PIC24F04KA201-I/MQ - 16-Bit 32MHz XLP Microcontroller | Microchip
Référence : PIC24F04KA201-I/MQ ✓ ActifPIC24F04KA201-I/MQ Présentation
A PIC24 microcontroller is a compact embedded-processing device built around a 16-bit RISC architecture. PIC24 products combine program flash, data RAM, digital and analog peripherals, and low-power features on one integrated circuit. Within the broader semiconductor hierarchy, the PIC24F04KA201 belongs to the MCU, embedded-controller, and 16-bit flash-microcontroller families designed for compact control, sensing, and communication-oriented products.
The PIC24F04KA201 family emphasizes nanoWatt XLP technology for power-constrained and battery-powered equipment. Verified family information identifies 14-pin and 20-pin options, a 20 nA deep-sleep current claim, and low-power peripherals including DSBOR and DSWDT. The target PIC24F04KA201-I/MQ is the 20-VQFN option, combining 18 I/O pins with a small 5 x 5 mm footprint.
Key specifications include operation from 1.8 V to 3.6 V, a 32 MHz maximum device speed, 1.375K x 24 words of flash program memory, 512 x 8 bits of RAM, and a 10-bit ADC with a 500 ksps conversion capability. These resources support real-time control, analog measurement, communications, and user-interface functions while limiting board size and power consumption.
Typical uses include battery-operated sensor nodes, energy-harvesting equipment, compact industrial controls, and low-cost embedded products. The 18 available I/O pins can connect sensors, actuators, indicators, and serial interfaces, while the ADC supports analog measurements without requiring a separate converter. The small VQFN package also suits space-constrained handheld and wearable devices.
Designers should preserve the supply-voltage and decoupling requirements in the manufacturer datasheet, verify the exposed-pad layout and programming connections, and confirm peripheral pin multiplexing before layout release. The -I grade designation, package code, ADC requirements, and low-power state behavior should also be checked against the complete operating and absolute-maximum ratings.
This page combines the verified manufacturer and distributor data with application guidance, procurement context, and an honest compatibility review. It also distinguishes confirmed drop-in replacements from related devices that may require a different package, pin assignment, firmware revision, or board redesign.

Applications typiques
PIC24F04KA201-I/MQ convient pour 6 applications: Battery-Powered Sensor Node, Energy-Harvesting Controller, Compact Industrial Control Module, Low-Cost Data Acquisition Module, Energy-Efficient Wearable Controller, Low-Cost Embedded Control Product.
Battery-Powered Sensor Node
The PIC24F04KA201-I/MQ fits a compact, battery-powered sensor node because it combines a 1.8 V to 3.6 V operating range with nanoWatt XLP low-power features, including a family-reported 20 nA deep-sleep current claim. Its 10-bit ADC converts analog sensor signals at up to 500 ksps, while 18 I/O pins support the sensor, status indicator, and wake or control interface. Place the MCU in deep sleep between measurements to reduce average consumption, and use the 16-bit architecture and 32 MHz maximum speed when local filtering or control logic is required. Validate the sensor impedance, regulator dropout behavior, and wake-cycle timing in the final design.
Energy-Harvesting Controller
The PIC24F04KA201-I/MQ is suitable for energy-harvesting control because its supply range begins at 1.8 V and its PIC24F04KA201 family emphasizes nanoWart XLP operation for power-constrained equipment. The 32 MHz processor can manage intermittent energy, update nonvolatile state, and supervise sensors while the 4 KB program memory limits firmware to a focused control task. Its 512 bytes of RAM is adequate for compact buffering but not large working sets. The key design trade-off is that the MCU can remain active during frequent harvest events, so firmware should schedule the radio, ADC, and other loads around the available harvested energy instead of assuming continuous supply.
