Description

The EP7211 is designed for ultra-low-power applications such as organizers/PDAs, two-way pagers, smart cellular phones, and industrial hand-held information appliances. The core-logic functionality of the device is built around an ARM720T processor with 8 kbytes of four-way set-associative unified cache and a write buffer. Incorporated into the ARM720T is an enhanced memory management unit (MMU), which allows for Microsoft Windows CE support.

The EP7211 also includes a 32-bit Y2K-compliant Real Time Clock (RTC) and comparator.
