64Mb flash device with SPI

Spansion LLC is sampling a 64Mb flash device with a serial peripheral interface (SPI) for $2.50 in 10,000-unit quantities. The new S25FL064A device is based on the company's two-bit-per-cell MirrorBit technology, giving it a read speed of 50MHz for faster boot times on embedded products. This device requires a 3V (2.7V to 3.6V) power supply for both read and write functions. It consists of 128 sectors, each with 512Kb memory.

"Spansion continues to extend the benefits of MirrorBit technology into new markets, delivering a cost-effective, high-performance solution to customers who want to implement SPI," said Bob Hoard, director of marketing, SPI products, Embedded Memory Division, Spansion, in a statement. "By offering this high-density SPI product, Spansion enables a broader segment of the embedded market to take advantage of this emerging low-cost serial interface, while also bringing a trusted name and high-volume supply to customers."

SPI devices read information serially, or one bit at a time, requiring fewer connections and thus fewer pins. The interface is designed to help lower cost, simplify board layout and reduce the form factor of embedded designs. The technology is already gaining acceptance in a variety of embedded applications like optical and hard disk drives, WLAN and DSL cards and routers, PC BIOS, DVD/CD players and recorders, and other consumer electronics devices, according to the company.

The S25FL064A is housed in a 16-pin SOIC Pb-free package that is RoHS-compliant, or based on standard materials. Production volume is expected later this year.
