, with the op amp conditioning a sensor bridge before the ADC samples at 500 ksps. The CLC peripheral can wake the MCU on threshold crossings, minimizing active time. Average current below 1 uA is achievable with duty-cycled measurements, delivering multi-year battery life on a 2400 mAh cell.

Portable Medical Monitoring Device
The 1.8 V to 5.5 V wide Vdd and on-chip op amps suit portable medical monitors such as pulse oximeters, glucose meters and blood-pressure cuffs. The PIC24FV16KM204-I/ML samples photodiode or bridge signals through its dual rail-to-rail op amps, digitizes via the 12-bit ADC, and stores calibration in the 512-byte EEPROM. The DAC drives a precision bias or audio cue. XLP technology keeps quiescent current low, extending battery life on AAA cells. The integrated op amps eliminate the need for separate analog-front-end ICs, reducing BOM cost and PCB area in FDA-cleared home-health products.

Industrial Sensor Conditioning and 4-20 mA Loop
Industrial sensors benefit from the PIC24FV16KM204-I/ML's wide 1.8 V to 5.5 V supply range, -40 C to +85 C industrial temperature grade, and integrated op amps for bridge and 0-10 V signal conditioning. A RTD or strain-gauge bridge is amplified by an on-chip op amp, the 12-bit ADC digitizes, and the MCU outputs a 4-20 mA loop signal via PWM plus a discrete DAC. The CLC provides fault detection combining comparator outputs. PPS lets engineers remap UART, SPI and I2C to any digital pin, simplifying mixed-signal industrial PCB layout and minimizing noise coupling into the analog section.

Smart Energy Meter and Submeter
The PIC24FV16KM204-I/ML is well suited to single-phase smart submeter designs with on-chip op amps handling current-sense and voltage-divider signals while the 12-bit ADC samples at 500 ksps. Real-time clock calendar with calendar mode timestamps consumption, and 2 KB SRAM buffers measurements between low-energy UART transmissions. 16 KB Flash holds the metrology code, display driver, and calibration data; 512-byte EEPROM holds tamper flags and lifetime counters. Wide Vdd tolerates rectified mains without level shifters, reducing BOM cost in metrology-grade consumer submeters.

Consumer HMI with Capacitive Touch
For low-cost consumer interfaces with capacitive touch buttons and an OLED or character LCD, the PIC24FV16KM204-I/ML integrates the op amps, comparators and PPS required to scan CTMU-based touch sensors while driving the display via SPI. The CLC peripheral combines comparator and timer signals to wake the MCU on touch events, then the SPI bus updates a small OLED graphic. Sleep current below 20 nA extends battery life in handheld remote controls, e-readers and IoT user interfaces that sit dormant between user interactions.

Automotive Body and Sensor Modules
Automotive body controllers and sensor modules leverage the PIC24FV16KM204 family for LIN-bus communication, sensor conditioning and actuator driving. The wide 5.5 V Vdd rail tolerates automotive load-dump and cranking transients when paired with proper TVS protection. On-chip op amps handle temperature, position and pressure sensor signals while the CLC generates timing debouncing of switch signals. EEPROM stores node configuration. For AEC-Q100 qualified variants in safety-relevant automotive designs, designers typically move up to the dsPIC33EP or PIC24HJ automotive families; the KM family serves non-safety body ECUs.

Portable Test and Measurement Instrumentation
Handheld multimeters, signal sources and cable testers benefit from the PIC24FV16KM204-I/ML's integrated op amps for input signal conditioning, dual 12-bit ADC channels for differential measurement, and PPS for flexible LCD and button scanning. The DAC drives a programmable reference voltage, while the UART outputs RS-232 / RS-485 via external transceivers. Wide Vdd supports 9 V battery through switching regulator rails, and XLP technology extends operating time in field-instrumentation use. Industrial -40 C to +85 C temperature grade supports outdoor deployment.

Ghi chú thiết kế
Use deep-sleep mode with RTCC active and external interrupts enabled to reach under 20 nA quiescent current on battery-powered IoT nodes. Wake only on a periodic RTCC alarm (typically every 1 to 60 s) or a sensor-triggered external interrupt, perform the ADC sample, then return to sleep. Decoupling: place a 0.1 uF ceramic + 1 uF tantalum within 5 mm of each VDD/VSS pair on the 44-QFN, and 10 uF bulk at board entry. Wide Vdd 1.8 V to 5.5 V tolerates a 2xAA alkaline pack across discharge profile without a switching regulator.
On the 44-QFN (8x8 mm) exposed-pad package, the central thermal pad must be soldered to the ground plane with a 5x5 grid of thermal vias (12 mil diameter, 8 mil plated) for heat dissipation and ground reference. Keep analog traces (sensor inputs, op amp I/O) at least 5 mm away from switching converter traces and oscillator traces to minimize capacitive coupling. Use a 4-layer PCB with a continuous ground plane under the analog section, and route op amp output traces directly to the dedicated ADC channel pins to avoid ADC switching charge kickback.
Do not exceed 5.5 V on VDD - the 'V' family supports wide Vdd but the absolute maximum is 5.5 V; if you need 6 V or higher rails, add a TVS diode and buck regulator. The PIC24F (non-V) variants top out at 3.6 V, so do not substitute a PIC24F16KM204-I/ML in a 5 V design without adjusting the power tree. The PPS peripheral requires that you explicitly assign every used peripheral signal to a physical pin via the RPINRx/RPORx registers; if you skip this step, all peripherals default to a single set of pins and code will not run as expected.
The on-chip 12-bit ADC achieves its 500 ksps throughput only with a low-impedance input source (< 2 kOhm) - use an external op amp follower stage or the integrated op amps in unity-gain buffer mode if your sensor has higher impedance. Add a 1 kHz RC anti-alias filter at the ADC input pin. For high-accuracy sampling, enable the ADC's early interrupt and DMA burst average mode; this improves SNR by 3 to 6 dB compared with single-shot conversions under noisy PCB environments.
