ARM9, System-on-Chip Processor with Integrated IDE EP9312
The EP9312 is an ARM920T-based system-on-chip that paves the way for next-generation consumer and industrial electronic products. The agile performance provided by the 200 MHz ARM920T processor and the breadth of peripheral interfaces, including an integrated IDE interface, suit the EP9312 for a broad range of applications. The ARM920T microprocessor core with separate 16 KB, 64-way, set-associative instruction and data caches is augmented by the MaverickCrunch™ coprocessor. The EP9312's MaverickCrunch engine is an advanced mixed-mode math coprocessor that greatly accelerates the single- and double-precision integer and floating-point processing capabilities of the ARM core.With the EP9312's built-in IDE interface, the processor can connect directly with multiple hardware devices such as hard drives, CD drives and DVD drives. This significantly reduces BOM costs and board size.The MaverickKey™ unique hardware programmed IDs are a solution to the growing concern over secure Web content and commerce. With Internet security playing an important role in the delivery of digital media such as books and music, traditional software methods are quickly becoming unreliable. The MaverickKey unique IDs provide OEMs with a method of using specific hardware IDs such as those assigned for SDMI (Secure Digital Music Initiative) or other digital rights management authentication mechanisms.A high-performance 1/10/100 Mbps Ethernet media access controller is included in the EP9312 along with external interfaces to SPI and I²S audio, Raster/LCD, IDE storage peripherals, keypad and touchscreen. The EP9312 integrates three USB 2.0 full speed (12 Mbps) host ports, and three UARTs are included as well.The ARM920T's 32-bit microcontroller architecture, with a five-stage pipeline, delivers impressive performance at very low power. The ARM core operates from a 1.8 V supply, while the input/output operates at 3.3 V. The EP9312's power consumption is typically less than 0.5 W. The EP9312 can be used for a variety of applications: digital media servers and jukeboxes, telematic control systems, networked attached servers, thin clients, set-top boxes, point-of-sale terminals, industrial controls, biometric security systems, GPS devices and more.Cirrus Logic's embedded processor products are complemented by a range of complete operating systems.
