STV0674T100

Overview

The STV0674T100 is a CMOS digital camera co-processor designed for use with STMicroelectronics CIF (352x288) or VGA (640x480) image sensors. It integrates a video processor, JPEG compression engine, and an embedded 8052 microcontroller with 32 Kbytes of ROM and 32 Kbytes of SRAM. The device supports USB 1.1 connectivity for tethered operation and external memory interfaces including SDRAM, NAND flash, and SmartMedia cards for untethered capture. It features hardware color processing, auto white balance, and audio recording/playback capabilities.

Feature Summary

• Integrated hardware JPEG compression and video processing for up to 30fps VGA output
• Embedded 8052 microcontroller with 32 KB ROM and 32 KB SRAM
• USB 1.1 compliant interface supporting simultaneous video and audio capture
• Supports external SDRAM, NAND flash, and SmartMedia card interfaces

Applications

• Low-cost USB webcams with simultaneous audio capture
• Dual-mode cameras combining webcam functionality with digital still photography
• Tri-mode cameras featuring camcorder and dictaphone modes

Procurement Notes

Verify the package type matches the 100-TQFP (14x14 mm) specification. Confirm that the ordering suffix 'T100' corresponds to the tube packaging format as indicated in local product fields. Ensure compatibility with the required 3.3V I/O and 1.8V core voltage supplies during system design.

Selection Notes

Select this component when designing systems requiring integrated sensor control, color processing, and USB connectivity without a separate host processor. It is suitable for applications needing flexible memory options like SDRAM or NAND flash. Consider the 32 KB internal SRAM limit for firmware complexity in untethered modes.

Part Context

The STV0674 is part of STMicroelectronics' specialized imaging chipset family, designed to work specifically with their range of CMOS image sensors. It serves as a complete solution for implementing low-cost digital imaging products by handling sensor timing, image processing, and data transfer protocols internally.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Designers should verify pinout and functional compatibility if considering alternative vendors for similar camera co-processors.