Compact Industrial Control Module
PIC24F04KA201-I/MQ can serve as the control core of a compact industrial module because it provides 18 I/O pins, a 10-bit ADC rated at 500 ksps, and up to 16 MIPS of 16-bit processing in a 5 x 5 mm VQFN package. Digital outputs can operate actuators or indicators, while analog channels monitor sensors and equipment condition. The small package preserves board area, but the exposed pad and 1.8 V to 3.6 V supply architecture require careful PCB layout and thermal planning. The 4 KB flash and 512-byte RAM favor compact supervisory logic rather than a large control loop, logging application, or protocol stack.
Low-Cost Data Acquisition Module
The PIC24F04KA201-I/MQ is appropriate for a small data-acquisition module that needs mixed digital and analog inputs without using a high-pin-count microcontroller. The 18 I/O pins can accommodate digital triggers, status lines, and serial communications, while the integrated 10-bit ADC supports sampling rates up to 500 ksps according to the verified product information. Its 32 MHz maximum speed provides enough throughput for acquisition sequencing and basic data processing, although 512 bytes of RAM requires careful buffering or streamed transfer. For higher precision, faster conversion, or larger sample buffers, select a higher-resolution or higher-memory MCU rather than treating this part as a universal measurement platform.
Energy-Efficient Wearable Controller
PIC24F04KA201-I/MQ is well matched to a space-constrained wearable controller because its 20-VQFN 5 x 5 mm package combines 18 I/O pins with low-voltage operation and XLP power-management features. The 10-bit ADC can monitor a physiological or environmental analog input, while the 16-bit CPU handles control logic between long sleep intervals. The small footprint leaves room for a sensor and battery, but the available 4 KB of flash and 512 bytes of RAM require disciplined firmware sizing. Review startup currents, ADC reference accuracy, exposed-pad soldering, and the wearable enclosure's heat path before production release.
Low-Cost Embedded Control Product
PIC24F04KA201-I/MQ works as the primary controller in a low-cost embedded product combining local I/O, analog measurement, and modest control logic. Its 16-bit PIC RISC architecture and 32 MHz maximum speed are more capable than a basic 8-bit controller, while the 4 KB program-memory limit keeps the device aimed at focused appliances, accessories, and compact peripherals. Eighteen I/O pins reduce the need for an I/O expander, and the integrated ADC supports analog front ends. Because the 512-byte RAM is modest, use interrupt-driven or streaming designs and avoid large buffers; confirm package pin multiplexing and programming requirements in the manufacturer datasheet.

Notes de conception
Use the manufacturer land pattern for the 20-VQFN 5 x 5 mm exposed-pad package and verify the exposed pad's electrical connection before routing. Keep the exposed-pad thermal and electrical requirements consistent with the datasheet rather than treating it as an optional copper feature. Place input and output decoupling capacitors close to their intended pins, provide a continuous ground reference beneath and around the device, and avoid long return paths beneath switching nodes. The supplied excerpts do not contain a verified pin-number map, so do not finalize routing or pad connections from this product record alone.
Design the supply for the verified 1.8 V to 3.6 V operating range and account for the MCU's 32 MHz operating condition as well as sleep current. The family's 20 nA deep-sleep figure is not the complete application consumption: sensor leakage, pull resistors, regulator quiescent current, ADC references, and wake-cycle averages can dominate a battery design. Use measured duty-cycle estimates and confirm brownout, startup, and regulator-dropout behavior before relying on the headline sleep-current value for battery-life calculations.
Do not assume that related PIC24F04KA201 or PIC24F04KA200 ordering codes are interchangeable with PIC24F04KA201-I/MQ. Package dimensions, exposed-pad connections, oscillator pins, programming pins, ADC channels, and peripheral multiplexing can prevent a hardware or firmware drop-in. Compare the exact suffix, complete pin table, package drawing, and programming specification. Also verify that a proposed replacement retains the required 1.8 V minimum operating voltage, 32 MHz maximum speed, 4 KB flash, 512-byte RAM, and 18 I/O assignments.
Informations de conformité
The verified excerpts do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for this orderable part. Compliance must be confirmed from Microchip Technology's current product documentation or declarations.
