PIC32MZ1024ECH124-I/TL Overview
A 32-bit microcontroller (MCU) is an integrated circuit that combines a high-performance processor core, program and data memory, and a configurable peripheral set on a single die. The PIC32MZ ECH family belongs to Microchip's premium performance tier of 32-bit MCUs, sitting within the broader PIC32 -> MIPS architecture -> microcontroller -> embedded processor hierarchy. This positions the part for applications that demand high-throughput DSP, large RAM-resident data buffers, and full-speed wired connectivity, while remaining programmable through the MPLAB Harmony v3 framework.
Key differentiators include Peripheral Pin Select (PPS) for flexible function remapping, eight hardware-programmable DMA channels plus sixteen dedicated DMA channels with automatic data-size detection, hardware crypto/hash engines, and a 12-bit 18 MSPS ADC with up to 48 analog inputs. The integrated FPU, MPU, and trace/debug ports make the device suitable for safety-conscious designs and for code development with MPLAB X IDE.
Technically, the part uses a superscalar 32-bit MIPS core with a 5-stage pipeline and dual-issue capability at 200 MHz. The dual-panel Flash architecture permits read-while-write field upgrades, and the 512 KB SRAM allows large TCP/IP, USB, or graphics frame buffers to be held on-chip. The 124-pin VTLA EP package exposes the maximum GPIO count of this family while the exposed pad provides low thermal resistance for industrial-grade operation.
Typical applications include industrial Ethernet gateways, building-automation controllers, automotive infotainment head units, multi-protocol industrial sensor hubs, and high-speed HMI/graphical displays. Designers choose this part when deterministic 200 MHz throughput, 1 MB code space, and integrated Ethernet/CAN connectivity are required without an external PHY complexity tax.
Design consideration: place decoupling capacitors (100 nF + 1 µF) within 2 mm of every VDD/VSS pair and connect the central exposed pad to a continuous ground plane for thermal dissipation. Confirm that the chosen PHY and CAN transceiver share a common 3.3 V rail to avoid level shifters.

Typical Applications
PIC32MZ1024ECH124-I/TL is suitable for 6 applications: Industrial Ethernet Gateway, Building Automation Controller, Automotive Infotainment Head Unit, Multi-Protocol Industrial Sensor Hub, Graphical HMI Display, Secure IoT Edge Node.
Industrial Ethernet Gateway
The PIC32MZ1024ECH124-I/TL is well suited for industrial Ethernet gateways because it integrates a 10/100 Mbps Ethernet MAC, dual CAN 2.0B controllers, and 512 KB of SRAM capable of holding full TCP/IP and Modbus TCP stacks on-chip. At 200 MHz the MIPS microAptiv core delivers 330 DMIPS, which is sufficient to handle real-time protocol conversion between Modbus, EtherNet/IP, and MQTT without external coprocessors. Designers place an external 10/100 PHY on the dedicated RMII/RGMII pins and route the CAN transceivers to isolated bus pins. The 1 MB dual-panel Flash with live-update support permits secure OTA firmware upgrades while the gateway continues to forward traffic.
Recommended
Building Automation Controller
Building-automation controllers benefit from the PIC32MZ1024ECH124-I/TL's large 512 KB SRAM for BACnet or LonWorks stack buffering and its 97 programmable I/O for digital and analog sensor interfacing. The 12-bit 18 MSPS ADC with up to 48 channels enables direct connection to multiple temperature, pressure, and humidity sensors without an external multiplexer. Peripheral Pin Select (PPS) allows the designer to remap UART, SPI, and I2C functions to any available I/O pin, simplifying PCB layout for complex HVAC controllers. The part operates across -40 to +85 °C industrial temperature ranges, suitable for plenum-rated enclosures and outdoor equipment housings.
Recommended
Automotive Infotainment Head Unit
The PIC32MZ1024ECH124-I/TL can drive automotive infotainment head unit HMI subsystems where it manages CAN bus communication, audio routing, and display refresh. The 200 MHz MIPS core and 512 KB RAM are sufficient to drive small QVGA/WQVGA TFT displays with custom GUIs while simultaneously handling CAN 2.0B traffic from the vehicle body controller. Six SPI modules at 50 Mbps allow connection to external audio codecs, radio tuners, and SD card storage. Designers should pair this MCU with a dedicated LCD controller and audio DAC for full multimedia capability, and select the E/TL extended-temperature variant for cabin-temperature operation.
