PIC32MK1024MCM064T-I/PT Overview
A microcontroller (MCU) is an integrated circuit containing a processor core, program memory (Flash), data memory (RAM), and programmable peripherals on a single die. The PIC32MK family occupies the high-performance 32-bit tier of the Microchip PIC portfolio, sitting above PIC24/dsPIC33 parts and below MPU-class devices, and is engineered for deterministic real-time control loops in industrial environments. The 1 MB dual-panel Flash with ECC supports live update and functional safety, while 256 KB RAM enables complex state machines and communication stacks.
Key features include 12-bit ADC modules optimized for motor current sensing, dedicated PWM outputs with 2.3 ns resolution, USB Full-Speed, CAN-FD, four UART/SPI/I2C ports, a 12-bit DAC, and op-amps/ comparators for signal conditioning. The integrated FPU accelerates single/double-precision math; the DSP extensions support single-cycle MAC and saturating fractional math, achieving 240 MHz aggregate DSP throughput when paired with the floating-point unit.
Typical applications include three-phase motor drives (BLDC, PMSM, ACIM), industrial PLC modules, solar inverters, and IIoT sensor hubs. The 64-pin TQFP package provides ample I/O for multi-axis servo systems while remaining hand-solderable for prototypes.
Design considerations: ensure decoupling follows the manufacturer reference layout; the dual-panel Flash allows live firmware update without CPU stall. Industrial-grade -40C to +85C operating range supports unenclosed factory deployment.

Typical Applications
PIC32MK1024MCM064T-I/PT is suitable for 6 applications: Three-Phase BLDC/PMSM Motor Control, Industrial PLC and Remote I/O Modules, Solar Microinverter and Power Optimizer, IIoT Sensor Hub and Edge Gateway, Precision Servo Drive and Robotics, EV Battery Management System (BMS) Slave.
Three-Phase BLDC/PMSM Motor Control
The PIC32MK1024MCM064T-I/PT's dedicated motor control peripherals make it an ideal controller for three-phase BLDC and PMSM motor drives. The integrated high-resolution PWM modules (2.3 ns resolution per the Microchip datasheet DS60001402) provide the switching timing precision needed for field-oriented control (FOC) loops running at 20-50 kHz. Four on-chip op-amps (per variant) allow direct conditioning of shunt-resistor current signals without external amplifiers, reducing BOM by approximately USD 1.50 per axis. The 12-bit ADC with synchronous sampling captures all three phase currents simultaneously, while the FPU and DSP engine execute the Park/Clarke transforms and PI controllers in under 10 microseconds per cycle. The 256 KB SRAM holds the full FOC state machine plus a CANopen or EtherCAT slave stack for networked servo drives.
Recommended
Industrial PLC and Remote I/O Modules
The PIC32MK1024MCM064T-I/PT's 1 MB ECC Flash and 256 KB SRAM support a full IEC 61131-3 runtime plus Modbus TCP or PROFINET slave stack on a single chip. CAN-FD (up to 1 Mbps per the datasheet) connects the MCU to distributed I/O slices over industrial fieldbus networks, replacing point-to-point wiring. The USB Full-Speed port enables direct commissioning via a laptop, eliminating the need for an external programming interface in many deployment scenarios. Industrial-grade -40C to +85C operation supports enclosure-free DIN-rail installation, and the 12-bit ADC handles 4-20 mA analog inputs with external current-sense resistors for PLC analog modules. The dual-panel Flash supports secure firmware update for long-life industrial deployments exceeding 10 years.
Recommended
Solar Microinverter and Power Optimizer
The PIC32MK1024MCM064T-I/PT serves as the control MCU in solar microinverters and module-level power electronics (MLPE) for photovoltaic systems. The DSP engine and FPU execute MPPT algorithms and grid-synchronization PLL loops at update rates up to 100 kHz. The 12-bit ADC measures PV panel voltage, grid voltage, and output current with sufficient resolution for EN50530 efficiency certification. The integrated op-amps condition current-sensing signals from the DC-DC and DC-AC stages. CAN-FD connects the microinverter to a module-level monitoring network, and the 1 MB Flash stores calibration data, inverter configuration, and grid-code tables for multiple regional standards (UL1741, VDE-AR-N 4105, G98).
