1. General Description
The SPCA533A is a highly integrated solution for DSC (Digital Still Camera) application. It consists of image processing engine, image
compression engine, the storage interface controller, TV encoder, LCD interface controller and USB interface. The SPCA533A supports a
wide range of sensors, including most-commonly used CMOS and CCD sensors. Flexible control of the internal buffer allows the SPCA533A
chip to support up to 4-mega pixels image resolution. It also supports many flash memory card interfaces, including CFC, MMC, SMC, and
SD. The SPCA533A can also interface to both TFT LCD panels and STN LCD panels for preview. With the fully supports to a DSC's major
peripherals, the customers can realize a DSC system with the minimum cost.

Sensor Interface: The sensor interface connects to the CMOS or CCD sensors. It can also connect to a video decoder to capture video.
The SPCA533A has built-in a timing generator for the commonly used CCD sensors. A serial interface is used to program the CMOS
sensors and external CDS/AGC chips for CCD sensors.
RTC: The RTC module enables the SPCA533A to maintain the calendar function with the minimum power consumption.
PLL: The SPCA533A has on-chip PLL that allows minimal number of crystals in user applications. The major internal clocks can be
generated with a single 27MHz crystal.
8032: The built-in 8032 CPU coordinates the camera operation. The CPU can be disabled when the SPCA533A is connected to an external
ICE.
TV/LCD Interface Controller: This module has integrated a variety of digital interfaces, which include TFT LCD interface, STN LCD
interface, and digital video output interface. It also integrates a TV encoder, supporting both NTSC and PAL composite signal output. The
OSD function is also implemented in this module. Both font-based and graphic-based OSD functions are supported.

Color DSP: Image processing engine of the SPCA533A is a very flexible pipeline. It will perform color interpolation, gamma correction,
image scaling for digital zoom, and image enhancement filtering.
JPEG Engine: This image compression engine can generate JPEG compressed file in JFIF and EXIF format with firmware support. The
engine can also decode JPEG compressed image for playback.
DRAM Controller: The DRAM controller provides access path to the SDRAM for the other internal modules of the SPCA533A. Many special
functions are also implemented in this module. For example, image scaling, copy and paste of image parts, image rotation, ... etc.
DMA Controller: The DMA controller allows high-speed data transfer between SPCA533A internal modules.
Storage Media Interface Controller: The storage interface controller is a high efficiency bridge between different storage media protocol
and the internal bus. Both DMA data transfer and PIO data transfer are supported.
Audio Controller: The SPCA533A's audio controller has built-in standard IMA-ADPCM audio compression. It also integrates the AC-link
interface.
USB1.1 Controller: The USB controller allows the SPCA533A to communicate with a PC or Mac. The SPCA533A supports all types of USB
pipes. (isochronous, bulk, control and interrupt)
