PIC32MZ1024ECH064-I/MR - 200MHz 1MB Flash MCU | Microchip
MPN： PIC32MZ1024ECH064-I/MR ✓ 啟用中PIC32MZ1024ECH064-I/MR 概覽
A microcontroller (MCU) is a single-chip computer integrating a CPU core, non-volatile program memory (Flash), volatile data memory (SRAM), and a rich set of peripherals on one die. The PIC32MZ EC family belongs to Microchip's high-performance MIPS32 line, with the ECH variant emphasizing embedded connectivity (Ethernet + CAN + USB) for industrial HMI, IoT gateways, and audio/graphics products. Within the power management and embedded hierarchy: microcontroller -> embedded MCU -> 32-bit MCU -> PIC32MZ family.
Key specifications include 200 MHz core with 2.5 MB dual-panel live-update Flash (1 MB primary + 1 MB secondary), 512 KB SRAM, 53 selectable I/O lines, eight hardware-programmable DMA channels plus 16 dedicated DMA channels, a 12-bit 5 MSPS ADC with up to 48 channels, four I2S/SPI audio interfaces, an integrated graphics LCD controller, and Peripheral Pin Select (PPS) for flexible function remapping.
The architecture combines a 5-stage MIPS32 microAptiv pipeline with tightly-coupled SRAM and dedicated DMA, achieving deterministic real-time response at full 200 MHz while the dual-panel Flash allows field firmware upgrades without downtime. On-chip regulators and brown-out reset simplify power design at 3.3 V typical operation.
Typical applications include industrial IoT gateways, Ethernet-enabled motor controllers, automotive infotainment head units, HMI panels with graphics LCD, audio processing (I2S/USB streaming), medical instrumentation, and USB device/host peripherals.
For PCB layout, route the Ethernet MII/RMII differential pairs with 100-ohm impedance and length matching, place the 24 MHz crystal traces short and symmetric, and provide a solid ground plane under the exposed pad for thermal dissipation of up to 2 W continuous operation.

典型應用
PIC32MZ1024ECH064-I/MR 適用於 7 應用s: Industrial IoT Gateway with Ethernet, Automotive Infotainment Head Unit, HMI Panel with Graphics LCD, USB Audio Streaming Device, Motor Control with CAN Bus, Medical Instrumentation Data Logger, Smart Home Edge Controller.
Industrial IoT Gateway with Ethernet
The PIC32MZ1024ECH064-I/MR's integrated 10/100 Ethernet MAC, 512 KB SRAM, and 200 MHz MIPS32 core make it ideal for industrial IoT gateways aggregating Modbus TCP, MQTT, and CAN bus traffic. With 1 MB Flash it runs a full TCP/IP stack (TCP, UDP, HTTP, TLS) plus application logic without external memory. The 53 PPS-remappable I/Os free unused peripherals for SPI sensors, I2C EEPROMs, and UART modems. Brown-out reset and wide 2.3-3.6 V input tolerate noisy 24V-derived 3.3V rails typical in factory automation.
推薦
Automotive Infotainment Head Unit
The PIC32MZ1024ECH064-I/MR delivers the 200 MHz processing needed for automotive infotainment touchscreens, USB media streaming (HS USB 2.0 Host), and Bluetooth handoff. Its integrated graphics LCD controller drives 4-7 inch WVGA TFT panels directly, eliminating external display ICs. The dual-panel live-update Flash enables OTA-style firmware upgrades without bricking the unit - critical for automotive recall-free updates. For AEC-Q100 grade designs, select the /E/MR variant (-40C to +125C).
推薦
HMI Panel with Graphics LCD
The PIC32MZ1024ECH064-I/MR's on-chip graphics LCD controller supports TFT panels up to SVGA-class with parallel RGB interface, while 512 KB SRAM holds frame buffers without external memory. Combined with PPS, the same silicon drives a touchscreen controller, an encoder input, and a Wi-Fi companion module via UART. The MIPS32 microAptiv core executes LVGL or emWin graphics stacks at full 30 FPS on QVGA panels. Compact 9x9 mm VQFN footprint enables slim-panel mechanical designs.
