PIC32MK1024GPD100T-I/PT Overview
What is a PIC32MK MCU? The PIC32MK family is a high-performance line of 32-bit microcontrollers built on the MIPS32 microAptiv core with an integrated single-precision Floating Point Unit (FPU) and DSP extensions. PIC32MK devices combine general-purpose computation, advanced motor-control peripherals (PWM, QEI, DAC, op-amps), and industrial communication (CAN-FD, USB, I2S) on a single die, targeting motor control, industrial automation, and Industrial IoT (IIoT) applications.
Key features of the PIC32MK1024GPD100T-I/PT include 120 MHz core operation, 1 MB ECC-protected Flash, 256 KB SRAM, 77 user I/O pins, USB 2.0 Full-Speed OTG, four I2C, six I2S, three SPI, four UART, and two CAN-FD interfaces. The analog subsystem provides up to 42 channels of 12-bit ADC with up to 3.75 MSps, four 12-bit DACs, four on-chip op-amps, and three analog comparators, enabling high-performance signal-chain integration without external components.
The architecture pairs the microAptiv core with a 12-channel DMA controller, 8-bit/16-bit parallel master port, and a 16-channel motor-control PWM module with seven independent generators and 16-bit resolution. Hardware cryptographic accelerators are not present on this variant, but the device supports secure firmware update via bootloader and JTAG-based ICSP for in-circuit programming and debugging.
Typical applications include industrial motor drives (BLDC, PMSM, stepper), industrial control PLCs, multi-channel CAN-FD node controllers, USB-connected industrial sensors, building automation gateways, and IIoT edge nodes. The wide operating temperature range (-40C to +85C for the I-grade part) and rich peripheral mix make the part equally at home in factory-floor equipment and commercial IoT devices.
When designing with this device, allocate the 256 KB SRAM carefully across stack, heap, and DMA buffers; 1 MB Flash supports dual-bank live update via the runtime bootloader. The 100-pin TQFP gives access to all 77 I/O pins plus the full analog channel count, so layout decisions should prioritise short analog-trace routing and a solid ground pour under the QFN-style thermal pad area.

Industrial Motor Drive (BLDC / PMSM)
The PIC32MK1024GPD100T-I/PT is purpose-built for multi-axis industrial motor drives, integrating the 120 MHz microAptiv core, 16-channel 16-bit motor-control PWM with seven independent generators, 42 channels of 12-bit ADC up to 3.75 MSps, four on-chip op-amps for current sensing, and four 12-bit DACs for reference generation. The DSP extensions accelerate Clarke/Park transforms and SVPWM routines, while 256 KB SRAM holds field-oriented-control state without external memory. Dual CAN-FD enables integration into multi-node industrial networks and master/slave drive topologies on the same TQFP-100 PCB.
Recommended
Industrial CAN-FD Gateway
The PIC32MK1024GPD100T-I/PT's two independent CAN-FD controllers (ISO 11898-1:2015, 8 Mbps data phase) and USB 2.0 FS OTG make it a natural fit for industrial gateways bridging CAN-FD field buses to USB-connected host PCs or PLCs. The 120 MHz core and 12-channel DMA offload CAN-FD frame handling without CPU intervention, while the 1 MB ECC Flash hosts gateway protocol stacks plus dual-bank firmware update. The 100-pin TQFP gives access to all 77 I/O pins for additional RS-485, RS-232, or Ethernet PHYs in parallel with CAN-FD.
Recommended
USB-Connected Industrial Sensor Hub
The PIC32MK1024GPD100T-I/PT serves as a USB-attached industrial sensor hub thanks to its integrated USB 2.0 Full-Speed OTG controller with on-chip PHY, 42 ADC channels for multi-sensor aggregation, and DSP extensions for on-device signal conditioning. Six I2S and four I2C ports allow direct connection to MEMS microphones, accelerometers, and digital temperature sensors. The 256 KB SRAM buffers multi-rate sensor streams before USB streaming, while 1 MB Flash holds USB class drivers plus sensor-fusion firmware.
Recommended
PLC and Industrial Controller
The PIC32MK1024GPD100T-I/PT powers compact PLCs and industrial controllers where its 120 MHz core handles IEC 61131-3 logic plus ladder/structured-text runtimes, and the 77 I/O pins plus 42 ADC channels aggregate discrete and analog field signals. The 1 MB ECC Flash supports secure boot and runtime firmware update; 256 KB SRAM holds ladder logic state and scan buffers. Dual CAN-FD plus 4 UART and 4 I2C enable Modbus RTU/TCP, EtherNet/IP, and proprietary field-bus stacks in parallel on the same TQFP-100 board.
Recommended
Multi-Channel Data Acquisition System
The PIC32MK1024GPD100T-I/PT excels in multi-channel data acquisition, combining 42 channels of 12-bit ADC at 3.75 MSps aggregate, 12 DMA channels for low-overhead sample streaming, and 256 KB SRAM buffering in real time. The DSP engine runs FFTs and digital filters on-chip before USB or CAN-FD transmission, eliminating the need for an external DSP or FPGA on small-channel-count systems. The 100-pin TQFP provides dedicated analog ground pins that simplify mixed-signal layout for low-noise measurement at the board level.
Recommended
Building Automation Controller
The PIC32MK1024GPD100T-I/PT supports building automation controllers where its USB OTG enables local commissioning via laptop, dual CAN-FD integrates with BACnet/CAN building networks, and the 42-channel ADC aggregates analog sensor inputs (temperature, humidity, CO2, occupancy). The 1 MB Flash stores multi-protocol stacks (BACnet, Modbus, KNX-over-CAN), and the 256 KB SRAM handles HVAC control loops with headroom. The industrial -40C to +85C temperature range suits plant-room and rooftop unit deployment.

Design Notes
The PIC32MK1024GPD100T-I/PT requires a clean 3.3 V supply on VDD with bulk decoupling of at least 10 uF plus 100 nF ceramic bypass per pin pair. VDDCORE has an internal 1.2 V regulator; place a 4.7 uF + 100 nF combination close to the VDDCORE pin. The ADC analog supply (AVDD) should be derived from VDD through a ferrite bead with separate bulk decoupling to avoid digital switching noise coupling into analog measurements, especially when sampling high-impedance sensor sources.
Route the 42 analog ADC inputs as short and symmetric traces away from PWM outputs and switching nodes; use a dedicated analog ground pour connected to the digital ground at a single point near the MCU. Place the 12.000 MHz primary crystal within 5 mm of OSC1/OSC2 with guard traces tied to ground. The 100-pin TQFP has multiple VSS and VDD pins; each pair requires its own decoupling capacitor to meet the 120 MHz core switching transients without VDD droop.
Do not apply 5 V to any I/O pin - the part is 3.3 V logic only and is not 5 V tolerant. For ICSP programming, multiple PGECx/PGEDx pairs are available but must be used as matched pairs (e.g. PGEC2 must pair with PGED2). When configuring the dual-bank Flash for live update, ensure both banks are erased before first boot, otherwise the bootloader may fail to switch banks. Disable unused peripherals via the peripheral module disable (PMD) registers to reduce quiescent current.
Estimated: at 120 MHz operation with all peripherals active, core current draw is typically 50-70 mA, rising to ~90 mA during Flash programming. Power dissipation in the TQFP-100 (theta_JA ~50 C/W on a standard 4-layer JEDEC test board) gives a junction-temperature rise of ~4-5 C above ambient at 70 mA, well within the -40C to +85C operating range. In sealed enclosures without airflow, derate by 10-15 C or add a copper heatsink to the exposed die flag area.
