PIC32MK1024GPD064T-I/MR 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O into one package. The PIC32MK family belongs to the broader PIC32 family, which uses the MIPS32 microAptiv core architecture; the GPD sub-family is a dual-partition variant with separate Flash and SRAM regions optimized for deterministic real-time control. Within Microchip's portfolio, PIC32MK MCUs sit between the lower-pin-count PIC32MX and the higher-performance dsPIC33CH dual-core DSP controllers.
Key features include 120 MHz core speed with DSP instructions and FPU, 1 MB dual-bank Flash, 256 KB SRAM, four independent analog comparators with 32 ns response, multiple 12-bit ADCs up to 3.5 MSPS, three 4-channel high-speed PWM modules (250 ps resolution), six UART, three SPI, four I2C, USB-FS, and CAN-FD. The device also integrates a Cryptographic Engine, a Random Number Generator, and an RTCC.
Technically, the PIC32MK1024GPD064T-I/MR uses a Harvard architecture with separate instruction and data paths, dual partition Flash for live update, and a 32-channel DMA controller. The 12-bit ADC includes oversampling and a shared 1.5 MSPS SAR core; the motor-control PWM (MCPWM) supports up to 12 outputs with 250 ps edge resolution. Operating voltage is 2.3V to 3.6V, with a -40C to +85C industrial temperature range, and the chip is supplied in tape-and-reel.
Typical applications include digital power conversion (DC-DC, PFC, inverters), field-oriented motor control (BLDC, PMSM), industrial PLC modules, and functional safety designs. The part is recommended for new motor-control and digital-power designs by Microchip.
When designing with the PIC32MK1024GPD064T-I/MR, ensure adequate decoupling on AVDD rails (4.7 uF plus 0.1 uF ceramic) and route the analog ground plane to minimize ADC noise coupling. The 9x9 mm QFN has a thermal pad that must be soldered to a continuous ground plane for heat dissipation, especially at full 120 MHz with all peripherals active.

設計ノート
The PIC32MK1024GPD064T-I/MR requires separate AVDD/AVSS analog supplies for the 12-bit ADC; place a 4.7 uF tantalum plus 0.1 uF ceramic decoupling pair within 5 mm of the AVDD pins. The internal 1.2V core regulator needs a 1 uF ceramic on the VCAP pin. Inrush current at startup can exceed 80 mA on the 3.3V rail; ensure upstream DC-DC has sufficient bulk capacitance (>= 47 uF) for clean rise. Brown-out reset (BOR) must be enabled to prevent code execution at low voltage.
Estimated: at maximum 120 MHz with all peripherals active, the 64-QFN package dissipates approximately 0.45W, yielding a junction temperature rise of about 30C above ambient (theta_JA = 65 C/W on a 4-layer PCB). For designs operating above 70C ambient, solder the exposed thermal pad to a continuous ground pour of at least 1 square inch. Avoid placing the MCU directly above high-current switching components; thermal coupling from MOSFETs can push the junction above 105C during FOC operation.
The 64-QFN 9x9 mm package has a 0.5 mm pitch and exposed thermal pad requiring precise PCB layout. Use NSMD pads with a 1:1 pad-to-pitch ratio and 0.3 mm via-in-pad thermal array (8-12 vias, 0.3 mm drill) under the EP for thermal dissipation. Route analog signals (ADC inputs) on the top layer with ground guard traces, and keep PWM traces away from analog inputs by at least 3 mm to prevent switching noise coupling into ADC samples.
Do not attempt live firmware updates on a single-bank Flash configuration - the PIC32MK1024GPD064T-I/MR's dual-bank feature must be enabled in the FBOOT configuration bits, otherwise the MCU will fail to boot after a bad update. The MCPWM module requires specific unlock sequence before accessing protected PWM control registers; failure to unlock causes silent PWM output disable. USB-FS requires a 48 MHz clock from the Primary Oscillator with PLL; crystal accuracy must be within 50 ppm for USB compliance.
