Overview: Ordering number : ENA1432 CMOS IC LE25FW418A
Overview 4M-bit (512K×8) Serial Flash Memory with High-Density Read Mode The LE25FW418A is 512K×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 (4K bytes) erase, Sector (64K bytes) erase and Chip erase. Page program can program the arbitrary data from 1 byte to 256 byte. Program time is high speed, 1.5ms (Typ.). Moreover, The LE25FW418A makes the best use of the feature of the serial flash memory, and is stored in 8pin very small package. The LE25FW418A is best suited for applications that require re-programmable nonvolatile storage of program memory. LE25FW418A 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 400Mbit/s in the maximum by using the HD_READ mode of 50MHz though a standard serial flash memory read with 50Mbit/s or less.
