MPN: PIC24FJ128GA410-I/PT ✓ פעילPIC24FJ128GA410-I/PT סקירה
A 16-bit MCU is a microcontroller whose data path and registers are 16 bits wide, offering a balance between the simplicity of 8-bit MCUs and the throughput of 32-bit parts. The PIC24F family sits in the microcontroller -> embedded controller -> semiconductor hierarchy and is widely adopted where low power, deterministic interrupt response, and rich analog integration are required. The XLP technology in the PIC24FJ128GA410 adds deep-sleep currents below 1 uA with retention, real-time clock, and LCD bias generation all active.
Key features of the PIC24FJ128GA410 include hardware crypto acceleration for AES/SHA, dual-partition Flash with live update support, CTMU for capacitive touch and slope-compensation, a segmented LCD driver, and a Parallel Master Port (PMP) for external bus expansion. The device integrates CTMU, DMA, and an 8-channel hardware crypto engine that offloads authentication, encryption, and hashing from the CPU, freeing cycles for application logic.
The PIC24FJ128GA410 uses a modified Harvard architecture with separate program and data buses, allowing simultaneous instruction fetch and data access for sustained 16 MIPS throughput. The dual-partition Flash enables fail-safe firmware updates - one bank runs while the other is reprogrammed - and the eXtreme Low Power technology, combined with peripheral modules that can run in sleep, makes the part attractive for medical, metering, and secure IoT edge nodes.
Typical applications include secure IoT edge nodes, smart energy meters with LCD readout, medical devices such as glucose meters, white goods, point-of-sale terminals, home automation HMIs, and industrial control panels. The integrated LCD driver eliminates an external LCD bias generator, and the crypto module addresses designers who need authenticated firmware and secure communication without an external secure element.
When designing with this device, allocate PCB area for the segmented LCD glass routing early - the LCD pin assignment constrains the PCB layout more than the digital peripherals. Also note that the I/PT suffix denotes the industrial temperature grade (-40C to +85C), 100-pin TQFP, tray packaging.

יישומים טיפוסיים
PIC24FJ128GA410-I/PT מתאים עבור 6 יישוםs: Secure IoT Edge Nodes, Smart Energy Meters with LCD, Medical Devices (Glucose Meters, Patient Monitors), Home Appliance HMI Panels, Industrial Control Panels with Display, Point-of-Sale Terminals.
Secure IoT Edge Nodes
The PIC24FJ128GA410-I/PT fits secure IoT edge nodes because its integrated hardware AES/SHA crypto engine offloads authentication and TLS handshakes from the 32 MHz CPU, while XLP deep-sleep currents below 1 uA allow years of battery life on a single coin cell. Placed as the main MCU connected to a sub-GHz or BLE radio via SPI/UART, the device runs the application logic in active mode and wakes only on sensor or radio interrupts. Dual-partition Flash supports fail-safe over-the-air firmware updates, an essential requirement for deployed IoT nodes. The 16 MIPS throughput at 3.3 V is sufficient for local data aggregation, sensor fusion, and encrypted telemetry.
מומלץ
Smart Energy Meters with LCD
The PIC24FJ128GA410-I/PT is purpose-built for smart energy meters because its integrated segmented LCD driver eliminates the external bias generator, and the hardware crypto engine supports authenticated meter readings and tamper detection. Operating from 2.0 V to 3.6 V, it connects directly to a 3.6 V lithium battery backup that keeps the LCD active during line-power outages. The 32 MHz CPU at 16 MIPS handles metrology calculations, the segmented LCD updates up to 480 segments in real time, and dual-partition Flash enables remote firmware upgrades without service interruption. The 100-pin TQFP provides ample I/O for pulse inputs, communication ports, and metrology sensor interfaces.
מומלץ
Medical Devices (Glucose Meters, Patient Monitors)
The PIC24FJ128GA410-I/PT serves portable medical devices such as glucose meters and patient monitors because XLP technology enables long battery life, the segmented LCD driver removes the need for a separate display bias IC, and the 12-bit ADC delivers accurate sensor readings. Placed as the central MCU with a 3.3 V regulated rail, it runs measurement, calibration, and LCD rendering in active mode and drops to sub-uA sleep between readings. The hardware crypto module can encrypt patient data stored in Flash for HIPAA-friendly designs, and the -40 C to +85 C industrial temperature grade supports a wide range of clinical and home environments.
מומלץ
Home Appliance HMI Panels
The PIC24FJ128GA410-I/PT is well suited to home appliance HMI panels such as washing machines, ovens, and dishwashers because the segmented LCD driver with up to 480 segments handles multi-digit displays and icons directly. The hardware crypto engine can authenticate replacement parts and prevent counterfeit consumables. Connected to capacitive touch via the CTMU peripheral, the 100-pin TQFP package provides enough I/O for buttons, encoders, relay drivers, and motor control PWM outputs. The 32 MHz CPU runs user-interface state machines and the 16 MIPS throughput is more than sufficient for typical HMI workloads.
מומלץ
Industrial Control Panels with Display
The PIC24FJ128GA410-I/PT fits industrial control panels that combine a segmented LCD with keypad, sensor inputs, and Modbus/serial communication. The hardware crypto engine protects configuration and calibration data stored in Flash, while the dual-partition Flash enables field firmware updates without process downtime. The CTMU peripheral implements capacitive touch keys for the front panel, the 12-bit ADC reads analog sensors, and the UART/SPI/I2C peripherals connect to industrial transceivers. The -40 C to +85 C industrial temperature range meets harsh factory-floor requirements.
מומלץ
Point-of-Sale Terminals
The PIC24FJ128GA410-I/PT serves point-of-sale terminals because the hardware AES/SHA engine accelerates encrypted PIN-pad and payment-card data, while the segmented LCD driver displays transaction amounts and prompts. The 100-pin TQFP package provides GPIO for keypad scanning, magnetic-stripe reader interfaces, and printer control. The 32 MHz CPU handles user-interface logic, and dual-partition Flash supports signed firmware updates mandated by payment-industry certification. The 2.0 V to 3.6 V supply range supports battery-backed operation during power transitions.

הערות תכנון
Route the segmented LCD signals (PORTF/PORTG/PORTH/PORTJ/PORTK/PORTL) with short, balanced traces and guard them from digital switching signals to minimize crosstalk on the LCD glass. Add 100 nF decoupling capacitors close to each VDD pin and a single 10 uF bulk capacitor near the AVDD pin for the ADC and LCD charge pump. Place the crystal as close as possible to OSC1/OSC2 and keep the traces short to avoid EMI.
Do not assume pin-for-pin compatibility with the PIC24FJ128GA310 or PIC24FJ128GA110 families - while the TQFP-100 pinout matches, peripherals such as the segmented LCD controller and dual-partition Flash are absent or different in those variants. Firmware using crypto APIs (AES/SHA) must be removed or guarded before porting to a non-crypto variant. Always verify the peripheral map against the datasheet DS30009992 before re-routing PCBs.
Estimated: at 32 MHz / 3.3 V active mode, the core current is approximately 8 mA, so total active power is about 26 mW. In XLP sleep with RTCC running, current drops below 1 uA, enabling years of battery life for metering applications that wake only on external interrupts. Configure the VREG and PMD registers to disable unused peripherals and maximize sleep duration.
When using the Parallel Master Port (PMP), keep address and data traces matched in length within 5 mm and use a ground plane reference to maintain signal integrity at 32 MHz. Route the ICD programming pins PGEDx/PGECx with a 4.7 kohm pull-up on MCLR and provide a 6-pin ICSP header that matches Microchip's programming specification for field updates.
