SUMMARY
Note: This datasheet is preliminary. This document contains
material that is subject to change without notice.
High performance 32-bit/40-bit floating point processor
optimized for high performance audio processing
Single-instruction, multiple-data (SIMD) computational
architecture
with unique audiocentric peripherals such as the digital
applications interface, DTCP (digital transmission content
protection protocol), serial ports, precision clock genera-
tors, S/PDIF transceiver, asynchronous sample rate
converters, input data port, and more.
For complete ordering information, see Automotive Prod-
ucts on Page 59 and Ordering Guide on Page 59.
On-chip memory—5 Mbits of on-chip RAM, 4 Mbits of on-chip
ROM
Automotive applications—the ADSP-21462W and the ADSP-
21465W are available exclusively as automotive products
