LE25FW808 ^{8M-bit (1024K×8) Serial Flash Memory}
with High-Density Read Mode
Overview
The LE25FW808 is 1024K×8bit Serial flash memory by 3.0V single power supply operation, and support serial
peripheral interface (S.P.I.). There are three kinds of erase functions, Small Sector (8K bytes) erase, Sector (64K bytes)
erase and Chip erase. If those erase is used properly according to the application, you can efficiently use the memory space.
Page program can program the arbitrary data from 1 byte to 256 bytes. LE25FW808 has our original high-speed program
function, page program time is 0.3ms (Typ.). Therefore, the overall rewriting time of 8M bit is 1.5s (Typ.), when
combining with Chip erase. Moreover, LE25FW808 is stored in 8 pin very small package by making the best use of the
feature of serial interface. According to these features, LE25FW808 is the best suited for applications in the portable
electronic devices, that require re-programmable nonvolatile storage of program memory.
LE25FW808 has also the High-Density read mode (hereafter, HD_READ mode) that is the most high-speed data transfer
in the world as the flash memory with serial interface. About eight times the data-transfer velocity can be achieved without
changing the clock frequency used in a usual serial flash memory by using this mode. For instance, it is possible to read
with 240Mbit/s in the maximum by using the HD_READ mode of 30MHz though a standard serial flash memory read with
30Mbit/s or less.
Features
• Read/write operations enabled by single 3.0V power supply: 2.7 to 3.6V supply voltage range
• Operating frequency : 50MHz
• Temperature range : 0 to 70°C
–40 to +85°C (Planning)
