Overview

A5191HRTは、ハイウェイアドレス指定可能リモートトランスデューサ（HART）フィールド機器およびマスターで使用するシングルチップのCMOSモデムです。このモデムと少数の外部受動部品により、変調、復調、受信のフィルタリング、キャリアの検出、送信信号の整形を含む、HART物理層要件を満たすために必要なすべての機能を提供します。 A5191HRTはSYM20C15とピン互換です。SYM20C15とのピン互換についての詳細は、「ピン説明」および「機能説明」セクションをご覧ください。A5191HRTは、1200ビット/秒で位相連続周波数偏移変調（FSK）を使用します。電力を低減するために、送信動作中は受信回路をディスエーブルし、受信動作中は送信回路をディスエーブルします。これによりHART通信で使用される半二重動作が可能になります。

  • Highway Addressable Remote Transducer (HART) field instruments and masters

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
