PIC24FJ128GB410-I/PT Présentation
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory, data RAM, and peripherals. The PIC24F family sits in Microchip's 16-bit MCU portfolio between 8-bit PIC18 and 32-bit PIC32MX/dsPIC devices, optimized for ultra-low-power and mixed-signal applications. Microcontrollers belong to the broader category of embedded processors and are the building blocks of nearly every electronic product, from battery-powered IoT nodes to industrial HMI panels.
Key features include 128 KB self-programmable Flash (43K x 24 instruction words), 16 KB SRAM, 4 KB auxiliary Flash for EEPROM emulation, hardware crypto engine, USB-OTG with PHY, segment LCD driver up to 128 segments, 4 UARTS, 4 SPI, 5 I2C, 16-bit timers, 12-bit A/D up to 1 Msps, and CTMU for capacitive measurement. The XLP technology enables nanoWatt deep-sleep currents as low as 20 nA in Sleep mode and 1.8 µA in RTCC mode, making it suitable for battery-powered designs.
The 16-bit modified-Harvard architecture with separate program and data buses enables deterministic interrupt latency and single-cycle 16-bit multiply, while the peripheral pin select (PPS) remapping subsystem simplifies PCB routing. The hardware crypto engine performs AES in 1.6 µs/MB and SHA-256 in 2.6 µs/block, offloading the CPU and reducing firmware complexity.
Typical applications include secure IoT sensor nodes, USB medical devices, secure access control, smart metering with LCD, industrial HMI, and battery-powered data loggers. The integrated USB-OTG PHY enables it to act as either USB host or device without external components.
Design consideration: route VDD/VSS pairs to each pin pair, place a 100 nF decoupling capacitor within 3 mm of every VDD pin, and connect the on-board 32 kHz secondary oscillator pins to a watch crystal for accurate RTCC. The Hardware Crypto module requires firmware initialization before use.
This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes that go beyond what the manufacturer datasheet alone provides.

Applications typiques
PIC24FJ128GB410-I/PT convient pour 6 applications: Secure IoT Sensor Nodes, USB Medical Devices, Secure Access Control and Smart Locks, Smart Metering with LCD Display, Industrial HMI Panels, Battery-Powered Data Loggers.
Secure IoT Sensor Nodes
The PIC24FJ128GB410-I/PT fits secure IoT sensor nodes because its integrated hardware crypto engine (AES, SHA-256) offloads TLS handshakes from the 16 MIPS CPU, while the XLP nanoWatt Sleep mode at 20 nA extends battery life to multi-year operation on two AA cells. The 100-pin TQFP exposes 5 I2C and 4 SPI buses, so engineers can connect multiple environmental sensors simultaneously. The 12-bit 1 Msps ADC and 3 comparators enable direct interface to analog sensor front-ends, and the on-chip USB-OTG PHY supports firmware updates over a wired connection. PIC24FJ128GA410-I/PT serves as a lower-cost sibling when hardware crypto is not required.
Recommandé
USB Medical Devices
The PIC24FJ128GB410-I/PT suits USB medical devices because the integrated USB-OTG full-speed PHY eliminates the need for an external USB transceiver, shrinking BOM cost and PCB area in compact handheld instruments. The hardware AES/SHA-256 engine secures patient data transmitted over USB to a host PC, meeting HIPAA-relevant encryption requirements. The 12-bit ADC with 1 Msps sampling captures bio-signal waveforms (ECG, pulse oximetry) with sufficient resolution for diagnostic algorithms. The industrial -40 to +85 C temperature range and 2.0 V to 3.6 V supply tolerate battery-powered operation. PIC24FJ128GB406-I/MR serves as a smaller-footprint 64-pin variant for ultra-compact probes.
