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 Man-
Machine 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

• 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 provides a block diagram of the CX805-30 device in a
typical application. Package dimensions are provided in Figure 2
for the 12 x 12 devices and Figure 3 for the 10 x 10 devices.
