EP7309

The Maverick™ EP7309 is designed for ultra-low-power applications such as digital music players, internet appliances, smart cellular phones or any hand-held device that features the added capability of digital audio decompression. The core-logic functionality of the device is built around an ARM720T processor with 8 KB of fourway set-associative unified cache and a write buffer. Incorporated into the ARM720T is an enhanced memory management unit (MMU) which allows for support of sophisticated operating systems like Microsoft® Windows® CE and Linux®.

The EP7309 is designed for ultra-low-power operation. Its core operates at only 2.5 V, while its I/O has an operation range of 2.5 V3.3 V. The device has three basic power states: operating, idle and standby.

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 or music, traditional software methods are quickly becoming unreliable. The MaverickKey unique IDs provide OEMs with a method of utilizing specific hardware IDs such as those assigned for SDMI (Secure Digital Music Initiative) or any other authentication mechanism.

The EP7309 integrates an interface to enable a direct connection to many low cost, low power, high quality audio converters. In particular, the DAI can directly interface with the Crystal‚ CS43L41/42/43 low-power audio DACs and the Crystal‚ CS53L32 low-power ADC. Some of these devices feature digital bass and treble boost, digital volume control and compressor-limiter functions.

Simply by adding desired memory and peripherals to the highly integrated EP7309 completes a low-power system solution. All necessary interface logic is integrated onchip.
