PIC24EP512GU810-I/PF Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a configurable set of peripherals on one silicon die. Within the embedded system hierarchy, the PIC24EP512GU810 belongs to the 16-bit MCU category, sitting between 8-bit MCUs (PIC16/PIC18) and 32-bit MCUs (PIC32), and is optimized for applications that need more performance than 8-bit but not the cost of 32-bit cores. The 'PIC24E' family specifically targets digital signal control, motor control, and graphics user interface designs with its enhanced DSP engine and high-speed PWM peripherals.
Key features of the PIC24EP512GU810 include a 12-bit ADC with up to 24 channels and 500 ksps conversion rate, dual CAN 2.0B modules, USB 2.0 OTG with integrated transceiver, 10/100 Ethernet MAC, and nine 16-bit timers plus five 16-bit input capture and output compare modules. The 83 general-purpose I/O pins provide ample headroom for parallel display and keypad interfaces, while the dedicated peripheral pin select (PPS) feature allows flexible remapping of digital peripherals to any I/O pin.
The architecture combines a Harvard bus with a modified RISC instruction set, 16 working registers, and hardware multiply/divide, achieving 1.55 DMIPS/MHz. Internal oscillator options and a 4x PLL reduce external component count, while the on-chip 32 kHz low-power RC oscillator supports Real-Time Clock Calendar (RTCC) operation in sleep modes. Programmable Cyclic Redundancy Check (CRC) and a hardware crypto engine are integrated for data integrity and security in connected products.
Typical applications include industrial automation controllers, automotive body and infotainment ECUs, USB peripherals and HID devices, CAN-based sensor networks, and human-machine interface (HMI) panels with TFT LCDs. The combination of USB OTG and dual CAN in a single 100-pin package is particularly attractive for gateway nodes bridging CAN vehicle networks to USB host devices.
When designing with the PIC24EP512GU810, allocate decoupling capacitance close to every VDD/VSS pair and follow Microchip's TQFP-100 land pattern recommendations to maintain signal integrity on the high-speed ADC inputs. PGEC/PGD programming lines should be routed away from switching nodes to avoid programming crosstalk.

Typical Applications
PIC24EP512GU810-I/PF is suitable for 7 applications: Industrial CAN Gateway, USB HID Peripheral Controller, Automotive Body Control Module (BCM), HMI / TFT LCD Controller Board, Ethernet-Enabled Sensor Hub, Medical Monitoring Device, Motor Control with CAN Feedback.
Industrial CAN Gateway
The PIC24EP512GU810-I/PF is ideally suited for industrial CAN-to-USB gateways that bridge factory automation networks to host PCs or cloud edge gateways. The device integrates two independent CAN 2.0B controllers alongside a USB 2.0 Full-Speed OTG interface, eliminating the need for an external CAN-USB bridge IC and reducing BOM cost by approximately $2-3 per node. With 70 MIPS of processing throughput and 52 KB SRAM, the MCU can run a full CANopen or J1939 protocol stack while simultaneously serving a USB CDC or HID endpoint. The 12-bit ADC and 83 I/O pins support local sensor aggregation before transmission over the CAN bus.
Recommended
USB HID Peripheral Controller
For USB Human Interface Devices such as industrial keypads, custom input panels, or diagnostic tools, the PIC24EP512GU810-I/PF offers an integrated USB 2.0 OTG transceiver and full-speed PHY, removing the need for an external USB chip. The 512 KB Flash accommodates full USB HID stack plus application firmware, while the 83 I/O pins can scan large key matrices or drive LED indicators with PWM dimming. The 70 MIPS core is sufficient for debouncing, USB polling, and command processing without DMA offload. Operating from a single 3.3 V rail simplifies USB bus-powered designs.
Recommended
Automotive Body Control Module (BCM)
In automotive body control applications, the PIC24EP512GU810-I/PF (or its -E extended temperature variant) drives lighting, wipers, mirrors, and door modules via CAN bus. Dual CAN interfaces allow simultaneous connection to the powertrain CAN and body CAN networks, with hardware filtering reducing host CPU load. The 16-bit PWM outputs and 12-bit ADC support smooth motor control for window lifters and seat adjusters. The device's -40C to +85C industrial temperature range covers cabin environments, while the -E grade is required for under-hood modules. AEC-Q100 qualification applies to specific part numbers in the family.
Recommended
HMI / TFT LCD Controller Board
The PIC24EP512GU810-I/PF drives small-to-medium TFT LCD panels in HMI applications such as appliance control panels, medical instrument front panels, and industrial operator stations. The Peripheral Pin Select (PPS) feature allows flexible assignment of PMP (Parallel Master Port) data and control signals to any of the 83 I/O pins, simplifying PCB routing for 8-bit or 16-bit wide interfaces to common QVGA/WVGA displays. The 70 MIPS core handles graphics primitives, touch-screen scanning via the CTMU peripheral, and real-time UI updates. DMA channels offload display refresh to free CPU for application logic.
