Overview
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.
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 smallscale rewriting.
Features • Read/write operations enabled by single 3.
0V power supply: 2.
7 to 3.
6V supply voltage range • Operating frequency : 30MHz • Temperature range : 0 to 70°C • Serial interface : SPI mode 0, mode 3 supported • Sector size : 256 bytes/page sector, 64K bytes/sector • Page erase, sector erase, chip erase functions • Page program function (1 to 256 bytes/page), Page write function (1 to 256 bytes/page) • Hardware protect function (lower 256 pages) • Hardware reset function Continued on next page.
