STMicroelectronics STV-676-E01

Overview

STV-676-E01 from STMicroelectronics is an evaluation kit for the STV0676 CMOS imaging digital signal processor, enabling real-time VGA (640×480 @ 30 fps) and CIF (352×288) video capture with MJPEG compression, I²C programmability, and USB 1.1 interface compliance. It integrates VV6501 (VGA) and VV6411 (CIF) sensor daughter boards, digiport video output, and WinXP WHQL-certified DirectShow V2.0 driver.

For engineers reviewing the STV-676-E01 datasheet, STV-676-E01 pinout, STV-676-E01 application, or STV-676-E01 equivalent, this kit supports embedded vision prototyping, USB-based PC camera development, I²C register-level tuning of image processing parameters, and MJPEG-compressed video streaming over digiport or USB.

Technical Context

The STV-676-E01 implements a hardware-accelerated imaging pipeline centered on the STV0676 companion processor, which performs auto-exposure, auto-white-balance, gamma correction, and on-the-fly MJPEG encoding. Its digiport provides 8-bit parallel YCrCb/RGB preview or compressed MJPEG data output.

I²C control is routed via a dedicated parallel-port-to-I²C adapter cable (included), allowing register-level configuration of the STV0676 without host CPU intervention. USB 1.1 connectivity uses a standard A-B cable and delivers full-motion VGA video to Windows hosts using WHQL-certified drivers.

FAQ

Does STV-676-E01 support USB 2.0 or higher?

No. The STV-676-E01 is strictly USB 1.1 compliant, with maximum bandwidth limited to 12 Mbps. It does not support USB 2.0 High-Speed mode or later revisions. Video throughput is capped at VGA@30fps with MJPEG compression, consistent with USB 1.1 physical layer constraints.

Can the digiport output be used without the STV0676 processor running?

No. The digiport is a dedicated parallel video interface driven exclusively by the STV0676 ASIC. It requires active clocking, sensor synchronization, and internal pipeline enablement. No passive or bypass mode exists - all digiport data originates from the STV0676's real-time processing engine.

Is Windows 10 or Linux driver support available?

No official Windows 10 or Linux drivers are provided. Only Windows 98 and Windows XP (WHQL-certified DirectShow V2.0 and VfW via mapper) are supported per the 2003 documentation. Modern OS compatibility requires third-party reverse-engineered or wrapper solutions, not validated by STMicroelectronics.

What sensors are natively supported on the STV-676-E01 board?

The kit includes two pre-mounted sensor daughter boards: VV6501 (VGA resolution, 640×480) and VV6411 (CIF resolution, 352×288). These are the only sensors electrically and firmware-supported; no other CMOS imagers are compatible without redesigning sensor interface timing and register mapping.
