MaverickKey™ Unique ID Secures
Digital Content and OEM Designs
MaverickKey unique hardware
programmed IDs provide an excellent
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 for DRM (Digital
Rights Management) mechanisms.
Both a specific 32-bit ID as well as a
128-bit random ID is programmed into
the EP9302 through the use of laser
probing technology. These IDs can then
be used to match secure copyrighted
content with the ID of the target device
that the EP9302 is powering, and then
deliver the copyrighted information
over a secure connection. In addition,
secure transactions can benefit by
matching device IDs to server IDs.
MaverickKey IDs can also be used by
OEMs and design houses to protect
against design piracy by presetting
ranges for unique IDs. For more
information on securing your design
using MaverickKey, please contact your
Cirrus Logic sales representative.
Integrated Two-port USB 2.0
Full Speed Host with Transceivers
The EP9302 integrates two USB 2.0 Full
Speed host ports. Fully compliant to the
OHCI USB 2.0 Full Speed specification
(12 Mbps), the host ports can be used
to provide connections to a number of
external devices including mass storage
devices, external portable devices such
as audio players or cameras, printers
or USB hubs. Naturally, the two-port
USB host also supports the USB 2.0
Low Speed standard. This provides
the opportunity to create a wide array
of flexible system configurations.
Integrated Ethernet MAC Reduces BOM Costs
The EP9302 integrates a 1/10/100
Mbps Ethernet Media Access
Controller (MAC) on board. With a
simple connection to an MII-based
external PHY, an EP9302-based
system has easy, high-performance,
cost-effective Internet capability.
High-Quality Sound Delivered in
Multiple Audio Configurations
The EP9302 delivers SPI, I
serial interface support. The AC’97 port
supports multiple CODECs for cost-
effective stereo audio output. Cirrus
Logic provides high-performance audio
decode and encode algorithms for a
number of popular formats including MP3,
Windows Media
®
Audio and AAC™.

General-Purpose Memory Interface
(SDRAM, SRAM, ROM, & FLASH)
The EP9302 features a unified memory
address model in which all memory
devices are accessed over a common
address/data bus. The SRAM memory
controller supports 8- or 16-bit devices
and accommodates an internal boot
ROM concurrently with a 8- or 16-bit
SDRAM memory.
Multiple Booting Mechanisms
Increase Flexibility
The processor includes a 16 KB boot
ROM to set up standard configurations.
Optionally, the processor may be booted
from FLASH memory, over the SPI serial
interface or through the UART. This boot
flexibility makes it easy to design user-
controlled, field-upgradable systems.
Abundant General Purpose I/Os
Build Flexible Systems
The EP9302 includes both enhanced
and standard general- purpose I/O pins
(GPIOs). The 16 different enhanced
GPIOs may individually be configured
as inputs, outputs or interrupt-enabled
inputs. There are an additional 8 standard
GPIOs that may individually be used as
inputs, outputs or open-drain pins. The
standard GPIOs are multiplexed with
peripheral function pins, so the number
available depends on the utilization of
peripherals. Together, the enhanced
and standard GPIOs facilitate easy
system design with external peripherals
not integrated on the EP9302.
