Description

The CL-PS7111 is designed for ultra-low-power applications such as organizers/PDAs, two-way pagers, smart phones, and hand-held internet appliances.

The core-logic functionality of the device is built around an ARM710a microprocessor with 8 Kbytes of four-way set-associative unified cache. At 18.432 MHz (for 3.3-V operation), the CL-PS7111 delivers nearly 15 Vax-MIPS of performance (based on Dhrystone â benchmark) roughly the same level of performance offered by a 33-MHz Intel â '486-based PC.
