EP9301 Entry-Level ARM9 System-on-Chip Processor High-Performance ARM920T Design Ideal for Broad Range of Applications E P9301 The EP9301 is one of the most attractively machines, fitness equipment, security range of high volume applications. priced ARM9 processors in the world. systems, networked camera, MP3 mixer, Furthermore, by enabling or disabling the Its high-performance design is ideal for GSM modem and VOIP will benefit from EP9301s peripheral interfaces, designers a multitude of entry-level consumer and the EP9301s integrated architecture and can reduce development costs and industrial electronic products. Designers advanced features. In fact, with amazingly accelerate time to market by creating a of Internet radios, point-of sale terminals, agile performance provided by a 166 MHz single platform that can be easily modified industrial and building controls, jukeboxes, ARM920T processor, and featuring a to deliver a variety of differentiated end telematic control systems, set-top boxes, wide breadth of peripheral interfaces, the products. biometric security systems, lottery EP9301 is well suited to an even broader EP9301 Features 166 MHz ARM920T Processor Integrated Peripheral Interfaces Internal Peripherals 16 KB data cache and 16 KB Five input A/D with 12-bit resolution Real-Time clock with software trim instruction cache 1/10/100 Mbps Ethernet MAC 12 DMA channels for data transfer MMU enabling Linux and that maximizes system performance Two-port USB 2.0 Full Speed host (OHCI) Windows CE Boot ROM Two UARTs (16550 Type), including soft 66 MHz system bus modem support Dual PLLs control all clock domains IrDA interface, slow mode Watchdog timer MaverickKey IDs for Digital Rights Management or Design IP Security SPI port Two general purpose 16-bit timers 32-bit unique ID AC97 interface General purpose 32-bit timer 128-bit random ID 2 I S interface 40-bit debug timer External Memory Options General-Purpose I/Os 16-bit SDRAM interface, up to two banks 16 enhanced GPIOs including interrupt capability 16/8-bit SRAM/Flash/ROM I/F 8 additional optional GPIOs Serial EEPROM interface multiplexed on peripherals www.cirrus.comOvERvIEw Applications High-Performance ARM920T Processor Core MaverickKey Unique ID Secures Digital Internet radios Content and OEM Designs Point-of-sale terminals The EP9301 features an advanced MaverickKey unique hardware ARM920T processor design with an MMU Industrial and building controls programmed IDs provide an excellent that supports Linux , Windows CE and Jukeboxes solution to the growing concern over many other embedded operating systems. Telematic control systems secure Web content and commerce. With The ARM920Ts 32-bit microcontroller Set-top boxes Internet security playing an important architecture, with a five-stage pipeline, Biometric security systems role in the delivery of digital media delivers impressive performance at very such as books or music, traditional Lottery machines low power. The included 16 KB instruction software methods are quickly becoming cache and 16 KB data cache provide Fitness equipment unreliable. The MaverickKey unique IDs zero-cycle latency to the current program Security systems provide OEMs with a method of utilizing and data, or can be locked to provide Networked camera specific hardware IDs for DRM (Digital guaranteed no-latency access to critical MP3 mixer Rights Management) mechanisms. instructions and data. For applications GSM modem with instruction memory size restrictions, Both a specific 32-bit ID as well as a VOIP the ARM920Ts compressed Thumb 128-bit random ID is programmed into instruction set provides a space-efficient the EP9301 through the use of laser design that maximizes external instruction probing technology. These IDs can then memory usage. be used to match secure copyrighted content with the ID of the target device Integrated Five-Input, that the EP9301 is powering, and then Multiplexed A/D Controller deliver the copyrighted information The EP9301 integrates a signed 12-bit over a secure connection. In addition, analog-to-digital converter with a secure transactions can benefit by multiplexed front-end that is controlled matching device IDs to server IDs. through a software-configured switch MaverickKey IDs can also be used by matrix. This matrix allows routing of the OEMs and design houses to protect five input signals to the A/D sample against design piracy by presetting input or to the +REF and -REF inputs. ranges for unique IDs. For more If external REF inputs are not required, information on securing your design the A/D REF inputs can be internally using MaverickKey, please contact your switched to VDD and GND allowing all Cirrus Logic sales representative. five inputs to be sampled. Reading a sampled result enables a convert command for the next sample. These capabilities are especially useful in process control and instrumentation applications as well as voltage or temperature monitoring.
