Overview

PRODUCT SUMMARY CX805-30 Baseband Processor for Multiband GSM and GPRS Applications Applications • GSM handsets and modules (850/900/1800/1900 MHz) • GPRS handsets and modules (850/900/1800/1900 MHz) • Bluetooth®-enabled wireless headset modules Description The Skyworks CX805-30 Baseband Processors (BPs) are highly integrated, dual core processors optimized for use in Global System for Mobile communications (GSM) and General Packet Radio Service (GPRS) cellular handset applications.
The CX805-30 is the baseband portion of the Skyworks GSM/GPRS System Solution.
Both the Digital Signal Processor (DSP) core and the ARM7 THUMB™ Reduced Instruction Set Computing (RISC) architecture are well suited to meet the needs of low power, high performance embedded systems such as cellular phones.
The BP operates over a range of 2.
7 V to 3.
3 V.
The baseband processing tasks are divided between the DSP and ARM7 processor cores.
The DSP core executes the physical layer (layer 1) processing functions, and the ARM microcontroller core executes the Layer 2 and Layer 3 protocol software and ManMachine Interface (MMI) functions.
The two cores communicate through a dedicated block of dual port memory.
Each of the functional blocks in the device can be individually powered down to ensure minimum current consumption in the idle or standby mode.
The CX805-30 family of devices is available in several package options: • 12 x 12 mm, 0.
8 mm pitch, 160-pin FPBGA — CX80501-31: supports up to Class 8 GPRS operation — CX80502-33/-35: supports up to Class 10 GPRS operation • 10 x 10 mm, 0.
5 mm pitch, 180-pin FPBGA — CX80501-32: supports up to Class 8 GPRS operation — CX80502-34/-36: supports up to Class 10 GPRS operation — CX80503-34: supports up to Class 10 GPRS operation and features optimized ROM code • Lead-free 10 x 10 mm, 0.
5 mm pitch, 180-pin FPBGA — CX80502-38: supports up to Class 10 GPRS operation — CX80503-38: supports up to Class 10 GPRS operation and features optimized ROM code Figure 1...
