LE25S40MB _{4M-bit (512K×8) Serial Flash Memory}
Overview
The LE25S40MB is a SPI bus flash memory device with a 4M bit (512K × 8-bit) configuration. It uses a single 1.8V
power supply. While making the most of the features inherent to a serial flash memory device, the LE25S40MB 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 LE25S40MB 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.
