1. General description
The SAA7803 has the same Features and pinning as the SAA7804 and SAA7806 devices. The SAA7803 is a multi chip module containing two additional memories, flash and SRAM, to support code development. This IC is intended for development use only and may therefore not ply with all aspects of the Philips Semiconductors general quality specification for integrated circuits (SNW-FQ-611). This IC can therefore also not be the subject of any existing or future quality agreement. All warranties are hereby disclaimed and Philips accepts no liability or indemnity whatsoever as to the use of this IC. This IC contains multiple memories along side the audio device resulting in higher levels of emitted noise which may fail FCC certification in some application. For production the SAA7804 or SAA7806 must be used.
2. Features
2.1 Hardware Features s Channel decoder based on SAA7817 IC design s Digital servo based on SAA7824 IC design s 32-bit embedded ARM7 RISC microprocessor supporting both 32-bit and 16-bit Thumb® instruction sets s Mask programmed internal program ROM for microprocessor s Additional memory for code development s Register structure redesigned to utilize the plete 32-bit bandwidth of the integrated microprocessor bus architecture s Programmable clock frequency for ARM® microprocessor
- allowing users to trade-off power consumption and processing power depending on requirements s Microprocessor access to digital representations of the diode input signals from the optical pick up; the microprocessor can also generate the servo output signals RA, FO, SL and allows the possibility of additional servo algorithms or a plete servo implementation in software s Microprocessor access to audio streams; both from the internal CD decoder and an external stereo auxiliary input (e.g. an analog source from a tuner; converted to digital via on-chip...
