PIC32MZ1024ECH100-I/PT Overview
A 32-bit PIC microcontroller is a member of the microcontroller (MCU) family of integrated circuits - small, self-contained computing systems that combine a CPU core, program and data memory, and a rich set of on-chip peripherals (timers, communication controllers, ADCs, GPIO) on a single die. The PIC32MZ family is Microchip's high-performance branch of the PIC32 portfolio (32-bit MIPS), positioned above the PIC32MX series and below the SAME70/SAMV71 (Cortex-M7) class in compute throughput. The ECH sub-family adds a dedicated Ethernet MAC and a hardware Crypto Accelerator to the baseline PIC32MZ EF feature set.
Key features include a 200 MHz core clock with hardware multiply/divide and DSP extensions, dual 12-bit ADC modules, multiple UART/SPI/I2C/CAN interfaces, an integrated 10/100 Ethernet MAC, a hardware Crypto Accelerator for AES/SHA/TDES, and an Enhanced Parallel Master Port (EPM) for external memory. The 100-pin TQFP package exposes up to 78 user I/O lines. An integrated FPU is not present on the ECH sub-family; floating-point is handled in software unless an FPU-equipped PIC32MZ EF or PIC32MZS variant is selected.
Typical applications include industrial Ethernet nodes (PROFINET, EtherCAT slave, Modbus TCP), secure IoT gateways, graphical HMI controllers, building automation bridges (BACnet, KNX/IP), motor control with CAN, and USB- or Ethernet-connected medical instrumentation. The Crypto Accelerator offloads TLS handshake steps, while the Ethernet MAC combined with the large SRAM enables on-chip TCP/IP stacks without an external PHY controller.
When designing with this device, allocate decoupling as one 100 nF ceramic per VDD/VDDIO pin pair plus a single 4.7 uF bulk near the regulator. The Ethernet MAC requires an external 50 MHz oscillator or 25 MHz crystal plus magnetics; leave room for a PHY footprint. Trace the trace impedance-controlled RMII/RGMII pair to 50 ohms on at least the top layer.

Typical Applications
PIC32MZ1024ECH100-I/PT is suitable for 6 applications: Industrial Ethernet Gateway, Secure IoT Gateway with TLS, Building Automation Controller (BACnet, KNX/IP), Industrial HMI / Touch Controller, Connected Medical Instrumentation, Motor Control with CAN (Industrial Drives).
Industrial Ethernet Gateway
The PIC32MZ1024ECH100-I/PT is purpose-built for industrial Ethernet nodes such as PROFINET, EtherCAT slave, Modbus TCP, and EtherNet/IP bridges. Its integrated 10/100 Ethernet MAC eliminates the need for an external MAC controller, while the 512 KB SRAM comfortably hosts an embedded TCP/IP stack plus a real-time application layer within the 1 MB Flash budget. The 200 MHz MIPS32 microAptiv core delivers sufficient throughput to handle a full TLS handshake with negligible CPU loading, even when the Hardware Crypto Accelerator offloads AES/SHA/TDES primitives. Typical placement: one PHY (e.g., KSZ8061) connected via RMII to the MAC, with the MCU running an MPLAB Harmony Net stack at line-rate.
Recommended
Secure IoT Gateway with TLS
The PIC32MZ1024ECH100-I/PT targets secure connected devices that need hardware-rooted TLS. The integrated Crypto Accelerator performs AES-128/256, SHA-256, and TDES in hardware, allowing the MCU to complete a TLS 1.2/1.3 handshake in milliseconds with the CPU mostly idle. The 1 MB Flash accommodates the TCP/IP stack, MQTT or CoAP client, and an X.509 certificate store. The Ethernet MAC plus optional USB 2.0 FS OTG allows simultaneous LAN connectivity and on-site configuration. Compared with a software-only crypto MCU, the hardware accelerator reduces handshake time and power consumption by approximately 5-10x.
Recommended
Building Automation Controller (BACnet, KNX/IP)
The PIC32MZ1024ECH100-I/PT is widely deployed in BACnet/IP and KNX/IP building-automation bridges. The dual CAN interfaces support HVAC zoning and elevator-lift controllers, the Ethernet MAC provides BACnet/IP networking, and the 512 KB SRAM allows a full BACnet stack plus scheduler table to reside on-chip. The 78 user I/O lines directly drive relay boards, triac optocouplers, and 0-10V analog lighting channels without an external I/O expander. The 200 MHz core comfortably runs the BACnet polling loop and trend-logging in deterministic sub-100 ms cycles.
