PIC24FJ64GP202T-I/SS Overview
An MCU (microcontroller unit) is a single-chip computer containing a CPU core, program memory (Flash), data memory (SRAM), and on-chip peripherals such as ADCs, timers, and communication interfaces. MCUs sit at the heart of embedded systems, bridging sensors and actuators to firmware. PIC24F microcontrollers use a 16-bit modified Harvard architecture optimized for low-power deterministic control, hierarchical to dsPIC33 in performance and PIC16 in cost.
Key features include 22K x 24 Flash words with ECC, hardware Real-Time Clock and Calendar (RTCC) with calendar mode, four 16-bit timers, and Core Independent Peripherals (CIPs) such as Configurable Logic Cells and Multiple Output Capture/Compare/PWM (MCCP). The 28-SSOP industrial-grade package (-40C to +85C operating range) is tape-and-reel formatted with 2100-unit reels.
The PIC24FJ64GP202 family supports advanced peripherals including USB Full-Speed OTG in 'GP2/GU2' siblings, 12-bit ADC with up to 9 channels, comparators, and 5V-tolerant I/O on selected pins. Its eXtreme Low Power technology delivers sleep currents under 1 uA with full RAM retention, suitable for battery-powered IoT devices. Programming and debugging use MPLAB X IDE and PICkit/SNAP/ICD toolchains via 2-wire ICSP.
Typical applications include IoT sensor nodes, USB peripherals, industrial HMI, motor control, portable medical instruments, and battery-powered smart devices. The wide operating voltage and integrated peripherals eliminate external ADC and RTC chips, reducing BOM cost and PCB area in space-constrained designs.
Design tip: ensure decoupling capacitors of 0.1 uF and 1 uF are placed within 5mm of VDD/VSS pins. For USB applications, the GP202 family has Full-Speed USB on select variants; verify pin assignments in the datasheet before routing D+/D- traces with 90-ohm differential impedance.

Typical Applications
PIC24FJ64GP202T-I/SS is suitable for 6 applications: IoT Sensor Nodes, USB Peripherals (HID/CDC), Industrial HMI and Control, Portable Medical Devices, Battery-Powered Smart Devices, Motor Control and PWM.
IoT Sensor Nodes
The PIC24FJ64GP202T-I/SS suits IoT sensor nodes due to its XLP eXtreme Low Power technology delivering sub-uA sleep current while retaining the full 8KB RAM. Its 12-bit ADC accurately digitizes analog sensor outputs from temperature, humidity, and pressure transducers, while UART/SPI/I2C peripherals interface with sub-GHz radio or BLE modules. The 32MHz/16 MIPS core processes sensor fusion algorithms locally without external DSP chips, reducing BOM cost. Battery life on a CR2032 coin cell can exceed 5 years in duty-cycled applications where the MCU sleeps 99% of the time, with RTC wake-up at 1Hz intervals for periodic measurements.
Recommended
USB Peripherals (HID/CDC)
While the PIC24FJ64GP202 variant itself excludes USB, the GP2/GU2 family sibling PIC24FJ64GU205T-I/SS integrates Full-Speed USB 2.0 OTG directly, making the GP202 family ideal when migrating to USB-capable designs. The 32MHz core runs USB at 48MHz via PLL, supporting HID, CDC, and vendor-class devices without external USB chips. Internal pull-ups on D+/D- lines and 3.3V regulator output simplify BOM to just the MCU + connector + caps. The 64KB Flash accommodates USB stack plus application firmware, eliminating the need for external memory.
Recommended
Industrial HMI and Control
The PIC24FJ64GP202T-I/SS serves industrial HMI panels with its 21 I/O pins driving keypads, LED indicators, and character LCDs. Its 16 MIPS performance handles menu navigation and Modbus RTU protocol over UART for PLC communication. The 2.0-3.6V supply tolerates industrial 24V systems after regulation, and the -40C to +85C industrial temperature range handles factory floor environments. The 12-bit ADC reads potentiometers and analog sensors with 0.024% resolution, suitable for setpoint adjustment in process control loops.
Recommended
Portable Medical Devices
The PIC24FJ64GP202T-I/SS fits portable medical devices such as glucose meters, pulse oximeters, and wearable health monitors where low power and reliable operation are critical. Its XLP architecture with sub-uA sleep current extends battery life, while the 12-bit ADC accurately digitizes biosensor signals. The SSOP-28 package's small footprint suits compact wearables, and the industrial -40C to +85C range handles body-temperature variations. Microchip's medical-grade documentation and IEC 62304 support packages accelerate FDA submission cycles for Class II devices.
Recommended
Battery-Powered Smart Devices
The PIC24FJ64GP202T-I/SS excels in battery-powered smart devices including remote controls, wireless thermostats, and electronic shelf labels where the XLP sub-uA sleep current is the dominant design parameter. Its real-time clock and calendar (RTCC) with calendar mode wakes the device at scheduled intervals without external RTC chips, saving cost and PCB area. The 64KB Flash accommodates over-the-air (OTA) firmware updates via I2C/SPI bootloader, extending product life. A 2xAA alkaline battery pack typically delivers 10+ years of operation in duty-cycled applications.
Recommended
Motor Control and PWM
The PIC24FJ64GP202T-I/SS drives small BLDC and stepper motors through its multiple Output Compare and PWM peripherals with up to 6 channels at 32MHz. The 16 MIPS core executes FOC (field-oriented control) algorithms in real time, while the 12-bit ADC samples motor back-EMF for sensorless position detection. The 21 I/O pins handle Hall sensor inputs, fault indicators, and gate driver enables. The industrial temperature range and 2.0-3.6V supply tolerate motor-driver 24V rails after regulation, making the GP202 suitable for low-voltage fans, pumps, and small appliances.

Key Differentiators
- XLP eXtreme Low Power with sub-uA sleep current (vs PIC24FJ64GA102T-I/SS)
- Modern 12-bit ADC vs legacy 10-bit ADC (vs PIC24FJ64GA002-I/SS)
- USB-disabled 28-pin member of GP2/GU2 family (vs PIC24FJ64GU205T-I/SS)
Design Notes
Place 0.1 uF decoupling capacitors within 5mm of each VDD pin and a single 1 uF bulk capacitor near the package. The PIC24FJ64GP202T-I/SS requires VDD to stabilize within 2.0-3.6V; operation below 2.0V causes Flash read errors and Brown-Out Reset (BOR) events. For battery applications, use MCP1700 LDO with 1.6 uA quiescent current to preserve XLP sleep performance below 1 uA total.
Route the ICSP (ICSPand) pins RB6/PGC and RB7/PGD to a 2x3 0.1-inch header for PICkit/SNAP/ICD debugger access. Keep traces short (< 50mm) and avoid routing near switching power or RF lines. The SSOP-28 package pitch is 0.65mm - use 0.2mm trace/space rules at minimum. Add ground pour under the IC for thermal dissipation and EMI reduction.
Do not exceed 3.6V on any I/O pin - the PIC24FJ64GP202T-I/SS is NOT 5V tolerant except on I2C/SPI dedicated pins. Use level shifters when interfacing with 5V logic. Ensure the MCLR pin has a 10 kohm pull-up to VDD and a 100 nF cap to ground for clean reset; floating MCLR causes erratic behavior. Configuration bits must be set correctly for oscillator selection - failure to configure FOSC leaves the MCU in an undefined state.
Compliance Information
RoHS compliant per Microchip product page. Industrial temperature grade -40C to +85C; not AEC-Q100 qualified (use automotive PIC24 variants for AEC-Q100).
