PIC32MK1024MCM100T-E/PT Visão geral
A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals including ADCs, communication interfaces, timers, and GPIO. Within the broader taxonomy, the PIC32MK belongs to the 32-bit MCU family (32-bit microcontroller -> microcontroller -> embedded processor -> semiconductor). The MIPS32 microAptiv core used here is a Harvard-architecture RISC core with DSP extensions and a hardware Floating Point Unit (FPU) supporting single- and double-precision IEEE 754 math, as well as MicroMIPS compressed mode for up to 40% smaller code footprint.
Key differentiating specifications include four 64-bit accumulators and a single-cycle MAC that supports saturating and fractional math, a 12-bit ADC with up to 42 analog input channels and dual Sample-and-Hold, four on-chip op-amps intended for motor current sensing, plus dedicated Motor Control PWM modules with high-resolution edge placement. Communication peripherals include USB Full-Speed, CAN-FD, and multiple UART/SPI/I2C instances. The 100-TQFP (12x12mm) package exposes the full peripheral set and is pin-compatible with other PIC32MK100-pin family members.
Typical applications span motor control (BLDC, PMSM, ACIM, and stepper drives), industrial control, industrial IoT (IIoT), multi-channel data acquisition systems, and automotive body/comfort modules. The integrated op-amps, HRPWM, and 12-bit ADC deliver a tightly coupled analog front end that removes the need for external signal conditioning in field-oriented control (FOC) loops.
When designing with this part, reserve careful attention to PCB thermal management (theta_JA of the TQFP-100 is package-dependent and limits sustained dissipation) and to ECC initialization of Flash on first programming. The on-chip op-amps have a fixed gain-bandwidth trade-off; for high-bandwidth current sensing an external amplifier may still be preferred.

Aplicações típicas
PIC32MK1024MCM100T-E/PT é adequado para 7 aplicaçãos: Brushless DC (BLDC) Motor Control, Permanent Magnet Synchronous Motor (PMSM) Drives, Industrial Control PLCs and I/O Modules, Industrial IoT (IIoT) Edge Gateways, Multi-Channel Data Acquisition Systems, Automotive Body and Comfort Modules, Solar Inverters and Power Conversion.
Brushless DC (BLDC) Motor Control
The PIC32MK1024MCM100T-E/PT is purpose-built for BLDC motor control. Its 120MHz MIPS32 microAptiv core with FPU executes Field-Oriented Control (FOC) loops with sub-microsecond update rates, while four on-chip op-amps sense phase currents directly without external instrumentation amplifiers. The 12-bit ADC with up to 42 channels and dual sample-and-hold enables simultaneous current and voltage sampling at the PWM reload edge, eliminating switching-noise-induced aliasing. Compared with a Cortex-M4 alternative at the same price, the integrated op-amps and HRPWM reduce BOM cost by $1-2 and shrink PCB area by ~30%.
Recomendado
Permanent Magnet Synchronous Motor (PMSM) Drives
PMSM servo drives benefit from the PIC32MK1024MCM100T-E/PT's high-resolution Motor Control PWM (HRPWM) with edge placement resolution down to 250ps, allowing precise current shaping at 20kHz switching frequency. The 1MB Flash accommodates full state-space observers and sensorless FOC algorithms in MicroMIPS compressed mode (up to 40% smaller code). The ECC-protected Flash and dual-panel live update meet IEC 60730 Class B safety requirements for industrial drives. The -40C to +125C E-temp grade supports under-hood mounting near motor housings.
Recomendado
Industrial Control PLCs and I/O Modules
The CAN-FD peripheral on the PIC32MK1024MCM100T-E/PT enables high-bandwidth industrial networking with payload lengths up to 64 bytes at 5Mbps, ideal for distributed I/O backplanes and remote sensor nodes. The 100-pin TQFP exposes 78 GPIO through PPS, sufficient for multi-channel industrial controllers. The 12-bit ADC with 42 input channels handles up to 42 analog sensors without an external multiplexer. Integrated USB Full-Speed simplifies commissioning and firmware update via standard USB host ports in factory-floor equipment.
Recomendado
Industrial IoT (IIoT) Edge Gateways
The PIC32MK1024MCM100T-E/PT serves as a low-power edge node for IIoT gateways, with CAN-FD for industrial bus access and USB Full-Speed for diagnostics. The 256KB SRAM supports buffering of MQTT/TLS stacks (with optional CryptoAuth secure element), while the 1MB Flash stores firmware images for OTA updates via dual-panel live update. Compared to ESP32-class IIoT modules, this MCU offers deterministic real-time response under 1us and superior EMC tolerance for factory-floor deployment at 125C ambient.
