LSI Logic Delivers System-on-a-Chip Expertise With CDMA Baseband Processor
MILPITAS, Calif., Feb. 8 /PRNewswire/ -- System-on-a-chip
leader LSI Logic Corporation (NYSE: LSI) today announced
delivery of its single-chip Code Division Multiple Access (CDMA)
IS-95B baseband processor, which is targeted for use in
IS-95B-compliant wireless devices such as handsets for the cellular
and PCS bands.
LSI Logic's CDMA Baseband Processor, or CBP, integrates an
ARM7 TDMI microprocessor, two OAKDSPCore(R) digital signal
processors (DSPs), mixed-signal circuitry and standard cell logic to
include all baseband processing logic in a single chip. The CBP is
also the ideal platform for use in wireless communicators,
dual-mode phones, wireless modems and other portable hand-held
devices where printed circuit board size, power and cost are critical
to the success of the end system.
Developed using LSI Logic's G11TM 0.18-micron (Leff) 1.8 volt
CMOS technology and the CoreWare(R) design program, the single
chip CBP device decreases power consumption by nearly 60 percent
over conventional industry offerings.
"LSI Logic's CDMA baseband processor comes to the handset
market at an ideal time," said Giuseppe Staffaroni, vice president
and general manager of the Communication Products division at LSI
Logic. "Our single chip baseband processor sets a new standard for
the wireless industry with its low power, functional integration and
flexibility; it brings to handset manufacturers a very competitive,
cost effective standard-product platform from which to design their
next generation CDMA handsets. Also, the baseband processor
enables manufacturers to compete successfully with other mobile
cellular standards deployed throughout the world."
"Production of CDMA handsets will grow from 8.7 million units
produced in 1997 to 69 million units produced in 2002," said Dale
Ford, principal analyst of semiconductor application markets at
Dataquest. "Delivery of the single-chip CDMA baseband processor
to the market by LSI Logic comes at a time when handset
manufacturers are selecting silicon suppliers for their
next-generation phones."
In addition to the embedded processors and special peripheral logic,
the CBP integrates DSP memory in the form of RAM and ROM for
multiple vocoders (EVRC, and 8- and 13-Kbps QCELP), and all the
mixed-signal cores to implement the voice codec, the baseband
analog transmit and receive paths, auxiliary ADCs and DACs, and
PLL in a single chip. This level of integration is important to
designers because it provides maximum processing capability while
minimizing power consumption and cost when designing CDMA
handsets.
As handset manufacturers rapidly transition to support wireless data
services, the CBP architecture has been engineered to support the
IS-95B, 115.2-kbps, high-speed data rate. This provides the
handset manufacturer with the ability to differentiate products based
on optional features and services while maintaining a common
platform of design. The CBP provides three fully programmable
UARTS, each capable of the full 115.2-kbps data rate, enabling
customers to take full advantage of current and future data
application requirements.
The CBP uses sophisticated onboard hardware accelerators to
reduce power consumption required by repetitive DSP tasks.' This
means CDMA solutions using the CBP device consume
significantly less power during conversation, receive-only and idle
modes. The CBP achieves these dramatic improvements by a
combination of feature integration, system architecture, optimized
processing algorithms and silicon technology. By combining the
complete baseband functionality on a single chip, LSI Logic's CBP
eliminates the power consumed by inter-pin capacitance -- a
common problem associated with multi-chip solutions. LSI Logic's
G11 silicon process allows the CBP's digital circuitry to operate at a
low 1.8 volts, and together with leveraging the proprietary circuits,
enables the device to achieve a new level of power conservation
available nowhere else in the industry.
The CBP's companion software for its DSP and microcontroller
provides the LSI Logic device with unprecedented programmability.
This programmability minimizes risk while speeding time-to-market
by allowing handset designers to customize and field-test the design
in a RAM-based, single-chip architecture. This flexibility enables
the integration and validation of specialized product features into the
device before volume production commences in a pin-and-package
compatible, ROM-based chip.
A CBP Development System, or CDS, supports the CBP device
and is a powerful engineering and development environment that
offers designers a complete CDMA development and debugging
platform. The development system allows access to all of the
relevant system interfaces for convenient software engineering.
Both the CDS and CBP are supported with Layer 2 and 3 protocol
stack software from Isotel Research Ltd. The CBP and CDS have
been designed to also operate with a customers' own protocol stack,
if necessary. In addition to a complete set of infrastructure software
tools and programs, the CBP and CDS are complemented by LSI
Logic's unique Engineering Test System (ETS) software. The ETS
package provides a complete and configurable test monitoring
environment that gives real-time diagnostic capability and forms the
basis for production and support testing.
Implemented in a 208 miniBGA package measuring 17mm x 17mm,
the CBP also can be made available to customers in a 16mm x
16mm, 280-pin Chip Scale (CSP) package. The CBP is sampling
now, priced at less than $30 in volume quantities, and ready for
customer production through the company's world-class 8-inch
wafer fabrication facility in Gresham, Ore.
The Communication Products Division provides leading
silicon-based solutions for customers participating in LSI Logic's
Wireless and Telecommunications vertical market. In 1998, the
division delivered the industry's first programmable single-chip
GSM Baseband Processor and announced a programmable
single-chip CDMA Baseband Processor architecture for wireless
handsets. The division also provides enabling technology for the
development of 3rd generation wireless products.
The CTIA Wireless '99 Show will run from February 8-10 at the
Ernest Morial Convention Center in New Orleans. LSI will
demonstrate the CBP in booth 6133.
