PIC24EP512GU810 Overview
What is a 16-bit microcontroller? A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile working memory (SRAM), and a rich set of on-chip peripherals such as ADC, timers, communication controllers, and GPIO. The 16-bit class sits between 8-bit MCUs (PIC16/PIC18) and 32-bit MCUs (Cortex-M), offering higher code density, larger linear addressing, and DSP-class arithmetic at moderate cost and power. Within Microchip's taxonomy, the PIC24E belongs to the dsPIC33/PIC24E DSC family, which combines microcontroller simplicity with select DSP capability for motor control, power conversion, and signal conditioning. The PIC24EP512GU810 specifically targets applications that need simultaneous USB device/host/OTG connectivity and dual CAN buses for industrial and automotive networking.
Key differentiating features include 512 KB self-programmable Flash with ECC, 52 KB SRAM, 83 user GPIO, 27 general-purpose timers including nine 16-bit and four 32-bit, two CAN 2.0B modules, USB 2.0 FS OTG, a 12-bit 1.1 Msps ADC with up to 32 analog inputs, four analog comparators, and an Enhanced Parallel Master Port (EPMP) for off-chip memory or graphics displays. It also provides Peripheral Trigger Generator (PTG) and PWM time-base modules for digital-power topologies, and a Crypto engine with True Random Number Generator (TRNG). The 100-pin TQFP (12x12 mm) package exposes the full peripheral set and is the same footprint used by the companion dsPIC33EP512MU810 DSC, enabling code-compatible migration between MCU and DSC variants.
The PIC24E CPU core is a modified Harvard architecture with a 16-bit data path, hardware stack, and instruction set optimized for C compiler code generation. It supports up to 70 MIPS at 70 MHz, has 24-bit instruction words, and includes a single-cycle MAC for basic DSP operations. The device operates from 3.0V to 3.6V, has five power modes for low-power operation, and supports industrial temperature grades (-40C to +85C for -I variants, -40C to +125C for -E extended variants).
Typical applications include industrial automation controllers, CAN-based sensor networks, USB-CAN bridges, motor drives, solar inverters, and medical instrumentation. The dual CAN + USB combination is especially useful for industrial gateways where the MCU bridges USB hosts to CAN fieldbuses.
When designing with this device, verify that the 3.3V rail is clean; the MCU's high-speed ADC is sensitive to supply noise. Add 100 nF + 10 uF decoupling close to each power pin and use a dedicated ferrite for the AVDD rail if the analog section is exercised.

