Preliminary

Data Sheet

SPCA504A

1. General description

The SPCA504A is a digital camera processor chip that provides a complete solution for dual mode camera

applications. This chip integrates image sensor interface, digital video input interface, color image processor,

storage media controller, JPEG image compression engine, USB interface, and a built-in micro-controller. The

SPCA504A supports both CCD and CMOS image sensors up to 1.1M and 2.0M pixels respectively. It is

designed to fulfill all the requirements for the dual mode camera applications. The SPCA504A camera processor

chip includes not only the latest technology, but also the full services and support of Sunplus.

2. Feature

The main functions of the SPCA504A includes:

● DSC mode

: capture one frame each time

● Video clip mode : capture a video with frame rate 15~30 frames/sec

● PC-camera mode : 30 frames/sec for CIF size, 20 frames/sec for VGA size

The SPCA504A chip has many image-processing functions that include:

● High quality color interpolation

● Two-dimensional edge enhancement

● Bad pixels concealment

● AE/AWB parameter windows cover full range of the sensor

The SPCA504A supports image CCD/CMOS sensors up to 1.1M/2.1M pixels. Some of them are listed below.

Semiconductor CS2102

● SVGA: HYUNDAI HV7141B

● XGA : PIXELCAM PCS2112

● SXGA: Motorola MCM20027

The DRAM interface supports 16M bits and 64M bits SDRAM modules through a 16-bit data bus.

Audio functions that the SPCA504A supports include audio class, audio capture, audio record and playback.

● It supports bi-directional AC-link for audio record and playback.

● It supports MP3 decoder interface for MP3 decoding and playback.

● It supports microphone interface for audio record.

● It supports an IMA-ADPCM compatible ADPCM compression engine for audio compression.

In addition to the external SDRAM module, the SPCA504A supports many storage media. That include:

● NAND-gate flash memory (smart media card)

● NOR-type flash memory

● ATAPI interface (ATAPI CDRW, compact flash memory)

● SPI serial flash memory, both mode0 and mode 3 supported (MultiMediaCard)

● Next Flash serial flash memory

● SD Card
