Signal processor LSI with anti-shock memory controller for CD players
BU9534KV
Description
BU9534KV is a digital signal processor LSI with built-in
pre-servo amplifier, and anti-shock memory controller
developed for CD players. This pre-servo amplifier is
applied to CD-RW disc. Approximately 180sec. music
data can be stored in memory by connecting with 64M
bit SDRAM.