Typical Applications
PIC24EP512GU810 is suitable for 6 applications: Industrial CAN-USB Gateway, Motor Drive and Digital Power Control, Automotive Body and Chassis Networking, USB Medical Instrumentation, Solar Inverter and MPPT Controller, Display and HMI Controller.
Industrial CAN-USB Gateway
The PIC24EP512GU810's USB 2.0 Full-Speed OTG plus two independent CAN 2.0B controllers in a 100-pin TQFP make it an ideal bridge between a USB host (PC, HMI, or service tool) and a CAN fieldbus network. The 70 MIPS PIC24E core runs a full USB stack plus a CANopen or DeviceNet driver without offloading. Per Microchip's datasheet, the on-chip CAN controllers support CAN 2.0B active/passive filtering and ISO 11898-1 compliant bit timing; the 512 KB Flash and 52 KB SRAM comfortably hold USB CDC + CANopen stacks. The industrial -40C to +85C temperature grade is rated for control-cabinet deployment, while -E grade extends to under-hood and outdoor installations.
Recommended
Motor Drive and Digital Power Control
The PIC24EP512GU810 family datasheet specifies a high-speed PWM peripheral with up to seven duty-cycle generators, four analog comparators, and a Peripheral Trigger Generator (PTG) that together implement digital PFC, full-bridge, and LLC topologies. The 12-bit 1.1 Msps ADC with up to 32 channels is sufficient for multi-loop current/voltage sensing. The 100-pin TQFP exposes enough GPIO for independent MOSFET gate-driver signals. Engineers can keep control loops on-chip and use the on-chip 32-bit timers for deterministic PWM dead-band generation. Power dissipation is typically below 0.5 W even at 70 MIPS, so no heatsink is needed.
Recommended
Automotive Body and Chassis Networking
With two independent CAN 2.0B interfaces, USB OTG, 512 KB Flash and an AEC-Q100-qualified temperature grade (extended -E variant operating -40C to +125C per Microchip product page), the PIC24EP512GU810 is suitable for body-control modules, gateway ECUs, and CAN-to-LIN bridges. The PIC24E core's deterministic interrupt latency ensures that CAN message deadlines are met even under USB traffic. The 100-pin TQFP package exposes 83 GPIO for sensor inputs, actuator drivers, and LED matrix control. The on-chip 12-bit ADC reads battery voltage and sensor signals without external signal conditioning.
Recommended
USB Medical Instrumentation
The USB 2.0 Full-Speed OTG interface and 512 KB Flash allow the PIC24EP512GU810 to act as a tethered medical sensor front-end, streaming 12-bit ADC samples at up to 1.1 Msps to a host PC over USB. Per the Microchip datasheet, the ADC supports hardware oversampling for effective >14-bit resolution, suitable for ECG, pulse-oximeter, and blood-pressure front-ends. The dual CAN ports enable connection to bedside CAN networks. The industrial temperature grade and lead-free TQFP-100 package simplify IEC 60601-1 medical EMC compliance. The 52 KB SRAM buffers sample bursts without dropping USB packets.
Recommended
Solar Inverter and MPPT Controller
The PIC24EP512GU810 family datasheet documents dedicated PWM with PTG support for interleaved PFC and MPPT boost stages. The 12-bit ADC simultaneously samples PV string voltage, panel current, and grid voltage for the inverter control loop, while dual CAN interfaces report telemetry to a system controller. The 70 MIPS PIC24E core closes the MPPT loop in <1 ms, and 512 KB Flash accommodates lookup tables for partial-shading algorithms. The 100-pin TQFP package supports industrial temperature grade for outdoor inverter installations.
Recommended
Display and HMI Controller
The PIC24EP512GU810 integrates an Enhanced Parallel Master Port (EPMP) that interfaces to external graphics controllers or memory-mapped LCDs, combined with 83 GPIO for capacitive touch sensing. Per the datasheet, the EPMP supports 8-bit and 16-bit data widths with up to 23-bit address space, sufficient for character LCDs and small TFT panels. USB OTG enables host-mode file/USB-HID operation for HMI panels. The 512 KB Flash stores graphical assets, multi-language strings, and a small embedded GUI. Industrial -40C to +85C grade supports factory-floor HMI installations.

Key Differentiators

- True 16-bit deterministic core for industrial real-time control (vs STM32F407VGT6 (LQFP-100))
- Same package with two temperature grades (-I industrial / -E extended) (vs PIC24EP512GU810-I/PT vs PIC24EP512GU810-E/PT)
Design Notes
The PIC24EP512GU810 operates from 3.0V to 3.6V on VDD and requires a separate AVDD for analog rails. Per Microchip's datasheet, place a 100 nF ceramic + 10 uF bulk capacitor within 5 mm of each VDD/VSS pair, and a ferrite bead between VDD and AVDD with 100 nF + 10 uF caps on AVDD to keep ADC noise below 1 LSB at 1 Msps. Estimate: at 70 MIPS the core draws ~50 mA; total board current is ~80 mA with peripherals active.
The 100-pin TQFP requires 0.4 mm pitch traces; use a 4-layer PCB with a continuous ground plane beneath the MCU. Place the 7.3728 MHz or 8 MHz primary crystal within 5 mm of OSC1/OSC2, with a 1 kohm feedback resistor across the oscillator pins and 10-22 pF load caps to ground (per Microchip oscillator guidelines). Route the USB D+/D- lines as a 90-ohm differential pair, length-matched to within 150 mil, and place the 15 kohm pull-down on D- at the connector.
Do not exceed 3.6V on any pin, including MCLR. The PIC24E core is a 3.3V-only part and is NOT 5V tolerant - level-shift any 5V logic signals with a 4.7 kohm divider or external level translator. Do not enable the USB module without a valid VBUS present or with VUSB un-bypassed (1 uF cap required). Per the datasheet, ensure the FWDT postscaler is configured to prevent unwanted reset during long interrupt-disabled sections.
Estimated: at 70 MIPS CPU clock with all peripherals active, the PIC24EP512GU810 dissipates ~250 mW. The 100-pin TQFP has a theta_JA of approximately 45 C/W on a 4-layer board with copper pour, giving a 11C rise above ambient - well within the 125C junction limit. No heatsink is needed even in enclosed industrial housings. For -E extended temperature operation (-40C to +125C), keep ambient below 110C to maintain adequate margin.
Compliance Information
RoHS and REACH compliant per Microchip product page. -E extended temperature variants are AEC-Q100 qualified for automotive use. Lead-free TQFP-100 package.
