Description

The low-power high-performance CS89712 is designed

for ultra-low-power communication applications such as

VoIP telephones, industrial control, data acquisition,

special purpose servers and RF to Ethernet bridges. The

core-logic functionality of the device is built around an

ARM720T processor with 8 Kbytes of four-way set-asso-

ciative unified cache and a write buffer. Incorporated into

the ARM720T is an enhanced memory management unit

(MMU) which allows for support of sophisticated operat-

ing systems like embedded Linux.

The CS89712 Ethernet port includes on-chip RAM and

10BASE-T transmit and receive filters.
