Digital ICs/DSPs: 128-Mbit Flash Memory Pushes Data Transfers To 108 MHz

July 5, 2004

As cell phones and other portable systems deal with larger files that hold images and other graphic content, faster data-transfer times are needed for the nonvolatile storage devices. The LH28F128BN is a 1.8-V, 128-Mbit flash storage device that can deliver data at rates of 108 MHz when operating in its synchronous burst mode. In standard random-access mode, the memory has an access time of 60 or 70 ns and a page mode access time of 20 or 25 ns. Available in an 8-Mword by 16-bit organization, the LH28F128BN can operate over a 1.7- to 1.9-V supply range. Readout current is 15 mA when operating at 5 MHz in its asynchronous mode. The flash memory comes in an 8- by 11-mm fine-pitch BGA package. In lots of 100,000 units, the device sells for $11 apiece. Production quantities are immediately available.
