OVERVIEW
(cont.)
The EP7312 is designed for ultra-low-power operation.
Its core operates at only 2.5 V, while its I/ O has an
operation range of 2.5 V–3.3 V. Thedevicehas three basic
power states: operating, idleand standby.
MaverickKey unique hardware programmed IDs are a
solution to the growing concern over secure web content
and
commerce. With Internet security
important role in the delivery of digital media such as
books or music, traditional softwaremethods arequickly
becoming unreliable. The MaverickKey unique IDs
provide OEMs with a method of utilizing specific
hardware IDs such as those assigned for SDMI (Secure
Digital Music Initiative) or any other authentication
mechanism.

The EP7312 integrates an interface to enable a direct
connection to many low cost, low power, high quality
audio converters. In particular, high quality ADCs,
DACs, or CODECs such as the Cirrus Logic CS53L32A,
CS43L42, and CS42L50 are easily added to an EP73xx
design via the DAI. Some of these devices feature digital
bass and treble boost, digital volume control and
compressor-limiter functions.
Simply by adding desired memory and peripherals to the
highly integrated EP7312 completes a low-power system
solution. All necessary interface logic is integrated on-
chip.
