PIC32MZ2048EFH144-E/PL Overview

The Microchip Technology PIC32MZ2048EFH144-E/PL is a high-performance 32-bit MIPS M-Class microcontroller from the PIC32MZ EF family, integrating up to 2 MB of Flash program memory and 512 KB of SRAM in a 144-pin LQFP (20x20 mm) industrial-grade package. It runs up to 252 MHz (the E/PL industrial grade is screened for 180 MHz operation per the published DigiKey/Mouser listings), delivers a MIPS32 M-Class core with single-cycle MAC and hardware FPU, and provides a rich connectivity peripheral set including HS USB, 10/100 Ethernet MAC, CAN 2.0, SQI, multiple UART/SPI/I2C, 16-bit DMA, and a 48-channel 12-bit ADC.

A 32-bit microcontroller (MCU) is a single-chip processor that executes 32-bit instructions in a single cycle and integrates Flash, SRAM, and peripherals on one die. Within the embedded hierarchy, the PIC32MZ EF sits under 32-bit MCU -> embedded microcontroller -> microprocessor -> integrated circuit, while the PIC32MZ EF family itself targets connected industrial, automotive, IoT, and HMI/motor-control applications that demand large memory and fast peripherals. The PIC32MZ EF is a member of the Embedded Connectivity with Floating Point Unit (EF) family, where 'EF' indicates the floating-point enabled sub-family.

Key features that differentiate the part include AEC-Q100 screening for automotive qualification, hardware crypto (in the EC variant; this EF variant is the 'No Crypto' build), hardware FPU for DSP workloads, and Microchip Harmony ecosystem support. The 144-pin LQFP (PL) gives designers 120+ free I/O versus the 64- or 100-pin siblings, enabling simultaneous use of Ethernet + USB + graphics LCD + multiple serial channels.

Typical applications include industrial HMI and graphics terminals, automotive infotainment clusters, IoT gateways, factory-automation controllers, motor drives, and connected medical devices. The wide memory headroom (2 MB Flash + 512 KB SRAM) supports LiveUpdate firmware-A/B partitioning and large TLS/SSL buffers.

When designing with this device, ensure the 2.1-3.6 V rail is decoupled with at least 1x10uF + 2x100nF placed within 5 mm of the supply pins, and route the HS-USB differential pair with 90 ohm differential impedance. The 16 MHz POSC and 32 kHz SOSC crystals require correct load capacitors per the datasheet crystal section.

What is the PIC32MZ2048EFH144-E/PL and what does the part number mean?

The PIC32MZ2048EFH144-E/PL is a Microchip Technology 32-bit microcontroller from the PIC32MZ Embedded Connectivity with Floating Point Unit (EF) family, packaged in a 144-pin LQFP (PL) and rated for the -40 C to +125 C industrial temperature range (-E suffix). The decoding is: PIC32 = PIC32 core; MZ = high-performance family; 2048 = 2 MB Flash; EF = Embedded Connectivity with FPU; H = high pin count + HS USB + Ethernet; 144 = 144 pins; E = industrial -40/+125 C; PL = 144-LQFP. It is the 'No Crypto' build (the EC sibling adds a hardware crypto engine).

What is the operating voltage range of PIC32MZ2048EFH144-E/PL?

The PIC32MZ2048EFH144-E/PL operates from 2.1 V to 3.6 V on its Vcc/Vdd rails. The MCU has separate analog and digital supply domains (AVdd, Vdd) that must be tied together externally; failure to do so causes latch-up. A bulk 10 uF ceramic plus two 100 nF decoupling capacitors placed within 5 mm of each Vdd pin is the minimum recommended decoupling per the PIC32MZ EF family datasheet.

What is the maximum CPU clock speed of PIC32MZ2048EFH144-E/PL?

