EP9302 General Description

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™ coprocessor 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-todigital converter (ADC) are included as well.

The EP9302 is a high-performance, low-power RISCbased, 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).
