XC7A35T-1FGG484I Overview
An FPGA (Field Programmable Gate Array) is an integrated circuit that can be configured by the customer after manufacturing to implement any digital logic function. Unlike fixed-function ASICs, FPGAs contain programmable logic blocks, configurable I/O, and routing resources that allow designers to implement complex digital systems in hardware. The Artix-7 family sits between the low-cost Spartan-7 and the higher-performance Kintex-7 in AMD's 7-series portfolio, targeting applications where cost and power efficiency are paramount.
Key features of the XC7A35T-1FGG484I include 250 user I/O pins, 2,600 Configurable Logic Blocks (CLBs), 33,280 logic cells, and 1,843,200 total RAM bits. The device integrates five Clock Management Tiles (CMTs) with MMCM and PLL blocks for flexible clock generation, and supports multiple I/O standards including LVCMOS, LVDS, and HSTL. The 484-ball FBGA package provides a compact 23x23mm footprint with 0.8mm ball pitch, enabling dense PCB layouts.
The Artix-7 architecture is built on a 28nm high-k metal gate (HKMG) process technology, delivering up to 50% lower power consumption compared to previous generations. The device supports partial reconfiguration, allowing dynamic updates to logic functions without powering down the system. With support for AMD Vivado Design Suite, designers can implement complex designs using a mature and comprehensive toolchain.
Typical applications include industrial motor control, medical imaging, software-defined radio, video processing, and automotive driver assistance systems. The industrial temperature grade makes it suitable for harsh environments where reliability is critical.
When designing with this device, ensure adequate decoupling capacitors on all power rails and follow the PCB layout guidelines in UG475 for the 484-FBGA package to maintain signal integrity.

Design Notes
The XC7A35T-1FGG484I requires multiple power rails: VCCINT at 1.0V, VCCAUX at 1.8V, and VCCO for each I/O bank. Use dedicated power regulators with adequate decoupling. Place 100nF ceramic capacitors close to each power pin and 10uF bulk capacitors on each rail. Follow the power sequencing requirements in DS181 to avoid latch-up or damage.
The 484-FBGA package has a 0.8mm ball pitch, requiring careful PCB design. Use microvias or blind vias for routing. Ensure the thermal pad is connected to a solid ground plane for heat dissipation. Follow the layout guidelines in UG475 for the 484-FBGA package to maintain signal integrity and manufacturability.
Do not exceed the maximum input voltage on any I/O pin. Ensure all unused I/O pins are configured properly in the Vivado design to avoid floating inputs. When migrating between speed grades, re-verify timing closure as the -2 grade may require different constraints. Always check the device pinout file for the specific package before layout.
