AMD HW-V4-ML402-UNI-G

Overview

HW-V4-ML402-UNI-G is a Xilinx ML402 evaluation platform designed for rapid prototyping and validation of Virtex-4 SX-series FPGA designs. It integrates an XC4VSX35-FF668-10 FPGA, 64-MB DDR SDRAM (32-bit/266 MHz), 140-MHz 24-bit VGA video DAC, tri-speed Ethernet PHY, USB host/peripheral interface (Cypress CY7C67300), and AC97 audio codec - enabling full-system hardware-software co-development for embedded computing and high-performance digital logic applications.

For engineers reviewing the HW-V4-ML402-UNI-G datasheet, pinout, applications, or equivalent options, this page delivers verified board-level specifications, configuration options (JTAG, Platform Flash, System ACE CompactFlash), expansion header I/O mapping (J5/J6), and FPGA bank voltage/DCI support details essential for FPGA-based system integration and IP validation.

Technical Context

The HW-V4-ML402-UNI-G implements a complete Virtex-4 development environment with dual differential clock I/O via SMA connectors (SMA_DIFF_CLK_IN_P/N and SMA_DIFF_CLK_OUT_P/N), configurable FPGA I/O banks (10 used, Bank 7 user-selectable between 2.5V/3.3V), and on-board power regulation including TPS54310 (3A), TPS54610 (6A), and TPS51100 (3A DDR LDO). It supports all Virtex-4 configuration modes: JTAG, Master/Slave Serial, and Master/Slave SelectMAP.

Hardware peripherals include stereo AC97 audio (line-in/out, mic-in, 50-mW headphone), RS-232 serial port, PS/2 keyboard/mouse interfaces, 16×2 LCD, 4-Kb I²C EEPROM, ZBT SRAM (9 Mb, 32-bit + 4 parity), and Intel StrataFlash (8 MB) - all directly interfaced to the XC4VSX35 FPGA without external glue logic.

FAQ

What FPGA is installed on the HW-V4-ML402-UNI-G evaluation board?

The HW-V4-ML402-UNI-G features the Xilinx XC4VSX35-FF668-10 FPGA - a Virtex-4 SX-series device with 34,560 logic cells, 172 DSP48 slices, 2.5 Mb of block RAM, and 320 user I/Os in a 668-pin flip-chip BGA package. This FPGA targets high-performance embedded processing and digital signal applications, and is pre-soldered and fully functional on the HW-V4-ML402-UNI-G board.

Does the HW-V4-ML402-UNI-G support VGA output, and what are its capabilities?

Yes, the HW-V4-ML402-UNI-G supports VGA output via a dedicated 140-MHz, 24-bit video DAC. It enables real-time display generation at resolutions up to XGA (1024×768) with programmable timing controlled by the XC4VSX35 FPGA. The DAC connects directly to the FPGA's I/O banks, allowing pixel-clock synchronization and custom video pipeline implementation without external timing controllers.

What configuration methods does the HW-V4-ML402-UNI-G support for the onboard FPGA?

The HW-V4-ML402-UNI-G supports five FPGA configuration modes: JTAG (using Parallel Cable IV), Master Serial, Slave Serial, Master SelectMAP, and Slave SelectMAP. Configuration storage options include the XCF32P Platform Flash, System ACE CompactFlash card (Type I/II), and CPLD-managed linear flash chips - all accessible via physical switches and jumpers on the board for flexible development workflows.

Can the HW-V4-ML402-UNI-G be used for high-speed differential I/O prototyping?

Yes, the HW-V4-ML402-UNI-G provides robust high-speed differential I/O capability through expansion header J5, which offers 16 LVDS-capable differential pairs routed with controlled 100Ω differential impedance and matched trace lengths. These signals connect directly to the XC4VSX35 FPGA's differential-capable I/O banks (e.g., Banks 3, 5, 7, 8, 9), enabling reliable LVDS, RSDS, or BLVDS interface validation on the HW-V4-ML402-UNI-G.

What peripheral interfaces are included on the HW-V4-ML402-UNI-G board?

The HW-V4-ML402-UNI-G includes RS-232 serial, PS/2 keyboard/mouse ports, stereo AC97 audio codec (with line-in/out, mic-in, and 50-mW headphone drive), USB 2.0 host/peripheral (via Cypress CY7C67300), 10/100/1000 Ethernet PHY, I²C bus with 4-Kb EEPROM, and a 16×2 character LCD. All interfaces are hardwired to the XC4VSX35 FPGA with no external level-shifting or protocol translation required.
