仕様・特性

EP7309 Data Sheet FEATURES High-performance, Low-power, System-on-chip with Enhanced Digital Audio Interface ■ ARM720T Processor — ARM7TDMI CPU — 8 KB of four-way set-associative cache — MMU with 64-entry TLB — Thumb code support enabled ■ Ultra low power — 90 mW at 74 MHz typical — 30 mW at 18 MHz typical — 10 mW in the Idle State — <1 mW in the Standby State ■ Advanced audio decoder/decompression capability — Supports bit streams with adaptive bit rates — Allows for support of multiple audio decompression algorithms (MP3, WMA, AAC, ADPCM, Audible, etc.) OVERVIEW 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 corelogic functionality of the device is built around an ARM720T processor 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®. (cont.) (cont.)
