PIC24FJ48GA004-E/PT - 16-bit MCU 48KB Flash TQFP-44 | Microchip
MPN: PIC24FJ48GA004-E/PT ✓ Hoạt độngPIC24FJ48GA004-E/PT Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O. The PIC24FJ family sits in the 16-bit performance tier of Microchip's portfolio - more capable than 8-bit PIC16/PIC18 parts but simpler than 32-bit PIC32 or ARM Cortex-M devices. The 'FJ' suffix denotes the nanoWatt XLP (eXtreme Low Power) variants, designed for battery-powered and energy-harvesting applications where active current and deep-sleep current dominate battery life. PIC24FJ parts integrate USB, multiple serial interfaces, A/D converters, and RTCC on chip, reducing external component count versus 8-bit designs.
The PIC24FJ48GA004-E/PT executes instructions in a single cycle thanks to its modified Harvard architecture and 17x17 hardware multiplier, with a 32-bit by 16-bit hardware divider. The 'E' temperature grade (-40C to +125C) supports automotive under-hood and industrial environments where commercial-grade parts would fail. The /PT suffix indicates the 44-pin TQFP package on a tray, providing easy prototyping and rework versus QFN variants. Internal RC oscillators and the nanoWatt XLP power management unit enable flexible clocking without external crystals in many designs.
The PIC24FJ48GA004 belongs to the PIC24FJ64GA004 family and shares the same peripheral set: USB 2.0 full-speed OTG, multiple UART/SPI/I2C peripherals, a 10-bit A/D converter with up to 13 channels, five 16-bit timers, and a Real-Time Clock and Calendar (RTCC). The 48 KB Flash part differs from the 64 KB sibling only in program memory density - the peripheral set and pinout are identical, so 64 KB parts can be deployed on the same PCB layout when firmware grows beyond 48 KB.
Typical applications include industrial sensor interfaces, USB peripherals, low-power remote controls, handheld instruments, automotive body electronics, and battery-powered IoT edge nodes where the nanoWatt XLP feature set is valuable. The Explorer 16/32 development board PIM socket accepts this device directly, accelerating prototype bring-up.
When designing with this part, allocate the unused Flash area for a bootloader if firmware updates are anticipated. Ensure decoupling capacitors are placed within 5 mm of each power pin and that the VUSB pin has proper ESD protection if USB is enabled.

Ứng dụng tiêu biểu
PIC24FJ48GA004-E/PT phù hợp cho 6 Áp dụngs: Industrial Sensor Interface, USB Peripheral Device, Low-Power Remote Control, Handheld Test Instrument, Automotive Body Electronics, Battery-Powered IoT Edge Node.
Industrial Sensor Interface
The PIC24FJ48GA004-E/PT is well-suited to industrial sensor interfaces because its 10-bit ADC with up to 13 input channels captures analog signals from temperature, pressure, and flow sensors, while multiple UART/SPI/I2C peripherals connect to digital sensor buses. The 16 MIPS core handles real-time sensor fusion and protocol conversion without offloading to an external processor. The extended -40C to +125C 'E' temperature grade supports factory-floor cabinets and outdoor enclosures. Compared with an 8-bit PIC16 alternative, the PIC24FJ48GA004-E/PT adds single-cycle DSP-class math, larger 8 KB RAM for buffering, and on-chip USB for diagnostics logging directly to a host PC.

USB Peripheral Device
On-chip USB 2.0 Full-Speed OTG makes the PIC24FJ48GA004-E/PT ideal for USB peripherals such as data loggers, HID controllers, and CDC virtual COM port devices. Placing the MCU directly on the USB bus eliminates external bridge chips, reducing BOM cost and PCB area. The 16 MIPS core handles USB stack plus application code simultaneously, while the 8 KB RAM buffers USB packets without dropping frames. The nanoWatt XLP feature set enables suspend-mode current under 1 mA, helping USB peripherals meet the 2.5 mA suspend budget required by the USB specification for bus-powered devices.

