SM5901AF compression and non compression type anti-shock memory controller with built-in 1M DRAM NIPPON PRECISION CIRCUITS INC. Overview The SM5901 is a compression and non compression type anti-shock memory controller with built-in 1M DRAM LSI for compact disc players. The compression level can be set in 4 levels, and external 1M DRAM can be connected to expand the memory to 2M bits. Digital attenuator, soft mute and related functions are also incorporated. It operates from a 2.7 to 3.3 V wide.

SM5901AF Features

* - 2-channel processing - Serial data input