推薦
USB Audio Streaming Device
The PIC32MZ1024ECH064-I/MR's HS USB 2.0 Device port delivers 480 Mbps throughput for multi-channel USB Audio Class 2.0 streaming at 96 kHz / 24-bit. Four I2S ports connect directly to external DACs and ADCs (e.g., PCM1794A, CS5343), while DMA channels offload sample movement from the CPU. The 200 MHz MIPS32 core sustains ASIO low-latency buffer handling. Integrated 12-bit ADC handles microphone bias monitoring and side-tone mixing.
推薦
Motor Control with CAN Bus
The PIC32MZ1024ECH064-I/MR's 200 MHz core executes field-oriented control (FOC) loops on three-phase BLDC/PMSM motors at 20 kHz PWM while simultaneously handling CANopen or DeviceNet traffic over its integrated CAN 2.0B peripheral. PPS remaps PWM outputs to any GPIO, simplifying PCB layout. The 12-bit 5 MSPS ADC samples three-phase currents with sub-microsecond conversion latency. 1 MB Flash stores firmware plus lookup tables for sensorless startup algorithms.
推薦
Medical Instrumentation Data Logger
The PIC32MZ1024ECH064-I/MR is well-suited to medical data loggers (subject to IEC 60601 compliance certification by the integrator). Its 12-bit 5 MSPS ADC captures multi-channel physiological signals (ECG, SpO2, temperature) while Ethernet MAC streams to a hospital network in HL7 or MQTT format. 1 MB Flash stores hours of waveform data during network outages; 512 KB SRAM buffers real-time samples. Wide -40C to +85C operating range supports portable clinical environments.
推薦
Smart Home Edge Controller
The PIC32MZ1024ECH064-I/MR consolidates Wi-Fi, Zigbee, Thread, and Matter bridge functions into one chip with its Ethernet backbone. HS USB 2.0 supports local mass storage, CAN 2.0B integrates HVAC and EV-charger subnets, and 1 MB Flash runs the full Matter stack plus local automation rules. The graphics LCD controller drives a 3.5-inch touchscreen for in-wall control panels. PPS flexibility means a single PCB design supports multiple SKU variants by firmware alone.

設計說明
The PIC32MZ1024ECH064-I/MR operates from a single 2.3-3.6 V supply with on-chip voltage regulators generating the 1.2 V core rail. Decouple VDD pins with one 100 nF ceramic per pin and one bulk 10 uF tantalum near the package. Power sequencing is not required. For Ethernet and USB operation, total active current can reach 130 mA at 200 MHz with all peripherals enabled - budget for 200 mA peak.
Estimated: At 200 MHz full peripheral load, the PIC32MZ1024ECH064-I/MR dissipates approximately 400 mW internally. The 64-VQFN (MR) exposed pad has a theta_JA of ~28 C/W on a 4-layer JEDEC test board, giving ~11C rise at 400 mW. For continuous industrial operation up to 85C ambient, ensure the exposed pad has at least 25 vias to the internal ground plane for adequate heat spreading.
Route the 50-ohm RMII Ethernet differential pairs (RX+/-, TX+/-) with controlled impedance and length matching within 150 mils. Place the 24 MHz crystal traces short (< 5 mm), symmetric, and guard-traced; keep the analog AVSS/AVDD pair clean from digital return currents. The exposed pad must be soldered to a continuous ground plane with a thermal via array (0.3 mm pitch recommended).
Do not skip the 10 uF bulk capacitor on VDD - the internal regulator requires this for stability under USB inrush. Avoid running the ADC with the digital I/O switching on adjacent pins without proper ground isolation. The MCLR pin needs a 10 kohm pull-up to VDD for normal operation; if left floating, the part will not exit reset.
The HS USB 2.0 D+/D- lines require 90-ohm differential impedance with no stubs; place the 27 ohm series source termination resistors close to the PIC32MZ pins. The USB bus voltage detection pin (VBUS) must be connected to the VBUS rail with a 10 kohm pull-down. For Ethernet, place the 1:1.41 center-tapped magnetics within 25 mm of the PHY, not the MAC.
