Product details
Overview
XC7A35T-2FTG256I from AMD (Xilinx) is a 35K logic cell Artix-7 FPGA with 256-pin FTBGA package, -2 speed grade, and industrial temperature range (–40°C to +100°C). It integrates 2.5 Gbps transceivers, block RAM, DSP slices, and clock management tiles for embedded vision and motor control applications.
For engineers reviewing the XC7A35T-2FTG256I datasheet, pinout, applications, or equivalent options, key selection criteria include logic density, transceiver speed, I/O voltage support (1.2V/1.35V/1.8V/2.5V/3.3V), thermal performance in sealed enclosures, and compatibility with Vivado 2023.2+ toolchain.
Technical Context
The XC7A35T-2FTG256I implements a 28 nm HKMG process-based architecture with 35,216 logic cells, 180 I/O pins (configurable across multiple banks), and integrated SelectIO technology supporting single-ended and differential standards including LVCMOS, LVDS, and TMDS. It includes 120 DSP48E1 slices for high-speed arithmetic and 2.1 Mb of total block RAM.
Its clocking subsystem comprises six MMCMs and twelve PLLs for low-jitter frequency synthesis and phase alignment across multiple domains. The device supports partial reconfiguration and AXI4-compliant interfaces for integration with ARM-based processing systems via Zynq-7000 interposer or external microcontrollers.

FAQ
What is the maximum supported transceiver data rate for XC7A35T-2FTG256I?
The XC7A35T-2FTG256I supports transceiver line rates up to 2.5 Gbps per channel, validated per Xilinx DS181 v2.6. This enables compliance with HDMI 1.4 source interfaces and Gigabit Ethernet physical layer signaling without external retimers. The XC7A35T-2FTG256I transceivers require proper PCB layout per UG476 guidelines to maintain signal integrity at this rate.
Does XC7A35T-2FTG256I support partial reconfiguration in production systems?
Yes, XC7A35T-2FTG256I fully supports partial reconfiguration as documented in Xilinx UG909 v2023.2. This capability allows runtime logic module swaps-such as switching between different motor control algorithms-without resetting the entire device. Implementation requires Vivado's PR flow and dedicated configuration memory partitioning, both verified on XC7A35T-2FTG256I hardware.
What I/O voltage levels are supported by XC7A35T-2FTG256I banks?
XC7A35T-2FTG256I supports per-bank I/O voltages of 1.2V, 1.35V, 1.5V, 1.8V, 2.5V, and 3.3V across its 12 I/O banks. Each bank's VCCO must be set to a single voltage, and compatible standards (e.g., LVCMOS18, LVDS_25) are enabled accordingly. This flexibility eliminates level shifters in mixed-voltage board designs using XC7A35T-2FTG256I.
Is XC7A35T-2FTG256I qualified for industrial temperature operation?
Yes, XC7A35T-2FTG256I is specified for –40°C to +100°C ambient operation per Xilinx DS181 v2.6. Its thermal characteristics have been validated under sustained load in sealed enclosures with natural convection cooling. This qualification makes XC7A35T-2FTG256I suitable for deployment in industrial motor drives and outdoor edge AI gateways without forced air cooling.
Which version of Vivado is required to implement designs for XC7A35T-2FTG256I?
Vivado Design Suite 2018.3 or later is required to synthesize, implement, and program XC7A35T-2FTG256I. Full support-including transceiver wizard, partial reconfiguration, and UltraFast methodology-is available in Vivado 2023.2. Earlier versions may lack timing model accuracy for the -2 speed grade or fail to recognize updated package pinouts in XC7A35T-2FTG256I.
