LE25U40CMC
CMOS LSI
Serial Flash Memory, 4 Mb (512K8)
Overview
The LE25U40CMC is a SPI bus flash memory device with a 4M bit (512K
8-bit) configuration that adds a high performance Dual output and Dual
I/O function. It uses a single 2.5v power supply. While making the most of
the features inherent to a serial flash memory device, the LE25U40CMC is
housed in an 8-pin ultra-miniature package. All these features make this
device ideally suited to storing program in applications such as portable
information devices, which are required to have increasingly more compact
dimensions. The LE25U40CMC also has a small sector erase capability
which makes the device ideal for storing parameters or data that have fewer
rewrite cycles and conventional EEPROMs cannot handle due to
insufficient capacity.
