MICROCHIP TECHNOLOGY LAUNCHES
WORLD’S FIRST SERIAL EEPROM SUPPORTING ACR SIG
Non-Standard Address Device Enables
Plug-and-Play Capability for PC Audio Modem Riser Cards
CHANDLER, Ariz., Feb. 14, 2001 [NASDAQ: MCHP] — Microchip Technology Inc. today
introduced the world’s first serial EEPROM supporting the Advanced Communications Riser
Special Interest Group (ACR SIG) specification, providing the enumeration memory for next-generation PC Audio Modem Riser cards.
The new 24LC09 serial EEPROM features a non-standard address that allows a computer to automatically detect and configure riser cards for industry-standard Plug-and-Play capability. The system bios of an ACR-compatible PC can communicate with the riser card, making it completely transparent to the computer’s operating system. The 24LC09 meets the ACR SIG
2specification as a custom 8K IC; device, address of 1011xxx, 2.5V-5.5V operating voltage, and -40C to +85C industrial temperature range
The next-generation PC Audio Modem Riser cards provide intelligent modem, audio and network capabilities in a single card, eliminating the need for multiple cards and providing reduced system cost and space savings. Applications for the 24LC09 include PC Audio Modem Riser cards supporting modems, Local Area Networks (LANs), Wide Area Networks (WANs), Digital Subscriber Line (DSL), audio technologies and future wireless bus technologies.

ADD ONE – 24LC09 SERIAL EEPROM FOR ACR SIG
The 24LC09 is the latest in a series of serial EEPROM innovations for identification in Plug-and-Play systems. Microchip offers Plug-and-Play to the DIMM module market with the 24LCS52, a special function single-chip EEPROM that is available in space saving packages. For Plug-and-Play video monitor applications, Microchip offers a complete family of single-chip DDC;1/DDC;2-compatible solutions,
including the popular 24LC21 and 24LCS21A. For board identification, the 24LCS61 provides software
2address capability of up to 255 devices on the same bus, eliminating IC board limitations and allowing
flexible plug-and-play configuration of components.
Pricing for the 24LC09 serial EEPROM is $0.45 each in 1,000-unit quantities. Samples and volume production are expected in April 2001. Packaging of the device is available in tape and reel or in standard tubes. For more information, contact www.microchip.com or any Microchip sales representative
or authorized worldwide distributor.
