Overview

LE25S20XA は 2M ビット (256K x 8 ビット) 構成の SPI バス・フラッシュメモリ・デバイスです。1.8 V 電源を 1 個使用します。LE25S20XA は、シリアル・フラッシュメモリ・デバイスに固有の特長をほとんど持ちながら、8 ピンの超小型パッケージに収められています。このデバイスが、さらにコンパクトな寸法のアプリケーションへのプログラムの格納に理想的なのは、これらの特長すべてによるものです。また、LE25S20XA は、小分割セクタ消去機能も持っているため、再書き込みサイクルが少なく、従来の EEPROM では容量不足で対処できないパラメータやデータの格納に適しています。
