IntelliCeiver™ technology and PA bypassing
1.1.1 QSC6055 Features
■ Modem microprocessor – a low-power, high-performance RISC microprocessor core
running at 192 MHz and featuring the ARM926EJ-S™ CPU and Jazelle™ accelerator
circuit from ARM® Limited.
■ Modem digital signal processor (mDSP) – the low-power, high-performance
QDSP4u8™ targeting 85 MHz.
■ Application digital signal processor (aDSP) – the low-power, high-performance
QDSP4u8™ targeting 115 MHz.
■ 96 MHz bus clock for 16-bit DDR SDRAM and 16/32-bit PSRAM
■ Dual-memory buses separating the high-speed memory subsystem (EBI1) from
low-speed peripherals (EBI2), such as LCD panels
■ 1.8 V memory interface support on EBI1
■ 1.8 V or 2.6 V memory interface support on EBI2
■ Memory types supported:
❒ 16-bit NOR flash (burst mode), including multiplexed address/data types
❒ 8-bit and 16-bit NAND flash and 16-bit OneNAND
❒ 16-bit DDR SDRAM
❒ 16-bit and 32-bit PSRAM requiring multiplexed address/data types
■ Bootup is supported from the following devices:
❒ Burst NOR on EBI1
❒ Any supported NAND memory type on EBI2

■ Enhanced GPS position location
❒ Integrated gpsOne functionality, featuring enhancements by SnapTrack®, Inc., to
enable a wide variety of location-based services and applications, including points
of interest, personal navigation, and friend finder
❒ Simultaneous-GPS (processes GPS on its Rx path while CDMA signals continue
to be processed on a separate Rx path)
❒ 1024x searcher, DFT accelerator, off-chip RAM for measured data storage
■ Two universal asynchronous receiver transmitter (UART) serial ports
