SM5903BF NIPPON PRECISION CIRCUITS INC. compression and non compression type shock-proof memory controller Overview The SM5903BF 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). It operates from a 2.4 to 3.6 V supply voltage range. Features - 2-channel processing - Serial data input ⋅ 2s complement, 16-bit/MSB first, right-justified format ⋅ Wide capture function (up to 3 × speed input rate) - System clock input ⋅ 384fs (16.9344 MHz) - Shock-proof memory controller ⋅ ADPCM compression method ⋅ 4-level compression mode selectable 4-bit compression mode 2.78 s/Mbit 5-bit compression mode 2.
