The EP9307 is an ARM920T-based system-on-a-chip

(SOC) design with a large peripheral set targeted to a

variety of applications:

• Thin client computers for business and home

• Internet radio

• Internet access devices

• Industrial computers

• Specialized terminals

• Point of sale terminals

• Test and measurement equipment

The ARM920T microprocessor core with separate 16-

kbyte, 64-way set-associative instruction and data

caches is augmented by the MaverickCrunch™ co-

processor, enabling high-speed floating point

calculations.

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 (MAC) is included along with external

interfaces to SPI, I

S audio, Raster/LCD, keypad and

touchscreen. A three-port USB 2.0 Full-speed Host

(OHCI) (12 Mbits per second) and three UARTs are

included as well.

The EP9307 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).
