BU9534KV
BU9534KV is Signal processor LSI with anti-shock memory controller for CD players manufactured by LSI Computer Systems.
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.
