AMD XC7A75T-2FT256I

Overview

XC7A75T-2FT256I from AMD is a 7-series Artix-7 FPGA with 74,919 logic cells, 3.15 Mb of block RAM, and 240 DSP slices, configured in a 256-pin FTBGA package with -2 speed grade and industrial temperature range (-40°C to +100°C). It serves as a reconfigurable fabric for high-throughput digital signal processing in compact embedded vision systems.

For engineers reviewing the XC7A75T-2FT256I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (170 user I/Os), transceiver capability (no integrated multi-gigabit transceivers), configuration interface (SPIx4/JTAG), and thermal design implications of the 10×10 mm FTBGA package.

Technical Context

The XC7A75T-2FT256I implements a synchronous, SRAM-based programmable logic architecture with configurable logic blocks (CLBs), distributed RAM, shift registers, and dedicated carry chains. It supports SelectIO standards including LVCMOS, LVDS, SSTL, and HSTL across its 170 user I/O pins.

Configuration is performed via Master SPI or JTAG, with bitstream security enabled through AES-256 encryption and HMAC authentication. The device lacks built-in PCI Express® or Gigabit Ethernet MAC blocks, requiring external PHY or soft IP implementation for those protocols.

Key Specifications

Pinout & Package

The XC7A75T-2FT256I is housed in a 256-ball Fine-Pitch Thin BGA (FTBGA) package with 170 user-configurable I/Os, 12 configuration pins (including INIT_B, PROGRAM_B, CCLK, D0–D3, M0–M2), and dedicated power/ground balls distributed per Xilinx UG475 v1.13.

FAQ

What is the maximum supported I/O standard voltage for XC7A75T-2FT256I?

The XC7A75T-2FT256I supports I/O standards from 1.2 V to 3.3 V across independent banks, with each bank configurable for LVCMOS, LVDS, SSTL, or HSTL signaling. Voltage tolerance is strictly per bank-no single I/O pin supports all voltages simultaneously-and VCCO must match the selected standard's specification as defined in Xilinx DS181 Table 13.

Does XC7A75T-2FT256I include built-in multi-gigabit transceivers?

No, the XC7A75T-2FT256I does not integrate multi-gigabit transceivers. It relies on external PHY devices or FPGA-based soft IP for high-speed serial interfaces such as PCIe, SATA, or 10GbE. This distinguishes it from Kintex-7 or Virtex-7 families, which include GTX/GTH transceivers.

Can XC7A75T-2FT256I be configured using JTAG only, without SPI?

Yes, XC7A75T-2FT256I supports JTAG configuration as a primary method via TCK/TMS/TDI/TDO pins, enabling programming, debugging, and boundary-scan testing. However, JTAG cannot load encrypted bitstreams-AES-256 encryption requires Master SPI or BPI configuration mode for secure deployment.

What thermal management considerations apply to XC7A75T-2FT256I in industrial environments?

XC7A75T-2FT256I operates from –40°C to +100°C junction temperature. In sealed enclosures above 70°C ambient, a minimum 2-layer PCB with thermal vias under the package and copper pour on inner layers is recommended. Thermal resistance θJA is 25.2°C/W (JEDEC Std 51-7, 4-layer board), requiring active airflow or heatspreading for sustained >3 W dynamic power.

Is XC7A75T-2FT256I compatible with Vivado Design Suite 2023.2?

Yes, XC7A75T-2FT256I is fully supported in Vivado Design Suite 2023.2, including synthesis, implementation, simulation, and bitstream generation. Device files, IP integrator templates, and hardware manager recognition are included out-of-the-box; no additional patches or legacy ISE migration steps are required.
