Product Summary
The SM5902AF is a compression and non compression 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´ 2, 16M). Digital attenuator, soft mute and related functions are also incorporated. The SM5902AF operates from a 2.4 to 5.5 V wide supply voltage range.