Recomendado
Multi-Channel Data Acquisition Systems
For high-channel-count data acquisition (DAQ) systems, the PIC32MK1024MCM100T-E/PT provides up to 42 channels of 12-bit ADC input with dual sample-and-hold, allowing simultaneous sampling of paired signals (such as voltage and current) at up to 3.75 MSPS aggregate. The 256KB SRAM buffers multi-channel waveform captures before USB streaming. Internal op-amps can buffer low-impedance sensors directly. The 120MHz MIPS core runs on-the-fly FFT and decimation for vibration and power-quality analysis.
Recomendado
Automotive Body and Comfort Modules
The PIC32MK1024MCM100T-E/PT -40C to +125C "E" temperature grade and integrated CAN-FD support automotive body modules such as HVAC controllers, seat controllers, and mirror adjusters. The Motor Control PWM and op-amps handle small brushed DC and stepper motors used in HVAC flaps and headlamp leveling. The 1MB ECC Flash supports AUTOSAR-style layered firmware. Confirm AEC-Q100 qualification status with Microchip for automotive OEM programs; the same die is available with full automotive grade via specific part number suffixes.
Recomendado
Solar Inverters and Power Conversion
The PIC32MK1024MCM100T-E/PT's DSP extensions (4x 64-bit accumulators, single-cycle MAC) accelerate digital control loops for solar MPPT and grid-tie inverter firmware. The HRPWM generates switching waveforms at 250ps resolution, supporting MHz-class power-converter switching frequencies. The 12-bit ADC samples multiple phase currents and DC bus voltages synchronously. The 1MB Flash holds complex grid-synchronization code including anti-islanding routines.

Notas de projeto
The PIC32MK1024MCM100T-E/PT operates from 2.2V to 3.6V. Place a 10uF bulk decoupling capacitor at each VDD/VSS pair (the device has four VDD/VSS pairs on the TQFP-100 footprint at pins 11/12, 31/32, 49/50, 67/68, 91/92). Add 100nF ceramic bypass caps within 2mm of every VDD pin. Analog AVDD should be derived from VDD through a ferrite bead and decoupled with 100nF + 10uF; share a single ground via stitch array at the IC's exposed pad region (TQFP-100 has no thermal pad - ensure solid ground plane coverage directly under the package).
The 100-pin TQFP-100 package has a thermal resistance (theta_JA) of approximately 35-45 C/W depending on PCB copper area and airflow. At 120MHz full CPU load with all peripherals active, the core current draw can reach 60mA at 3.3V (~200mW dissipation). For industrial applications at 85C+ ambient, design a copper pour covering at least 25x25mm around the package and add 4-6 thermal vias to an internal ground plane. Avoid placing the IC near heat sources (LDOs, MOSFETs).
Common pitfalls when designing with the PIC32MK1024MCM100T-E/PT: (1) Forgetting to configure PPS (Peripheral Pin Select) for each peripheral function - unlike legacy PIC32, most peripherals require explicit pin mapping via PPS registers; (2) not initializing the ECC Flash correctly on first programming - ECC must be enabled in the FDEVOPT register before user code execution; (3) over-driving the ADC - input signals above VDD+0.3V can permanently damage analog inputs, so add external clamping diodes for >3.6V signals; (4) confusing the on-chip op-amps (used for current sensing) with general op-amps - the internal op-amps have specific pin assignments (OPA1IN+, OPA1IN-, OPA1OUT) and fixed gain/bandwidth trade-offs.
For high-speed SPI (>40MHz) and USB Full-Speed signals, route traces over a continuous ground plane with 50 ohm characteristic impedance controlled by trace geometry. Keep crystal traces (primary oscillator and 32.768kHz) within 5mm of the IC pins and shield with ground guard traces to prevent coupling to nearby analog inputs. The CAN-FD bus signals should be routed as a differential pair with 120 ohm impedance, and twisted-pair cable external to the PCB must be terminated with 120 ohms at each end per ISO 11898.
Informações de conformidade
RoHS and REACH compliant per Newark product page (82AH3663) and DigiKey listings. "E" temperature grade (-40C to +125C) supports industrial and automotive-grade deployments, but AEC-Q100 status should be confirmed directly with Microchip for the specific automotive part number.
