compression and non compression type

shock-proof memory controller

Overview

The SM5902 is a compression and non compres-

sion type shock-proof memory controller LSI for

compact disc players. The compression level can

be set in 4 levels, and external memory can be

selected from 4 options (1M, 4M, 4M脳 2, 16M).

Digital attenuator, soft mute and related functions

are also incorporated. It operates from a 2.4 to 5.5

V wide supply voltage range.