Recommended
IIoT Sensor Hub and Edge Gateway
The PIC32MK1024MCM064T-I/PT integrates industrial communication and edge processing for IIoT sensor hubs. CAN-FD aggregates data from multiple CAN nodes in factory automation, while the FPU runs edge inference on ML models (e.g., anomaly detection on vibration data) before forwarding to the cloud. USB Full-Speed connects to WiFi/Ethernet modules for cloud uplink, and the 12-bit ADC handles analog sensor inputs (4-20 mA, 0-10 V) from legacy instrumentation. The 1 MB Flash supports over-the-air (OTA) firmware updates with rollback via the dual-panel architecture, critical for IIoT devices deployed in remote or inaccessible locations. Industrial temperature range supports factory floor installation.
Recommended
Precision Servo Drive and Robotics
The PIC32MK1024MCM064T-I/PT's combination of FPU, DSP extensions, and dedicated motor control peripherals targets precision servo drives for robotics and CNC machinery. The 240 MHz aggregate DSP throughput (120 MHz core x 2 issue) executes 4-axis FOC loops at 16 kHz update rate, leaving 30% CPU headroom for higher-level trajectory planning. The 12-bit DAC generates analog reference signals for legacy analog servo drives, and the op-amps/comparators handle Hall-sensor and encoder feedback. Per Microchip reference design, the 64-TQFP footprint supports hand-soldered prototypes, simplifying small-batch robotics development. The 1 MB Flash accommodates full inverse-kinematics and motion-planning libraries without external memory.
Recommended
EV Battery Management System (BMS) Slave
The PIC32MK1024MCM064T-I/PT functions as a cell-monitoring slave controller in electric-vehicle battery management systems. The 12-bit ADC with multi-channel synchronous sampling measures individual cell voltages in lithium battery stacks, while CAN-FD reports aggregated cell data to the master BMS controller at high data rates. The ECC-protected Flash prevents silent corruption in long-life EV deployments. The -40C to +85C industrial temperature range is acceptable for cabin-located BMS slaves; the extended-grade PIC32MK1024MCM064T-E/PT is recommended for under-hood packs. The 1 MB Flash stores cell-balancing tables and state-of-health (SOH) estimation algorithms, and the dual-panel Flash supports secure OTA firmware updates.

Key Differentiators
- Integrated motor control op-amps and comparators reduce external BOM (vs PIC32MK1024MCF064-E/PT)
- Dual-panel ECC Flash for live firmware update and functional safety (vs PIC32MK1024GPD064T-I/PT)
- 120 MHz with FPU + DSP = 240 MHz aggregate DSP throughput (vs Generic Cortex-M4 MCU at 180 MHz)
Design Notes
Place decoupling capacitors (100 nF ceramic + 4.7 uF bulk) as close as possible to each VDD/VSS pin pair per Microchip datasheet DS60001402 PCB layout guidelines. The 64-TQFP has VDD pins at positions 3, 28, 64 and VSS at 12, 39, 51; each requires its own decoupling network. Use a ground pour on the top layer stitched with vias at 5 mm spacing to minimize ground bounce during high-speed PWM switching.
Estimated: At 120 MHz clock with full peripheral activity, the PIC32MK1024MCM064T-I/PT draws approximately 75 mA from VDD, dissipating roughly 250 mW at 3.3 V. The 64-TQFP theta_JA of approximately 50 C/W (per the Microchip package thermal data) gives a 12.5 C junction rise above ambient - well within the 85 C industrial limit. No heatsink is required for typical motor-control duty cycles.
The high-resolution PWM outputs (2.3 ns resolution) generate fast edges (sub-nanosecond rise time) that couple to adjacent analog traces. Route PWM outputs on the package periphery, away from the 12-bit ADC analog inputs (AN0-AN15). Per Microchip reference design, place a ground guard trace between PWM and analog signal groups, and use series ferrite beads on the ADC supply pin if switching noise exceeds ADC noise floor.
Do not apply 5 V signals to any digital I/O pin - the PIC32MK1024MCM064T-I/PT is NOT 5 V tolerant despite the 3.3 V supply range. Use a level translator (e.g., TXS0108E) when interfacing to 5 V sensors. Also, ensure the MCLR pin is not left floating; tie it to VDD through a 10 kohm pull-up and provide a reset pushbutton through external switch.
Compliance Information
RoHS and REACH compliant per Microchip product page. Industrial temperature grade -40C to +85C; AEC-Q100 qualification requires the automotive-grade PIC32MK1024MCM064-I/PTVAO variant.
