PIC32MZ1024ECH100T-I/PT Overview
What is a PIC32MZ microcontroller? A PIC32MZ is a 32-bit MIPS-based microcontroller from Microchip that sits in the PIC32 family hierarchy: PIC32MX (entry-level, 80 MHz) -> PIC32MZ EC (connectivity, 200 MHz, hardware crypto) -> PIC32MZ EF (graphics/HMI, 252 MHz). PIC32MZ EC devices target industrial connectivity applications requiring Ethernet, CAN, USB, and cryptographic acceleration, filling the role of high-performance industrial microcontrollers within Microchip's broader MCU portfolio alongside dsPIC and SAM devices.
Key features include an integrated 10/100 Ethernet MAC, dual CAN 2.0b controllers, USB 2.0 High-Speed OTG, multiple SPI/I2C/UART interfaces, a 12-bit 500 ksps ADC, and a parallel master port for external memory expansion. The 4-wire SPI with dedicated I/O enables high-throughput communication with external peripherals and serial Flash. The crypto engine accelerates AES, 3DES, SHA, MD5, and RNG operations, offloading these workloads from the CPU. Programmable DMA channels and a 32-channel interrupt controller support deterministic real-time response.
The microAptiv core implements the MIPS32 Release 2 instruction set with DSP ASE, single-cycle multiply-accumulate, and hardware divide, achieving 1.65 DMIPS/MHz. The 5-stage pipeline and dual-set associative prefetch buffer deliver sustained 200 MHz operation with low interrupt latency, making the part suitable for deterministic control and signal processing applications. Memory is arranged with separate bus paths for instruction and data, supporting zero-wait-state Flash execution from cache.
Typical applications include industrial Ethernet gateways, building automation controllers, motor control drives, medical instrumentation with secure connectivity, automotive infotainment sub-systems, IoT edge nodes with TLS acceleration, and graphics HMI panels. The combination of hardware crypto and dual CAN makes it especially suited to industrial networking nodes that require secure cloud connectivity plus fieldbus gateway capability.
Key design consideration: the PIC32MZ1024ECH100 has been superseded by the PIC32MZ1024EFH100 for new designs, which runs at 252 MHz with the same peripheral set. Existing ECH100 designs remain supported but should consider migration. Operating voltage is 2.3V to 3.6V with dedicated analog and digital supply pins that require proper decoupling.

Typical Applications
PIC32MZ1024ECH100T-I/PT is suitable for 6 applications: Industrial Ethernet Gateway, Building Automation Controller, Motor Control Drive, Secure IoT Edge Device, Medical Instrumentation, Automotive Infotainment Sub-system.
Industrial Ethernet Gateway
The PIC32MZ1024ECH100T-I/PT's integrated 10/100 Ethernet MAC, hardware crypto engine, and 1 MB Flash make it ideal for industrial Ethernet gateway designs bridging fieldbus to enterprise networks. The 200 MHz microAptiv core runs TCP/IP stacks plus PROFINET or EtherNet/IP slave protocols with headroom for application logic, while the 512 KB SRAM supports multiple TCP socket buffers without external memory. Hardware AES/SHA acceleration enables TLS 1.2/1.3 for secure cloud connectivity, critical for Industry 4.0 deployments requiring authenticated remote access.
Recommended
Building Automation Controller
Building automation systems require simultaneous support for BACnet/IP, Modbus TCP, CAN, and secure remote management - exactly the multi-protocol capability the PIC32MZ1024ECH100T-I/PT provides. The dual CAN 2.0b controllers support HVAC equipment buses, while the Ethernet MAC uplinks to building management systems with TLS encryption offloaded to the hardware crypto engine. The 1024 KB Flash hosts full BACnet stack with room for custom scheduling logic, and the 160 KB auxiliary Flash stores OTA update images for secure field upgrades without service interruption.
Recommended
Motor Control Drive
Industrial motor drives require deterministic PWM generation, fast ADC sampling for current sensing, and fieldbus connectivity - a combination the PIC32MZ1024ECH100T-I/PT delivers through its 12-bit 500 ksps ADC, programmable DMA, and dual CAN/Ethernet interfaces. The DSP extensions with 64-bit accumulators accelerate field-oriented control (FOC) algorithms, while the 200 MHz core completes current loop calculations in under 5 microseconds. Industrial temperature rating (-40C to +85C) and 3.3V operation match typical drive electronics design requirements.
