PIC32MZ1024EFK144-I/PH Overview
A 32-bit microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, and a rich set of peripherals. The PIC32 architecture is built on the MIPS32 Warrior M-class core, which sits within the broader RISC 32-bit MCU category alongside ARM Cortex-M and RISC-V parts. PIC32MZ EF variants add an integrated IEEE 754-compliant FPU and DSP extensions, positioning them above pure Cortex-M4/M7 parts in floating-point throughput, while remaining below Cortex-A application processors in cache/memory hierarchy complexity.
Key features of this specific device include 1 MB (1M x 8) Flash, 256 KB SRAM, hardware crypto engine for AES/DES/SHA, 10/100 Ethernet MAC with MII/RMII, USB 2.0 High-Speed OTG, six UART, four SPI, two I2C, two CAN 2.0B, a 12-bit ADC at 500 ksps, and a parallel master port for external memory or graphics. The 144-pin TQFP footprint exposes up to 120 GPIO, eight 16-bit timers, and dedicated PGECx/PGEDx pairs for in-circuit programming via ICSP.
Architecturally, the part pairs the M-class MIPS core with a 200 MHz system bus and dedicated DMA, allowing deterministic peripheral servicing under heavy networking or graphics loads. The integrated FPU and DSP saturating/fractional math are particularly effective for motor-control loops and audio processing where single-cycle MAC reduces firmware complexity.
Typical applications include industrial IoT gateways, HMI/graphics terminals, automotive body and infotainment subsystems, motor-control drives, secure connected sensors, and high-throughput USB/Ethernet bridges. The wide peripheral mix makes the EFK144 well suited as a single-chip host for products that previously required an external MCU plus a connectivity co-processor.
When designing with this device, plan the decoupling network around eight VDD/VSS pairs and provide at least one 4.7 uF bulk capacitor near the VCAP pin. Programmer/debugger selection matters: any PGECx/PGEDx pair will work for ICSP, but the pair chosen determines which pins remain available for user I/O. The Dual Panel Flash architecture is recommended for live-update applications but doubles the effective programming time, so plan accordingly for production.

Typical Applications
PIC32MZ1024EFK144-I/PH is suitable for 6 applications: Industrial IoT Gateway, HMI and Graphics Terminals, Motor Control Drives, Automotive Body and Infotainment Subsystems, Secure Connected Sensors, High-Throughput USB/Ethernet Bridge.
Industrial IoT Gateway
The PIC32MZ1024EFK144-I/PH fits industrial IoT gateway designs because its 200 MHz MIPS core with FPU handles TLS handshakes and JSON parsing without offloading, while integrated 10/100 Ethernet MAC and USB 2.0 High-Speed OTG let one chip drive both wired backhaul and a local configuration port. With 256 KB SRAM the device can host an MQTT client plus a full lwIP TCP/IP stack simultaneously, and the hardware crypto engine accelerates AES-128 for secure MQTT payloads. Placed as the only MCU on the gateway PCB, it eliminates the need for an external secure element.
Recommended
HMI and Graphics Terminals
For HMI and graphics terminals, the PIC32MZ1024EFK144-I/PH pairs its 330 DMIPS throughput with the parallel master port to drive a TFT LCD without an external graphics controller. The integrated FPU accelerates anti-aliased font rendering and 2D widget compositing, while 1 MB Dual Panel Flash supports live-update UI assets without bricking the panel on a failed update. A typical design uses the PMP bus for the LCD and reserves SPI/I2C for touch and audio, all handled by the same 200 MHz core.
Recommended
Motor Control Drives
The PIC32MZ1024EFK144-I/PH suits BLDC and PMSM motor-control drives because its single-cycle MAC and 64-bit DSP accumulators run field-oriented control loops inside a 5 microsecond cycle at 200 MHz. The dual CAN 2.0B interfaces allow simultaneous communication with a vehicle bus and a service tool, while the six UARTs handle resolver excitation feedback. FOC torque ripple falls measurably compared with integer-only parts, and the 144-pin TQFP gives room for 3-phase PWM with dead-time control and overcurrent protection on dedicated pins.
