XC7A35T-2FGG484C 概要
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. FPGAs are part of the broader category of programmable logic devices, which also includes CPLDs. They are used in a wide range of applications where flexibility, parallel processing, and rapid prototyping are needed, from industrial motor control to communications infrastructure.
Key features of the XC7A35T-2FGG484C include 250 user I/Os, 33,280 logic cells, and 1,843,200 bits of block RAM. The -2 speed grade offers a balance between performance and power, making it suitable for many mid-range applications. The 484-ball FBGA package provides a good compromise between I/O count and board area, and is a popular choice for designs that need more I/Os than smaller packages but do not require the density of larger ones.
Technically, the Artix-7 family is optimized for the lowest power and cost at 28nm, delivering the highest performance/watt fabric and AMS integration. The device includes hardened memory controllers, DSP slices, and clock management tiles (MMCM and PLL) that support a wide range of system requirements. The 28nm process technology enables high logic density and low static power, which is critical for battery-powered and thermally constrained applications.
Typical applications for the XC7A35T-2FGG484C include industrial motor control, software-defined radio, medical imaging, and video processing. Its combination of logic capacity, I/O count, and cost-effectiveness makes it ideal for these and other high-volume, cost-sensitive designs.
When designing with this device, careful attention should be paid to power supply decoupling and the configuration interface. The FPGA requires multiple supply rails (VCCINT, VCCAUX, VCCO) and a configuration source (e.g., SPI flash) to boot. Proper decoupling and a clean power-up sequence are essential for reliable operation.

設計ノート
The XC7A35T-2FGG484C requires multiple supply rails: VCCINT (1.0V), VCCAUX (1.8V), and VCCO (varies by bank). Use a dedicated power management IC to sequence these rails properly. Place 100nF decoupling capacitors close to each power pin and a 10uF bulk capacitor per rail. Refer to the Artix-7 power supply design guidelines in UG933 for detailed recommendations.
For the 484-ball FBGA package, use a 4-layer or more PCB with a solid ground plane. Route high-speed signals with controlled impedance (e.g., 50 ohm single-ended, 100 ohm differential). Ensure the BGA fanout is done correctly, using via-in-pad if necessary. Follow the PCB design guidelines in UG483 for the FGG484 package.
A common pitfall is incorrect configuration. The FPGA requires a configuration source (e.g., SPI flash) and a configuration mode (e.g., Master SPI). Ensure the mode pins are set correctly and the bitstream is generated for the correct device. Also, verify that all VCCO banks are powered to the correct voltage for the I/O standard used.
