PIC24FJ128GL410-E/PT Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory (Flash/SRAM), and programmable peripherals around a common bus. The PIC24FJ family uses a 16-bit modified-Harvard architecture designed for embedded control, offering deterministic interrupt response, rich Core Independent Peripherals (CIPs), and a wide operating voltage range. The GL4 sub-family is the upper tier of the PIC24FJ line, scaling up to 512 KB Flash and adding dual-partition OTA updates and EEPROM emulation.
Key features of the PIC24FJ128GL410-E/PT include 128 KB Flash with error correction, 32 KB SRAM, hardware crypto engine support, real-time clock with calendar (RTCC), 12-bit ADC up to 500 ksps, multiple UART/SPI/I2C, USB 2.0 full-speed, and a Segment LCD driver. The CIPs include Configurable Logic Cells (CLC), Peripheral Trigger Generator (PTG), and DMA for offloading the CPU in signal-processing or motor-control loops.
The device operates from 2.0 V to 3.6 V with five low-power modes (Sleep, Deep Sleep, Idle, Doze, and Alternate Run) achieving sub-µA sleep currents. The 100-TQFP package exposes up to 85 I/O pins, supporting large display arrays or multiple sensor buses. Two 32-bit timers and a 16-bit timer base enable precise motor control, PFC, and lighting applications.
Typical applications include industrial HMI panels, smart thermostats, medical instrumentation, USB-connected point-of-sale terminals, secure IoT edge nodes, and segment-LCD based home appliances. The dual-partition Flash with live update supports Over-The-Air (OTA) firmware upgrades critical for deployed IoT fleets.
Designers should pay attention to decoupling: place 100 nF ceramic on each VDD/AVDD pair, route VBAT for the RTCC if used, and follow the package thermal guidelines for the 100-TQFP. The PIC24FJ GL4 family is supported by MPLAB X IDE, MCC (MPLAB Code Configurator), and a full software ecosystem for rapid prototyping.

Typical Applications
PIC24FJ128GL410-E/PT is suitable for 7 applications: Industrial HMI Panels, USB-Connected POS Terminals, Smart Thermostats with Segment LCD, Medical Infusion Pumps, IoT Edge Sensor Hubs, Smart Home Appliance Controllers, Industrial Motor Control (BLDC/PMSM).
Industrial HMI Panels
The PIC24FJ128GL410-E/PT drives industrial HMI panels with its integrated segment-LCD controller supporting up to several hundred segments, USB 2.0 Full-Speed for operator console connectivity, and 16-bit PMP for external graphics controllers. The 32 KB SRAM holds multi-language UI strings and Modbus RTU buffers, while the 32 MIPS CPU handles real-time touch response under 50 ms. Its -40 °C to +125 °C temperature range tolerates factory floor environments and its Dual Partition Flash enables secure remote firmware updates across a deployed fleet of HMI terminals.
Recommended
USB-Connected POS Terminals
The integrated USB 2.0 Full-Speed OTG controller with on-chip transceiver allows the PIC24FJ128GL410-E/PT to function as a USB device, host, or dual-role OTG node for POS terminal peripherals. The 128 KB Flash stores payment application firmware with cryptographic libraries, while 32 KB SRAM handles transaction buffers and USB descriptors. The Core Independent Peripherals (DMA, CLC) offload routine I/O tasks so the 32 MIPS CPU focuses on transaction logic and LCD display refresh.
Recommended
Smart Thermostats with Segment LCD
The PIC24FJ128GL410-E/PT drives wide-temperature range segment LCD glass for thermostat displays using its integrated charge pump and contrast control, eliminating external LCD bias components. The RTCC with VBAT maintains time-of-day during mains power loss, while five low-power modes achieve under 5 µA standby current for battery-backed operation. Dual Partition Flash enables safe OTA updates over Wi-Fi co-processors via UART or SPI, a critical feature for IoT thermostat fleets managed remotely.
Recommended
Medical Infusion Pumps
In medical infusion pumps the PIC24FJ128GL410-E/PT provides deterministic interrupt response and core independent safety peripherals that monitor flow rate and occlusion independently of the CPU. The 16-bit ADC and high-speed PWM enable precise motor control, while ECC Flash protects against bit-flip-induced dosing errors. The -40 °C to +125 °C temperature range, low-power modes for battery operation, and rich peripheral set allow FDA-cleared designs in compact form factors.
Recommended
IoT Edge Sensor Hubs
The PIC24FJ128GL410-E/PT serves as an edge sensor hub aggregating I2C/SPI sensor data and forwarding through USB or UART to a wireless co-processor. The DMA engine moves sensor data to RAM without CPU intervention, and the 32 KB SRAM buffers up to 1024 32-byte sensor samples. Dual Partition Flash enables OTA updates with zero downtime, critical for inaccessible edge installations. Five low-power modes reduce average current to under 100 µA for solar-powered deployments.
Recommended
Smart Home Appliance Controllers
Washing machines, refrigerators, and ovens use the PIC24FJ128GL410-E/PT to drive segment LCD user interfaces, sense temperature and motor position via the ADC, and communicate through USB service ports. The 32 MIPS CPU executes PID motor-control loops at 1 kHz update rates, while CLC peripheral implements hardware safety interlocks independently. The 128 KB Flash stores multi-cycle wash programs and self-diagnostic firmware, with OTA support for post-deployment feature additions.
Recommended
Industrial Motor Control (BLDC/PMSM)
The PIC24FJ128GL410-E/PT drives BLDC and PMSM motors using its high-resolution PWM, Quadrature Encoder Interface (QEI), and 32 MIPS CPU executing field-oriented control (FOC) algorithms. DMA offloads current-sense sampling, while the CLC generates hardware-defined overcurrent protection that shuts down the PWM within microseconds independent of CPU state. The 100-pin TQFP provides ample I/O for three-phase gate drivers, encoder feedback, and CAN or RS-485 communication for industrial networking.

Design Notes
Place a 100 nF X7R ceramic decoupling capacitor within 2 mm of every VDD/AVDD pin pair and a bulk 10 µF tantalum or ceramic capacitor at the regulator output. The PIC24FJ128GL410-E/PT is sensitive to VDD ripple below 3.0 V which may cause Flash programming errors. Route VDD and VSS on adjacent planes to minimize inductance; the GL4 family draws up to 60 mA during Flash writes.
Do not exceed 3.6 V on any I/O pin or supply rail - the PIC24FJ128GL410-E/PT is a 3.3 V part. MCLR must have a 10 kΩ pull-up to VDD and a 100 nF capacitor to ground for proper reset operation. The VBAT pin, if used for RTCC backup, requires a separate battery source; connecting VBAT directly to VDD disables the RTCC power-domain separation.
For 100-pin TQFP designs, use a 4-layer PCB with continuous power and ground planes under the IC. Route USB differential pair (D+/D-) as a 90-ohm differential with matched length within 150 mils. Keep crystal traces under 5 mm and surround them with ground guard rings to minimize EMI. The exposed thermal pad (EP) is not present on this TQFP variant but verify on the package drawing before layout finalization.
