AMD XC7VX485T-2FFG1930I

Overview

XC7VX485T-2FFG1930I from AMD is a high-performance 28 nm Virtex-7 FPGA with 485,760 logic cells, 2,825 DSP slices, and 36.4 Mb of block RAM; supports PCIe Gen3 x8, DDR3-1866 memory interface, and operates at -2 speed grade with industrial temperature range (-40°C to +100°C) in demanding radar signal processing systems.

For engineers reviewing the XC7VX485T-2FFG1930I datasheet, pinout, applications, or equivalent options, key selection factors include validated I/O bank voltage support (1.2 V/1.35 V/1.5 V/1.8 V), transceiver line rates up to 13.1 Gb/s, and configuration via Master SPI or JTAG with AES bitstream encryption.

Technical Context

The XC7VX485T-2FFG1930I implements a 28 nm HKMG process-based architecture with configurable logic blocks (CLBs), 36-Kb block RAMs, and multi-gigabit transceivers (MGTs) supporting protocols including CPRI, SRIO, and 10G Ethernet. It integrates hardened IP for PCIe Gen3, memory controllers, and clock management tiles with MMCM and PLL.

Configuration is performed through dedicated configuration pins (INIT_B, PROGRAM_B, CCLK, DIN) using either slave serial, master SPI, or JTAG modes; bitstream security includes AES-256 decryption and HMAC authentication to prevent unauthorized programming.

FAQ

What is the maximum supported DDR3 memory speed for XC7VX485T-2FFG1930I?

The XC7VX485T-2FFG1930I supports DDR3-1866 (933 MHz) operation with a hardened memory controller that handles address/command timing, write leveling, and read-leveling calibration. This capability allows direct connection to standard DDR3 SO-DIMMs without external PHY, reducing BOM cost and board area in high-throughput data buffering applications involving the XC7VX485T-2FFG1930I.

Does XC7VX485T-2FFG1930I support partial reconfiguration?

Yes, the XC7VX485T-2FFG1930I fully supports partial reconfiguration through its ICAP and PCIe-based configuration access port. This enables dynamic swapping of functional modules-such as different filter banks or modulation schemes-without resetting the entire device or halting active I/O operations, a key capability for mission-critical systems deploying the XC7VX485T-2FFG1930I in field-upgradable radar or comms platforms.

What transceiver protocols are natively supported by XC7VX485T-2FFG1930I?

The XC7VX485T-2FFG1930I includes 32 multi-gigabit transceivers supporting native protocols including PCIe Gen3, CPRI (up to Option 10), SRIO Gen2, and 10GBASE-R. These are implemented in hardened logic with deterministic latency and guaranteed jitter performance, eliminating the need for custom SerDes design when integrating the XC7VX485T-2FFG1930I into high-speed serial interconnect applications.

What configuration security features does XC7VX485T-2FFG1930I provide?

The XC7VX485T-2FFG1930I provides AES-256 bitstream encryption and HMAC-SHA256 authentication to protect against reverse engineering and unauthorized programming. These features are enforced during every configuration cycle and require valid keys stored in on-chip eFUSE or external secure memory, ensuring only authorized firmware loads onto the XC7VX485T-2FFG1930I in deployed systems.

Is XC7VX485T-2FFG1930I pin-compatible with other Virtex-7 FPGAs in the FFG1930 package?

XC7VX485T-2FFG1930I shares the same 1930-ball FFG package footprint and I/O bank arrangement with XC7VX690T-2FFG1930I, enabling mechanical and thermal compatibility. However, not all pins have identical functionality-some configuration and transceiver pins differ-and full pin-to-pin compatibility requires verification against the specific device's pinout table before board reuse.
