PIC32MZ2048EFH100-I/PT Overview
What is a 32-bit microcontroller? A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, peripherals, and I/O on one die. 32-bit MCUs like the PIC32MZ EF family extend 8-bit/16-bit MCU capabilities with wider registers, hardware floating-point support, and substantially more memory bandwidth, allowing them to run real-time operating systems, advanced communication stacks (TCP/IP, USB, CAN), and complex signal-processing algorithms in parallel. The PIC32MZ EF family sits within Microchip's broader PIC32 -> MIPS32 -> 32-bit MCU hierarchy and is widely used as a drop-in modernizer for legacy PIC32MX designs.
Key features include dual-panel Flash enabling live-update firmware upgrades without production downtime, a 12-bit ADC with up to 48 channels and 500 ksps throughput, eight DMA channels that offload data movement from the CPU, and a 5V-tolerant I/O bank for direct interfacing to legacy industrial signals. The 2 MB program Flash is large enough to embed a full TLS 1.3 mbedTLS stack alongside an HTTP server while leaving room for a graphical HMI application.
The MCU uses Microchip's Super Scalar MIPS32 M-Class pipeline, achieving 1.53 DMIPS/MHz, and a 2 KB instruction cache plus 128 KB data RAM backed by a tightly-coupled Flash prefetch controller that masks Flash wait states. The integrated crypto engine accelerates AES-256 at >100 Mbps, and the 10/100 MAC includes IEEE 1588 timestamping hardware for industrial Ethernet protocols like EtherCAT or Profinet synchronization.
Typical applications include industrial IoT gateways combining Ethernet and USB, automotive infotainment HMI displays driven via the External Bus Interface (EBI) for TFT/LCD panels, multi-protocol sensor hubs aggregating UART/SPI/I2C/CAN traffic, motor-control FOC drivers, and graphics terminals. The 100-TQFP footprint offers 78 user I/O pins while remaining hand-solderable on 0.5 mm pitch, ideal for prototype runs and small-batch industrial SKUs.
When designing with this MCU, pay close attention to decoupling: place a 0.1 uF X7R ceramic on every VDD/VSS pair within 3 mm of the pins and a bulk 4.7-10 uF tantalum on the main 3.3 V rail. Respect the trace-length matching rules on Ethernet MII/RMII signals (typically 50 ohm controlled impedance, <50 ps skew) to meet IEEE 802.3 timing margins.

Typical Applications
PIC32MZ2048EFH100-I/PT is suitable for 6 applications: Industrial IoT Gateway, Automotive Infotainment HMI, Motor-Control FOC Driver, Multi-Protocol Sensor Hub, Graphics Terminal with TFT/LCD, USB Audio Class Streaming Device.
Industrial IoT Gateway
The PIC32MZ2048EFH100-I/PT is well-matched for industrial IoT gateways because its integrated 10/100 Ethernet MAC with IEEE 1588 timestamping and Hi-Speed USB 2.0 cut the BOM cost of an external bridge chip by approximately USD 2.50 per node. The 2 MB Flash can host Microchip's TCP/IP Lite stack plus an embedded TLS handshake library while leaving 1.2 MB free for application logic and MQTT publish buffers. The two CAN 2.0b controllers allow simultaneous Modbus TCP / CAN bridging for factory automation. The -40 C to +85 C industrial range covers most unheated cabinets without derating.
Recommended
Automotive Infotainment HMI
The 100-pin TQFP footprint delivers 78 user I/O pins, sufficient to drive an SPI TFT display panel plus a touch controller, rotary encoder inputs, and CAN bus from a single chip. The integrated 12-bit ADC at 500 ksps handles backlight dimming feedback and rotary-encoder quadrature decoding in parallel. The PIC32MZ2048EFH100's 330 DMIPS of integer performance decodes MP3/AAC streams in software with headroom for future codec upgrades without re-spinning the PCB. The -40 C to +85 C industrial temperature range covers most cabin environments; for under-hood use choose the AEC-Q100 qualified PIC32MZ2048EFH100-E variant.
Recommended
Motor-Control FOC Driver
The PIC32MZ2048EFH100's hardware FPU executes Field-Oriented Control (FOC) loops with 4 kHz to 16 kHz PWM update rates on a 200 MHz core, leaving >60% CPU idle margin for state-machine management. The 12-bit ADC's 48 channels, sample-and-hold synchronization triggered by PWM, and dual-compare trigger units enable simultaneous current and rotor-position sampling with less than 1 us of deterministic jitter. The 2 MB Flash is large enough to embed a full motor-tuning GUI and per-motor parameter storage without external EEPROM. The 100-pin TQFP gives 78 user I/O for three-phase gate driver, encoder, and fault-tree inputs.
