PIC24FJ96GA008T-I/PT - 16-bit 16MHz 96KB Flash MCU | Microchip
MPN: PIC24FJ96GA008T-I/PT ✓ Hoạt độngPIC24FJ96GA008T-I/PT Tóm tắt
A microcontroller (MCU) is a single-chip computer that integrates a CPU, non-volatile program memory, RAM, and I/O peripherals. Within the semiconductor taxonomy, MCUs sit under microcontrollers -> integrated circuits (IC) -> semiconductors. The PIC24F family specifically targets low-power, mixed-signal embedded designs that require DSP-like throughput without the cost of a full DSP IC. The "FJ" subfamily indicates Flash program memory plus the nanoWatt Technology power-management features that allow deep sleep, sleep, idle, and doze operating modes for battery-driven applications.
Key features include up to 16 MIPS throughput, an 8-channel hardware DMA controller, a 16-channel 10-bit/12-bit ADC (depending on variant), two UART modules, two SPI interfaces, two I²C interfaces, parallel master port (PMP) for external bus attachment, five 16-bit timers, and a real-time clock and calendar (RTCC). Hardware capacitive touch sensing (mTouch) and a charge time measurement unit (CTMU) are integrated, eliminating the need for many external analog components in user-interface designs.
Typical applications include industrial control panels, USB Human Interface Devices (HID), general-purpose embedded computing, and low-cost graphical user interface (GUI) front ends. Designers leverage the 80-pin TQFP footprint for prototypes and small-to-medium-volume production where through-hole assembly is not required.
Design considerations: the 80-pin TQFP package (12 x 12 mm body, 0.5 mm pitch) requires careful PCB layout for decoupling and trace escape; six layers are recommended for dense signal routing. The -I temperature grade supports industrial environments (auto-grade variants exist in the wider family).

Ứng dụng tiêu biểu
PIC24FJ96GA008T-I/PT phù hợp cho 6 Áp dụngs: Industrial Control Panels (HMI), USB HID Peripherals, Capacitive Touch Keypad Controllers, Low-Power Data Loggers, Sensor Hub Modules with USB Connectivity, Educational & Hobby Embedded Boards.
Industrial Control Panels (HMI)
The PIC24FJ96GA008T-I/PT suits industrial HMI panels because its 80-pin TQFP exposes 69 I/O pins and integrates 96 KB Flash for storing graphics bitmaps, fonts, and Modbus/Profibus protocol stacks. With the on-chip CTMU and 12-bit ADC, the MCU reads up to 16 capacitive-touch buttons without external analog components. The industrial -40 to +85 °C range and 16 MIPS throughput allow real-time encoder feedback and 50 ms screen refresh cycles for 320x240 QVGA displays driven through the parallel master port (PMP). Reference companion parts include the PIC24FJ256GA110 for higher-resolution displays and the MCP23S17 for GPIO expansion.

USB HID Peripherals
The PIC24FJ96GA008T-I/PT integrates a USB 2.0 full-speed (12 Mbps) device/host/OTG controller with on-chip transceiver, eliminating the external ULPI PHY that competing designs require. 96 KB Flash holds the USB HID, CDC, and HID-MSC composite stacks with room for vendor-specific reports. The 8 MHz internal oscillator with 4x PLL provides a precise 48 MHz USB clock, reducing BOM cost. Pair with the MCP1625 boost regulator for Vbus when running from a single-cell Li-ion source.

Capacitive Touch Keypad Controllers
With the integrated CTMU (Charge Time Measurement Unit) and 12-bit ADC, the PIC24FJ96GA008T-I/PT supports up to 16 capacitive-touch keys without any external analog front-end. The 96 KB Flash holds the mTouch firmware library, custom gesture recognition code, and beep/LED feedback routines. Designers typically add the MCP23S17 to expand touch channels for slider or rotary encoders. The 16 MIPS throughput executes debounce and averaging in under 1 ms per channel.

Low-Power Data Loggers
Battery-powered data loggers benefit from the PIC24FJ96GA008T-I/PT nanoWatt Technology offering deep sleep currents below 50 nA and selective peripheral wake-up. The 96 KB Flash stores up to 8,000 12-bit ADC samples with timestamps from the RTCC peripheral, while the 8 KB SRAM buffers pre-compression data. The 8 MHz internal RC oscillator with 4x PLL allows the MCU to wake, sample, and return to sleep in under 5 ms. Typical battery life exceeds 3 years on 2x AA cells with hourly wake cycles.

Sensor Hub Modules with USB Connectivity
The PIC24FJ96GA008T-I/PT is a natural fit for USB-tethered sensor hubs that aggregate multiple I²C/SPI sensor streams. Two I²C buses and two SPI interfaces allow the MCU to manage redundant sensor paths while a third UART provides debug console access. The 96 KB Flash stores composite USB device firmware plus sensor fusion code. The 12-bit ADC and CTMU combined provide mixed-signal conditioning for thermistor and capacitive-level sensors. Pair with the MCP2221A for USB-to-UART converter in production tester fixtures.

Educational & Hobby Embedded Boards
Hobbyists and educators favor the PIC24FJ96GA008T-I/PT because it combines 96 KB Flash, 8 KB RAM, and a full peripheral set (UART, SPI, I²C, USB, ADC, PWM) in a breadboard-friendly 80-pin TQFP (12x12 mm) on widely-available breakout boards. The MPLAB X IDE free toolchain and XC16 compiler make it a low-cost teaching platform for 16-bit MCU concepts. Reference books such as "Programming 16-bit Microcontrollers in C" use this part as the canonical example. The industrial -40 to +85 °C range allows student projects to graduate to commercial products without redesign.

Ghi chú thiết kế
Estimated: at 16 MIPS, 3.3 V supply, the PIC24FJ96GA008T-I/PT typically draws 18-22 mA. Place a 10 µF bulk tantalum capacitor plus a 0.1 µF ceramic decoupling capacitor at each VDD pin, located within 5 mm of the pin. Use a separate AVDD trace filtered through a ferrite bead to keep digital switching noise out of ADC conversions. For USB self-powered designs, VBUS must be monitored by an internal comparator per the manufacturer datasheet.
The 80-pin TQFP (12x12 mm body, 0.5 mm pitch) requires 4 mil traces and 4 mil spaces on 4-layer FR-4 with a continuous ground plane on layer 2. Fan-out from the inner leads should escape between the package and a 0.4 mm via-in-pad pattern for clean signal paths. Place the crystal within 5 mm of OSC1/OSC2 and surround it with a ground guard ring tied to VSS. Estimate: total decoupling capacitor footprint = 12 caps under the package body.
Do not exceed 3.6 V on any VDD or AVDD pin or the USB transceiver will be damaged. The CTMU requires explicit calibration at production via the mTouch library; skipping this step causes unreliable touch readings. Avoid using the JTAG pins (PGEDx/PGECx) as GPIO unless JTAG is disabled in the configuration bits, or the debugger will lose connectivity. The MCLR pin must have a 10 kΩ pull-up to VDD to ensure proper reset behavior.
Route the USB D+ and D- traces as a 90-ohm differential pair with length matching within 2 mm, keeping them away from any switching node or oscillator traces. The parallel master port (PMP) data and strobe lines should be length-matched to within 10 mm if driving a QVGA display at 16 MHz. Estimate: PMP at 16 MHz typically tolerates 50 mm trace length without termination on FR-4. Keep analog traces on layer 1 only and do not cross digital traces on adjacent layers without a continuous ground reference.