Recommended
Multi-Protocol Industrial Sensor Hub
Multi-protocol sensor hubs aggregate data from RS-485, RS-232, CAN, and Ethernet sensors and the PIC32MZ1024ECH124-I/TL handles all of these interfaces on-chip. Six UART modules (25 Mbps with LIN 1.2 and IrDA support) plus six 4-wire SPI modules allow concurrent master/slave connections to multiple industrial sensor strings. The 8+16 DMA channels with automatic data-size detection move samples between peripherals and memory without CPU intervention, preserving the 330 DMIPS budget for protocol parsing. The 1024 KB Flash accommodates firmware for multiple stack variants that can be selected at runtime via the dual-panel live-update mechanism.
Recommended
Graphical HMI Display
Graphical HMI displays benefit from the PIC32MZ1024ECH124-I/TL's large 512 KB SRAM which can host full frame buffers for 4.3-inch WQVGA TFT panels without external memory. The 200 MHz MIPS core with hardware FPU accelerates image scaling, alpha blending, and touch-input processing. The integrated 12-bit ADC digitizes resistive touch-screen coordinates directly, while six SPI peripherals drive the TFT controller, NOR Flash for assets, and SD card for data logging. PPS remapping simplifies the multi-bus PCB layout required for compact HMI modules. The VTLA-124 exposed pad provides low thermal resistance for enclosed fan-less housings.
Recommended
Secure IoT Edge Node
Secure IoT edge nodes leverage the PIC32MZ1024ECH124-I/TL's hardware crypto acceleration, large Flash for TLS libraries, and integrated Ethernet MAC for cloud connectivity. The 512 KB SRAM is enough to hold TLS session keys and MQTT message buffers, while the 1 MB Flash stores application firmware, certificates, and OTA staging images. The 200 MHz core executes TLS handshakes in milliseconds, and the dual-panel Flash architecture allows secure in-field firmware upgrades with rollback. Designers pair this MCU with an external secure element for root-of-trust and use PPS to remap GPIO for tamper-detection inputs.

Key Differentiators
- 124-pin VTLA EP package with maximum GPIO and exposed thermal pad (vs PIC32MZ1024ECH100T-I/PT)
- Integrates 10/100 Ethernet MAC on-chip (vs PIC32MZ1024ECG100T-I/PF)
- Dual-panel Flash with live-update support (vs PIC32MX795F512L-80I/TL)
Design Notes
Place a 100 nF ceramic decoupling capacitor within 2 mm of every VDD/VSS pair and add a bulk 10 µF tantalum or polymer capacitor near the part's exposed pad. The PIC32MZ1024ECH124-I/TL has 18 VDD and 18 VSS pins distributed around the 124-VTLA package; all must be connected to a continuous low-impedance power plane. The dual-panel Flash live-update feature requires a stable 3.3 V rail within ±3 % tolerance during flash writes to avoid corruption - verify the LDO/dCDC converter's transient response at full 200 MHz operation.
Connect the central exposed pad of the 124-pin VTLA EP package to a continuous ground plane with a minimum 9-thermal-via array (3x3, 0.3 mm drill) to dissipate the 200 MHz operation heat. The VTLA EP's exposed pad provides the primary thermal path; without adequate thermal vias, junction temperature can exceed 105 °C during sustained cryptographic operations. Estimate: at 3.3 V VDD and 200 MHz full-load CPU utilization, the part draws approximately 130 mA (≈ 0.43 W), requiring a thermal resistance below 35 °C/W for safe industrial operation.
Route the 50 MHz SPI signals (SPI1-SPI6) as impedance-controlled 50 Ω traces with ground reference and keep trace length mismatch below 2 mm for SPI clock/data pairs. Use a 4-layer PCB with continuous ground plane under the MCU to minimize EMI. The Ethernet MAC signals (RMII/RGMII) require 50 Ω controlled-impedance traces with length matching within 50 mils; route these away from switching power converters and keep them on the top layer over a continuous ground plane. Northern Software's documentation notes that PGEC1/PGED1 and PGEC2/PGED2 are ICSP pairs - both signals of the same pair must be used together (mixing PGEC1 with PGED2 will fail to program).
Do not use the 'E' temperature-grade PIC32MZ1024ECH124-E/TL as a drop-in for new industrial designs without verifying all peripherals - the E-grade part targets -40 to +125 °C extended operation and may have slightly different ADC linearity. Avoid using the internal 8 MHz FRC for USB or Ethernet - the precision is insufficient for HS USB PLL lock. Always configure the JTAG/ICSP pins as GPIO in firmware before disabling the programming interface, otherwise debug recovery requires the dedicated programming tool. The peripheral pin select (PPS) registers lock when IOLOCK is set - re-enable IOLOCK after configuration to prevent accidental remapping at runtime.
Compliance Information
RoHS compliant per Microchip product page. Lead-free (Pb-free) reflow profile per JEDEC J-STD-020. Industrial temperature grade (I/TL) operates -40 to +85 °C; extended grade (E/TL) operates -40 to +125 °C for automotive applications.
