The EP9312 SoC contains a 200MHz ARM920T processor core along with Cirrus's "MaverickCrunch" coprocessor engine. Other on-chip functions include controllers for 1/10/100 Mbps Ethernet, SPI and IS audio, CRT/LCD graphics, EIDE, keypad, touchscreen, IrDA, three USB 2.0(12 Mbps) host ports, and three UARTs.
Cirrus Logic EP9312 SoC Block DiagramCirrus's EDB9312 board kit includes both the Windows CE .NET 4.2 BSP and an evaluation version of Microsoft's Platform Builder. The EDB9312 BSP includes the Windows CE .NET 4.2 operating system with on-chip driver support for functions such as Ethernet, IDE, USB, and accelerated 2D graphics. The porting and driver development work was performed by the Cirrus Logic system software development team.
Cirrus says it plans to obtain Windows CE .NET certification across its entire family of ARM9-based EP93XX embedded processors, including the recently introduced "flagship" EP9315 processor and EP9301 processor.
"Cirrus Logic is a system solution provider, not just a chip supplier," commented Tom Lee, vice president, Embedded Processor Marketing. "We are now supplying the entire embedded system solution platform, including a highly integrated ARM9-based SOC, a hardware development platform, a comprehensive tool chain and the latest Windows CE operating system."
