Product details
Overview
XC7A35T-1CSG324I from AMD (formerly Xilinx) is a Artix-7 FPGA featuring 33,280 logic cells, 2.55 Mb of block RAM, 180 DSP slices, and supports -1 speed grade (1.0 ns CLB delay) in a 324-pin CSG package. It targets cost-sensitive high-performance applications including motor control, video processing, and industrial Ethernet gateways.
For engineers reviewing the XC7A35T-1CSG324I datasheet, pinout, applications, or equivalent options, key selection criteria include I/O count (210 user I/Os), transceiver support (no GT transceivers), single-ended LVCMOS/LVDS I/O standards, and industrial temperature range (-40°C to +100°C).
Technical Context
The XC7A35T-1CSG324I implements a 28 nm HKMG process-based architecture with configurable logic blocks (CLBs), distributed RAM, shift registers, and dedicated carry chains. It integrates SelectIO technology supporting 1.2 V to 3.3 V I/O standards and includes clock management tiles with MMCM and PLL for multi-phase clock synthesis.
No integrated transceivers are present; high-speed serial connectivity requires external PHYs. Configuration is performed via JTAG, SPIx4, or BPI parallel interfaces, with bitstream encryption and SEU mitigation features enabled in this industrial-grade variant.

FAQ
What is the maximum supported I/O standard voltage for XC7A35T-1CSG324I?
XC7A35T-1CSG324I supports I/O standards from 1.2 V to 3.3 V per bank via its SelectIO technology. Each of the 12 I/O banks has independent VCCO supply, enabling mixed-voltage operation - for example, interfacing with both 1.8 V sensors and 3.3 V microcontrollers simultaneously without level shifters. This capability is documented in the Artix-7 Data Sheet (DS181).
Does XC7A35T-1CSG324I include built-in high-speed transceivers?
No, XC7A35T-1CSG324I does not integrate GT (Gigabit Transceiver) blocks. It belongs to the non-transceiver Artix-7 variant. High-speed serial protocols such as PCIe, SATA, or SGMII require external PHY devices or alternative FPGA families like Kintex-7. This limitation is explicitly stated in the XC7A35T product selection guide and pinout documentation.
What configuration modes are supported by XC7A35T-1CSG324I?
XC7A35T-1CSG324I supports JTAG, master SPI (x1/x2/x4), and slave parallel (BPI) configuration modes. The device boots from external flash via SPIx4 by default but can be reconfigured dynamically using ICAP port. Configuration security features include AES bitstream encryption and HMAC authentication, both enabled in the industrial-grade XC7A35T-1CSG324I variant.
Is XC7A35T-1CSG324I pin-compatible with other Artix-7 devices in CSG324 package?
XC7A35T-1CSG324I shares the same CSG324 footprint and pinout with XC7A50T-1CSG324I and XC7A75T-1CSG324I, enabling direct PCB replacement within the same speed grade. However, unused pins may differ in function assignment, and configuration pin behavior remains consistent across these variants per UG470.
What is the total amount of block RAM available in XC7A35T-1CSG324I?
XC7A35T-1CSG324I provides 2.55 Mb of total block RAM, implemented across 135 BRAM primitives. Each BRAM can be configured as 36 Kb dual-port RAM, 18 Kb single-port RAM, or 72 Kb shift register. This resource is fully accessible to HDL logic and supported by Vivado synthesis tools for inference or explicit instantiation in the XC7A35T-1CSG324I design flow.
