PIC32MK1024GPD100T-I/PT
PIC32MK1024GPD100T-I/PT - 120MHz 1MB Flash 32-bit MCU | Microchip
The Microchip Technology PIC32MK1024GPD100T-I/PT is a 32-bit MIPS32 microAptiv microcontroller running up to 120 MHz with 1 MB of Flash program memory, 256 KB of SRAM, and 4 KB of EEPROM, housed in a 100-pin TQFP (12x12 mm) package. The 'GPD' suffix denotes the general-purpose dual-motor-control variant with USB Full-Speed, multiple CAN-FD ports, and a rich analog set including up to 42 channels of 12-bit ADC and on-chip operational amplifiers.
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.
