EP7209
I
Audio decoder system-on-chip
— Allows for support of multiple audio decompression
algorithms
— Supports MPEG 1, 2, & 2.5 layer 3 audio decoding,
including ISO compliant MPEG 1 & 2 layer 3 support for
all standard sample rates and bit rates
— Supports bit streams with adaptive bit rates
— DAI (Digital Audio Interface) providing glueless interface
to low power DACs, ADCs, and Codecs
I
Ultra low power consumption for MP3 playback
— 87 mW (typical) for 44.1 kHz samples/sec,
128 kbits/second
— 50 mW for 22.05 kHz samples/sec, 64 kbits/second
— <1 mW in Standby State
I
ARM720T processor
— ARM7TDMI CPU
— 8 kbytes of four-way set-associative cache
— MMU with 64-entry TLB (transition look-aside buffer)
— Write Buffer
— Windows
CE enabled
— Thumb code support enabled
The EP7209 is a complete integrated system on a
chip for enabling personal digital audio solutions. It
is designed specifically for implementing audio
processing algorithms in power sensitive applica-
tions. The core-logic functionality of the device is
built around an ARM720T embedded processor.
The EP7209 also includes a 32-bit Y2K-compliant
Real-Time Clock (RTC) and comparator.
