AMD XC7VX690T-2FFG1158C

Overview

XC7VX690T-2FFG1158C from AMD is a high-performance 28 nm Virtex-7 FPGA with 693,120 logic cells, 3,648 DSP slices, and 48.8 Mb of block RAM. It features 1,158-pin flip-chip BGA packaging, supports transceivers up to 13.1 Gb/s, and is used in high-end radar signal processing systems requiring deterministic low-latency data flow.

For engineers reviewing the XC7VX690T-2FFG1158C datasheet, pinout, applications, or equivalent options, key selection criteria include transceiver lane count, I/O bank voltage flexibility, thermal performance under sustained 20 W dynamic power, and configuration interface compatibility with SPIx4 or SelectMAP.

Technical Context

The XC7VX690T-2FFG1158C implements a segmented architecture with 24 I/O banks supporting selectable VCCO (1.2–1.8 V), dedicated clock routing networks, and integrated PCI Express Gen3 x8 endpoint capability. Its CLB structure includes dual 6-input LUTs with carry chain and distributed RAM per slice.

Configuration occurs via master SPI or slave SelectMAP mode using 256-bit AES decryption; bitstream integrity is enforced by CRC checking on every configuration frame. The device supports partial reconfiguration through ICAP and includes hardened Ethernet MAC blocks for 10/100/1000BASE-T operation.

Key Specifications

Pinout & Package

FAQ

What is the maximum supported transceiver data rate for XC7VX690T-2FFG1158C?

The XC7VX690T-2FFG1158C supports GTY transceivers with a maximum data rate of 13.1 Gb/s per lane, validated per CPRI v7.0 and 10GBASE-R standards. This rate is achievable under specified junction temperature and power supply conditions, and requires proper PCB stackup with controlled impedance traces and matched length routing for differential pairs. The XC7VX690T-2FFG1158C includes built-in TX pre-emphasis and RX equalization to maintain signal integrity at this speed.

Does XC7VX690T-2FFG1158C support partial reconfiguration?

Yes, XC7VX690T-2FFG1158C supports runtime partial reconfiguration via the Internal Configuration Access Port (ICAP). This allows dynamic swapping of functional modules-such as different filter coefficients or protocol engines-without resetting the entire device or interrupting active I/O operations. The XC7VX690T-2FFG1158C requires bitstream partitioning during implementation and adherence to placement constraints defined in UG909 to ensure timing closure across reconfigurable regions.

What configuration modes does XC7VX690T-2FFG1158C support?

XC7VX690T-2FFG1158C supports four primary configuration modes selected by M0–M2 pins: Master SPI (default), Slave SPI, SelectMAP, and JTAG. It also supports fallback configuration from dual SPI flash and supports 256-bit AES encryption with HMAC authentication for secure bitstream loading. The XC7VX690T-2FFG1158C validates each configuration frame using CRC before committing to configuration memory.

Is XC7VX690T-2FFG1158C pin-compatible with other Virtex-7 devices?

No, XC7VX690T-2FFG1158C is not pin-compatible with other Virtex-7 devices due to its unique 1158-pin FFG package and I/O bank layout optimized for high-density transceiver and memory interface routing. While logic resources and configuration interfaces follow Virtex-7 architecture conventions, physical pin mapping differs significantly from smaller variants like XC7VX485T (FFG1157) or XC7VX330T (FFG1157). Board-level reuse requires package-specific layout verification.

What thermal management is required for XC7VX690T-2FFG1158C in continuous operation?

XC7VX690T-2FFG1158C has a typical thermal design power of 20.1 W under full utilization and requires active cooling: a minimum 25 CFM airflow over a 35 mm × 35 mm copper heatsink attached to its thermal lid. Junction temperature must remain below 100°C per UG475. The XC7VX690T-2FFG1158C includes on-die temperature sensors accessible via XADC for closed-loop thermal monitoring and throttling control.
