The fully static EP7312 is optimized for low power
dissipation and is fabricated using a 0.25 micron CMOS
process.
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. The device has three basic power states:
operating, idle and standby.
MaverickKey unique hardware programmed IDs are a solution
to the growing concern over secure web content and
commerce. With Internet security playing an important role in
the delivery of digital media such as books or music,
traditional software methods are quickly 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.
