Integrated Two-port USB 2.0 Full Speed Host
with Transceivers
The EP9301 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 EP9301 integrates a 1/10/100 Mbps
Ethernet Media Access Controller (MAC)
on board. With a simple connection
to an MII-based external PHY, an
EP9301-based system has easy, high-
performance, cost-effective Internet
capability.
High-Quality Sound Delivered in
Multiple Audio Configurations
The EP9301 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
General-Purpose Memory Interface (SDRAM,
SRAM, ROM, & FLASH)
The EP9301 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 EP9301 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 EP9301.
