PMC-Sierra NasdaqPMCS is a fabless semiconductor company which develops and sells devices into the communications, storage, printing, and embedded computing marketplaces.

Corporate history

Sierra Semiconductor was originally founded in 1984 in San Jose, California, and went public in 1991. It received funding on 1/11/1984 from Sequoia Capital.

Pacific Microelectronics Centre (Burnaby, British Columbia, Canada) was spun off from Microtel Pacific Research (the research arm of BC TEL at the time) to develop ATM and later SONET chips. With investment from Sierra Semiconductor, PMC was established in 1992 as a private company focused on providing networking semiconductors, and became a wholly owned, independently-operated subsidiary of Sierra Semiconductor in 1994. Microtel is currently a part of Verizon.

In August 1996, Sierra Semiconductor announced its decision to exit the personal computer modem chipset business, to restructure its other non-networking products and focus on its networking products. In 1997, the Company changed its name to PMC-Sierra to reflect the corporate focus on internetworking semiconductor solutions.

In 2001, PMC-Sierra was named "Semiconductor Supplier of the Year" by Cisco Systems and has received numerous other similar awards. PMC's CEO is Robert L. "Bob" Bailey.

As of 2007, the company employs over 1000 people and sells telecommunication, PON, storage and embedded microprocessor silicon solutions. It has design centers in 2 cities in Canada, 3 cities in the U.S., Israel, India, and China. It also has sales offices throughout the world and is a member of the Russell 2000 index.

PMC-Sierra technology history

During the Sierra Semiconductor period in the 1980's and early 1990's, Sierra was the leading maker of Switched-capacitor filter based modems and also developed ASICs which combined processors and EEPROM. Sierra was the world leader in the 2400 and 4800 bps modem generations.

Pacific Microelectronics Centre (PMC) was a co-founder of the SATURN Development Group in 1992. PMC and PMC-Sierra produced a product line of communications devices in the "S/UNI" family to SATURN's PL-2, PL-3, and PL-4 specifications.

PMC-Sierra's other notable communications products include the TEMUX PDH multiplexer, the CHESS series SONET/SDH switches, and the AAL1gator Circuit Emulation Service device. They had the most complete product line of wireline communications ASSPs in the late 1990's and early 2000's.

PMC-Sierra, through its QED acquisition was a leader in MIPS microprocessors in the early 2000's. Its product line ranged from the RM5000 and RM7000 family of stand-alone microprocessors to the RM9000GL and RM9150 integrated System-On-a-Chip processors.
