LE25FU206
CMOS IC
2M-bit (256K×8) Serial Flash Memory
Overview
The LE25FU206 is a serial interface-compatible flash memory device with a 256K × 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 LE25FU206 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. While
making the most of the features inherent to a serial flash memory device, the LE25FU206 is housed in an 8-pin ultra-
miniature package. Serial flash memory devices tend to be at a disadvantage in terms of their read speed, but the
LE25FU206 has maximally eliminated this speed-related disadvantage by supporting clocks with frequencies up to
30MHz under SPI bus specifications. All these features make this device ideally suited to storing program codes in
applications such as portable information devices and small disk systems, which are required to have increasingly more
compact dimensions.
Features
• Read/write operations enabled by single 2.5V power supply: 2.30 to 3.60V supply voltage range
• Operating frequency : 30MHz
• Temperature range : 0 to 70°C
-40 to +85°C (at the planning stage)
