1. Product Overview
The XC5VLX30-1FFG676C is a mid-range, high-performance FPGA from the Xilinx Virtex-5 LX series. Manufactured using 65nm CMOS technology and based on the second-generation ASMBL (Advanced Silicon Modular Block) architecture, this device targets general-purpose high-performance logic applications. It is well-suited for systems requiring moderate logic density and a high number of user I/Os, such as control logic, interface bridging, and signal processing subsystems.

3. Architectural Highlights
(1) Efficient LUT-Based Logic
Built on true 6-input LUT architecture, the XC5VLX30 supports a dual 5-LUT output mode, enhancing routing flexibility and logic efficiency. LUTs are multifunctional and can serve as distributed synchronous RAM or shift registers, supporting resource reuse in compact designs.
(2) Configurable On-Chip Memory
The device integrates multiple 36-Kbit Block RAMs with true dual-port operation, optional ECC, byte-write capability, and FIFO control logic, ideal for implementing data buffers, temporary storage, or caching schemes.
(3) Advanced Clock Management
Supports up to two Clock Management Tiles (CMTs), each consisting of two DCMs and one PLL. These enable frequency synthesis, phase adjustment, and input jitter filtering, making the device suitable for timing-critical applications.
(4) Flexible I/O Interface Support
The FPGA supports a wide range of I/O standards, including LVTTL, LVCMOS, HSTL, SSTL, and LVDS. It also integrates ChipSync™ source-synchronous interfacing and per-bit deskew capability, making it ideal for DDR memory, ADC interfaces, and other timing-sensitive signal interfaces.
4. Packaging and I/O Resources
The XC5VLX30-1FFG676C comes in a Fine-Pitch BGA676 (FFG676) package with a compact 27mm × 27mm footprint. It supports up to 400 user I/Os, offering a good balance between I/O density and board routing flexibility, making it well-suited for I/O-intensive or space-constrained system designs.
5. Typical Application Scenarios
The XC5VLX30-1FFG676C is especially well-suited for mid- to high-complexity applications such as:
- Multi-axis motion controllers and industrial automation control boards
- General-purpose interface bridges (e.g., SPI/UART ↔ GPIO)
- Video pre-processing tasks (e.g., pixel shifting, filtering)
- Embedded control logic with moderate logic resource requirements
- Reconfigurable I/O expansion modules or on-board test subsystems
