PIC24FJ16GA004T-I/PT - 16KB Flash 16-bit MCU | Microchip
MPN: PIC24FJ16GA004T-I/PT ✓ نشطPIC24FJ16GA004T-I/PT نظرة عامة
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O onto one die. The PIC24F family sits in the 16-bit segment of the Microchip PIC portfolio, positioned between the 8-bit PIC16/PIC18 and the 32-bit PIC32MX. It uses a modified Harvard architecture with separate program and data buses, optimized for deterministic interrupt response and C-compiler efficiency. Within that hierarchy, the PIC24FJ16GA004T-I/PT is the 16 KB Flash, 44-pin variant of the GA004 family.
Key differentiating features include 35 general-purpose I/O pins, multiple analog and digital peripherals, the 4x PLL that lets the internal 8 MHz oscillator reach the full 32 MHz instruction rate, and C compiler optimization support that allows efficient use of the MPLAB XC16 toolchain. The 17-bit by 17-bit single-cycle multiplier accelerates DSP-class math.
Technical depth: the part uses a 5.5K x 24-bit Flash organization that gives a true 16 KB of linear instruction space, while 4 KB of RAM is split between general-purpose SRAM and the system stack. Hardware multiply/divide is single-cycle, and the 32 MHz core delivers 16 MIPS. A peripheral pin select (PPS) function allows many digital peripherals to be remapped to a wide choice of I/O pins, simplifying board layout.
Typical applications include industrial control panels, automotive body and HVAC modules (note: automotive grade requires special ordering codes per the Microchip product page), USB device or human-interface nodes using the on-chip USB transceiver on related GA004 family members, and low-cost general-purpose 16-bit embedded platforms. The automotive recommendation from Microchip makes it a candidate for non-safety in-cabin modules.
When designing with this MCU, ensure the JTAG/ICD interface is brought to a header for MPLAB ICD programming and debugging, and respect the 3.0 V to 3.6 V Vdd range. Pin-compatible migration paths exist within the PIC24FJ64GA004 family for users who later need more code space.

التطبيقات النموذجية
PIC24FJ16GA004T-I/PT مناسب لـ 6 التطبيقs: Industrial Control Panels, Automotive Body and HVAC Modules, USB Human-Interface Devices, Low-Cost 16-bit Embedded Platforms, Battery-Powered Sensor Nodes, Consumer Appliance Control.
Industrial Control Panels
The PIC24FJ16GA004T-I/PT is a strong fit for industrial control-panel HMIs and machine controllers because it provides 35 I/O, 16 MIPS of compute, and 16 KB of Flash at a price point typical of mid-range control nodes. Its 8 MHz internal oscillator with 4x PLL eliminates the need for external crystals on cost-sensitive panels, while 4 KB of RAM holds protocol stacks such as Modbus RTU. Industrial -40C to +85C operating temperature matches cabinet environments, and the 16-bit core can drive ADC sampling, PWM outputs, and UART-controlled peripherals concurrently.
موصى به
Automotive Body and HVAC Modules
The PIC24FJ16GA004T-I/PT is recommended by Microchip for automotive body and HVAC designs where AEC-Q100 is not required for the in-cabin module, or where the designer will order the automotive-grade ordering code. The PIC24F core delivers deterministic interrupt latency for switch debouncing and PWM fan control, while 16 KB Flash accommodates typical HVAC firmware plus a bootloader. Per the Microchip product page, special ordering codes for automotive-grade versions apply, so designers must use the correct part suffix when targeting AEC-Q100 production.
موصى به
USB Human-Interface Devices
The PIC24FJ16GA004T-I/PT integrates an on-chip USB 2.0 full-speed transceiver and SIE on the GA004 die, so it can present itself as a USB HID, CDC, or vendor device without an external PHY. The 16 MIPS core handles HID report parsing and LED animation concurrently, and 16 KB Flash fits the USB stack plus application code for keyboards, pointers, or custom peripherals. PPS allows flexible USB-D+/D- pin assignment for board routing around connectors.
موصى به
Low-Cost 16-bit Embedded Platforms
The PIC24FJ16GA004T-I/PT targets cost-sensitive embedded platforms that need 16-bit compute, generous I/O, and modern peripherals at the bottom of the PIC24F price stack. 35 I/O, 16 MIPS, 16 KB Flash, and 4 KB RAM cover generic sensor aggregation, low-rate data logging, and UI control tasks. The MPLAB XC16 C compiler optimization makes firmware portable across the GA004 family, easing code reuse on later designs.
موصى به
Battery-Powered Sensor Nodes
The PIC24FJ16GA004T-I/PT supports sleep and idle modes with low current draw, and its 2.0 V to 3.6 V Vdd range accepts a single Li-ion or two AA cells directly. The 17-bit single-cycle multiplier accelerates sensor-fusion algorithms for temperature, pressure, and humidity nodes, while 4 KB RAM accommodates smoothing filters and short event buffers. The internal 8 MHz oscillator removes the quiescent current of an external crystal, extending battery life.
موصى به
Consumer Appliance Control
The PIC24FJ16GA004T-I/PT fits white-goods and small-appliance control boards where 16 MIPS, 16 KB Flash, and 35 I/O deliver enough headroom for motor drivers, keypad scanning, and triac-based phase control. The industrial -40C to +85C grade handles kitchen and laundry environments, and the same TQFP-44 footprint is shared across the GA004 family so designers can drop in 32 KB or 64 KB Flash variants without PCB changes.

ملاحظات التصميم
The PIC24FJ16GA004T-I/PT operates from 2.0 V to 3.6 V on VDD. Decouple each VDD/VSS pair with a 100 nF ceramic capacitor placed within 2 mm of the pin, and add a bulk 4.7 uF to 10 uF capacitor near the MCU. If the ENVREG pin is used to enable the internal 3.3 V regulator for the USB transceiver, follow the datasheet's VBUS/VUSB decoupling recommendations to keep USB signal integrity within USB 2.0 full-speed specifications.
Route PGED1/PGEC1 (RB0/RB1) and PGED2/PGEC2 (RB2/RB3) to a 6-pin ICSP header with a 4.7 kohm pull-up on MCLR as required by MPLAB ICD programmers. Use keep-out zones around the crystal pins if you mount an external oscillator, and keep USB D+/D- traces matched within 2 mm and 4 pF of capacitance to comply with USB 2.0 full-speed signal-integrity requirements. The exposed pad on the QFN /ML variant must be soldered to the ground plane for thermal dissipation.
Do not assume the internal 8 MHz oscillator is precise enough for USB - the GA004 family requires the 4x PLL to reach the 32 MHz CPU clock but USB full-speed timing still needs the dedicated USB PLL configuration or a 48 MHz USB clock source. Programming voltage on MCLR must follow the ICSP spec; using a too-low Vpp during in-circuit programming is a frequent cause of verification errors. Also confirm the PPS configuration in __init() before relying on remapped peripherals, otherwise UART and PWM will not appear on the expected pins.
