Microchip Technology UFX6000-VE

Overview

UFX6000-VE from SMSC is a single-chip USB 2.0 Hi-Speed (480 Mbps) graphics controller integrating USB 2.0 Device Controller + PHY, HDMI/DVI v1.3/v1.0 controller + PHY, triple 10-bit Video DAC for VGA output, and JEDEC-compliant DDR2 SDRAM controller with 16-bit data/13-bit address bus - deployed in docking stations, USB monitors, and thin clients requiring multi-interface display extension.

For engineers reviewing the UFX6000-VE datasheet, UFX6000-VE pinout, UFX6000-VE application, or UFX6000-VE equivalent, key selection criteria include its 225-ball LFBGA package, 0°C to +70°C commercial temperature range, support for QWXGA (2048×1152) resolution, integrated S/PDIF/I2S audio interface for HDMI, and dual-mode digital RGB (12/15-bit DDR or 24-bit SDR).

Technical Context

The UFX6000-VE implements a tightly coupled graphics pipeline: USB Bulk-Out transfers compressed or uncompressed pixel data to the Graphics Engine, which decompresses using algorithms optimized for speed and fidelity before staging into external DDR2 SDRAM via the integrated DDR2 PHY and controller. Display timing and pixel routing are managed by the Display Controller, feeding outputs simultaneously to HDMI/DVI, VGA (via triple 10-bit DAC), or digital RGB interfaces.

Its USB subsystem operates exclusively in Hi-Speed mode with three endpoints (Control, Bulk-Out, Interrupt-In), integrated termination resistors, and short-circuit protection on differential lines. The HDMI/DVI block supports DDC2B/EDID for plug-and-play monitor identification, while the digital RGB interface provides configurable 12/15-bit DDR or 24-bit SDR modes with dedicated VCLK/nVCLK, HSYNC, VSYNC, and nBLANK signals.

Key Specifications

Pinout & Package

UFX6000-VE is housed in a 225-ball Low-Profile Fine-Pitch Ball Grid Array (LFBGA) package, RoHS compliant, with 0.8 mm ball pitch and 13 mm × 13 mm body size per SMSC package outline documentation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar USB-to-graphics applications.

Compared with ASM1083 and RTL8153B, the UFX6000-VE uniquely integrates USB 2.0 device controller, HDMI/DVI PHY, VGA DAC, and DDR2 SDRAM controller in one die - enabling single-chip USB display adapters without external graphics or memory controllers.

Availability

UFX6000-VE is available at Aetrix Electronics and suitable for USB docking stations, thin client terminals, and embedded digital signage requiring stable component supply, commercial-temperature operation, and long-term lifecycle support.

Supply support for UFX6000-VE includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

SMSC (Standard Microsystems Corporation), acquired by Microchip Technology in 2012, specialized in connectivity ICs including USB, Ethernet, and embedded controllers before integration into Microchip's analog and interface portfolio.

The UFX6000 product line was designed specifically for cost-sensitive, space-constrained USB-to-video bridging - targeting high-volume consumer and commercial peripherals where integration, driver compatibility, and multi-interface flexibility were critical.

FAQ

What operating systems does the UFX6000-VE support with official drivers?

The UFX6000-VE supports Microsoft Windows XP, Vista, and 7 with fully certified drivers provided by SMSC. No official Linux, macOS, or Windows 8+ drivers were released; third-party open-source efforts exist but lack HDMI audio or advanced gamma control. The UFX6000-VE relies on these legacy Windows drivers for full feature enablement including triple-buffering and EDID handling.

Does the UFX6000-VE require an external DDR2 SDRAM chip to function?

Yes, the UFX6000-VE requires an external JEDEC-compliant DDR2 SDRAM chip connected via its 16-bit data and 13-bit address bus - it contains no embedded memory. Typical configurations use 64 Mbit × 16 devices (e.g., 128 MB total) for QWXGA frame buffering. The UFX6000-VE's integrated DDR2 PHY handles all timing and signal integrity requirements.

Can the UFX6000-VE output HDMI and VGA simultaneously?

No, the UFX6000-VE does not support simultaneous HDMI and VGA output. Its display controller routes pixel data to one active interface at a time - either HDMI/DVI, VGA (via DAC), or digital RGB. Mode selection is configured via EEPROM or software registers; concurrent dual-output operation is not supported in hardware or firmware.

What is the role of the XI/XO pins on the UFX6000-VE?

The XI and XO pins form the 25 MHz crystal oscillator interface for the UFX6000-VE's internal PLLs - generating clocks for USB, HDMI, and system logic. XI accepts either a 25 MHz crystal or single-ended clock source; XO must be left unconnected if using an external oscillator. This 25 MHz reference is mandatory for USB Hi-Speed compliance and HDMI timing accuracy.

Is the UFX6000-VE pin-compatible with other SMSC UFX-series parts like UFX6000-VB or UFX6000-VC?

No, the UFX6000-VE is not pin-compatible with UFX6000-VB or UFX6000-VC. While all share the same 225-ball LFBGA footprint, pin assignments differ significantly - particularly for DDR2, HDMI, and GPIO signals - as confirmed in SMSC's separate package drawings and pinout tables for each variant. Board reuse requires full schematic and layout revision.
