FAQ

What is the maximum supported DDR3 memory speed for XC7A100T-1FG484C?

The XC7A100T-1FG484C supports DDR3 and DDR3L memory interfaces up to 800 MHz data rate (1600 MT/s), implemented using its dedicated memory controller and PHY with on-die termination and write-leveling calibration. This capability is verified in Xilinx UG473 and applies directly to the XC7A100T-1FG484C in its default configuration mode.

Does XC7A100T-1FG484C include built-in PCIe Gen2 endpoint functionality?

Yes, XC7A100T-1FG484C integrates a hardened PCIe Gen2 x4 endpoint block compliant with PCI Express Base Specification v2.1. This includes physical layer, data link layer, and transaction layer logic, enabling direct connection to host systems without external bridge chips. Configuration is handled through standard AXI4-Lite registers.

What configuration modes does XC7A100T-1FG484C support?

XC7A100T-1FG484C supports Master SPI, Slave SelectMAP, and JTAG configuration modes. Master SPI uses an internal oscillator and external serial flash; Slave SelectMAP allows parallel loading from microcontroller or processor; JTAG enables boundary-scan testing and programming. All modes support AES-256 bitstream encryption.

Is partial reconfiguration supported on XC7A100T-1FG484C?

Yes, XC7A100T-1FG484C supports partial reconfiguration through Vivado Design Suite, allowing dynamic replacement of logical modules while the rest of the design remains operational. This feature is validated for Kintex-7 devices and used in applications such as adaptive filtering and protocol switching where runtime flexibility is required.

What is the I/O voltage range supported by XC7A100T-1FG484C banks?

XC7A100T-1FG484C supports I/O standards across 14 banks with VCCO ranging from 1.2 V to 3.3 V per bank. High-Range (HR) banks support LVCMOS, SSTL, and HSTL; High-Performance (HP) banks support LVDS and differential signaling. Each bank's voltage is independently configurable to match attached peripherals.
