The EP7312 is designed for ultra-low-power applications such as portable handheld devices that require digital audio decompression capability, Internet appliances and low-power industrial controls. The core-logic functionality of the device is built around an ARM720T processor running at clock speeds up to 90 MHz and 74 MHz with 8 KB of four-way, 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 EP7312 is designed for ultra-low-power operation. Its core operates at only 2.5 V, while its input/output has an operational range of 2.5 V to 3.3 V. The device has three basic power states: operating, idle and standby. The EP7312 integrates a digital audio interface to enable a direct connection to many low-cost, high-quality audio converters from Cirrus Logic. Simply by adding the desired memory and peripherals to the highly integrated EP7312 completes a low-power system solution. All necessary interface logic is integrated on-chip. |
