PIC24FJ48GA002T-I/SS 개요
A 16-bit microcontroller is an embedded processor that fetches instructions from Flash, executes them on a wider datapath than an 8-bit MCU, and exposes on-chip peripherals such as ADC, timers, UART, I²C, SPI and PWM. PIC24F devices sit in the hierarchy: microcontroller -> embedded MCU -> 16-bit MCU -> PIC24F family -> low-power "nanoWatt" branch of Microchip's portfolio, targeting portable and consumer products where active MIPS-per-milliwatt efficiency matters.
Key features include a 16-channel 10-bit ADC with 500 ksps conversion rate, four 16-bit timers, two UART, two SPI and two I²C peripherals, a Parallel Master Port (PMP) for external graphics or memory, a Real-Time Clock & Calendar (RTCC), up to 21 GPIO, and the nanoWatt power-management modes (Sleep, Idle, Deep Sleep) that drop quiescent current into the microamp range. The integrated 8 MHz internal RC oscillator with PLL to 32 MHz eliminates an external crystal in many designs.
Architecturally, the device uses a modified Harvard core with separate 16-bit instruction and 8/16-bit data paths, hardware 17×17 multiply and 32/16-bit divide in one cycle, and a C-compiler-friendly orthogonal instruction set. Programmable peripherals are mapped through PPS (Peripheral Pin Select) on most PIC24F derivatives, easing PCB routing in the 28-pin footprint.
Typical applications include USB/USB-OTG device controllers (with the on-chip USB transceiver), portable medical and fitness instruments, smart energy and metering nodes, white-goods user interfaces, sensor hubs, and low-cost graphics HMI panels driven via the PMP bus. The wide -40 °C to +85 °C range also fits industrial sensing and motor control signal-conditioning front-ends.
When designing with the PIC24FJ48GA002T-I/SS, use MPLAB® X IDE plus MPLAB XC16 compiler for firmware, and target the Explorer 16/32 development board PIM socket for code bring-up. Leave a 4.7 µF bulk + 0.1 µF decoupling pair within 5 mm of VDD, and tie all unused I/O to defined logic levels to minimize Sleep-mode current leakage.

일반적인 애플리케이션
PIC24FJ48GA002T-I/SS 적합 용도: 6 애플리케이션s: USB HID / CDC Device, Portable Medical & Fitness Devices, Smart Metering & Energy Nodes, White Goods User Interface, Sensor Hub with Graphics HMI, Industrial Sensor Conditioning Front-End.
USB HID / CDC Device
The PIC24FJ48GA002T-I/SS integrates a USB 2.0 Full-Speed Device/OTG transceiver with on-chip pull-up resistors and 48 MHz-capable PLL, allowing designers to implement HID, CDC, MSD, or vendor-class USB devices with no external USB PHY. Its 48 KB Flash is enough for Microchip's USB stack plus application logic, while the 10-bit 500 ksps ADC handles analog sensors feeding the USB endpoint. Place a 0.1 µF decoupling capacitor within 5 mm of VDD, and use 90 Ω differential impedance on the D+/D- traces to meet USB FS signal-integrity requirements. The 16 MIPS CPU ensures comfortable headroom for USB polling plus control logic.

Portable Medical & Fitness Devices
The PIC24FJ48GA002T-I/SS is well suited to battery-powered medical and fitness products because its nanoWatt Sleep, Idle and Deep Sleep modes drop quiescent current into the microamp range, while the 2.0 V minimum VDD allows direct connection to a single Li-ion or two AA cells. The 10-bit 16-channel ADC with 500 ksps sampling supports heart-rate, SpO2, temperature and motion sensor front-ends; the integrated RTCC handles time-stamping and sleep scheduling. The 28-SSOP package keeps the BOM small and the 32 MHz core runs display refresh, BLE coordination via a UART-attached module, and signal-processing tasks comfortably.
추천
Smart Metering & Energy Nodes
The PIC24FJ48GA002T-I/SS provides the precision ADC, RTCC, and serial peripherals needed for residential smart-meter, submetering, or wireless sensor-node designs. Two UARTs run concurrent links to a PLC modem and a sub-GHz radio module, while two I²C channels attach EEPROM and energy-metering AFE chips. The 48 KB Flash fits metering firmware plus over-the-air upgrade bootloaders, and the 8 KB RAM absorbs measurement buffers. With the industrial -40 °C to +85 °C range and 3.6 V VDD tolerance, this MCU works inside sealed enclosures across mains-supplied or solar-battery deployments.
추천
White Goods User Interface
In washing machines, dishwashers, ovens and refrigerators, the PIC24FJ48GA002T-I/SS serves as the user-interface controller driving segmented LCDs via the on-chip PMP, scanning capacitive touch pads with the 10-bit ADC, and serializing control commands back to the appliance main MCU. Its 21 GPIO accommodate keypad rows/columns plus indicator LEDs, and the parallel master port streams display data without burdening the CPU. The 28-SSOP footprint is easy to drop onto appliance mainboards, and the industrial temperature range supports garage or unheated-room installations. The integrated RTCC maintains time-of-day for delayed-start cycles across power events.

