PIC32MK1024GPK064-I/PT Overview
A 32-bit microcontroller (MCU) is a system-on-chip containing a processor core, program and data memory, and a configurable set of peripherals such as timers, ADCs, communication controllers, and GPIO. Within the broader taxonomy, this part belongs to the PIC32 family of MIPS-based MCUs, itself a sub-family of Microchip's PIC microcontroller line, which sits within the Embedded > Microcontrollers segment of integrated circuits. The PIC32MK GPK series specifically targets general-purpose and motor-control designs that previously required a DSP.
Key features of the PIC32MK1024GPK064 include a single-precision Floating-Point Unit (FPU), MicroMIPS mode for 40% smaller code size, four 64-bit accumulators, a single-cycle MAC for saturating and fractional math, 5V-tolerant I/O with up to 22 mA source/sink, and selectable internal pull-ups, pull-downs, and open-drain modes. The device integrates multiple high-speed analog peripherals including 12-bit ADCs with up to 3.5 Msps sampling, high-speed analog comparators, and DAC outputs, all tuned for closed-loop PWM motor control.
Communication interfaces include dual USB FS OTG, CAN FD (in the MCJ variant - note GPK has no CAN-FD per Future Electronics), multiple UART/SPI/I2C, and a Parallel Master Port. Memory options include 1 MB Dual-Panel Flash with Live Update support and 4 KB EEPROM emulation. A cryptographic engine and true random number generator (TRNG) are integrated for secure IIoT deployments.
Typical applications include BLDC and PMSM motor drives (FOC), industrial PLCs, multi-channel sensor acquisition systems, solar inverter controllers, and IIoT edge nodes. The TQFP-64 footprint and -40C to +85C industrial temperature grade (-I suffix) make it a drop-in upgrade path for designs migrating from PIC32MX parts.
When designing with this device, place the dual USB bus capacitors within 5 mm of the VUSB pins, and observe the VDD/VSS pairing requirement of one bulk cap per pin pair. Use Microchip's Harmony configurator to map peripherals to specific PPS pins and avoid pin conflicts on this 64-pin TQFP layout.

Design Notes
The PIC32MK1024GPK064 requires multiple power rails: VDD (2.3V-3.6V core supply), VDDIO (I/O supply, must equal VDD), AVDD (analog ADC supply, must equal VDD with ferrite isolation recommended), and VUSB (3.3V USB transceiver supply). Place one 100 nF decoupling capacitor within 2 mm of every VDD/AVDD pin pair. Add a 4.7 uF bulk capacitor near the package's VDD corner. Power-rail sequencing is not required, but the USB VBUS sense pin must be held low when VDD is below 2.9V to prevent back-powering. Per the Microchip PIC32MK datasheet (DS60001570D), an external reset supervisor is recommended for industrial applications where the internal POR may not handle fast power-cycles.
At 120 MHz with all peripherals active and dual USB transmitting, the PIC32MK1024GPK064-I/PT in the TQFP-64 (10x10 mm) package typically dissipates 240-300 mW - within the package's 1 W thermal budget without special PCB treatment. Estimated: theta_JA for TQFP-64 on a 2-layer 1-oz copper JEDEC EIA/JESD51 test board is approximately 55 C/W. For industrial-temperature (85C ambient) designs, target a junction-to-ambient rise below 20 C by providing at least 4-layer PCB with a 25x25 mm copper flood on the top layer. The exposed thermal pad on TQFP-64 packages improves heat conduction if soldered to a copper pour.
Use Microchip's Harmony 3 Configurator tool to assign peripherals to specific PPS (Peripheral Pin Select) pins before PCB layout - the PIC32MK1024GPK064 remaps nearly all digital peripherals to any I/O pin, but PPS inputs have a maximum of 8 unique mapping sources per pin group. Place the 32.768 kHz low-power crystal or external oscillator within 5 mm of the SOSC pins with a guarded ground ring. For USB, route the D+/D- differential pair as 90 ohm impedance-matched traces of equal length, within 5 mm of the VUSB capacitor. The analog ADC inputs should be isolated from digital switching signals with a ground moat - place AVDD ferrite between AVDD and VDD to suppress digital switching noise from coupling into ADC conversions.
Do not assume the PIC32MK1024GPK064-I/PT has CAN-FD - this is the GPK variant with 2x USB only. For CAN-FD, choose PIC32MK1024MCJ064 or PIC32MK1024GPD064. Also, the PPS pin mapping must be programmed BEFORE the peripheral is enabled or the default fixed-pin assignment is lost - check the configuration bits in MPLAB X. Finally, the dual-panel Flash Live Update feature requires firmware to explicitly call the panel-swap sequence; simply writing to the inactive panel is not sufficient for OTA updates.
The PIC32MK1024GPK064's 12-bit ADC achieves best performance when the analog source impedance is below 1 kohm - use external op-amp buffers (e.g., MCP6002) on high-impedance sensors. For multi-channel sequential sampling, account for the input charge-sharing settling time: at full 3.5 Msps, allow at least 200 ns between channel switches. The high-speed PWM outputs should drive gate drivers through 33 ohm series resistors to dampen transmission-line reflections, especially when traces exceed 25 mm in length.
Compliance Information
RoHS compliant per Microchip product page. The -I/PT industrial grade is not AEC-Q100 qualified - use automotive-qualified PIC32MK Q1 variants for AEC-Q100 applications. Microchip publishes a separate Conflict Minerals Report (CMRT) covering this part.