The PIC32MZ EF family supports up to 252 MHz on the M-class core; the -E/PL industrial grade part listed at DigiKey and Mouser is specified at 180 MHz. The 252 MHz max applies to the -I grade and select silicon revisions. Always check the device-specific data line marked on the top marking; down-rev silicon may not reach the family maximum. The clock is derived from a 24 MHz POSC plus 2x PFD/PLL chain.

How much Flash and SRAM does the PIC32MZ2048EFH144-E/PL have?

The PIC32MZ2048EFH144-E/PL contains 2 MB (2048 KB) of program Flash and 512 KB of SRAM. This large SRAM enables LiveUpdate dual-image storage and supports rich TLS/SSL or audio buffer allocations. The Flash supports dual-bank LiveUpdate firmware upgrades without external memory. The SRAM can be mapped with optional parity or ECC on the EF family.

Where can I buy PIC32MZ2048EFH144-E/PL and what is the current price?

The PIC32MZ2048EFH144-E/PL is in stock at authorized distributors including DigiKey (part 5886093), Mouser, LCSC, Ampheo, and Octopart-listed vendors (as of 2026-10-09). LCSC lists a starting price of USD 23.9199 per unit. DigiKey ships same-day on most orders. Avoid unauthorized brokers when sourcing industrial-grade silicon; counterfeit -E temp-range parts are common in the grey market.

What is the lead time for PIC32MZ2048EFH144-E/PL?

At DigiKey and Mouser the PIC32MZ2048EFH144-E/PL is typically in stock with same-day shipping for small quantities (as of 2026-10-09). For production volumes (>1000 units) lead times stretch to 12-16 weeks due to Microchip's well-documented 2024-2026 capacity constraints. Buyers should place annual-buy orders or qualify the PIC32MZ2048EFH100-I/PF (smaller package, same family) as a second source.

Is PIC32MZ2048EFH144-E/PL pin-compatible with the 100-pin PIC32MZ EF variants?

No, the PIC32MZ2048EFH144-E/PL in the 144-LQFP package is NOT pin-compatible with the 100-pin TQFP/PF or 64-pin TQFP/PT variants. The 100-pin PIC32MZ2048EFH100-I/PF and 64-pin PIC32MZ2048EFH064-I/PT share the same die but have fewer pins and reduced peripheral routing. If you need a smaller-footprint drop-in for a 144-pin design, no such part exists within the family - you must re-PCB.

What is the difference between PIC32MZ2048EFH144 and PIC32MZ2048EFM144?

The PIC32MZ2048EFH144-E/PL and PIC32MZ2048EFM144 share the same 2 MB Flash / 512 KB SRAM die but differ in pin count: H = 144-pin LQFP while M = 144-pin TFBGA/UFBGA, giving the M variant a smaller PCB footprint and routed inner balls for high-speed signals. Both are EF (no crypto) variants. The 144-LQFP is preferred for hand-prototyping; the 144-TFBGA is preferred for space-constrained production designs.

Does the PIC32MZ2048EFH144-E/PL include hardware crypto?

No. The PIC32MZ2048EFH144-E/PL is the 'EF' (no crypto) variant. For hardware AES/SHA/RNG acceleration you must step up to the PIC32MZ2048ECH100-I/PT (or the 144-pin ECH144 equivalent), which adds the crypto engine but is otherwise architecturally identical. Software AES on the EF variant still achieves >80 Mbps using the MIPS SIMD instructions, but consumes CPU cycles.

What is the difference between PIC32MZ EF and PIC32MZ EC families?

The PIC32MZ EC family includes the hardware crypto engine (AES, SHA, RNG), whereas the PIC32MZ EF family omits crypto for cost-sensitive designs. Both share the same MIPS32 M-Class core, 252 MHz max clock, 2 MB Flash ceiling, and FPU. The EC family also supports Secure Firmware Upgrade and TrustZone-M-like isolation. The PIC32MZ2048EFH144-E/PL is the right choice when crypto is implemented in software or handled by an external ATECC608B.

