The EP7211 is designed for ultra-low-power applica-
tions such as organizers/PDAs, two-way pagers,
smart cellular phones, and industrial hand-held infor-
mation 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.
