LE25FW808

Overview

The LE25FW808 is 1024K

×8bit Serial flash memory by 3.0V single power supply operation, and support serial

peripheral interface (S.P.I.). There are three kinds of erase functions, Small Sector (8K bytes) erase, Sector (64K bytes)

erase and Chip erase. If those erase is used properly according to the application, you can efficiently use the memory space.

Page program can program the arbitrary data from 1 byte to 256 bytes. LE25FW808 has our original high-speed program

function, page program time is 0.3ms (Typ.). Therefore, the overall rewriting time of 8M bit is 1.5s (Typ.), when

combining with Chip erase. Moreover, LE25FW808 is stored in 8 pin very small package by making the best use of the

feature of serial interface. According to these features, LE25FW808 is the best suited for applications in the portable

electronic devices, that require re-programmable nonvolatile storage of program memory.

LE25FW808 has also the High-Density read mode (hereafter, HD_READ mode) that is the most high-speed data transfer

in the world as the flash memory with serial interface. About eight times the data-transfer velocity can be achieved without

changing the clock frequency used in a usual serial flash memory by using this mode. For instance, it is possible to read

with 240Mbit/s in the maximum by using the HD_READ mode of 30MHz though a standard serial flash memory read with

30Mbit/s or less.
