ADSP-21368 is a high performance 32-bit floating-point SHARC processor for professional audio applications. 32-bit external memory interface supporting glue-less interface to SDRAM, SRAM and flash. The processors are 32-bit/40-bit floating-point processors optimized for high performance automotive audio applications with its large on-chip SRAM, mask programmable ROM, multiple internal buses to eliminate I/O bottlenecks, and an innovative digital applications interface (DAI). The ADSP-21368 increases the amount of on-chip memory to 2MB SRAM and 6MB ROM while integrating a variety of audio-specific and general purpose peripherals. Peripherals such as an all digital S/PDIF transmitter/receiver, 8-ch asynchronous sample rate converter, 8 high-speed serial ports, 4 precision clock generators and multiple serial interfaces combine to ensure the ADSP-21368 maximizes system throughput while minimizing system bill of materials costs.
