ST adds 32-bit NOR Flash
ST Microelectronics is offering 32Mb automotive-grade (-40 to 125°C) NOR Flash devices manufactured on a 0.11-micron process. They‘re promising 64Mb devices in Q2 and 128Mbit parts by the end of the year. The low end of the ST automotive-grade NOR Flash line is 4Mb. Competitor Spansion offers MirrorBit NOR products in densities from 16Mb to 1Gb.
ST‘s 32Mbit M29W30 targets dashboard systems and multimedia, among other automotive applications. The devices can be read, programmed and erased over a 2.7V to 3.6V power supply range. Asynchronous random access time is 70ns, and typical byte or word programming time is 10µs. Data retention is guaranteed at 20 years minimum, and write endurance is 100,000 program/erase cycles per block. The chip can be organized in 8-bit or 16-bit words. Other features include independent block erase, optional Fast Programming, and a 64-bit security code.
