STMicroelectronics STV-674/100T-E01

Overview

STV-674/100T-E01 from STMicroelectronics is an evaluation kit for the STV0674 CMOS digital camera signal processor, paired with the VV6501 VGA CMOS image sensor. It supports three operational modes: Camera (still/motion/audio capture), WebCam (DirectShow-compliant real-time VGA video at up to 30 fps), and Native Mass Storage (NMS) mode presenting onboard NAND flash as a removable USB disk drive.

For engineers reviewing the STV-674/100T-E01 datasheet, STV-674/100T-E01 pinout, STV-674/100T-E01 application, or STV-674/100T-E01 equivalent, this kit enables rapid validation of imaging pipeline integration, USB composite device enumeration, NMS-class storage behavior, and synchronized audio/video capture in embedded USB-peripheral camera designs.

Technical Context

The STV-674/100T-E01 implements a complete tri-mode imaging subsystem: in Camera mode, it captures stills, AVI-formatted video clips (via AVICreate), and audio using on-board peripherals; in WebCam mode, it enumerates as a USB 1.1 composite device with DirectShow driver support and real-time video streaming capability.

NMS mode exposes ~400 KB/s write and ~500 KB/s read throughput from DOS-formatted NAND flash, enabling host-side file-based access without custom drivers. The kit integrates the STV0674T100 processor and VV6501C001 sensor on a single PCB with USB interface, power regulation, and flash memory management logic.

FAQ

What is the primary function of the STV-674/100T-E01 evaluation kit?

The STV-674/100T-E01 is a fully assembled evaluation platform for the STV0674 imaging DSP and VV6501 VGA sensor. It demonstrates tri-mode operation: standalone camera (stills/video/audio), USB WebCam (DirectShow-compatible VGA streaming), and Native Mass Storage (NAND flash appearing as removable disk). It includes schematics, BOM, USB cable, and AVICreate conversion software.

Does the kit support Windows and macOS host operating systems?

Yes - NMS mode is supported on Windows 98SE through XP and Mac OS 9/macOS X. WebCam mode requires Windows with DirectShow (Windows 98SE+, DirectX 8.1+); macOS does not support the WebCam or Camera modes, only NMS mode for file access. No Linux driver support is documented.

What are the minimum host system requirements for full functionality?

A Pentium II 266 MHz PC with 64 MB RAM (Win98/ME) or 128 MB RAM (Win2K/XP), 800×600 graphics adapter, CD-ROM drive, and USB port is required. Host must run Windows 98SE, ME, 2000 SP3, or XP SP1; DirectX 8.1+ is mandatory for WebCam mode video preview and capture.

Is the STV-674/100T-E01 pin-compatible with the STV-674/501C-R01 reference design?

No - STV-674/100T-E01 is an evaluation kit intended for lab validation and software development; STV-674/501C-R01 is a production-oriented reference design board with full schematic, BOM, and layout files. They share the same core ICs (STV0674T100 + VV6501C001) but differ in PCB implementation, firmware, and target use case.
