Ordering number : ENA1190B CMOS IC LE25FW203A Overview 2M-bit (256K×8) Serial Flash Memory 30MHz SPI Bus The LE25FW203A is an onboard programmable flash memory device with a 256K×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.