Recommended
Ethernet-Enabled Sensor Hub
With its integrated 10/100 Ethernet MAC and 512 KB Flash, the PIC24EP512GU810-I/PF can serve as a network-attached sensor hub in building automation or industrial IoT deployments. The MCU supports TCP/IP stacks (Microchip's MLA or third-party lwIP) and can aggregate data from multiple serial sensors before publishing to a Modbus TCP or HTTP endpoint. The Ethernet MAC requires only an external PHY (such as the DP83848) plus an RJ45 jack with integrated magnetics. The 83 I/O pins connect to UART, SPI, or I2C sensors while leaving headroom for status LEDs and configuration switches.
Recommended
Medical Monitoring Device
In portable medical monitoring devices such as pulse oximeters, blood pressure monitors, and glucose meters, the PIC24EP512GU810-I/PF provides the 16-bit signal processing precision needed for accurate sensor readings while maintaining low power consumption. The 12-bit ADC with 500 ksps oversamples photoplethysmogram (PPG) or ECG signals, and the DSP engine performs real-time filtering without external DSP chips. USB OTG enables easy charging and data transfer to clinical PCs. The 512 KB Flash stores both the application firmware and a USB MSD bootloader for field upgrades. Compliance with IEC 60601 requires careful PCB layout but the MCU itself is suitable.
Recommended
Motor Control with CAN Feedback
The PIC24EP512GU810-I/PF can drive small BLDC or stepper motors in networked industrial equipment such as robotic arms, conveyor diverters, and valve actuators. While not a dedicated motor-control part (that role belongs to the PIC24EP512MC series), the GU variant still provides nine 16-bit timers, five output compare modules, and 70 MIPS of DSP throughput for sensorless FOC algorithms on smaller motors under 200 W. Dual CAN reports motor telemetry back to a central controller while USB allows local tuning and firmware updates during commissioning. The 12-bit ADC samples back-EMF and current shunt signals at rates sufficient for 30 kHz PWM loops.

Design Notes
Decoupling: Place one 100 nF ceramic capacitor within 3 mm of every VDD/VSS pair on the TQFP-100 footprint. For the analog AVDD rail, add a 10 uF tantalum plus 100 nF ceramic in parallel to suppress ADC reference noise. The core and PLL have separate VDD pins (VDDCORE and VDDPLL) that must each be decoupled independently. Bulk 10 uF capacitance at the board input prevents USB inrush current from sagging the 3.3 V rail.
PGEC/PGD programming lines: Route the ICSP clock (PGECx) and data (PGEDx) lines away from switching nodes and high-current traces. Microchip recommends a 20 pF capacitor between PGEC and VSS as close to the chip as possible to mitigate cross-talk programming failures documented in the device errata. Keep the trace length under 50 mm if possible. The MCLR pin requires a 10 kohm pull-up and a 100 nF capacitor to VSS for in-circuit programming reliability.
Do not exceed 3.6 V on any digital or analog pin; the PIC24EP512GU810 is NOT 5 V tolerant on I/O. For designs migrating from older PIC24F parts, ensure any 5 V signal source uses a level translator or resistor divider. The USB D+/D- pins require a 15 kohm pull-down to maintain USB specification compliance when no host is present. Configuration bits (FICD, FOSC, FWDT) must be set correctly at the start of every firmware image; using the MCC default is the safest path for first-time designers.
The PIC24EP512GU810-I/PF is rated for industrial temperature -40C to +85C and typically dissipates under 200 mW in normal operation. At maximum core speed (140 MHz) with all peripherals active, power consumption rises to approximately 70-90 mA from VDD. The TQFP-100 package has a theta_JA of approximately 40 C/W, so a 10x10 cm four-layer PCB provides adequate cooling for industrial environments. For closed enclosures, calculate worst-case dissipation and provide ventilation or derate the CPU clock if temperatures exceed 70C ambient.
The 12-bit ADC achieves its specified 500 ksps performance only with careful analog front-end design. Use a low-pass RC filter (typically 1 kohm + 1 nF) on analog inputs to limit bandwidth to the Nyquist rate. The dedicated AVSS and AVDD pins must be tied to clean ground and 3.3 V respectively; do not share the analog ground return with high-current digital loads. For simultaneous sampling, ensure all four S&H channels see matched source impedance (typically < 1 kohm). Calibration via the ADC's internal bandgap reference should be performed at operating temperature for absolute accuracy.
Compliance Information
RoHS and lead-free confirmed per Microchip product page. The -I/PF is industrial grade; the -E/PF is extended temperature but still not AEC-Q100 qualified - for AEC-Q100, see the PIC24EP512GU810-H/PF or dedicated automotive part numbers.