Low-Power Remote Control
Battery-powered remote controls benefit from the PIC24FJ48GA004-E/PT nanoWatt XLP feature set, which delivers microamp-level deep-sleep current and multiple wake-up sources including RTCC alarm and external interrupts. The 32 MHz core wakes in microseconds to process button presses or RF commands, then returns to sleep, maximizing battery life on a coin cell or 2x AA pack. The on-chip RTCC maintains wall-clock time without an external crystal, further reducing BOM. Compared with 32-bit Cortex-M0 alternatives, the PIC24FJ48GA004-E/PT offers simpler firmware development in MPLAB X IDE and lower active current per MHz in typical applications.

Handheld Test Instrument
Handheld test and measurement instruments use the PIC24FJ48GA004-E/PT to drive LCDs, read rotary encoders, sample analog inputs, and communicate with host PCs via USB. The 35 digital I/O pins drive segment or graphical LCDs directly, while the 10-bit ADC digitizes sensor or measurement inputs. The 16 MIPS core executes control loops and display refresh without flicker, and 8 KB RAM buffers measurement histories for on-screen plotting. The -40C to +125C 'E' temperature grade ensures reliable operation in field service environments from cold outdoor sites to hot industrial plants.

Automotive Body Electronics
The extended -40C to +125C temperature grade qualifies the PIC24FJ48GA004-E/PT for automotive body electronics such as door modules, seat controllers, mirror adjusters, and ambient lighting. The 16 MIPS PIC24F core handles LIN or CAN-capable communication (with external transceiver) and PWM motor control outputs, while the 35 I/O pins drive LED arrays, relays, and H-bridges. Compared with commercial-grade 8-bit MCUs, the PIC24FJ48GA004-E/PT adds the thermal headroom required for under-hood and dash-mounted modules that experience sustained solar loading in summer operation.

Battery-Powered IoT Edge Node
IoT edge nodes deployed in remote locations rely on the PIC24FJ48GA004-E/PT nanoWatt XLP feature set to run for years on a single battery. The MCU spends most of its life in deep sleep at microamp current, waking periodically via RTCC or external sensor interrupt to take a measurement, transmit via UART-connected radio module, and return to sleep. The integrated 10-bit ADC captures sensor data without external components, and 8 KB RAM buffers aggregated samples before transmission. The Explorer 16/32 development board supports this device directly via a Processor Plug-In Module, accelerating prototype-to-production transitions.

Ghi chú thiết kế
The PIC24FJ48GA004-E/PT requires a bulk 10 uF decoupling capacitor near each VDD pin pair (VSS/VDD pins 15/16), plus a 0.1 uF ceramic high-frequency bypass within 5 mm of the supply pins. The VUSB pin (pin 29) requires its own 0.1 uF decoupling if USB is enabled, plus an external ESD protection array on D+/D- lines to meet IEC 61000-4-2 air-discharge ratings. Use a low-dropout regulator such as MCP1700 for the 3.3 V rail to keep sleep current low; the MCU draws less than 1 uA in deep sleep, but a noisy or high-quiescent LDO can dominate total sleep current.
Route the ICSP clock (PGEC, pin 17) and data (PGED, pin 18) traces as a matched pair to the debug header, keeping them away from switching noise sources. Place the crystal (if used) within 5 mm of OSC1/OSC2 (pins 8/7) with a grounded guard ring to reduce EMI coupling. The TQFP-44 thermal pad is not present on this part, but provide a copper pour on the top layer under the package connected to VSS to aid heat dissipation in high-MIPS continuous-run applications.
Do not assume pin-compatible migration from PIC24FJ64GA004 family to PIC24FJ64GA104 family without verifying peripheral pin assignments - the GA104 family uses a different pin mapping for SPI, I2C, and UART peripherals, even though both share the 44-pin TQFP footprint. Always lock the configuration bits in MPLAB XC16 to disable unused peripherals and pull-ups; otherwise floating inputs increase sleep current by 10-20 uA. Use the __builtin_disable_interrupts() and Idle() pattern for the lowest-power sleep mode entry; the SLEEP instruction alone does not turn off all peripherals.
For USB applications, route the D+ and D- lines as a 90-ohm differential pair with matched lengths, keeping them isolated from switching power traces by at least 3 mm. Place the USB connector shield to chassis ground through a ferrite bead plus 4.7 nF capacitor to provide ESD return path while preventing ground loops. The USB bus pull-up resistor on D+ (full-speed) connects to VUSB through a software-controlled pin; do not wire it permanently to VDD or the device will not enumerate correctly on bus reset.
