PIC24FJ64GU202T-I/SS 개요
A 16-bit microcontroller (MCU) is a microprocessor core with a 16-bit data path, embedded Flash program memory, RAM, and on-chip peripherals such as timers, ADC, communication controllers and interrupt logic. The PIC24F sits in the hierarchy: 16-bit MCU -> flash microcontroller -> embedded controller -> semiconductor. The PIC24FJ64GU202T-I/SS belongs to the PIC24F family that uses a modified Harvard architecture with a 24-bit instruction word and 16-bit data path, allowing single-cycle 16x16-bit multiply operations and a C-friendly runtime model.
Key features of this device include 64 KB (22K x 24) self-programmable Flash with error-correcting code, 8 KB SRAM, an integrated USB 2.0 Full-Speed On-The-Go transceiver, multiple UART/SPI/I2C peripherals, a 10-bit 1.1 Msps ADC, and the eXtreme Low Power (XLP) sleep architecture with retention. The 28-SSOP package exposes the USB D+/D- pins, two 16-bit timers, five 16-bit timers/counters, and up to 25 general-purpose I/O depending on remap configuration.
The CPU runs at 32 MHz with a 4-cycle pipeline, providing 16 MIPS throughput, while the Flash controller supports live updates via dual-partition Flash and ECC single-error correction/double-error detection. The CIP block includes configurable logic cells, a 32-bit CRC, and a hardware AES engine in higher family members; this variant focuses on USB + XLP + ADC for low-pin-count designs.
Typical applications include low-pin-count USB peripherals (HID, CDC, custom class), wearable health sensors, IoT edge nodes, industrial data loggers, and battery-powered instrumentation. The XLP sleep currents below 500 nA (RAM retention) make it well suited to coin-cell devices.
Designers should provide a stable 3.3 V rail, route the USB D+/D- pair as a 90 ohm differential, and reserve an ICP/ICD pin header for in-circuit programming. The T suffix indicates Tape-and-Reel, the I indicates the industrial -40C to +85C temperature range, and the /SS suffix identifies the 28-SSOP package. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.

일반적인 애플리케이션
PIC24FJ64GU202T-I/SS 적합 용도: 6 애플리케이션s: USB HID Peripheral (Keyboard / Mouse / Custom HID), Wearable Health & Fitness Sensor, Industrial Data Logger / Sensor Hub, IoT Edge Node with USB Provisioning, Battery-Powered Instrumentation, USB-to-UART / USB-to-SPI Bridge Device.
USB HID Peripheral (Keyboard / Mouse / Custom HID)
The PIC24FJ64GU202T-I/SS fits USB HID designs because the integrated USB 2.0 Full-Speed OTG transceiver eliminates an external PHY and the XLP sleep mode (sub-500 nA with RAM retention) allows battery-powered HID devices to idle for months. With 16 MIPS throughput and 64 KB Flash, the MCU comfortably runs Microchip's MLA USB stack with room for application-specific HID report descriptors and CPI logic. Placed on a small PCB with a USB-C or micro-B connector and ESD array, this part delivers a compact, low-power HID peripheral without external USB components.

Wearable Health & Fitness Sensor
For wearable designs the PIC24FJ64GU202T-I/SS delivers <500 nA sleep current while retaining 8 KB SRAM, enabling always-on sensor sampling at coin-cell energy budgets. The 10-bit ADC and I2C/SPI peripherals connect directly to optical heart-rate, temperature, and motion sensors, while 16 MIPS handles on-device filtering and BLE-beacon-like timing. The 28-SSOP package (5.30 mm body) fits compact wristband PCBs. Designers should route the USB pins to a debug cradle rather than wear-facing connector for size optimization.
추천
Industrial Data Logger / Sensor Hub
The PIC24FJ64GU202T-I/SS suits industrial sensor hubs because its industrial -40C to +85C range, 64 KB ECC Flash with error correction, and 10-bit ADC allow reliable long-term logging in factory environments. The USB OTG enables direct file extraction to a USB stick without an external bridge chip, while the CIP block handles deterministic sensor sampling without CPU load. With 8 KB SRAM, the MCU buffers moderate sample bursts before USB bulk transfer. Designers should add a TVS on VDD for surge protection on industrial 24 V-derived rails.
추천
IoT Edge Node with USB Provisioning
For IoT edge nodes the PIC24FJ64GU202T-I/SS provides USB for in-field provisioning, firmware update via USB mass storage class, and direct host communication with a phone or PC. The XLP architecture lets the node sleep below 500 nA between sensor reports while RAM retention preserves the network state. With 16 MIPS it handles lightweight MQTT-SN or proprietary RF-baseband control via SPI. The 28-SSOP footprint allows compact node PCBs that pair with wireless modules like Sub-GHz or LoRa transceivers.
추천
Battery-Powered Instrumentation
The PIC24FJ64GU202T-I/SS serves battery-powered instruments by combining USB (for charging/data export), a fast 10-bit ADC for measurement, and XLP sleep below 500 nA that stretches battery life to months. With 8 KB RAM and 64 KB Flash, the MCU runs calibration tables, linearization routines, and USB CDC virtual COM port firmware without external memory. Placed between a Li-ion cell and the measurement front-end, this part keeps the system idle-friendly while supporting instant USB tethering for field debugging.
추천
USB-to-UART / USB-to-SPI Bridge Device
The PIC24FJ64GU202T-I/SS is a natural fit for USB-to-UART or USB-to-SPI bridges because the integrated USB OTG replaces an external bridge chip (FTDI/MCP2221) and the multiple UART/SPI/I2C peripherals can be exposed as CDC or vendor-class endpoints. With 16 MIPS it handles protocol translation in real time without bottlenecks. The 28-SSOP package fits into a USB dongle form factor. Designers should add proper ESD protection on D+/D- lines and ensure the host enumerates within USB spec timing.

주요 차별점
- Integrated USB 2.0 Full-Speed OTG without external PHY (vs PIC24FJ64GP202T-I/SS)
- Extended temperature grade variant available in same footprint (vs PIC24FJ64GU202-E/SS)
- Lower power sleep current with RAM retention vs older PIC24F families (vs PIC24FJ64GA002-I/SS)
설계 노트
Estimated: at 32 MHz active and 3.3 V supply, core current is roughly 15 mA typical for the PIC24FJ GU2 family. For USB suspend compliance, the total system current must drop below 500 uA within 10 ms of USB suspend signalling - leverage the XLP sleep with peripherals off and RAM retention to meet this. Decouple VDD with 100 nF and 10 uF ceramic placed within 5 mm of the package pins; place a ferrite bead on the USB VBUS line to suppress upstream noise.
Route the USB D+/D- pair as a 90 ohm differential with matched length and continuous ground reference underneath. Place the ESD protection array (USBLC6-2SC6 or equivalent) within 5 mm of the USB connector, with short stubs to the MCU pins. Keep the ICSP header accessible (PGED1/PGEC1 on RB6/RB7 in this package) for in-circuit programming and debugging - do not route high-speed signals across these pins.
Do not exceed 3.6 V on any pin - the PIC24FJ is a 3.3 V part and 5 V tolerance is not guaranteed, which trips up designers migrating from PIC18F 5V-tolerant pins. Ensure the USB voltage regulator starts cleanly within 100 ms of VDD; a soft-start ramp can confuse the USB peripheral's PLL. Always connect both VDD pins (13 and 28) and both VSS pins (7 and 20) for proper current return, especially when USB is active at Full-Speed.