Recommended
Multi-Protocol Sensor Hub
The PIC32MZ2048EFH100-I/PT integrates 6 UART, 4 SPI, and 5 I2C interfaces simultaneously, allowing one chip to aggregate radios (BLE, LoRa, Wi-Fi, GNSS), environmental sensors (BME280, SCD30), and storage (SD card, QSPI flash) on a single PCB. The 8-channel DMA offloads sensor polling from the CPU at 10 kHz aggregate throughput. The hardware crypto engine secures sensor-to-cloud handshakes using AES-256-GCM at >100 Mbps, fast enough to seal every TLS record without buffering.
Recommended
Graphics Terminal with TFT/LCD
The External Bus Interface (EBI) on the PIC32MZ2048EFH100-I/PT can drive a 16-bit TFT LCD in synchronous memory mode at up to 50 MHz, enough for QVGA/WQVGA panels up to 5.7 inch. The integrated 2 MB Flash can host a font atlas plus a GLCD-emulated library, replacing an external graphics controller. The 100-TQFP 78 user I/O pins allow SPI touch controller, keypad matrix scan, and PWM-driven backlight on the same bus without IO multiplexers.
Recommended
USB Audio Class Streaming Device
The Hi-Speed USB 2.0 controller on PIC32MZ2048EFH100-I/PT supports USB Audio Class 2.0 at 480 Mbps, enabling multichannel asynchronous audio streaming up to 192 kHz/24-bit. The hardware crypto engine provides DRM handshake acceleration for protected content delivery. The 512 KB SRAM acts as a double-buffered audio ring buffer (e.g., 4 ms of 8-channel 48 kHz audio = ~200 KB) with margin for resampling. This avoids external USB transceiver ICs and audio codecs with embedded USB in cost-sensitive consumer DAC SKUs.

Key Differentiators
- Highest-in-class 2 MB Flash + 512 KB SRAM on a single MIPS32 core (vs PIC32MZ1024EFE100-I/PT)
- Integrated hardware crypto engine saves an external companion chip (vs PIC32MZ2048ECH100-I/PT)
- Higher 250 MHz speed grade available on the same die (vs PIC32MZ2048EFH100-250I/PF)
Design Notes
Estimated: with all peripherals enabled and 200 MHz operation, the PIC32MZ2048EFH100 core draws up to ~110 mA from VDD. Place one 0.1 uF X7R 0402 ceramic per VSS/VDD pin pair within 3 mm of the package body, and add one 4.7 uF X5R 0805 bulk decoupling capacitor per side (top/bottom/left/right) of the 100-TQFP. Use a 10 uF tantalum polymer capacitor on the AVDD rail to filter ADC reference noise; AVSS must be tied to VSS at a single point to avoid ground loops.
The 100-pin TQFP package has a theta_JA of approximately 41 C/W on a 2-layer board with no airflow. At 110 mA and 3.3 V continuous draw (363 mW), the junction temperature rises ~15 C above ambient, well within the 85 C industrial limit. If the design uses sustained Ethernet MAC activity (~140 mA), expect a 35 C rise. For sealed enclosures above 60 C ambient, switch to the PIC32MZ EF family in 144-LQFP which has a more efficient bottom-exposed-pad thermal pad.
For Ethernet RMII/MII signals, route over a continuous ground reference plane with 50 ohm controlled impedance (typical microstrip: 0.20 mm trace on 0.20 mm dielectric above ground). Match trace lengths to within 50 ps (~5 mm) on the DDR-style RMII bus. Place the Ethernet PHY within 50 mm of the MCU, and use AC-coupling caps on the differential pairs only if the PHY datasheet explicitly requires them. For Hi-Speed USB, follow USB-IF stackup recommendations: 90 ohm differential impedance, 0.20 mm trace width on 0.20 mm dielectric.
1) Do not leave AVSS floating - the ADC reference ground must return to the same VSS plane as the digital ground at a single via. 2) Configure the unused Ethernet pins as digital outputs driven low; otherwise they enter high-impedance and burn extra shoot-through current. 3) The OSC1/OSC2 pins require a 12 MHz crystal with load capacitance matching the MCU's internal load spec; a 16 MHz crystal works but requires PLL settings changed in firmware. 4) Pin 1 (socket latch) is implicitly handled by the device orientation on the PCB - refer to JEDEC MS-026 for proper pin-1 identification.
