LE25U20AMB
CMOS IC
2M-bit (256K × 8)

Serial Flash Memory
Overview
The LE25U20AMB 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
LE25U20AMB 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.
