PIC32MK1024GPE064-I/PT Overview
An MCU (microcontroller unit) is a self-contained computing subsystem that integrates a CPU core, program and data memory, non-volatile storage, and a configurable set of analog and digital peripherals on a single die. The PIC32MK family belongs to the broader hierarchy: microcontroller -> embedded MCU -> 32-bit MCU -> MIPS-based MCU -> mixed-signal MCU -> semiconductor IC. Combining deterministic real-time control with connectivity peripherals, it is positioned between 8-bit PIC16/PIC24 MCUs and higher-end Cortex-M7 parts in the Microchip portfolio.
Key features include up to 120MHz CPU clock, 1MB ECC-protected Flash, 256KB SRAM, 4KB EEPROM, hardware FPU, four DMA channels, and a 12-bit 3.75MSPS ADC with up to 42 analog inputs. Connectivity includes USB 2.0 Full-Speed On-The-Go, two CAN-FD modules, six UART, four SPI, four I2C, and up to 53 general-purpose I/O pins. The integrated op-amps, comparators and high-resolution PWM (250 ps) target digital power conversion and field-oriented motor control.
The device uses the MIPS32 microAptiv core with a five-stage pipeline, branch prediction and single-cycle MAC, paired with a hardware FPU. ECC on Flash and SRAM increases reliability for industrial-grade deployments. The result is a deterministic real-time MCU capable of closing tight control loops while still running application code, protocol stacks and an embedded web server simultaneously.
Typical applications include field-oriented control (FOC) of BLDC and PMSM motors, multi-axis servo drives, solar inverters, industrial PLCs, building automation gateways, and USB/CAN-connected sensor hubs. The on-chip 12-bit 3.75MSPS ADC and analog comparators simplify mixed-signal front-end designs, while the 250 ps PWM enables high-resolution digital power conversion.
When designing with this device, allocate sufficient decoupling (100 nF + 10 uF near each VDD/VSS pair), follow Microchip's recommended 4-layer PCB stack-up for the 64-TQFP exposed-pad variant, and use MPLAB Harmony 3 code-configurator for peripheral setup. Firmware must initialize the FPU bits in the CP0 register and configure the PLL with an external crystal reference before peripheral bring-up.

Typical Applications
PIC32MK1024GPE064-I/PT is suitable for 6 applications: Field-Oriented Motor Control (BLDC/PMSM), Industrial PLC and Automation Controller, Solar Inverter and Digital Power Conversion, Building Automation Gateway with USB and CAN, Multi-Channel Data Acquisition System, USB HID/CAN Industrial Sensor Hub.
Field-Oriented Motor Control (BLDC/PMSM)
The PIC32MK1024GPE064-I/PT is purpose-built for FOC of brushless DC and permanent-magnet synchronous motors. Its 250 ps high-resolution PWM, hardware FPU and 12-bit 3.75 MSPS ADC with up to 42 channels close current and torque loops within a few microseconds. Six PWM generators with complementary outputs and fault input drive three-phase inverters directly. Compared with software-FPU Cortex-M0 parts, the integrated analog and PWM reduces BOM cost while MPLAB Harmony 3 motor-control libraries accelerate firmware development.

Industrial PLC and Automation Controller
The 120 MHz MIPS32 core with 1 MB Flash and 256 KB SRAM runs IEC 61131-3 logic plus protocol stacks (Modbus, EtherCAT, PROFINET slave) on the PIC32MK1024GPE064-I/PT. Dual CAN-FD, six UART and USB OTG connect to field-bus nodes, HMIs and programming ports. The ECC Flash and -40C to +85C industrial range deliver long-term reliability required for DIN-rail PLCs and remote I/O modules deployed in factories.
Recommended
Solar Inverter and Digital Power Conversion
The PIC32MK1024GPE064-I/PT drives interleaved boost, full-bridge and LLC topologies with its 250 ps PWM resolution, allowing dynamic response below 1% over the 0-100% load step required by grid-tie inverter standards. The 12-bit ADC samples inductor current and PV input voltage synchronously to the PWM carrier, while the FPU executes MPPT and PFC control loops in real time. USB OTG and CAN-FD provide monitoring connectivity to inverter supervisors and home-energy networks.
Recommended
Building Automation Gateway with USB and CAN
With USB 2.0 OTG and dual CAN-FD, the PIC32MK1024GPE064-I/PT bridges BACnet MS-TP, KNX and proprietary HVAC buses to Wi-Fi or Ethernet gateways. The 1 MB Flash fits BACnet stack plus MQTT and TLS client libraries, while 256 KB SRAM buffers sensor telemetry. The industrial -40C to +85C range and ECC Flash survive the temperature swings and brown-out events common in rooftop HVAC units and basement plant rooms.
Recommended
Multi-Channel Data Acquisition System
The 12-bit 3.75 MSPS ADC on the PIC32MK1024GPE064-I/PT supports up to 42 analog inputs, enabling compact multi-channel DAQ systems for vibration, strain-gauge and process monitoring. Four DMA channels stream ADC samples into SRAM without CPU intervention, while the hardware FPU executes FFTs and digital filters in real time. USB OTG streams buffered data to a host PC at up to 12 Mbps full-speed, and CAN-FD timestamps packets for distributed measurement networks.
Recommended
USB HID/CAN Industrial Sensor Hub
The PIC32MK1024GPE064-I/PT integrates USB 2.0 Full-Speed OTG plus dual CAN-FD in a single 64-pin TQFP, allowing compact industrial sensor hubs that expose CAN-FD traffic to a PC over USB. The 120 MHz MIPS32 core handles USB CDC and HID class stacks concurrently with CAN-FD filtering, while 256 KB SRAM buffers CAN message bursts during USB enumeration. This makes the part ideal for bench-top diagnostics and factory-floor sensor gateways.

Design Notes
Place a 100 nF X7R decoupling capacitor within 2 mm of every VDD/VSS pin pair, plus a single bulk 10 uF ceramic at the regulator output. The PIC32MK1024GPE064-I/PT includes an internal LDO; if VIN < 2.5 V ensure the core voltage regulator is configured for full-PLL mode before peripheral bring-up, otherwise the 120 MHz clock will not lock and USB enumeration will fail.
The 64-pin TQFP (10x10 mm) requires a 4-layer PCB stack-up with a continuous ground plane beneath the IC to provide a low-impedance return path for the 120 MHz core and PWM outputs. Route the 12-bit ADC analog inputs away from PWM and clock traces; if analog and digital traces must cross, do so at 90 degrees. The exposed thermal pad (if present in the variant) must be soldered to a 5x5 mm copper pad connected to ground for thermal dissipation.
Estimated: the device consumes approximately 80 mA active at 120 MHz with all peripherals enabled; engineers have reported brown-out resets when 3.3 V LDO headroom falls below 200 mV under USB bus-power inrush. Add a USB VBUS power switch (such as MCP2155) and ensure the 3.3 V rail can source at least 200 mA peak during USB enumeration. Also enable the FPU in CP0 status register before any floating-point library call, otherwise MPLAB XC32 will trap to the default exception handler.
