Skyworks CX80503-34 Cx805-30 baseband processor for multiband gsm and gprs application Datasheet

PRODUCT SUMMARY
CX805-30 Baseband Processor
for Multiband GSM and GPRS Applications
Applications
Description
• GSM handsets and modules (850/900/1800/1900 MHz)
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.
• GPRS handsets and modules (850/900/1800/1900 MHz)
• Bluetooth®-enabled wireless headset modules
Features
• 0.25µ CMOS process technology
• ARM7 TDMI core
• Skyworks DSP core with all memory on-chip
• GPRS class 10 and circuit-switched data (14.4 kbps) services
• Half-rate, full-rate, and enhanced full-rate speech coders
• Voice features such as voice recognition, conversation record,
and voice memo
• Hardware accelerator for GPRS encryption algorithms (GEA 1
and 2)
• Integrated Real-Time Clock (RTC)
• Interface to handset MMI peripherals such as keypad, liquid
crystal display (LCD), and annunciator
• Interfaces to Skyworks IA and PMIC devices
• Interface to Subscriber Identity Module (SIM)
• Addresses up to 16 MB of external memory (flash or SRAM)
• Application Interfaces:
— Serial/RS-232
— Infra-red Data Adapter (IrDA)
• Low power operation. 3 V I/Os and an on-chip supplied 2.5 V
core
• Eight Chip Select (CS) signals for external memory
• 16-bit data bus, 24-bit address bus
Skyworks offers this part as a lead (Pb)-free
“environmentally friendly” package that is RoHS
compliant (European Parliament for the Restriction of
Hazardous Substances).
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
