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-associative 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 embedded Linux.
