The EP9302 runs at 200 MHz and includes a "MaverickCrunch" engine, described by Cirrus as "an advanced, mixed-mode math coprocessor that greatly accelerates the single- and double-precision integer and floating-point processing capabilities of the ARM920T processor core."
Cirrus says it supports the processor with Microsoft's Windows CE .NET operating system, "optimized and fully supported by an in-house Cirrus Logic software development and support team."

"The EP9302 gives system designers an unbeatable combination of raw power and on-board Ethernet at a price far less than competing IC or reference design solutions," said Tom Lee, Cirrus's VP of embedded products marketing.
The EP9302 will be available in June, 2004 in a 208-pin quad flat package, priced at $9.96 in volumes of 10,000+. Cirrus Logic's line-up of currently available Nine-Series (ARM9 core based) embedded processors includes the EP9301, EP9312, and the flagship EP9315, a very highly integrated chip containing an ARM920T processor, graphics engine, a 2D graphics accelerator, IDE interface, Ethernet, USB, PCMCIA, and the graphics and audio capabilities needed for a sophisticated user interface, according to Cirrus.
