 Description

The EP9315 is a highly integrated system-on-chip processor that paves the way for next-generation consumer and industrial electronic products. The EP9315 features an advanced 200 MHz ARM920T processor design with a memory management unit (MMU) that supports Linux? Windows CE?and many other embedded operating systems. The ARM920T's 32-bit microcontroller architecture, with a five-stage pipeline, delivers impressive performance at very low power.

Designers of digital media servers, jukeboxes, telematic control systems, thin clients, set-top boxes, point-of-sale terminals, industrial controls, biometric security systems and GPS devices will benefit from the EP9315's integrated architecture and advanced features. In fact, with its broad range of peripheral interfaces, the EP9315 is suited to even more applications. By enabling or disabling the EP9315's peripheral interfaces, designers can also reduce development costs and accelerate time to market by creating a single platform that can be modified to deliver differentiated end products.

Cirrus Logic's embedded processor products are complemented by a range of complete operating systems. Both Microsoft?Windows CE.NETand Linux?solutions are available with total driver support.