Recommended
Automotive Body and Infotainment Subsystems
The PIC32MZ1024EFK144-I/PH can serve automotive body controllers and entry-level infotainment nodes where the industrial -40C to +85C grade suffices for cabin environments. Its dual CAN 2.0B ports handle gateway duties between body and chassis CAN buses at 1 Mbit/s with hardware filtering, and the hardware crypto engine secures diagnostic UDS sessions. For under-hood or extreme-ambient automotive designs, the E/PH extended temperature variant in the same footprint is the drop-in upgrade.
Recommended
Secure Connected Sensors
For secure connected sensors, the PIC32MZ1024EFK144-I/PH combines AES-128/DES/SHA hardware acceleration with 10/100 Ethernet or USB High-Speed for authenticated telemetry. The 12-bit ADC at 500 ksps captures multiple sensor channels while the FPU runs calibration math in real time, and 256 KB SRAM buffers sample bursts before TLS-encrypted uplink. Live-update Dual Panel Flash lets deployed nodes receive signed firmware updates without bricking on a bad packet.
Recommended
High-Throughput USB/Ethernet Bridge
The PIC32MZ1024EFK144-I/PH works as a USB-to-Ethernet or USB-to-CAN bridge because it exposes both USB 2.0 High-Speed OTG and 10/100 Ethernet MAC plus dual CAN on the same die. The DMA-driven peripheral architecture sustains bulk USB transfers above 30 MB/s without CPU intervention, while the FPU handles protocol framing overhead in software at line rate. Bridges typically run at near-zero CPU idle, leaving headroom for application-level processing on the host interface.

Key Differentiators
- Industry-leading integrated FPU and DSP on a 32-bit MIPS core (vs PIC32MZ1024ECM144-I/PH)
- Largest SRAM option in the 144-pin TQFP EF family (vs PIC32MZ1024EFF144-I/PH)
- Extended temperature drop-in upgrade path (vs PIC32MZ1024EFK144-E/PH)
Design Notes
The PIC32MZ EF core requires eight VDD/VSS pin pairs plus a 4.7 uF low-ESR capacitor on the VCAP pin (pin 103) for the internal 1.2 V regulator. Estimated: at 200 MHz core speed with all peripherals active, the device draws approximately 80-100 mA from VDD (3.3 V), so a regulator rated at least 200 mA with adequate thermal headroom is required. Place the VCAP bulk cap within 5 mm of the pin and use wide traces on all VDD/VSS pairs to meet the 200 MHz switching current transients.
Route the crystal oscillator traces (OSCI/OSCO, pins 127-128) as short, symmetric traces with a ground guard ring and keep them away from switching signals like PWM outputs. Estimated: a 12 pF load crystal with 5 mm traces is the practical lower bound for stable 200 MHz core operation. The 32.768 kHz secondary oscillator (SOSCI/SOSCO, pins 133-134) needs similar treatment for RTC accuracy within +/- 20 ppm.
Any PGECx/PGEDx pair (e.g. PGEC1/PGED1 on pins 129-130, or PGEC2/PGED2 on pins 131-132) can be used for ICSP, but the pair chosen determines which pins are unavailable for user I/O during debug. Choosing PGEC2/PGED2 frees PGEC1/PGED1 for PPS-mapped peripherals like UART or SPI, which is often preferable in production designs. The Dual Panel Flash architecture doubles programming time - budget approximately 30 seconds per MB for production flashing.
Compliance Information
RoHS and REACH compliant per Microchip product page. Not AEC-Q100 qualified - choose PIC32MZ1024EFK144-E/PH with extended temperature for automotive designs above 85C ambient. Industrial -40C to +85C operating range only.
