OVERVIEW
The EP7309 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.

I The fully static EP7309 is optimized for low power
The EP7309 integrates an interface to enable a direct
connection to many low cost, low power, high quality
audio converters. In particular, the DAI can directly
interface with the Crystal‚ CS43L41/42/43 low-power
audio DACs and the Crystal‚ CS53L32 low-power ADC.
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 EP7309 completes a low-power system
solution. All necessary interface logic is integrated on-
chip.
