Overview: Ordering number : EN*A1066A LE25FU406B
Overview CMOS IC 4M-bit (512K×8) Serial Flash Memory The LE25FU406B is a serial interface-patible flash memory device with a 512K × 8-bit configuration. It uses a single 2.5V 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 the LE25FU406B can program any amount of data from 1 to 256 bytes. The program time of 2.0ms (typ.) when programming 256 bytes (1 page) at one time makes for fast data writing.
