EP9302

High-speed ARM9 System-on-chip Processor with MaverickCrunch

The EP9302 is an ARM920T-based system-on-a-chip

design with a large peripheral set targeted to a variety of

applications:

•

Industrial controls

•

Digital media servers

•

Integrated home media gateways

•

Digital audio jukeboxes

•

Streaming audio players

•

Set-top boxes

•

Point-of-sale terminals

•

Thin clients

•

Biometric security systems

•

GPS & fleet management systems

•

Educational toys

•

Industrial computers

•

Industrial hand-held devices

•

Voting machines

•

Medical equipment

The EP9302 is one of a series of ARM920T-based

devices. Other members of the family have different

peripheral

sets,

coprocessors

and

package

configurations.

The ARM920T microprocessor core with separate

16 kbyte, 64-way set-associative instruction and data

caches is augmented by the MaverickCrunch™ co-

processor enabling faster than real-time compression of

audio CDs.

The 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.

A high-performance 1/10/100 Mbps Ethernet media

access controller (EMAC) is included along with external

interfaces to SPI, AC’97, and I2S audio. A two-port USB

2.0 Full-speed Host (OHCI) (12 Mbits per second), two

UARTs, and a analog voltage measurement analog-to-

digital converter (ADC) are included as well.

The EP9302 is a high-performance, low-power RISC-

based, single-chip computer built around an ARM920T

microprocessor core with a maximum operating clock

rate of 200 MHz (184 MHz for industrial conditions). The

ARM core operates from a 1.8 V supply, while the I/O

operates at 3.3 V with power usage between 100 mW

and 750 mW (dependent on speed).
