EP7311

The Maverick™ EP7311 is designed for ultra-low-power applications such as PDAs, smart cellular phones, and industrial hand held information appliances. The corelogic functionality of the device is built around an ARM720T processor with 8 KB of four-way setassociative unified cache and a write buffer. Incorporated into the ARM720T is an enhanced memory management unit (MMU) which allows for support of sophisticated operating systems like Linux®.

The EP7311 is designed for low-power operation. Its core operates at only 2.5 V, while its I/O has an operation range of 2.5 V3.3 V. The device has three basic power states: operating, idle and standby.

One of EP7311's notable features is MaverickKey unique IDs. These are factory programmed IDs in response 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 consist of two registers, one 32-bit series register and one random 128- bit register that may be used by an OEM for an authentication mechanism.

Simply by adding desired memory and peripherals to the highly integrated EP7311 completes a low-power system solution. All necessary interface logic is integrated onchip.