Recommended
Industrial HMI / Touch Controller
Although the ECH sub-family lacks the FPU of the PIC32MZ EF, it still drives modest 4.3-inch WVGA TFT HMIs via the External Parallel Master Port (EPM). The 1 MB Flash accommodates the LVGL graphics library plus application pages, and the 512 KB SRAM hosts frame buffers and touch event queues. The integrated Ethernet MAC plus USB 2.0 FS OTG enables remote firmware updates. For higher-end graphics, Microchip recommends the PIC32MZ1024EFE100 (252 MHz with FPU), but the ECH100 is more cost-effective at basic HMI duty.
Recommended
Connected Medical Instrumentation
The PIC32MZ1024ECH100-I/PT is suitable for connected medical devices such as bedside monitors, infusion pump controllers, and point-of-care analyzers that require Ethernet connectivity and hardware-assisted security. The 200 MHz core samples ADC inputs at up to 1 MSPS via the dual 12-bit ADCs while simultaneously streaming processed data over Ethernet. The 1 MB Flash supports IEC 62304 software safety classification B/C, and the Hardware Crypto Accelerator enables HIPAA-compliant encrypted data transmission. Industrial temperature grade suits typical medical-environment specifications.
Recommended
Motor Control with CAN (Industrial Drives)
The PIC32MZ1024ECH100-I/PT handles Field-Oriented Control (FOC) for low-voltage industrial drives up to approximately 500 W. The dual CAN interfaces support CANopen DS301/DS402 profiles for servo and stepper drive communication, and the 200 MHz MIPS32 core executes the Park/Clarke transforms plus space-vector modulation at 20 kHz PWM rates. The dual 12-bit ADCs sample phase currents simultaneously with the hardware PWM triggers, minimizing CPU jitter. The 512 KB SRAM holds the speed-controller state and CANopen object dictionary, while Ethernet provides remote commissioning over a single twisted pair.

Key Differentiators
- Integrated 10/100 Ethernet MAC plus hardware Crypto Accelerator (vs STM32F407VGT6)
- Lower unit cost with double the SRAM (vs LPC4078FBD100)
- Drop-in same-package upgrade path to extended temperature grade (vs PIC32MZ1024ECG100-I/PT)
Design Notes
Decouple the PIC32MZ1024ECH100-I/PT with one 100 nF ceramic per VDD/VDDIO pin pair plus a single 4.7 uF bulk placed within 5 mm of the regulator. Place the bulk on the same layer as the MCU to minimize via inductance. If the internal LDO is bypassed and an external 1.8V core regulator is used, ensure PG (Power Good) is wired to a wake-capable input. Estimated: peak IDD is approximately 75 mA at 200 MHz with peripherals active.
Route the Ethernet RMII or RGMII pair to a 50-ohm single-ended impedance (or 100-ohm differential for RGMII) on the top layer beneath the MCU until the PHY footprint. Keep the RMII clock trace no longer than 50 mm and guard it with a continuous ground pour. The 50 MHz reference oscillator or 25 MHz crystal traces must be guarded and shorted to ground via stitching vias every 5 mm.
Do not assume all 78 RPOR pins are free at boot - the EPM, Ethernet, and USB peripherals consume dedicated pins (see pinout in manufacturer datasheet). Always consult the I/O multiplexing table before locking the PCB layout. The Hardware Crypto Accelerator only supports AES-128/192/256, SHA-1/256, and TDES - RSA/ECC are NOT supported in hardware and require software libraries (wolfSSL, mbedTLS) on the CPU. Estimated: software RSA-2048 sign operation takes approximately 150 ms at 200 MHz.
The PIC32MZ1024ECH100-I/PT in 100-pin TQFP package has a typical theta-JA of approximately 45 C/W on a standard 4-layer JEDEC test board. At full 200 MHz with all peripherals active (IDD approximately 75 mA), power dissipation is approximately 250 mW, yielding a junction temperature rise of only 11 C above ambient - well within the 85 C industrial limit. No heatsink is required.
Compliance Information
