PIC24FJ64GP202T-I/MV Overview
A microcontroller (MCU) is a single-chip computer containing a CPU core, program memory (Flash), data memory (RAM), and integrated peripherals such as timers, ADCs, communication interfaces, and I/O ports. The PIC24FJ 'GP2/GU2' family sits within the broader taxonomy: microcontroller -> embedded processor -> semiconductor device. Its modified Harvard architecture and 16-bit data path place it above 8-bit MCUs in computational throughput while remaining lower in cost and power than 32-bit ARM Cortex-M devices for many real-time control tasks.
Key features include 64KB ECC Flash (22K x 24 words), 8KB SRAM, hardware Real-Time Clock and Calendar (RTCC), multiple 16-bit timers, a 10-bit ADC with up to 9 channels, and Core Independent Peripherals (CIPs) that offload tasks from the CPU. The integrated USB 2.0 Full-Speed transceiver with on-chip pull-up/pull-down resistors eliminates external USB components, while the eXLP sleep modes (Sleep, Deep Sleep, and VBAT) achieve nanoamp-level quiescent current for battery-powered designs.
The PIC24FJ64GP202T-I/MV is supplied in industrial temperature grade (-40C to +85C) on Tape and Reel. The 28-pin UQFN package with a 4x4 mm body suits space-constrained designs and provides an exposed pad for thermal dissipation. The 'T' suffix in the MPN denotes Tape and Reel packaging, while 'I/MV' denotes the industrial temperature grade and the UQFN-28 (MV) package.
Typical applications include USB HID peripherals, IoT sensor nodes, battery-powered data loggers, consumer health devices, industrial sensor interfaces, and USB-to-UART bridges. The combination of integrated USB, XLP sleep modes, and 16 MIPS performance makes it well suited to portable instruments and wearables. The Explorer 16/32 Development Board with PIC24F Plug-In Modules accelerates prototyping.
When designing with this MCU, ensure the exposed pad of the UQFN-28 package is soldered to a sufficiently large copper pour on the PCB for thermal relief and ground return. Decouple VDD/VUSB with 100 nF ceramic capacitors placed as close as possible to the supply pins, and follow the USB 2.0 Full-Speed differential pair routing guidelines (90-ohm differential impedance, matched length) when the USB D+/D- lines leave the board.

Typical Applications
PIC24FJ64GP202T-I/MV is suitable for 7 applications: USB HID Peripherals, Battery-Powered IoT Sensor Nodes, Industrial Sensor Interfaces, Portable Data Loggers, Consumer Health and Wearable Devices, USB-to-UART Communication Bridges, Educational and Prototyping Platforms.
USB HID Peripherals
The PIC24FJ64GP202T-I/MV's integrated USB 2.0 Full-Speed transceiver with Host/Device/OTG support makes it ideal for USB Human Interface Device peripherals such as keyboards, mice, game controllers, and custom HID input devices. The 16 MIPS performance handles USB protocol stack and HID report processing without external components. The 8 KB SRAM accommodates USB descriptor structures and HID report buffers. Place the MCU near the USB connector with the D+/D- differential pair routed at 90-ohm impedance, and add 100 nF decoupling on VUSB.
Recommended
Battery-Powered IoT Sensor Nodes
The eXtreme Low Power (XLP) sleep modes of the PIC24FJ64GP202T-I/MV achieve nanoamp-level quiescent current while retaining the full 8 KB SRAM, making it excellent for battery-powered IoT sensor nodes that wake periodically to take measurements and transmit data. The 64 KB ECC Flash stores wireless protocol stacks and sensor firmware, while the 10-bit ADC handles analog sensor readings. Connect a sensor to an ADC channel and a low-power radio module to a UART or SPI port. Use the RTCC for wake-up timing.
