Microchip has announced the world's first serial EEPROM supporting the Advanced Communications Riser Special Interest Group (ACR SIG) specification.

Microchip has announced the world's first serial EEPROM supporting the Advanced Communications Riser Special Interest Group (ACR SIG) specification.

The new 24LC09 serial EEPROM provides the enumeration memory for next-generation PC audio modem riser cards by using a nonstandard address that allows the computer to automatically detect and configure riser cards with industry-standard plug-and-play capability.

Next-generation PC audio modem riser cards provide intelligent modem, audio and network capabilities in a single card, eliminating the need for multiple cards, reducing system cost and saving board space.

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 specification as a custom 8K I2C device with a 2.5-5.5V operating voltage and -40 to +85C industrial temperature range The 24LC09 is the latest in a series of serial EEPROM innovations for identification in plug-and-play systems.

Microchip already offers Plug-and-Play devices for the DIMM module market, plug-and-play video monitor applications, and plug-and-play board identification products.

Samples and volume production of the 24LC09 are expected in April 2001.

Packaging options include tape and reel or standard tubes.
