EP7312-90 Features (cont.)
Advanced audio decoder/decompression capability
Allows support of multiple audio decompression
algorithms
Supports MPEG 1, 2, and 2.5 layer 3 audio decoding,
including ISO compliant MPEG 1 and 2 layer 3
support for all standard sample rates and bit rates
Supports bit streams with adaptive bit rates
Improved DAI (Digital Audio Interface) providing
glueless interface to low-power DACs, ADCs, and
CODECs
SDRAM controller
Supports two memory banks of up to 256 Mbits in
size
SDRAM memory interface is programmable from 4
to 32 bits wide
LCD controller
Interfaces directly to a single-scan panel
monochrome or color STN LCD
