PIC32MZ1024EFM144-I/PL - 200MHz 1MB Flash MCU w/ FPU | Microchip
MPN： PIC32MZ1024EFM144-I/PL ✓ 啟用中PIC32MZ1024EFM144-I/PL 概覽
A 32-bit microcontroller (MCU) is a microprocessor with on-chip Flash program memory, RAM, peripherals, and interrupt controllers integrated into a single IC. Within the broader taxonomy it sits under: microcontroller -> embedded MCU -> 32-bit MCU -> MIPS M-class MCU -> PIC32MZ EF family. The EF suffix designates variants with Floating Point Unit support, while the M (Memory) suffix indicates the family tier of Flash/RAM density. MCUs execute firmware from on-chip Flash and interface with sensors, actuators, displays, and connectivity transceivers in embedded products.
Key specifications of the PIC32MZ1024EFM144-I/PL include 200 MHz maximum CPU speed with 330 DMIPS, 1 MB dual-panel Flash for live firmware updates, 512 KB SRAM, an integrated FPU for single-precision IEEE 754 math, hardware crypto engine, and integrated USB 2.0 High-Speed OTG plus 10/100 Ethernet MAC. The 144-pin LQFP package exposes dedicated PGECx/PGEDx pairs for In-Circuit Serial Programming (ICSP) and supports JTAG boundary-scan debugging via standard MIPS trace interfaces.
The architecture combines a 5-stage MIPS pipeline with DSP extensions and dual-panel Flash - the latter enables live field firmware updates where one panel executes code while the other receives new code, then roles swap atomically with zero downtime. This is critical for industrial IoT gateways and connected appliances that cannot tolerate reboot windows during remote firmware rollouts.
Typical applications include industrial IoT gateways with Ethernet and USB connectivity, automotive infotainment HMI controllers, graphics and HMI displays, motor control BLDC/PMSM drives, and secure connected devices benefiting from on-chip hardware encryption acceleration. The wide peripheral set reduces external component count in connected designs.
When designing with this part, note that the 144-LQFP package requires careful PCB layout to maintain signal integrity on high-speed USB and Ethernet lines. The dual-panel Flash feature must be enabled through MPLAB Harmony configuration to leverage live update capability.

主要差異化特點
- Highest CPU frequency in the PIC32MZ EF family at this temp grade (對比PIC32MZ1024EFM144-E/PL)
- Standard industrial temp grade matches common enclosure environments (對比PIC32MZ1024EFM144-E/PL)
- Tray packaging supports low-volume prototyping (對比PIC32MZ1024EFM144T-I/PL)
設計說明
Estimated: the PIC32MZ1024EFM144-I/PL core draws ~150 mA at 200 MHz from the 1.2 V internal regulator, with I/O draw depending on output loading. Per Microchip datasheet, the on-chip 3.3 V-to-1.2 V LDO must have at least 10 uF of bulk decoupling plus 100 nF of high-frequency bypass on VDD/VSS pins. Place bulk caps within 5 mm of the LDO input/output pins. Use a star-ground topology to isolate analog AVSS if ADC accuracy is required.
Route USB D+/D- as a 90-ohm differential pair with reference to digital ground, length-matched within 150 mil per the USB 2.0 High-Speed specification. The Ethernet RMII/MII traces to the external PHY must be length-matched and routed over a continuous ground plane. Place the 25 MHz main crystal within 5 mm of OSC1/OSC2 with short traces and a guard ground ring; use 12 pF load capacitors as specified in the datasheet.
Estimated: at full 200 MHz operation the PIC32MZ1024EFM144-I/PL draws ~300 mA total from the 3.3 V rail, dissipating roughly 1 W. The 144-LQFP theta_JA is approximately 35 C/W, yielding a 35 C junction rise above ambient - manageable for industrial designs. For closed enclosures, ensure at least 1 sq inch of top-side copper pour under the exposed pad-style center footprint pattern. Drop to PIC32MZ1024EFM144-E/PL only if junction temperature remains below 125 C at worst-case ambient.
Do not leave unused pins floating - configure them as outputs or inputs with the internal pull-up enabled per the Microchip datasheet, otherwise floating inputs cause spurious current draw and noise. When using dual-panel Flash live updates, follow the Microchip application note AN1388 for bank-swapping sequences - failing to disable interrupts during panel swap can corrupt firmware state. The integrated FPU must be enabled in MPLAB XC32 compiler with -mfloat-abi=hard to leverage hardware acceleration.
