AT&T Wireless Services, Inc. Contracts With Industry Leader

SAN DIEGO, CA-- PCSI, a wholly owned subsidiary of Cirrus Logic Inc.
(Nasdaq: CRUS), today announced it has received a multimillion dollar
contract from AT&T Wireless Services, Inc. for the development and supply
of base stations for the newly announced narrowband PCS technology, pACT
(personal air communications technology). pACT was co-developed by AT&T
Wireless Services, PCSI and others for next generation two-way messaging
applications.

PCSI has earned a reputation as an international leader in the design,
development and supply of high performance base stations. The company's
efforts have resulted in infrastructure equipment that provides better
outdoor range and improved performance within buildings. For example,
PCSI's expertise in base station technology is evident in the Japanese
Personal Handyphone System (PHS) and Cellular Digital Packet Data (CDPD)
networks. This leading position factored heavily in AT&T's decision to
award PCSI this contract.

"The development of infrastructure is critical to facilitating the rapid
deployment of pACT to new mass markets," said Ken Arneson, vice president
of business development for AT&T Wireless Services, Messaging Division.
"As such, we again teamed with PCSI, who has delivered well on its CDPD
commitments to us. pACT represents an exciting opportunity for us, and
we're pleased that PCSI will play a significant role in bringing to market
the benefits pACT has to offer."

"We believe that pACT has broad applicability in both domestic and foreign
mass markets," said Michael Lubin, executive vice president of PCSI. "pACT
will initiate a new era of personal digital messaging and wireless
telemetry in the US and other countries. It is especially well-suited for
countries with limited deployment of telephony infrastructure. pACT is yet
another area where PCSI is demonstrating leadership in communications and
wireless computing to help enable new markets."

Since its inception in 1987, PCSI has continually demonstrated a leadership
role in furthering the development of technologies and products for
emerging markets. For example, in addition to being a key contributor to
the CDPD wireless data standard, PCSI was chosen as the contractor for the
first field trials of CDPD, supplying both infrastructure and subscriber
products. Today, PCSI is the leading provider of CDPD base stations,
having shipped more than 3500 units.

As part of the company's on-going efforts to enable new markets, Lubin went
on to state that PCSI intends to develop feature-rich, user-friendly
subscriber products and modules supporting pACT for original equipment
manufacturers (OEMs) and carriers.
