PIC32MK1024GPK064T-E/MR Overview
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, memory (Flash, SRAM), and programmable peripherals. The PIC32MK family sits within Microchip's MIPS32 portfolio and is designed for real-time control applications where floating-point performance, large memory, and deterministic interrupt handling are required. The microAptiv core supports MicroMIPS mode, which compresses instructions to deliver roughly 40% smaller code density compared to standard MIPS32, allowing engineers to fit more functionality into the 1 MB Flash budget.
Key features include four 64-bit accumulators with a single-cycle MAC for saturating and fractional DSP math, dual-panel Flash with live update for field-firmware swap without downtime, hardware floating-point unit, ECC-protected memory for safety, and a comprehensive analog/digital peripheral set. The device also integrates USB Full Speed, multiple UART/SPI/I2C interfaces, 12-bit ADC modules, and motor-control PWMs.
Architecturally, the PIC32MK combines a high-speed 120 MHz MIPS32 pipeline with DSP extensions (four 64-bit accumulators, single-cycle MAC) and an IEEE 754 floating-point unit, making it suitable for closed-loop control loops and signal processing. The dual-panel Flash subsystem allows one panel to run while the other is being updated, supporting robust firmware-over-the-air (FOTA) upgrades in industrial systems. ECC on Flash and SRAM improves reliability in noisy electrical environments such as motor-drive stages.
Typical applications include brushless DC (BLDC) and permanent-magnet synchronous motor (PMSM) control, industrial automation controllers, multi-channel data acquisition, IIoT edge nodes, and digital power conversion. The 120 MHz core, FPU, and DSP extensions enable real-time field-oriented control (FOC) of three-phase motors without offloading math to a separate DSP. The 12-bit ADCs and high-resolution PWMs are tuned for current-sense sampling and switch-mode power-supply control loops.
When designing with this device, ensure the high-speed oscillator is properly decoupled and that the dual-panel Flash programming model is respected to avoid accidental corruption during live-update operations. For migration between the -E (extended temperature) and -I (industrial temperature) variants, only the operating temperature range differs, so firmware is fully reusable.

Typical Applications
PIC32MK1024GPK064T-E/MR is suitable for 6 applications: Brushless DC Motor Control (FOC), Industrial PLC and Process Controllers, Industrial IoT Edge Nodes, Multi-Channel Data Acquisition Systems, Digital Switch-Mode Power Supplies, Robotics and Multi-Axis Servo Drives.
Brushless DC Motor Control (FOC)
The PIC32MK1024GPK064T-E/MR is purpose-built for Field-Oriented Control (FOC) of three-phase brushless DC and PMSM motors. Its 120 MHz MIPS32 microAptiv core with hardware FPU executes the Clarke/Park transforms and PI control loops in single-precision floating point without software emulation, while four 64-bit accumulators with single-cycle MAC handle the high-rate current-sense math. The integrated 12-bit ADCs simultaneously sample phase currents at the PWM switching frequency, and dedicated high-resolution motor-control PWM modules generate the complementary three-phase gate drive signals with programmable dead time. A 1 MB ECC Flash supports full state-machine and sensor-fusion code with headroom for adaptive control algorithms. For 1 kW-class industrial drives, the device drives the entire FOC loop on-chip, eliminating an external DSP and shrinking the BOM.

Industrial PLC and Process Controllers
In PLC and industrial process controllers, the PIC32MK1024GPK064T-E/MR serves as the central logic solver running IEC 61131-3 style ladder or structured-text control at deterministic 120 MHz cycle times. The 1 MB ECC Flash hosts the full runtime plus application code, while the rich peripheral set (multiple UART, SPI, I2C, CAN-FD capable) interfaces to backplane fieldbuses and remote I/O islands. ECC-protected memory prevents bit-flip-induced erroneous actuator commands in electrically noisy cabinets near VFDs and contactors. The -40C to +125C extended temperature rating supports deployment in unconditioned control panels near motors or outdoor asset cabinets. Hardware FPU accelerates PID and model-predictive control loops, and the dual-panel Flash allows in-service firmware updates without halting the line - a critical capability for continuous-process plants.
Recommended
Industrial IoT Edge Nodes
For IIoT edge nodes, the PIC32MK1024GPK064T-E/MR runs on-device analytics, protocol translation, and secure cloud uplinks from the factory floor. The 120 MHz core plus FPU handles lightweight machine-learning inference and FFT-based vibration analysis on streaming sensor data without offloading to the cloud. USB Full Speed and multiple UART/SPI/I2C ports connect to sensors, while an external MAC/PHY (e.g., LAN8742A) provides Ethernet. ECC Flash prevents firmware corruption in electrically noisy environments, and the dual-panel Flash enables live OTA updates without taking the node offline - critical for deployed assets where reboot is costly. The -40C to +125C rating supports outdoor and cabinet-mounted installations. The MicroMIPS mode reduces code size by ~40%, allowing complex edge analytics to fit in the 1 MB budget.
Recommended
Multi-Channel Data Acquisition Systems
Multi-channel data acquisition systems leverage the PIC32MK1024GPK064T-E/MR's high-performance ADC subsystem and DSP extensions to sample and process multiple analog inputs at high rates. The 12-bit ADC modules support simultaneous sampling, and the FPU-accelerated MIPS32 core runs FFTs and digital filters on incoming streams without dropping samples. Four 64-bit accumulators with single-cycle MAC handle FIR/IIR filter taps at the conversion rate, while 1 MB Flash stores calibration tables and DSP coefficients. The 64-pin QFN package exposes enough I/O to address multiple sensor channels, and the -40C to +125C rating suits test rigs and industrial monitoring equipment. Hardware FPU shortens development time by letting engineers prototype filters in floating point on a PC and port them with minimal scaling.

