Overview
a Baseband Processor for TD-HSDPA TD-SCDMA and GSM/GPRS/EGPRS Handsets and Data Modems Preliminary Technical Data AD6905 INTRODUCTION The AD6905 is an advanced, low power baseband processor that meets the demanding requirements of TD-HSDPA and GSM/GPRS/EGPRS terminals with advanced system power management and multimedia capabilities.
The chip integrates a powerful Blackfin® DSP processor along with an ARM926EJS® microcontroller and an extensive set of peripheral interfaces that support features such as a digital camera sensor, USB OTG, Multimedia Card, SD (Secure Digital) Card, IrDA, thumbwheel, color displays, and other peripheral devices such as Bluetooth, WiLAN, and A-GPS modules.
With integrated 3G/TDD hardware acceleration to support High Speed Downlink Packet Access (TD-HSDPA) at data rates up to 2.
8Mbps, the AD6905 enables new levels of wireless connectivity.
FEATURES MCU Control Processor Subsystem 32-bit ARM926EJ-S® MCU Control Processor 260 MHz operation at 1.
5V 16KB instruction cache 16KB data cache 4kB Instruction Tightly Coupled Memory (TCM) 2-Mbit On-chip System SRAM Ciphering coprocessor supporting GEA1 and GEA2 and GEA3 encryption algorithms Dedicated multi-channel DMA controller DSP Subsystem Blackfin 16-bit fixed-point DSP Processor 260 MHz operation at 1.
5V Memory: ƒ L1 program space: 64 kB SRAM and 16 kB configurable as instruction cache or SRAM ƒ L1 data space: Two banks of 16K bytes, each with 8K bytes of dedicated SRAM and an additional 8K bytes that can be configured as either cache or SRAM ƒ L2 space: 64KB SRAM Ciphering coprocessor supporting A5/1, A5/2, A5/3, GEA1, GEA2, GEA3, f8 and f9 ciphering algorithms Dedicated multi-channel DMA controller Hardware acceleration for TD-SCDMA 384kbps and TD-HSDPA up to 2.
8Mbps Peripherals Subsystem Support for Burst-mode, Page-mode, and NAND Flash memory Support for SRAM, SDRAM, and PSRAM (CellularRAM) Full-Speed USB 2.
