PIC32MZ1024EFH144T-I/PH Overview

The Microchip Technology PIC32MZ1024EFH144T-I/PH is a high-performance 32-bit MIPS M-Class microcontroller running up to 200 MHz, integrating 1 MB of Flash and 512 KB of SRAM in a 144-pin TQFP (16x16 mm) package. It belongs to the PIC32MZ EF family, which combines a MIPS32 M-class core with FPU, dedicated audio and graphics peripherals, Hi-Speed USB, Ethernet MAC, and advanced analog blocks targeting connectivity-rich applications.

A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals (timers, communication interfaces, ADCs, GPIO) into one IC. Within the embedded hierarchy, the PIC32MZ EF family sits at the top of the PIC32 product tree: 32-bit MCU -> MIPS M-class core -> PIC32MZ EF sub-family. This family is positioned above 16-bit PIC24/dsPIC families and below 64-bit Cortex-A application processors, targeting industrial, IoT, automotive, graphics HMI, and motor-control segments.

Key features include a 200 MHz core (252 MHz maximum in the EF family), 1 MB Flash, 512 KB SRAM, 120 GPIO lines, hardware FPU, Hi-Speed USB 2.0 OTG, 10/100 Ethernet MAC, multiple CAN, I2C, SPI, and UART ports. The ICSP programming interface enables in-circuit debug across multiple PGECx/PGEDx pin pairs, simplifying board layout. Wide supply voltage (2.1V to 3.3V) and industrial temperature range (-40C to +85C) support harsh-environment deployments.

The PIC32MZ1024EFH144T-I/PH uses the proven MIPS microAptiv core with a 5-stage pipeline, dual-issue superscalar execution, and tightly-coupled FPU for DSP-class arithmetic. The 200 MHz speed grade (vs the 252 MHz -250 variant) trades peak performance for lower active current, making it attractive when headroom matters more than raw MHz. Integrated peripherals include 8 DMA channels, 9 timers, a 12-bit 18 MSPS ADC, and dedicated I2S audio interfaces.

Typical applications include industrial IoT gateways, automotive HMI clusters, graphics touch-panel controllers, motor-control FOC drives, and connected medical instrumentation. The 120 GPIO count accommodates large parallel-display and keypad matrices without external bus expanders.

Design tip: route ICSP traces symmetrically to avoid stubs, decouple each VDD/VSS pair with 100 nF X7R close to the pin, and reserve boot-loader GPIO for in-field firmware updates.

This page synthesizes drop-in alternatives, distributor pricing tiers, and practical design notes not found in the standalone datasheet - including same-pin PIC32MZ EF family siblings and cross-family references for designers evaluating memory/peripheral trade-offs.

Industrial Sensor Hub

Industrial sensor hubs aggregating multiple analog and digital sensors leverage the PIC32MZ1024EFH144T-I/PH's mix of 120 GPIO, 12-bit 18 MSPS ADC, multiple I2C/SPI ports, and CAN interface. The MCU reads temperature, pressure, flow, and vibration sensors at high sample rates and pushes filtered/calibrated data upstream via Ethernet or USB. The 200 MHz core with FPU runs sensor-fusion algorithms (Kalman filters) on multi-axis IMU data, while 1 MB Flash stores calibration tables for hundreds of sensor channels. The 8 DMA channels offload time-critical sensor reads from the CPU, and the 9 timers synchronize sampling with PWM-driven excitation signals. Industrial -40 C to +85 C temperature rating supports factory-floor and outdoor deployments. Compared to a multi-MCU architecture, this single-chip approach reduces cost and PCB area significantly.

Where to find the PIC32MZ1024EFH144T-I/PH pinout diagram?

The pinout diagram for the 144-pin TQFP (PH) package is in the Microchip PIC32MZ1024EFH144 datasheet's package pinout section, including alternate ICSP function assignments. The package uses 16x16 mm body with 0.5 mm pitch. Pin 1 is identified by a corner marker and orient the chip with the dot at the top-left of the PCB footprint.

Is PIC32MZ1024EFH144T-I/PH the same as PIC32MZ1024EFG144T-I/PH?

No, the PIC32MZ1024EFH144T-I/PH and PIC32MZ1024EFG144T-I/PH are not the same. Both share the 144-pin TQFP package, 200 MHz core, 1 MB Flash, and 512 KB SRAM, but the 'G' suffix indicates an integrated crypto engine (AES, SHA, TRNG) that the 'H' version lacks. They are pin-compatible but functionally different for security workloads.

These come from the Microchip datasheet retrieved 2026-10-04.

What is the lead time for PIC32MZ1024EFH144T-I/PH?

As of 2026-10-04, DigiKey lists the PIC32MZ1024EFH144T-I/PH as 'ships today' for low quantities, and Mouser reports immediate stock. LCSC, Onzuu, and Veswin all show in-stock inventory. For production volumes of 1000+ units, distributors typically quote 6-12 week lead time direct from Microchip factory stock.

Can PIC32MZ1024EFG144T-I/PH replace PIC32MZ1024EFH144T-I/PH?

Yes, PIC32MZ1024EFG144T-I/PH can replace PIC32MZ1024EFH144T-I/PH because both share the same 144-pin TQFP footprint and same Flash/SRAM. However, note that the G variant adds an integrated crypto engine which is a superset capability, not a replacement risk. For applications that don't use crypto, the G variant is functionally backward-compatible at the pin level.

Design Notes

Place a 100 nF X7R ceramic decoupling capacitor on every VDD/VSS pin pair within 2 mm of the package. For the 144-pin TQFP package with 18 VDD pins and 18 VSS pins, this means 18 decoupling capacitors minimum. Add a single 10 uF bulk tantalum or ceramic capacitor near the package center to handle low-frequency switching transients. Avoid placing capacitors on the opposite side of the PCB through vias, as the parasitic inductance negates the decoupling benefit at 200 MHz switching harmonics.

Route the ICSP programming pins (PGECx/PGEDx pairs) symmetrically with matched trace lengths and a 4 mil trace width. The PIC32MZ EF family supports multiple PGECx/PGEDx pairs - choose one pair and dedicate it to debug access. Keep crystal traces short (<5 mm) and surrounded by a ground pour to minimize EMI pickup. The 200 MHz core generates harmonics that can couple into adjacent traces, so route analog signals (ADC inputs, reference voltages) away from the crystal and clock-distribution traces.

Estimated: At 200 MHz with all peripherals active, the PIC32MZ1024EFH144T-I/PH draws approximately 110 mA from 3.3V, dissipating 363 mW. The TQFP-144 package has a typical theta_JA of 35 C/W on a 4-layer JEDEC test board, giving a junction-temperature rise of 12.7 C above ambient. At +85 C industrial ambient, the junction reaches 97.7 C, which is within the 125 C maximum. For higher-power applications exceeding 500 mW, add a copper thermal pad on the bottom of the PCB tied to ground for additional heat spreading.

Do not exceed the 3.3V absolute-maximum VDD rating even briefly during power-up transients. Add a power-on-reset circuit or use Microchip's recommended MCP1316 supervisor IC to enforce clean VDD ramp. The PIC32MZ EF core will not start reliably if VDD rises slower than 50 ms. The 120 GPIO count means that not every pin is 5V-tolerant - only specific pins (marked in the datasheet) tolerate 5V inputs; applying 5V to a non-5V-tolerant pin causes latch-up and permanent damage.
