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.Business Editors/High-Tech Writers CHANDLER, Ariz.--(BUSINESS WIRE)--Feb. 14, 2001 Microchip Technology Inc. (Nasdaq: MCHP MCHP Maryland Children's Health Program MCHP Microchip Technologies (stock symbol) MCHP Micro-sized Combined Heat and Power (American Honda Motor Co. & Climate Energy, LLC) MCHP Maine Community Heritage Project ) Wednesday introduced the world's first serial EEPROM (Electrically Erasable Programmable ROM) A rewritable memory chip that holds its content without power. Although EEPROMs spawned flash memory, EEPROMs are byte addressable at the write level, whereas flash chips must erase a block of bytes before rewriting. supporting the Advanced Communications Riser The Advanced Communications Riser, or ACR, is a form factor and technical specification for PC motherboard expansion slots. It is meant as a supplement to PCI slots, a replacement for Audio/modem_riser (AMR Special Interest Group (ACR See riser card. SIG) specification, providing the enumeration memory for next-generation PC Audio Modem Riser See riser card. 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 specification as a custom 8K I2C(TM) 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 See DSL. (communications, protocol) Digital Subscriber Line - (DSL, or Digital Subscriber Loop, xDSL - see below) A family of digital telecommunications protocols designed to allow high speed data communication over the existing copper telephone lines between end-users and (DSL), audio technologies and future wireless bus technologies. 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 (Dual In-Line Memory Module) A printed circuit board that holds memory chips and plugs into a DIMM socket on the motherboard. See memory module. DIMM - Dual In-Line Memory Module 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 See VESA DDC. (TM)1/DDC(TM)2-compatible solutions, including the popular 24LC21 and 24LCS21A. For board identification, the 24LCS61 provides software address capability of up to 255 devices on the same bus, eliminating I2C 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.
