LE25FW403A ^{4M-bit (512K×8) Serial Flash Memory}
30MHz SPI Bus
Overview
The LE25FW403A is an onboard programmable flash memory device with a 512K×8-bit configuration. It uses a single
3.0V power supply and supports the serial interface. It has three erase functions depending on the size of memory area in
which the data is to be erased: the chip erase function, the sector (64K bytes) erase function, and a page (256 bytes) erase
function. A page program method is supported for data writing and it can program any amount of data from 1 to 256
bytes. The page program time depends on the number of bytes programmed and the IC provides a high-speed program
time of 1.5ms (typ) when programming 256 bytes at one time. Moreover, equipped with a page write function that allows
anywhere from 1 to 256 bytes of data in a page to be rewritten, this device is optimal for applications that perform small-
scale rewriting.