Recommandé
Secure Access Control and Smart Locks
The PIC24FJ128GB410-I/PT fits secure access control systems because the hardware crypto engine accelerates AES authentication with RFID/NFC readers at the door, while segmented LCD driver (up to 128 segments) drives keypads and status displays directly without external driver ICs. The 32 kHz RTCC with crystal support tracks time-based access schedules, and the nanoWatt Sleep mode (20 nA) lets battery-powered locks idle for years. The 5 I2C instances handle multiple smart-card or BLE modules concurrently. The 100-pin TQFP provides enough GPIO for tamper switches, reed relays, and buzzer outputs. PIC24FJ128GA610-I/PT works as a lower-cost alternative when the LCD segment count is small.
Recommandé
Smart Metering with LCD Display
The PIC24FJ128GB410-I/PT fits smart electricity/water/gas meters because the integrated segment LCD driver (128 segments) directly drives the meter's display without a separate LCD controller, while the 12-bit ADC at 1 Msps accurately samples current shunts or pulse-output flow sensors. The XLP technology (20 nA Sleep, 1.8 µA RTCC) enables 10+ year battery life on a single lithium cell. The hardware AES-128 engine secures AMI (Advanced Metering Infrastructure) communications over PLC or RF links. The 16 KB SRAM buffers measurement data between transmissions. PIC24FJ128GA310-I/PT serves as a lower-pin-count variant for simpler meters.
Recommandé
Industrial HMI Panels
The PIC24FJ128GB410-I/PT suits industrial HMI panels because the 100-pin TQFP exposes enough GPIO for matrix keypads, LED status indicators, and segment LCD displays used in operator interfaces. The 4 UARTs handle multi-protocol fieldbus (RS-232, RS-485, Modbus RTU), and the 12-bit ADC reads analog sensor inputs from the controlled process. The hardware crypto engine secures over-the-air firmware updates, critical for field-deployed HMI equipment. The DMA (8-channel) offloads repetitive I/O tasks from the CPU, keeping the 16 MIPS core responsive to user input. PIC24EP512GP806-I/PT serves as an upgrade path for higher-performance HMI.
Recommandé
Battery-Powered Data Loggers
The PIC24FJ128GB410-I/PT fits battery-powered data loggers because XLP nanoWatt technology reduces Sleep current to 20 nA, allowing multi-year deployment on two AA cells when logging at hourly intervals. The 4 KB auxiliary Flash serves as EEPROM emulation for non-volatile configuration storage, while 128 KB main Flash holds the logger firmware and rolling buffers. The on-chip RTCC with 32 kHz crystal wakes the MCU at scheduled intervals, and the DMA channels move ADC samples to SRAM without CPU intervention. The hardware crypto engine secures logged data against tampering if the logger is recovered. PIC24FJ128GA110-I/PT serves as a smaller variant for low-channel-count loggers.

Notes de conception
Estimated: at 32 MHz core clock with all peripherals active, core current is approximately 19 mA at 3.3 V per Microchip datasheet DS30009983. Place a 100 nF decoupling capacitor within 3 mm of each VDD pin (9, 43, 70, 98) and a single 10 µF bulk capacitor near the MCU. Add a 10 µF + 100 nF pair on the USB VBUS rail if USB-OTG is used. The XLP nanoWatt Sleep mode drops current to 20 nA when peripherals are gated off.
Route the ICSP pair (PGECx/PGEDx) to a 6-pin header with series 4.7 kohm pull-up on MCLR to VDD. Place a 32.768 kHz watch crystal between SOSCI and SOSCO (pins 6 and 7) with 22 pF load capacitors to ground for RTCC accuracy. Use a continuous ground plane under the MCU; route USB D+/D- as a 90:100 ohm differential pair with no splits. Keep the analog AVSS/AVDD pair away from switching signals; the 12-bit ADC needs clean ground.
Do not skip the 100 nF decoupling on every VDD pin - 4 VDD pins means 4 capacitors, not 1. Do not connect USB D+/D- without the 90 ohm differential impedance; this degrades signal integrity and fails USB compliance. Configure the unused oscillator pins as digital I/O rather than analog to avoid excess current draw. Always init the Hardware Crypto engine before first use, and erase auxiliary Flash blocks before writing.
Informations de conformité
