Microchip Technology Debuts First 512 Kbit I2C(TM) Compatible Serial EEPROM In Low-Profile DFN Package

CHANDLER, Ariz., March 5, 2003 [NASDAQ: MCHP - Microchip Technology Inc. today announced an industry first by offering a 512 Kbit I2C(tm) compatible serial EEPROM in an 8-pad dual flat no-lead (DFN) package. The 24LC512, 24AA512, and 24FC512 are implemented in the company's advanced PMOS Electrically Erasable Cell (PEEC) process technology, enabling Microchip to offer high-density, low-power EEPROM devices in one of the thinnest packages available (0.9mm).

The 6mm x 5mm DFN package enables designers to use a 512 Kbit serial EEPROM in low-headroom applications while reducing cost and increasing available board space. Users currently utilizing Microchip's 128 Kbit or 256 Kbit EEPROM memory devices now have the option to design in a higher-density EEPROM while retaining the same footprint. Additional packages include an 8-lead PDIP, 8-lead SOIC and 14-pin TSSOP.

Microchip's PEEC cell represents its newest and most advanced generation in a long history of EEPROM innovation, quality and features. In addition to shrinking high-density devices into tiny packages, the process maintains Microchip's leadership in quality and reliability: more than 200 years data retention and 1,000,000 Erase/Write cycles at 85C.

Each of the three devices has a page-write capability of up to 128 bytes and is capable of random reads throughout the entire array. Functional address lines allow up to eight devices on the same bus for a maximum of 4 megabits total address space. Additional features include a fast write time of 5 milliseconds, a clock rate of 400 KHz throughout the operating voltage of 2.5V-5.5V and temperature range of -40C to +85C. A high-speed version of this chip, the 24FC512, is capable of operating at a bus speed of 1 MHz over the same voltage and temperature range. The low-voltage version (24AA512) operates between 1.8V-5.5V, making it ideal for battery-powered applications.

The 24LC512 targets advanced, low-power applications including cell phones, caller ID, set-top boxes, pagers, Bluetooth(tm) technology or wireless accessories, consumer electronics, ISO cards and data acquisition systems. Each of these markets requires high-density, compact, non-volatile memory for data storage.

Pricing in 10,000-unit quantities is $1.83 each for the 24LC512 and 24AA512 devices and $1.88 for the 24FC512. Samples and volume production are available now. For more information contact any Microchip sales representative or authorized worldwide distributor or visit
