PIC24EP512GU810T-I/PF Overview
A microcontroller (MCU) is an integrated circuit that combines a CPU, non-volatile program memory (typically Flash), volatile working memory (SRAM), and a configurable set of on-chip peripherals behind a unified bus architecture. MCUs sit one level above digital signal controllers (DSCs) in the embedded-processing taxonomy: PIC24E general-purpose MCUs are optimized for control and connectivity tasks, while dsPIC33E DSCs in the same package family add a DSP engine for high-throughput signal conditioning. The PIC24EP512GU810 belongs to Microchip's PIC24 power-management-aware MCU family, which includes GP (general purpose), MC (motor control), and GU (USB + graphics) variants sharing the same peripheral library.
Key features include a 32-channel 10/12-bit ADC with up to 1.1 Msps conversion rate, nine general-purpose 16-bit timers, nine Input Capture, nine Output Compare/Standard PWM, and additional dedicated High-Speed PWM with 7.14 ns resolution for digital power and motor control. The Peripheral Pin Select (PPS) remapping subsystem decouples peripheral signals from physical pins, simplifying PCB routing. A 15-channel DMA engine offloads data movement between peripherals and memory, freeing CPU cycles. An integrated hardware crypto engine, RTCC with calendar mode, and a parallel master port (PMP) for external graphics displays complete the integration.
The PIC24EP512GU810 employs a 16-bit modified-Harvard architecture with separate program and data buses, single-cycle hardware multiply, hardware divide, and a 24-bit instruction word. The 512 KB Flash supports live update through dual-partition Flash partitioning, and the 52 KB SRAM is large enough to hold TCP/IP stacks, USB HID/CDC class drivers, or graphic framebuffers without external memory. The wide I/O count (83 GPIO) and dual CAN interfaces allow the device to serve as a central node in industrial networks, automotive body controllers, or USB-equipped point-of-sale terminals.
Typical applications include industrial automation controllers, automotive infotainment and body-control modules, USB human-interface devices, barcode scanners and portable instrumentation, dual-CAN bridges, and battery-powered data loggers with USB charging. The combination of USB OTG and dual CAN makes it particularly attractive as a gateway between a USB host and a CAN-based vehicle or industrial bus. The industrial temperature grade allows deployment in factory-floor and outdoor enclosure designs.
When designing with this part, note that the supply voltage range is 3.0 V to 3.6 V and that careful analog supply decoupling is required to achieve the rated ADC performance. PPS pin assignments must be locked early in firmware development because not all remappable functions are available on every pin, and the high-speed PWM and RTCC functions draw on dedicated oscillators that must be enabled via configuration bits.

Typical Applications
PIC24EP512GU810T-I/PF is suitable for 7 applications: Industrial Automation Controller, Automotive Body Control Module, USB Human Interface Device (HID), Dual-CAN Gateway / Bridge, Battery-Powered Data Logger with USB Charging, Graphical Display Controller (PMP), Medical Point-of-Care Instrumentation.
Industrial Automation Controller
The PIC24EP512GU810T-I/PF serves as a central node in factory-automation cells because its 83 GPIO, dual CAN 2.0B modules, and 512 KB Flash handle large ladder-logic and motion-control firmware with headroom. Its 60 MIPS throughput is sufficient for closed-loop PID control of multiple axes while the 32-channel 10/12-bit ADC at 1.1 Msps samples current and voltage feedback with sub-microsecond latency. The wide 3.0-3.6 V supply tolerates industrial 24 V rails stepped down through standard linear or switching regulators, and the industrial -40C to +85C grade supports unheated factory-floor enclosures.
Recommended
Automotive Body Control Module
The PIC24EP512GU810T-I/PF integrates dual CAN 2.0B buses that map directly to automotive body and chassis networks, while 52 KB SRAM holds CAN message buffers and OSEK/Autosar-compatible stacks without external memory. Its USB 2.0 FS OTG port enables diagnostic logging and firmware update via a service-tool USB stick. The 16-bit modified-Harvard core with hardware multiply and divide delivers deterministic interrupt latency for body-control tasks such as door-lock coordination, lighting PWM, and LINbus sensor aggregation through the integrated LINbus peripheral.
Recommended
USB Human Interface Device (HID)
The integrated USB 2.0 FS OTG controller with on-chip PHY eliminates the need for an external ULPI bridge, shrinking PCB area for keyboards, barcode scanners, and programmable industrial keypads. The 512 KB Flash hosts USB HID class drivers and customer firmware, while 52 KB SRAM holds HID report buffers and a small RTOS for debouncing and LED control. PPS pin remapping brings D+/D- to convenient board edges without redrawing the schematic, and the 60 MIPS core delivers responsive HID polling above the USB 1 ms frame interval.
