MA-AX3-35-1I-D8-R3

Overview

The Enclustra MA-AX3-35-1I-D8-R3 is a Mars AX3 FPGA module featuring the Xilinx XC7A35T-1CSG324I Artix-7 device in a CSG324 package. It integrates 256MB DDR3 SDRAM and 64MB Quad SPI Flash within a 30x67.6mm SO-DIMM form factor with 200 pins. The module supports industrial temperature ranges (-40°C to +85°C) and operates on a single 3.3V supply, generating internal voltages onboard. Key peripherals include a Gigabit Ethernet PHY, a 50MHz oscillator, and an optional Real-Time Clock.

Feature Summary

• Xilinx Artix-7 XC7A35T-1CSG324I FPGA with 108 user I/Os supporting up to 3.3V
• Integrated 256MB DDR3 SDRAM and 64MB Quad SPI Flash for configuration and storage
• Gigabit Ethernet PHY connectivity via RJ45 connector
• SO-DIMM (200-pin) form factor compatible with Mars base boards

Applications

• High-speed communication systems
• Digital signal processing (DSP) applications
• Embedded processing system prototypes

Procurement Notes

Verify the article number EN101295 corresponds to the specific hardware revision R3. Confirm that the target base board utilizes a 200-pin DDR2 SO-DIMM socket rated for 1.8V to ensure mechanical and electrical compatibility. Ensure the design accounts for Class A electromagnetic compatibility requirements as defined by IEC 61000-3-2.

Selection Notes

Select this module when an industrial temperature range (-40°C to +85°C) is required alongside the Artix-7 35T logic capacity. The -1 speed grade indicates specific timing characteristics suitable for standard frequency operations. Verify that the 108 available user I/Os meet the interface requirements, noting that banks 34 and 35 support configurable VCC_IO voltages between 1.2V and 3.3V.

Part Context

This part belongs to the Mars AX3 FPGA module family from Enclustra. It shares the same physical footprint and peripheral integration strategy as other variants like the MA-AX3-50 and MA-AX3-100, differing primarily in the FPGA logic density and speed grade. The R3 suffix denotes a specific hardware revision documented in the Known Issues and Changes guide.

Replacement Considerations

Direct replacements within the Mars AX3 family include MA-AX3-50-1I-D8-R3 (XC7A50T) or MA-AX3-100-2I-D8-R3 (XC7A100T). These offer higher logic resources but maintain identical mechanical and pinout specifications.
