STV0684

Overview

The STV0684 is a single-chip digital camera processor designed for SXGA and UXGA CMOS sensors. It integrates an ST20-C103 core running at 48 MHz, a video processor with patented NORA noise reduction, and a JPEG/MJPEG codec. The device supports USB 1.1 compliance for mass storage and audio/video streaming, alongside interfaces for Compact-Flash, SmartMedia, NAND flash, and SD/MMC cards. It features on-chip 16-bit Sigma-Delta ADC for recording and PWM DAC for playback, plus PAL/NTSC TV encoding. Power supplies are 3.3V and 1.8V with typical current of 60 mA.

Feature Summary

• ST20-C103 core with 64 KB SRAM, caches, and boot ROM for firmware execution in external SDRAM or NAND.
• Video processor supporting UXGA (1600x1200) and SXGA (1280x1024) with defect correction and anti-vignetting.
• Integrated USB 1.1 interface compliant with Mass Storage, Audio, and Video classes.
• On-chip 16-bit Sigma-Delta ADC for audio input and PWM DAC for audio output.

Applications

• Digital still cameras
• Solid state video camera recorders
• Embedded cameras

Procurement Notes

Verify the package type as BGA196 (12x12 mm). Confirm that the product information is preliminary and subject to change without notice. Ensure compatibility with required external memory components such as SDRAM and mass storage media like Compact-Flash or NAND.

Selection Notes

Select this component for applications requiring integrated processing for high-resolution CMOS sensors up to UXGA. Consider the need for external SDRAM and mass storage interfaces. Verify support for specific display panels via the flexible TFT interface and check if USB connectivity meets system requirements for data transfer and peripheral connection.

Part Context

The STV0684 serves as a central processing unit for compact digital imaging systems. It combines image signal processing, compression, and connectivity in a single chip, reducing the bill of materials by integrating functions typically handled by multiple discrete components.