Digital Switch-Mode Power Supplies
In digital switch-mode power supplies, the PIC32MK1024GPK064T-E/MR replaces traditional analog PWM controllers with a fully programmable digital control loop. Its high-resolution motor-control PWMs (re-purposed for power-supply switching) drive MOSFET gates with nanosecond-resolution duty cycles, while the 12-bit ADCs sample output voltage and inductor current at high frequency for digital peak-current-mode control. The hardware FPU executes the compensator math (Type-II/III) in single precision, enabling adaptive digital compensation that adapts to load transients. ECC Flash stores compensation tables and telemetry. The 120 MHz headroom handles topologies up to ~500 kHz switching frequency with margin, and the -40C to +125C grade supports industrial PSU environments. Live-update dual-panel Flash enables in-field tuning firmware updates without taking the supply offline.
Recommended
Robotics and Multi-Axis Servo Drives
For robotics and multi-axis servo drives, the PIC32MK1024GPK064T-E/MR coordinates joint actuators, IMU fusion, and EtherCAT/CAN-FD fieldbus communication. The 120 MHz core with FPU runs the inverse-kinematics and PID loops for up to 4 axes per device, while the four 64-bit accumulators handle the high-rate feedback math. Dedicated high-resolution PWMs generate the servo drive signals with sub-microsecond resolution, and the 12-bit ADCs sample the encoder/motor current feedback. USB Full Speed and CAN-FD peripherals connect to higher-level motion controllers. ECC Flash is critical in robot cells with EMI from switching motor drives, and the dual-panel Flash enables firmware updates without halting the production line. For higher axis counts, multiple PIC32MK devices can be networked via EtherCAT or CAN-FD in a master-follower topology.

Design Notes
Place decoupling capacitors (100 nF + 1 uF) as close as possible to each Vdd/Vss pin pair. The QFN package exposes a thermal pad (EP) that MUST be soldered to a continuous ground plane with at least 8 thermal vias (0.3 mm drill, 0.6 mm pitch) for heat dissipation. Keep the high-speed oscillator traces short, symmetric, and away from switching power traces. Route analog ADC inputs with a guard ground and keep them perpendicular to switching signals to minimize coupling.
When using the dual-panel live-update Flash feature, follow the boot-sequence and panel-swap procedure documented in the PIC32MK Family Reference Manual. Skipping the panel-swap acknowledgement can leave the device booting the wrong panel after the next reset. Always validate the new firmware image with a CRC check before committing the panel swap. For motor-control applications, ensure the ADC sampling instant is centered within the PWM off-time to avoid switching-noise injection into current-sense measurements.
Estimate: at 120 MHz with all peripherals active, the core current draw is typically ~80 mA from a 3.3 V supply. A bulk 10 uF ceramic + 100 nF decoupling per supply pin is recommended. For USB applications, add a 1 uF bulk capacitor near the Vbus pin and route the USB DP/DM traces as a 90-ohm differential pair with matching length. When migrating from -I (industrial) to -E (extended) grade parts, firmware is identical but verify the temperature sensor calibration in your application code does not assume the -I grade range.
Compliance Information
RoHS compliant per Microchip product page. -E extended temperature grade supports harsh industrial environments but is not AEC-Q100 automotive qualified. For automotive, consider AEC-Q100-qualified PIC32MK variants from Microchip's automotive portfolio.
