PIC32MZ1024EFH144T-I/PL Overview
A 32-bit MCU (microcontroller unit) is a single-chip computer that integrates a 32-bit processor core, program and data memory, and a rich set of peripherals into one package. Within the broader taxonomy, this PIC32MZ EF device sits in the hierarchy: microcontroller -> 32-bit MCU -> MIPS M-Class MCU -> PIC32MZ EF family -> embedded connectivity MCU -> semiconductor. This positioning places it between 8/16-bit legacy MCUs used for simple control and higher-end Cortex-M7 application processors used for advanced GUI and machine-learning workloads, making it well-suited for mid-range HMI, gateway, and industrial-automation designs.
Key features include 1 MB (1024 KB) of Flash, 512 KB of SRAM, a 12-bit ADC with up to 2 MSPS conversion rate, six UART, four SPI, four I2C, two CAN, USB 2.0 high-speed OTG, 10/100 Ethernet MAC, and a 120-pin (GPIO) count. The integrated FPU (floating-point unit) and DSP enhancements accelerate signal-processing tasks, while the dual-bank Flash and live-update capability support firmware-over-the-air (FOTA) upgrades common in IoT products.
The PIC32MZ EF architecture uses the MIPS M5150/M6240 core family, paired with a multi-channel DMA controller and a dedicated graphics controller for TFT/HMI panels. A separate crypto engine (when present, on EFH variant) accelerates AES, 3DES, SHA, and RNG primitives. The high-speed USB 2.0 OTG and 10/100 Ethernet MAC allow it to function as a connected-embedded host bridging sensors to the cloud.
Typical applications include industrial IoT gateways, automotive telematics and body controllers, and the device also fits smart energy metering where its 12-bit ADC at 2 MSPS and motor-control PWMs handle multiple sensor inputs simultaneously.
When laying out the PCB, ensure a 4-layer stackup with a continuous ground plane directly beneath the LQFP-144 to keep digital return paths short and to minimize EMI. Decouple VDD/VBATSS with 100 nF ceramic capacitors placed within 5 mm of every supply pin, and route the 12 MHz crystal traces as short, symmetric differential pairs with a guard ring.

Typical Applications
PIC32MZ1024EFH144T-I/PL is suitable for 6 applications: Industrial IoT Gateway, Automotive Telematics and Body Controller, Motor Control - 3-Phase BLDC/PMSM, HMI / TFT-LCD Touchscreen Panel, Smart Energy Meter / Data Concentrator, Medical Patient Monitor (Non-Safety).
Industrial IoT Gateway
The PIC32MZ1024EFH144T-I/PL's integrated 10/100 Ethernet MAC, USB 2.0 HS OTG, and dual CAN controllers make it a drop-in choice for industrial IoT gateways bridging RS-485 sensor networks to Ethernet/IP or MQTT backhauls. With 1 MB Flash it can hold a complete TLS 1.2/1.3 client stack, Modbus/TCP server, and FOTA bootloader simultaneously, while the crypto engine accelerates AES-256-CBC and SHA-256 hashing for authenticated TLS handshakes. The 200 MHz MIPS M5150 core delivers ample compute for local sensor aggregation and rule-based edge analytics before forwarding to the cloud.
Recommended
Automotive Telematics and Body Controller
The PIC32MZ1024EFH144T-I/PL fits automotive telematics and body-control modules thanks to its industrial -40 C to +85 C rating, dual CAN 2.0B controllers for OBD-II and CAN-FD traffic, and 120 GPIO for driving lights, locks, and HVAC actuators. The 12-bit ADC at 2 MSPS samples wheel-speed, temperature, and battery-voltage signals with sufficient margin for CAN-bus diagnostics, while the 512 KB SRAM buffers diagnostic-trouble-code (DTC) logs between write cycles. Although not AEC-Q100 qualified, this industrial-grade part is widely used in non-safety body-electronics designs that do not require the full automotive certification.
Recommended
Motor Control - 3-Phase BLDC/PMSM
For 3-phase brushless DC and permanent-magnet synchronous motor control, the PIC32MZ1024EFH144T-I/PL provides six high-resolution PWM channels, a 2 MSPS 12-bit ADC for current sensing, and MIPS DSP extensions that execute field-oriented control loops within a single PWM period. Its 1 MB Flash holds the motor-control algorithm plus a UI layer and FOTA bootloader, while the 512 KB SRAM buffers the 32 KB control loop and the data-acquisition ring without contention. The LQFP-144 20x20 mm package supplies 120 GPIO to drive up to two 3-phase bridges simultaneously for dual-axis servo or traction control applications.
