Microchip Technology Introduces World's Fastest 256K I2C Serial EEPROM Devices.CHANDLER, Ariz.--(BUSINESS WIRE)--Feb. 16, 1998--Microchip Technology Inc. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :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 ) Monday debuted the world's fastest 256K I2C I2C Inter-Integrated Circuit I2C Intelligent Interface Controller I2C Intelligent Controller (TM) 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. devices, the 24LC256 and 24AA256. "These devices offer write cycle time that, at less than 5 ms, is twice as fast as typical 64K - 256K array I2C(TM) serial EEPROM devices," said Art Eck, product marketing manager, Microchip's Memory & Specialty Products Division. "The faster write cycle helps protect critical data during brownout A lowering of AC power voltage for some period of time. Brownouts can be very harmful to electronic equipment if sustained for long periods. Brownouts can cause flickering or a dimming on screen, and the computer may experience intermittent problems as a result. See blackout. . The devices also fill the need for a nonvolatile, byte-alterable memory array to store large amounts of data." With read current below 400 microamps, typical standby current below 100 nA and operating voltage down to 1.8 volts over the industrial temperature range, the new Microchip devices are ideal for battery operation. Applications for the device include cellular and cordless phones and pagers as well as some industrial applications such as power meters. The 24LC256 (voltage of 2.5V and up) and 24AA256 (voltage of 1.8V and up) are available in the PDIP (Plastic DIP) See DIP. and 208 mil SOIC (Small Outline IC) A small-dimension, plastic, rectangular, surface mount chip package that uses gull-wing pins extending outward. See gull-wing lead, SOJ and chip package. packages. The 24LC256 in PDIP packaging is $2.98 in 1,000-unit quantities. The 208 mil SOIC package is $3.13 in 1,000-unit quantities. Volume shipments are available immediately. Contact any Microchip sales representative or authorized distributor worldwide for more information. Microchip has recently introduced other innovative non-volatile memory products, including the 24XX128 family, the industry's smallest footprint area and lowest profile packages for a 128K bit I2C(TM) serial EEPROM, and the 24XX64 family, the world's smallest 64K serial EEPROMs. Microchip was first to introduce a 64K serial EEPROM and was first to introduce a 64K in an 8-lead TSSOP TSSOP Thin Shrink Small Outline Package TSSOP Thin Scale Small Outline Package . Microchip supports all its memory devices through the Serial EEPROM Designer's Kit, a development system that allows designers to quickly develop a robust and reliable serial EEPROM-based design and significantly reduce the time required for system integration and hardware/software debug. Two critical components of the kit are the Total Endurance(TM) Software Model (Version 3.0) and the SEEVAL(TM) Serial EEPROM Evaluation and Programming System. Microchip Technology Inc. manufacturers the PICmicro(TM) family of 8-bit RISC-based microcontrollers -- with OTP, Enhanced FLASH, EEPROM and ROM memory technologies; serial EEPROMs and related specialty memory products; and KEELOQ(R) code hopping devices. These products target thousands of embedded control applications in the consumer, automotive, office automation, communications and industrial markets. Microchip's quality systems are ISO (1) See ISO speed. (2) (International Organization for Standardization, Geneva, Switzerland, www.iso.ch) An organization that sets international standards, founded in 1946. The U.S. member body is ANSI. 9001 certified. Headquartered near Phoenix in Chandler, Microchip employs approximately 2,200 people worldwide and has sales offices throughout Asia, Europe, Japan and North America. -0- NOTE TO EDITORS: The Microchip name and logo, PIC, and KEELOQ are registered trademarks of Microchip Technology Inc. in the United States and other countries.
