EP7309 Product details

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 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®.

FEATURES
■ 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.)
■ Dynamically programmable clock speeds of 18, 36, 49, and 74 MHz
■ 48 KB of on-chip SRAM
■ MaverickKey™ IDs
    — 32-bit unique ID can be used for SDMI compliance
    — 128-bit random ID
■ LCD controller
    — Interfaces directly to a single-scan panel monochrome STN LCD
    — Interfaces to a single-scan panel color STN LCD with minimal external glue logic
■ Full JTAG boundary scan and Embedded ICE support
■ Integrated Peripheral Interfaces
    — 8/32/16-bit SRAM/FLASH/ROM Interface
    — Digital Audio Interface providing glueless interface to low-power DACs, ADCs and CODECs
    — Two Synchronous Serial Interfaces (SSI1, SSI2)
    — CODEC Sound Interface
    — 8×8 Keypad Scanner
    — 27 General Purpose Input/Output pins
    — Dedicated LED flasher pin from the RTC
■ Internal Peripherals
    — Two 16550 compatible UARTs
    — IrDA Interface
    — Two PWM Interfaces
    — Real-time Clock
    — Two general purpose 16-bit timers
    — Interrupt Controller
    — Boot ROM
■ Package
    — 208-Pin LQFP
    — 256-Ball PBGA
    — 204-Ball TFBGA
■ The fully static EP7309 is optimized for low power dissipation and is fabricated on a 0.25 micron CMOS process