Recommended
Industrial Sensor Interfaces
The PIC24FJ64GP202T-I/MV's industrial -40C to +85C operating range and 16-bit processing make it well suited for industrial sensor interface modules including 4-20 mA loop-powered transmitters, RTD/thermocouple signal conditioners, and Modbus RTU nodes. The 10-bit ADC digitizes sensor outputs while the RTCC timestamps data. The integrated USB enables convenient configuration via USB-to-UART CDC mode. Use a TVS diode on the USB lines and isolated USB for industrial noise immunity.
Recommended
Portable Data Loggers
The combination of 64 KB Flash, 8 KB RAM, integrated RTCC, and eXLP sleep modes makes the PIC24FJ64GP202T-I/MV an excellent choice for portable data loggers that record sensor data at scheduled intervals over weeks or months on battery power. Store time-stamped samples in the Flash memory or an external EEPROM. Use the RTCC alarm to wake the MCU from deep sleep. The USB interface enables quick data offload to a PC without removing the SD card or EEPROM.
Recommended
Consumer Health and Wearable Devices
The PIC24FJ64GP202T-I/MV's XLP technology supports coin-cell battery operation in consumer health and wearable devices such as activity trackers, smart watches, and health monitors. Sleep currents in the nanoamp range enable multi-month battery life, while the 16 MIPS core handles heart rate calculation and display driving. The USB port enables charging and data sync without a dedicated programming interface. Connect a low-power OLED display via I2C and a heart-rate sensor via SPI.
Recommended
USB-to-UART Communication Bridges
The PIC24FJ64GP202T-I/MV can implement a USB CDC virtual COM port bridge to UART, SPI, or I2C peripherals, providing a compact and inexpensive USB interface for legacy or industrial equipment. The USB stack and CDC class driver fit comfortably within the 64 KB Flash, leaving room for application code. Operating at 16 MIPS ensures low-latency bridging without buffer overruns at common baud rates up to 921600 bps. The exposed pad of the UQFN-28 package requires a thermal ground pour on the PCB.
Recommended
Educational and Prototyping Platforms
The PIC24FJ64GP202T-I/MV's combination of USB, ADC, timers, and Core Independent Peripherals makes it a strong choice for educational kits and prototyping platforms teaching embedded systems, USB protocol, and low-power design. The Explorer 16/32 Development Board with PIC24F Plug-In Modules accelerates evaluation. The MPLAB X IDE and XC16 compiler are free downloads from Microchip. The 28-pin UQFN package is also available on the Curiosity Development Platform for rapid prototyping.

Design Notes
The UQFN-28 (MV) package has an exposed thermal pad (EP) on the underside that must be soldered to the PCB ground plane for both thermal dissipation and electrical ground return. Use a via array (0.3 mm vias on a 0.5 mm pitch minimum) connecting the EP to inner ground layers. Failure to properly solder the EP results in higher junction temperature and possible electrical malfunction. Place a 100 nF decoupling capacitor as close as possible to each VDD pin.
For USB 2.0 Full-Speed operation, route the D+ and D- traces as a 90-ohm differential pair with matched lengths (delta less than 150 mils). Place a 90-ohm common-mode choke near the USB connector for EMI suppression. Keep the D+/D- traces away from high-frequency switching nodes. The VUSB pin requires a 1 uF to 10 uF decoupling capacitor. Refer to the Microchip USB design guidelines for full layout recommendations.
For eXLP deep sleep operation, ensure all unused peripherals are disabled and all GPIO pins are configured as analog inputs or outputs driving defined logic levels. Floating inputs can cause supply current to increase by tens of microamperes per pin. Use the Peripheral Pin Select (PPS) feature to remap peripherals to available pins and minimize external component count. The RTCC can wake the device from deep sleep at programmable intervals.
Do not exceed the maximum VDD voltage of 3.6V on the PIC24FJ64GP202T-I/MV. The device is NOT 5V tolerant. When interfacing with 5V logic, use a level translator such as the TXS0108E or simple resistor dividers. The MCLR pin is active-low and must be pulled high through a 10 kohm resistor for normal operation; leaving MCLR floating can cause spurious resets. Configure the Configuration bits in your source code using #pragma config directives.