Recommended
Secure IoT Edge Device
Edge IoT nodes collecting sensor data and uploading to cloud services benefit from the PIC32MZ1024ECH100T-I/PT's hardware crypto engine that accelerates TLS handshakes and AES-GCM data encryption without burdening the application CPU. The 1 MB Flash accommodates TLS libraries plus MQTT/HTTPS client stacks, while 512 KB SRAM buffers sensor data between transmissions. Industrial temperature rating enables deployment in harsh environments, and USB High-Speed OTG supports direct device provisioning and firmware updates during manufacturing.
Recommended
Medical Instrumentation
Medical devices with network connectivity require deterministic performance plus secure data handling - the PIC32MZ1024ECH100T-I/PT's hardware crypto engine, 200 MHz MIPS core, and 1 MB Flash support DICOM/HL7 protocol stacks with TLS-protected transmission of patient data. The 12-bit ADC captures physiological signals at sufficient resolution for many monitoring applications, while DSP extensions enable real-time filtering (IIR/FIR) of ECG, pulse oximetry, or other waveforms. Note: medical safety certification (IEC 60601) is a system-level activity; the MCU alone is not a certified medical component.
Recommended
Automotive Infotainment Sub-system
Automotive infotainment subsystems benefit from the PIC32MZ1024ECH100T-I/PT's dual CAN 2.0b controllers (for CAN-FD-style messaging to head unit and body controllers), USB High-Speed OTG (for smartphone projection, Apple CarPlay, Android Auto bridging), and Ethernet MAC (for high-bandwidth diagnostic links). Note: For under-hood or safety-critical ECUs, AEC-Q100 qualified parts are required; this industrial-grade MCU (-40C to +85C) suits interior cabin electronics and gateway sub-systems but not powertrain or ADAS applications.

Key Differentiators
- Hardware crypto engine on-chip (vs PIC32MZ1024ECG100T-I/PF)
- Higher clock speed with same package (vs PIC32MZ1024EFH100T-I/PT)
- Smaller PCB footprint option (vs PIC32MZ1024ECH100T-I/PF)
Design Notes
The PIC32MZ1024ECH100T-I/PT operates from a single 2.3V to 3.6V supply on the VDD pins, with separate AVDD pins for the analog peripherals (ADC) that should be filtered with a ferrite bead from the digital supply to minimize ADC noise coupling. Place 100 nF decoupling capacitors within 5 mm of every VDD/AVDD pin pair and a 4.7 uF bulk capacitor near the MCU. Per Microchip hardware design checklist, the VCAP pins require external capacitors (typically 4.7 uF each) for the internal core voltage regulator; do not omit these.
Route the 200 MHz CPU clock trace as short as possible with controlled impedance, and place the crystal or oscillator within 5 mm of the OSC1/OSC2 pins with a ground guard ring. For Ethernet designs using an external PHY (e.g., LAN8720A), the RMII traces must be length-matched within 50 mils (1.27 mm) to meet timing. According to Microchip's PCB layout guidelines, the TQFP-100 12x12 mm footprint requires thermal vias under the exposed pad (if present) or, for the standard TQFP, copper pours connected to GND to dissipate the 1-2W typical operating power.
Do not omit the 32.768 kHz secondary oscillator if your application uses the RTCC (Real-Time Clock and Calendar) for timekeeping - the RTCC cannot operate without it. Programming/debug interface requires both the ICSP clock/data pins AND the TRACE pins; pull-ups on TMS for JTAG are recommended. The crypto engine requires proper initialization sequence (CECON register setup) before use; attempting AES operations without enabling the oscillator will hang the CPU. Finally, do not exceed 3.6V on any I/O pin - the part is NOT 5V tolerant.
For USB High-Speed (480 Mbps) operation, the USB D+/D- traces must be 90 ohm differential impedance and length-matched within 150 mils. The USB PHY in the PIC32MZ EC does not integrate the series termination resistors required by the USB specification - external 27 ohm series resistors are needed on D+/D- per the USB 2.0 specification. For Ethernet RMII, the 50 MHz reference clock must be clean (less than 50 ps RMS jitter); use a dedicated oscillator rather than deriving it from the MCU's main PLL.
Compliance Information
Industrial temperature grade (-40C to +85C), not AEC-Q100 qualified. RoHS and REACH compliant per Microchip product declarations. Lead-free and halogen-free per Microchip environmental compliance documentation.