Recommended
Dual-CAN Gateway / Bridge
Two independent CAN 2.0B controllers allow the PIC24EP512GU810T-I/PF to act as a bridge between two CAN networks of different baud rates or protocols, filtering and forwarding messages between buses. The 15-channel DMA engine streams incoming CAN messages into SRAM buffers, freeing the CPU to apply translation rules, while 52 KB SRAM holds simultaneous buffers for both buses. Industrial -40C to +85C qualification supports both in-cabinet and outdoor enclosure deployments typical of building-automation gateways.
Recommended
Battery-Powered Data Logger with USB Charging
The 3.0-3.6 V single-rail supply suits the PIC24EP512GU810T-I/PF to 3.3 V Li-ion battery packs with USB charging, while the integrated RTCC with calendar mode provides accurate timestamping without external RTC chips. The 32-channel 10/12-bit ADC at 1.1 Msps samples multi-sensor inputs (temperature, voltage, current) with sufficient resolution for energy auditing, and 512 KB Flash stores weeks of compressed logs before offload via USB. Sleep modes with RTCC wake-up extend battery life between logging sessions.
Recommended
Graphical Display Controller (PMP)
The integrated Parallel Master Port (PMP) drives external graphical LCDs (QVGA, WQVGA) for industrial HMIs and medical instrument front panels without an external graphics controller IC. The 52 KB SRAM holds a partial framebuffer or a full small-resolution framebuffer, and the 7.14 ns High-Speed PWM module provides dimming control for the display backlight. The 16-bit modified-Harvard core with hardware multiply handles anti-aliased text and widget rendering at 60 MIPS, and USB OTG enables touch-panel coordinate upload during calibration.
Recommended
Medical Point-of-Care Instrumentation
The PIC24EP512GU810T-I/PF's 32-channel 10/12-bit ADC, dual CAN, and USB OTG combine to support compact benchtop analyzers that need multi-sensor acquisition plus PC connectivity for result upload. The 512 KB Flash stores calibration tables, firmware, and a USB CDC class driver for virtual-COM connectivity to host software, while 52 KB SRAM buffers streamed ADC data without dropping samples. The industrial temperature grade is sufficient for laboratory ambient, and PPS remapping simplifies routing of mixed analog and digital signals on a small PCB.

Key Differentiators
- Dual CAN plus USB OTG in the same TQFP-100 footprint (vs PIC24EP512GP206-I/PF)
- Drop-in upgrade path to DSC for signal processing (vs dsPIC33EP512MU810T-I/PF)
- Industrial-grade qualification in TQFP-100 (vs PIC24EP512GU810T-I/PT)
Design Notes
Decouple VDD/VDD2/AVDD separately. Place a 10 uF bulk capacitor near the VDD/VSS pins and a 0.1 uF ceramic per analog pair. AVDD must be tied to VDD through a ferrite bead for ADC noise rejection; sharing the same rail without isolation degrades ADC effective number of bits (ENOB) below the 12-bit rating. The USB transceiver analog supply (VBUS sense) draws up to 50 mA and must be sourced from the upstream 5 V through a regulator, not from VDD.
Estimated: at FOSC = 70 MHz, VDD = 3.3 V, and all peripherals active, core current consumption is approximately 60 mA. Power dissipation is therefore roughly 198 mW. With TQFP-100 theta_JA near 45 C/W on a 2-layer PCB, junction temperature rise above ambient is approximately 9 C - well within the 85 C industrial limit. For high-ambient enclosures (>60 C), use a 4-layer PCB with continuous ground plane to drop theta_JA below 30 C/W.
PPS pin selection must be locked early in firmware development because not every peripheral function is available on every GPIO. The PGECx/PGEDx ICSP pins are dedicated and cannot be remapped - reserve them on dedicated pads. The High-Speed PWM and RTCC each require their own secondary oscillator (POSC or SOSC) and cannot share FRC; enabling both without a dedicated crystal causes calibration drift. Configuration bits must be set before any PPS unlock - default reset state locks PPS until __builtin_write_OSCCONL sequence is issued.
Route the USB D+/D- traces as a 90 ohm differential pair with matched length within 150 mil. Keep the pair away from switching regulator inductors and high-current traces by at least 3 mm to avoid EMI coupling. For dual CAN bus designs, keep CANH/CANL traces short and route them as a 120 ohm differential pair; place the MCP2551 transceiver within 50 mm of the MCU CAN pins to minimize stub length.
Compliance Information
RoHS and REACH compliant per Microchip product page. The I grade is industrial -40C to +85C, not AEC-Q100 qualified; for AEC-Q100 automotive applications use a Q-grade variant.
