EP9315

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.

The 16 KB instruction cache and 16 KB data cache provide zero-cycle latency to the current program and data, or they can be locked to guarantee no-latency access to critical instructions and data. For applications with instruction-memory size restrictions, the ARM920T's compressed Thumb instruction set provides space efficiency and maximum external instruction memory usage.

The ARM920T core is augmented by the MaverickCrunch™ coprocessor. This coprocessor greatly accelerates the ARM920T's single- and double-precision integer and floating-point processing capabilities.

With the EP9315's built-in IDE interface, the processor can connect directly with multiple hardware devides such as hard drives, CD drives and DVD drives. This significantly reduces BOM costs and board size.

The EP9315's user interface capabilities include a 2-D graphics accelerator that improves performance by handling block copy, block fill, line draw and bit blit. Resolutions of up to 1024 x 768 (XGA) are supported. Touchscreen, keypad and high quality sound (SPI, I²S, and AC '97) complete the EP9307's strong user interface features.

MaverickKey™ unique hardware programmed IDs provide a solution to concerns over secure Web content and commerce. MaverickKey provides OEMs with a method of assigning specific hardware IDs such as those used for SDMI (Secure Digital Music Initiative) or any other digital rights management mechanisms.

A high-performance 1/10/100 Mbps Ethernet media access controller (MAC) is included, along with external interfaces to SPI, I²S audio, Raster/LCD, IDE storage peripherals, keypad, and touchscreen. A three-port USB 2.0 full-speed host (OHCI), running at 12 Mbps, and three UARTs are included as well.

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 an 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.
