Overview

LE25S161 は、16M ビット (2048K 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。電源を 1 個使用します。LE25S161 は、シリアル・フラッシュメモリ・デバイスに固有の特徴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、ますます小型化を要求されている携帯用情報端末など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、これらの特徴すべてによるものです。また、LE25S161 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。
