PIC24FJ64GA004-E/ML - 16-bit MCU, 64KB Flash, 44-QFN | Microchip
MPN: PIC24FJ64GA004-E/ML ✓ Hoạt độngPIC24FJ64GA004-E/ML Tóm tắt
A 16-bit microcontroller (MCU) is a single-chip computer whose CPU datapath is 16 bits wide, sitting between 8-bit parts (PIC10/12/16, 8051, ATmega) and 32-bit parts (Cortex-M, PIC32). The PIC24FJ family uses a modified Harvard architecture with separate program and data buses, enabling single-cycle instruction fetch plus data access. The "FJ" suffix denotes the Flash-based variant with peripheral-rich general-purpose I/O, while "GA004" identifies the 28/44-pin pinout group with the USB-less analog-rich peripheral mix.
Key features include 64 KB (22K x 24) self-programmable Flash, 8 KB RAM, a 10-bit ADC with up to 13 input channels (model-dependent), up to five 16-bit timers, two UART, two SPI, two I²C, a parallel master port (PMP), and a real-time clock calendar (RTCC). An integrated 8 MHz internal RC oscillator with PLL provides 32 MHz system clock without external crystals in many designs. The 44-QFN package provides an exposed thermal pad that lowers junction-to-PCB thermal resistance, while the E-grade temperature range supports harsh-environment applications.
The PIC24FJ64GA004 uses Microchip's nanoWatt XLP (eXtreme Low Power) technology with multiple idle and sleep modes, deep sleep current in the nanoamp range, and on-chip voltage regulator. Its 16-bit core, deterministic interrupt latency, and dual-bus Harvard design deliver consistent execution time which is critical for real-time control loops. The 22K × 24-bit Flash word width is wider than 8-bit MCUs, allowing more efficient storage of constants and tables.
Typical applications include industrial control and HMI, low-power sensor nodes, USB-less embedded control, portable instrumentation, motor and lighting control, and consumer appliances that need more headroom than PIC16 but stay within a 16-bit architecture. The wide analog integration (ADC, comparators, CTMU) supports touch and signal-conditioning front-ends without external components.
When designing with this device, ensure the MCLR reset pin is pulled high through a 10 kΩ resistor and that Vcap (core regulator bypass) is decoupled with a 10 µF ceramic to ground; missing Vcap is a common bring-up failure. For low-power operation, select the deep sleep or retention modes and gate unused peripherals via PMD registers. Pin-compatible variants with different Flash/RAM density (PIC24FJ32, PIC24FJ128) exist in the same 44-QFN footprint for memory scalability.

Ghi chú thiết kế
Estimated: PIC24FJ64GA004-E/ML power at 32 MHz active mode draws ~15 mA at 3.3 V. Place a 10 µF ceramic capacitor on Vcap (pin 44) to ground within 5 mm of the pad - omitting this capacitor is the #1 bring-up failure mode. Add a 0.1 µF ceramic bypass on each VDD pin (15, 25, 42) within 2 mm of the package to suppress switching noise during PWM transitions. The internal 1.8 V LDO will not regulate without the Vcap bulk capacitor, causing erratic POR behavior.
MCLR (pin 41) must be pulled to VDD through a 10 kΩ resistor and decoupled with a 100 nF capacitor to ground - leaving MCLR floating causes spurious resets. JTAG pins (TCK/TDO) on RA4/RA5 should be left floating in production if unused, or pulled to known state to prevent injection of debug data on these pins. For low-power design, configure all unused I/O as outputs driving low (not high-Z) to minimize current leakage through the ESD diodes.
The 44-QFN (8x8 mm) package has an exposed thermal pad on the underside that MUST be soldered to a corresponding copper pad on the PCB for mechanical reliability and thermal dissipation. Recommended thermal pad is 5.5x5.5 mm with 9 thermal vias (0.3 mm drill) on a 1.0 mm grid connecting to the inner ground plane. Decoupling capacitors should be placed as close as possible to the VDD/VSS pairs along the package perimeter to minimize supply loop inductance.
