PIC32MK1024MCM100-E/PT Descripción general
A 32-bit microcontroller (MCU) is a single-chip computing system integrating a CPU core, volatile memory (SRAM), non-volatile memory (Flash/EEPROM), and a rich set of peripherals (ADC, PWM, communication interfaces). The PIC32MK family sits at the high-performance tier of Microchip's PIC32 portfolio, bridging the gap between traditional 8/16-bit MCUs and higher-cost application processors. The MIPS32 microAptiv core executes instructions in a single cycle for most operations, supports MicroMIPS mode for up to 40% smaller code, and includes four 64-bit accumulators plus a single-cycle MAC for saturating and fractional arithmetic.
Key features include four 12-bit ADC modules with up to 6 Msps combined sampling rate, dedicated Motor Control PWM (MCPWM) with 12 channels, two USB 2.0 Full-Speed ports, two CAN-FD controllers, six UART, four SPI, and four I2C interfaces. Operating voltage spans 2.3 V to 3.6 V across an industrial temperature range of -40 C to +125 C. The dual-panel Flash architecture supports Live Update, allowing firmware upgrades without service interruption.
Typical applications span industrial motor drives (BLDC, PMSM, AC induction), factory automation PLCs, IIoT edge nodes, power-conversion control loops, and multi-axis robotic control. The integrated FPU and DSP MAC eliminate external math accelerators, simplifying PCB layout and reducing BOM cost for control algorithms that require trigonometric or matrix operations in real time.
When designing with this device, reserve at least 25% Flash for OTA updates if Live Update is planned, and ensure the 12-bit ADC reference voltage decoupling follows the manufacturer reference schematic to avoid gain error in motor current sensing. The 100-pin TQFP footprint is shared across the PIC32MK MCM/GPK/MCF family, simplifying PCB reuse across variants.

Aplicaciones típicas
PIC32MK1024MCM100-E/PT es adecuado para 6 aplicacións: BLDC / PMSM Motor Control Drives, Industrial PLC and Factory Automation, Industrial IoT (IIoT) Edge Gateways, Power Conversion and Digital PFC Control, Multi-Axis Robotic Control, Solar Inverter and Energy Management.
BLDC / PMSM Motor Control Drives
The PIC32MK1024MCM100-E/PT's 12 dedicated Motor Control PWM channels with complementary outputs and dead-time insertion make it the canonical choice for three-phase BLDC and PMSM drives. Four 12-bit ADCs sample motor phase currents and back-EMF at up to 6 Msps combined, enabling Field-Oriented Control (FOC) loops at PWM frequencies up to 20 kHz. The integrated single/double-precision FPU executes Park/Clarke transforms and PI controllers in hardware-speed math without offloading to a coprocessor, while the 120 MHz MIPS32 core leaves headroom for CANopen or EtherCAT slave stacks.
Recomendado
Industrial PLC and Factory Automation
The 256 KB SRAM and 1 MB ECC Flash accommodate IEC 61131-3 runtime environments, ladder logic interpreters, and Modbus/TCP or PROFINET stacks with margin. Six UART, four SPI, and four I2C interfaces allow direct connection to PLC expansion I/O modules, while two CAN-FD controllers handle real-time fieldbus communication on the factory floor. The industrial -40 C to +125 C temperature grade and ECC-protected Flash ensure reliable operation in 24 V cabinet environments with electrical noise and temperature swings.
Recomendado
Industrial IoT (IIoT) Edge Gateways
With dual USB 2.0 Full-Speed ports for Wi-Fi/BLE modules, two CAN-FD controllers for fieldbus, and a 120 MHz FPU-enabled core, the PIC32MK1024MCM100-E/PT acts as an IIoT edge node running TLS/DTLS and MQTT-SN while simultaneously controlling actuators. The 1 MB Flash is sufficient for secure-boot loaders and OTA staging areas, and the dual-panel Live Update architecture makes firmware updates non-disruptive to the industrial process. Industrial temperature rating and ECC Flash satisfy IEC 62443 reliability expectations for unattended field cabinets.
Recomendado
Power Conversion and Digital PFC Control
The PIC32MK1024MCM100-E/PT's 120 MHz FPU math, four 12-bit ADCs, and MCPWM make it suitable for digital PFC, interleaved LLC, and full-bridge phase-shift converters. ADC sampling rates up to 6 Msps catch the zero-crossing of high-frequency switching nodes without aliasing, and the 12 MCPWM channels can drive up to six interleaved boost phases. ECC-protected Flash prevents silent firmware corruption in unattended rectifiers, where field service is expensive.
Recomendado
Multi-Axis Robotic Control
Six UART, four SPI, and the FPU make the PIC32MK1024MCM100-E/PT a controller for multi-axis robotic arms running inverse-kinematics and trajectory interpolation in real time. Each axis needs six MCPWM channels for a 3-phase BLDC plus an encoder interface; the chip can drive two full three-phase axes simultaneously with adequate compute headroom for CAN-FD-based distributed-robot coordination. ECC Flash and the -40 C to +125 C industrial temperature grade support outdoor and harsh-warehouse deployments.
Recomendado
Solar Inverter and Energy Management
In solar inverters and energy-storage systems, the PIC32MK1024MCM100-E/PT handles MPPT algorithms, grid-synchronization PLL math, and isolated commutation with its FPU and DSP MAC. The dual-panel ECC Flash allows OTA firmware upgrades under regulatory supervision without taking the inverter offline. Two CAN-FD ports connect to battery management and grid-meter subsystems, while four 12-bit ADCs digitize current, voltage, and temperature at the conversion stage.

Notas de diseño
Decouple each VDD/AVDD pin pair with a 0.1 uF X7R ceramic plus a single 10 uF bulk tantalum or ceramic near the package. The PIC32MK integrates four ADCs with independent AVdd references; each AVDD pin pair should have its own 10 nH inductor + 10 uF cap to isolate the analog supply from digital switching noise. Failing to separate digital and analog ground returns will cause current-sense ADC readings to drift during PWM transitions.
Estimated: The 100-pin TQFP package has a typical theta_JA of around 40 C/W on a 4-layer JEDEC test board. For continuous operation near maximum CPU load at 120 MHz with peripheral DMA active, ensure the PCB layout allocates a copper pour of at least 2 square inches under the exposed die-pad-adjacent area to keep junction temperature rise below 30 C. For full -40 C to +125 C operation, validate with a thermal-capture profiling run before locking the BOM.
Route the 12 MCPWM outputs as matched-length differential pairs if driving long gate-drive cables, otherwise use 8-15 mil 50-ohm traces with a continuous ground reference plane. Keep ADC traces away from PWM switching nodes; place a digital ground guard ring around each current-sense input. The two USB FS ports require 90-ohm differential routing on D+/D-; max recommended length is 50 mm on FR4.
Do not assume the dual-panel Flash Live Update feature works out of the box: the linker script must place an ISR vector stub in both panels, and the bootloader must be programmed in a region protected from accidental erasure. Forgetting to set the FSLEEP/RETEN retention bits causes SRAM loss during deep sleep. Also, the CAN-FD controllers require a clean 40 MHz clock source; an inaccurate crystal will fail ISO 11898-1 conformance tests.
