Product Summary
The EP7309-CV 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 EP7309-CV is built around an ARM720T processor with 8 KB of fourway set-associative unified cache and a write buffer.
Applications of the EP7309-CV include: Software adjustable flash period and duty cycle, Operates from 32 kHz RTC clock,
Will continue to flash in IDLE and STANDBY states, 4 mA drive current.
Parametrics
EP7309-CV absolute maximum ratings: (1) DC Core, PLL, and RTC Supply Voltage: 2.9V; (2) DC I/O Supply Voltage (Pad Ring): 3.6V; (3) DC Pad Input Current: ±10 mA/pin; ±100 mA cumulative; (4) Storage Temperature, No Power: –40°C to +125°C.
Features
EP7309-CV features: (1) ARM720T Processor: ARM7TDMI CPU, 8 KB of four-way set-associative cache, MMU with 64-entry TLB, Thumb code support enabled; (2) Ultra low power: 90 mW at 74 MHz typical, 30 mW at 18 MHz typical, 10 mW in the Idle State, <1mW in the Standby State; (3) Advanced audio decoder/decompression capability: aupports bit streams with adaptive bit rates, allows for support of multiple audio decompression algorithms (MP3, WMA, AAC, ADPCM, Audible, etc.) .
