Overview
The LE25U20AQG is a serial interface-compatible flash memory device
with a 256K  8-bit configuration. It uses a single 2.5V power supply.
While making the most of the features inherent to a serial flash memory
device, the LE25U20AQG is housed in an 8-pin ultra-miniature package.
These features make this device ideally suited to storing program codes in
applications such as portable information devices, which are required to
have increasingly more compact dimensions. Moreover, by using the small
sector erase function this product is also suitable for the parameter or the
date storage usage with comparatively little rewriting times that becomes a
capacity shortage in EEPROM.
