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