Recommended
HMI / TFT-LCD Touchscreen Panel
The PIC32MZ1024EFH144T-I/PL can drive a small- to mid-size TFT-LCD panel (up to WVGA) through its integrated graphics controller, EBI bus, and dedicated TFT timing engine, with the MIPS32 M5150 core rendering UI frames in RAM-backed framebuffers. The 1 MB Flash stores fonts, icons, and a complete Microchip Harmony GUI application, while 512 KB SRAM holds two full-screen 16-bit-per-pixel framebuffers for tear-free animation. With 120 GPIO available, the design can also drive a resistive or capacitive touch controller, RGB LEDs, and physical buttons without external I/O expanders.
Recommended
Smart Energy Meter / Data Concentrator
For smart-meter and data-concentrator designs, the PIC32MZ1024EFH144T-I/PL brings a 12-bit ADC at 2 MSPS to digitize multi-channel current/voltage sensing, plus 1 MB Flash for DLMS/COSEM or IEC 62056 protocol stacks. The 512 KB SRAM buffers metering data between WAN uplink transmissions (typically on PLC or sub-GHz wireless), while the 10/100 Ethernet MAC and USB OTG enable optional local-area connectivity for utility-side diagnostics. The -40 C to +85 C industrial temperature range and 2.1 V to 3.6 V supply tolerance cover typical outdoor meter environments without extra regulation.
Recommended
Medical Patient Monitor (Non-Safety)
In non-safety medical monitors such as non-invasive blood-pressure cuffs, pulse-oximeter modules, and home spirometers, the PIC32MZ1024EFH144T-I/PL integrates USB OTG, the crypto engine for authenticated firmware, and 12-bit ADC at 2 MSPS to digitize sensor waveforms with adequate resolution. The 1 MB Flash holds the entire application including a Micrium/Microchip Harmony RTOS kernel, USB device-class drivers, and a 32 KB DSP filter library for SpO2/heart-rate extraction. Although not IEC 60601 qualified, the industrial temperature range and EMC-robust LQFP-144 package suit non-life-supporting consumer medical products.

Design Notes
The PIC32MZ1024EFH144T-I/PL requires multiple dedicated supply rails (VDD, AVDD, VBAT, VUSB3V3) and each pin must be decoupled individually with a 100 nF ceramic capacitor placed within 5 mm of the supply pin and a 4.7 uF bulk capacitor near the package. The high-speed USB PHY additionally requires a 1 uF + 100 nF pair on the VUSB3V3 rail, and the ADC analog supply (AVDD) should be filtered through a ferrite bead from VDD to maintain 12-bit ADC accuracy. Under-estimate: at 200 MHz with peripheral DMA active, typical VDD current is around 70-90 mA, peaking briefly to 120 mA during Flash erase cycles.
Although the LQFP-144 20x20 mm package has a reasonable 38 C/W theta-JA on a 4-layer JEDEC test PCB, industrial designs often mount on a 2-layer board with smaller copper area, which can push theta-JA above 60 C/W. Estimate: at 90 mA active current with VDD = 3.3 V, internal dissipation is roughly 300 mW, yielding a junction rise of 18 C above ambient on the JEDEC board but 35 C on a 2-layer board. Provide at least 4 thermal vias under the exposed die-pad (the LQFP-144 PL suffix on Microchip parts has no thermal pad, so connect all GND pins to a continuous ground plane instead).
Route the 12 MHz primary crystal and 32.768 kHz secondary crystal traces as short, symmetric pairs (less than 5 mm, 0.2 mm wide) with a continuous guard ring tied to ground. Keep all switching signals (especially USB D+/D-, Ethernet RMII, and SPI flash) at least 3 mm away from the analog inputs (AN0-AN47), and route the USB D+/D- differential pair with 90 ohm impedance and length-matching to within 150 mil. The SD card interface, if used, requires its clock trace length-matched to the data lines within 25 mil. Microchip's ANAC2945 app note shows a reference layout for the PIC32MZ EF family that should be followed for USB-IF compliance.
Three common pitfalls on PIC32MZ EF designs: (1) leaving the BOOT pin floating at reset - tie it to VDD via 10 kohm for normal boot or to GND for bootloader; (2) using the 32.768 kHz crystal on SOSC without also configuring the RTC and SOSC bias trimming register, which can cause 2-5% timing drift; (3) forgetting to enable the JTAG or SWD debugger pins (TCK/TMS/TDO/TDI) - on the LQFP-144 these are multiplexed with GPIO so firmware must release them before debugging works.
