LE25W81QE Serial Flash Memory 8 Mb (1024K x 8) Overview The LE25W81QE is a serial interface-compatible flash memory device www.onsemi.com with a 1M 8-bit configuration. It uses a single 2.6 V power supply for both reading and writing (program and erase functions) and does not require a special power supply. As such, it can support on-board programming. It has three erase functions, each of which corresponds to the size of the memory area in which the data is to be erased at one time: the small sector (4K bytes) erase function, the sector (64K bytes) erase function, and the chip erase function (for erasing all the data together). The memory space can be efficiently utilized by selecting one of these functions depending on the application. A page program method is supported for data writing. The page program method of LE25W81QE can program any amount of data from 1 to 256 bytes. This IC incorporates ON VDFN8 5x6, 1.27P / VSON8T (6x5) Semiconductors unique high-speed programming function which enables fast 0.3 ms (typ) page program time. The program time of 1.5 s (typ) when programming 8M bit full-memory space makes for fast data writing when the chip erase function is used. While making the most of the features inherent to a serial flash memory device, the LE25W81QE is housed in an 8-pin ultra-miniature package. Serial flash memory devices tend to be at a disadvantage in terms of their read speed, but the LE25W81QE has maximally eliminated this speed- related disadvantage by supporting clocks with frequencies up to 50 MHz under SPI bus specifications. All these features make this device ideally suited to storing program codes in applications such as portable information devices and small disk systems, which are required to have increasingly more compact dimensions.
