DescriptionThe EP9301, an attractively priced ARM9 processor, has a high-performance design that is ideal for many entry-level consumer and industrial electronic products.
The EP9301 features an advanced 166 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 EP9301 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.
MaverickKey? unique hardware programmed IDs EP9301 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, AC '97 and I2S audio. A two-port USB 2.0 Full Speed host (OHCI), running at 12 Mbps, two UARTs and an analog voltage-measurement analog-to-digital (A/D) converter are included as well.
The ARM920T core operates from a 1.8 V supply, and the input/output (I/O) operates at 3.3 V with power usage between 100 mW and 675 mW (depending on speed).
Designers of industrial controls, internet radios, digital media servers and jukeboxes, thin clients, set-top boxes, point-of-sale terminals, biometric security systems and GPS devices will benefit from the EP9301's integrated architecture and advanced features. In fact, with its broad range of peripheral interfaces, the EP9301 is suited to an even more high-volume applications. By enabling or disabling the EP9301'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 EP9301 are complemented by a range of complete operating systems. Both Microsoft? Windows CE.NET? and Linux? solutions are available with total driver support.