Sensor Hub with Graphics HMI
The PIC24FJ48GA002T-I/SS combined with its parallel master port (PMP) drives small QVGA or WQVGA TFT panels, enabling sensor-hub designs that need a local graphical display. The 48 KB Flash and 8 KB RAM fit a lightweight graphics library plus protocol stacks (Modbus, I²C sensor aggregation), and the 16 MIPS CPU delivers smooth menu rendering. Up to 16 ADC channels aggregate analog sensors at 500 ksps total throughput, while SPI/I²C buses attach digital sensors and external memory. The result is a compact single-chip HMI controller for industrial monitors and bench instruments.
추천
Industrial Sensor Conditioning Front-End
For PLC analog-input cards, 4–20 mA loop receivers, or strain-gauge signal conditioning, the PIC24FJ48GA002T-I/SS digitizes bridge outputs through its 10-bit ADC, performs offset/gain compensation in firmware, and transmits calibrated readings via UART, SPI, or I²C to the host controller. The 2.0–3.6 V supply and industrial -40 °C to +85 °C rating ensure operation in factory cabinets. The PMP can drive status LEDs or a small character display, and the RTCC timestamps logged events. The nanoWatt Sleep modes minimize power when the loop is idle between samples.

설계 노트
Place a 4.7 µF bulk tantalum or ceramic in parallel with a 0.1 µF decoupling capacitor within 5 mm of the VDD pin, and replicate the same pair on AVDD when using the ADC. The PIC24FJ48GA002T-I/SS operates from 2.0 V to 3.6 V; running it from a switching regulator's output ripple (typically 30–50 mVpp) can couple into the ADC, so a low-noise LDO (e.g., MCP1700) between the switcher and VDD is recommended for precision analog designs.
Use 90 Ω differential impedance (±10%) on the USB D+/D- traces (RB5/RB6) and route them parallel with matched lengths and a continuous ground reference plane underneath. Keep USB traces short (≤ 50 mm), avoid splits in the ground plane, and add ESD protection (e.g., USBLC6-2SC6) at the connector. For programming, keep the ICSP PGEC1/PGED1 pair (RB1/RB0) accessible or expose a 5-pin ICSP header for production-line firmware update.
Do not leave any GPIO floating: tie unused pins to defined logic (VDD or VSS through 10 kΩ) to minimize Sleep-mode current leakage, which the datasheet (DS39763E) rates at < 1 µA only with all I/O terminated. Also note that the device's VUSB pin must be tied to VDD even when USB is unused; failing to do this can leave the on-chip USB transceiver in an undefined state. Finally, when migrating from PIC24FJ64GA004 to PIC24FJ48GA002, verify your linker script against the smaller 48 KB Flash window — code that fit comfortably on the 64 KB part may fail to link on the GA002.
The 28-SSOP package has a theta-JA of approximately 80 °C/W (per Microchip package thermal data), so at 32 MHz / 3.3 V the typical 15 mA active current (≈ 50 mW) raises junction temperature by only 4 °C above ambient — no heatsink needed. In Deep Sleep at < 1 µA, thermal concerns vanish entirely; verify that the chosen LDO's quiescent current (MCP1700 = 1.6 µA typ.) does not dominate the Sleep budget.