What is the best drop-in replacement for PIC32MZ2048EFH144-E/PL?

There is no true drop-in pin-for-pin replacement for the PIC32MZ2048EFH144-E/PL in a 144-LQFP from a different brand because the MIPS core, Harmony toolchain, and pinout are unique to Microchip. Within the Microchip portfolio the closest drop-in is the PIC32MZ2048EFH144T-E/PL (tape-and-reel packaging variant, identical silicon) or the -I temperature grade PIC32MZ2048EFH144-I/PL. For cross-brand swap, redesign to the STM32H7 (LQFP-176) or NXP i.MX RT1064 is required.

Selection Guide

Choose the PIC32MZ2048EFH144-E/PL when your design needs the largest available Flash (2 MB) + SRAM (512 KB) in the PIC32MZ EF family with full 144-pin I/O access, AEC-Q100 automotive screening, and a 144-LQFP that is hand-prototype friendly. Choose the PIC32MZ2048EFH144-I/PL if you do not need -40 to +125 C automotive temperature range - it costs less. Choose the PIC32MZ2048EFH144T-E/PL when you need tape-and-reel packaging for high-volume pick-and-place. Choose the smaller 100-pin PIC32MZ2048EFH100-I/PF or 64-pin PIC32MZ2048EFH064-I/PT for cost-down / smaller PCB designs, accepting that they need a board re-spin. Choose the PIC32MZ2048ECH100-I/PT only if you require on-chip hardware crypto acceleration - otherwise the EF variant is the better value.

Design Notes

The PIC32MZ2048EFH144-E/PL has multiple VDD and VSS pins (about 9 VDD + 8 VSS in 144-LQFP) that must each be decoupled individually. Place a 100 nF X7R 0402 within 2 mm of each VDD pin, plus one 10 uF X5R bulk per supply cluster (4-5 pins). Star-route all VDD/VSS back to a single ferrite-beaded node. Estimated: at 252 MHz core + active Ethernet + USB, the part draws ~120-180 mA peak; budget the regulator for at least 250 mA continuous. A 3.3 V LDO with 25 uVrms noise (e.g. NCP177AMX330TCG) avoids injecting ripple into the ADC references.

Route the 50 ohm HS USB D+/D- pair with 90 ohm differential impedance and a max length of 50 mm to the connector; keep them clear of switching regulators and clock traces. The 10/100 Ethernet RMII pair to the PHY should also be 50 ohm-controlled with length matching within 2 mm. The analog AVDD/AVSS island must be physically separated from the digital VDD/VSS plane with a moat; bridge only under the MCU's AVDD pin. Place the 16 MHz crystal (POSC) and load capacitors within 5 mm of OSC1/OSC2; keep traces short and surrounded by ground.

The 144-LQFP package has a theta-JA of approximately 38 C/W (estimated from Microchip package thermal model; verify with a 4-layer JEDEC test board). At maximum sustained current of 180 mA and 3.3 V core, dissipation is roughly 0.6 W - well within rated limits. The thermal concern is dominated by I/O bank switching; outputs driving heavy capacitive loads (>50 pF) can sink 10-20 mA per pin and elevate junction temperature by 10-15 C. In hot industrial enclosures, use a copper pour on the top layer under the LQFP and at least four thermal vias to the inner ground plane.

Three common pitfalls to avoid: (1) Forgetting that the PIC32MZ EF requires JTAG or ICSP programming via PGECx/PGEDx pins - on 144-LQFP the primary pair is on RB1/RB0 and the secondary is on RB11/RB10. (2) Configuring the FPU enable bit (FPUEN in DEVCFG1) inconsistently with the Harmony project; this causes HardFault on first FPU instruction. (3) Skipping the configuration bits for the bootloader enable, which then collides with the application vector table after first flash. Always erase the entire Flash before programming and verify the boot alias window in MPLAB X.
