AMD XC7A15T-2FTG256I

Overview

XC7A15T-2FTG256I from AMD (formerly Xilinx) is a Artix-7 FPGA featuring 15,850 logic cells, 1.8V core voltage, -2 speed grade, and 256-pin FTBGA package. It integrates 96 DSP slices, 3.2 Mb of block RAM, and supports PCIe Gen2 x2 endpoint functionality in industrial temperature range (-40°C to +100°C).

For engineers reviewing the XC7A15T-2FTG256I datasheet, pinout, applications, or equivalent options, key selection factors include logic density, I/O count (170 user I/Os), transceiver capability (no built-in GTs), thermal performance in extended temperature operation, and compatibility with Vivado Design Suite v2023.1+.

Technical Context

The XC7A15T-2FTG256I implements a 28 nm HKMG process-based architecture with configurable logic blocks (CLBs), distributed RAM, shift registers, and dedicated carry chains. It supports SelectIO standards including LVCMOS, SSTL, HSTL, and differential signaling (LVDS, TMDS) across its 170 user I/O pins.

It includes dual 32-bit AXI interconnect infrastructure, clock management tiles (CMT) with PLL and MMCM, and integrated configuration interfaces (JTAG, SPI, BPI). No transceivers are present-this device belongs to the non-GT Artix-7 T-series.

FAQ

What is the maximum supported I/O standard voltage for XC7A15T-2FTG256I?

The XC7A15T-2FTG256I supports I/O voltages from 1.2 V to 3.3 V across its 170 user I/O pins, with bank-specific VCCO supplies. Each I/O bank can be independently configured for LVCMOS12, LVCMOS15, LVCMOS18, LVCMOS25, LVCMOS33, SSTL15, SSTL18, and HSTL_I standards. Configuration is done via IOSTANDARD attribute in XDC constraints.

Does XC7A15T-2FTG256I include built-in transceivers for high-speed serial communication?

No, XC7A15T-2FTG256I does not include GT (Gigabit Transceiver) blocks. It belongs to the Artix-7 T-series, which omits high-speed serial transceivers to reduce cost and power. For PCIe Gen2 x2 endpoint use, external PHY or alternative routing via GPIO-based protocols (e.g., Aurora over LVDS) is required. XC7A15T-2FTG256I relies on SelectIO for parallel or low-speed differential interfaces.

What configuration modes are supported by XC7A15T-2FTG256I?

XC7A15T-2FTG256I supports Master SPI, Slave Serial, Slave Parallel, and JTAG configuration modes. Mode selection is controlled by M0–M2 pins at power-up. SPI flash (x1/x2/x4) is most common for production; JTAG is used for debugging and programming. Configuration bitstream size is ~3.1 MB for full density utilization.

Is XC7A15T-2FTG256I qualified for automotive applications?

No, XC7A15T-2FTG256I is rated for industrial temperature range (–40°C to +100°C) and is not AEC-Q100 qualified. It lacks automotive-specific screening, failure rate reporting, or PPAP documentation. For automotive use, AMD recommends the XA Artix-7 family (e.g., XA7A15T), which undergoes additional qualification testing and offers extended reliability data.

What version of Vivado Design Suite is required for XC7A15T-2FTG256I development?

Vivado Design Suite 2018.2 or later is required to synthesize, implement, and program XC7A15T-2FTG256I. Full support for partial reconfiguration, IP integrator, and timing analysis is available from v2020.1 onward. Recommended versions are Vivado 2022.2 and 2023.1, which include updated device support files and optimized place-and-route algorithms for Artix-7 T-series devices.
