Overview

CAT34TS04 は、温度センサ (TS) と 4-Kb のシリアル存在検出 (SPD) EEPROM の組み合わせであり、JEDEC TSE2004av DDR4 仕様を実装しています。TS では 1 秒あたり 10 回以上温度を測定します。ホストは、シリアル・インタフェース経由で温度の測定値を取得し、内部レジスタに格納されているトリガの上限と下限、臨界値と比較します。制限範囲の逸脱は、オープンドレイン EVENT ピンで知らせることができます。4-Kb メモリは、個別にアドレス指定可能な 2 つの 2-Kb バンクに分割されます (TSE2004av 仕様では SPD ページと呼ばれます)。各バンクには 2 つの 1-Kb ブロックが含まれており、可逆ソフトウェア書き込み保護 (RSWP) コマンドで書き込み保護できます。SPD EEPROM は、16 バイト幅の書き込みバッファを特長としており、標準 (100 kHz)、Fast (400 kHz) および Fast Plus (1 MHz) I2C プロトコルをサポートします。
