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
The SPCA504A supports JPEG image compression at YUV422 and YUV 420 chroma format. It can also compress BW (black-and-white) images. The output data format is compliant with JFIF bitstream format. An automatic scale-down function is included to fit in the display size under playback mode.
The USB interface supports following pipes to PC. They are:
Video ISO-IN pipe : for video data transmission to the PC
Audio ISO-IN pipe : for Audio data transmission to the PC
BULK-IN pipe : for uploading image from the camera to the PC
BULK-OUT pipe : for download image data, audio data, firmware, and MP3 data to the camera.
INTERRUPT-IN pipe: For reporting status and events of the camera to the PC
The SPCA504A has a built-in 8032 micro-controller with 6K bytes of internal SRAM.
It supports ISP (in-system-programming with 4K bytes of shadow space).
It has built-in 64K bytes of mask ROM.
It supports LOW-POWER mode and IDLE mode.
The SPCA504A has a built-in PLL to supply on-chip clock sources.
The SPCA504A is packaged in either 128-pin QFP or 160-pin LQFP.
The SPCA504A needs 3.3/2.5 dual power supply.
