器件命名规则

为了标示米6体育平台手机版_好二三四开发周期所处的阶段,TI 为器件的部件号分配了前缀。每个商用系列米6体育平台手机版_好二三四成员都具有以下三个前缀之一:x、p 或无前缀。这些前缀代表了从工程原型(带有前缀 x)到完全合格的生产器件(无前缀)的米6体育平台手机版_好二三四开发进化阶段。

器件开发进化流程:

xTRF... – 实验器件,不一定代表最终器件的电气规格

pTRF... – 最终器件,符合最终米6体育平台手机版_好二三四的电气规格,但是未完成质量和可靠性验证

TRF... – 完全合格的生产器件

具有 xp 前缀的器件供货时附带如下免责声明:

“开发的米6体育平台手机版_好二三四用于内部评估用途。”

生产器件已进行完全特性化,并且器件的质量和可靠性已经完全论证。TI 的标准保修证书适用。

预测显示原型器件的故障率大于标准生产器件。由于这些器件的预计最终使用故障率仍未定义,米6体育平台手机版_好二三四 (TI) 建议不要将它们用于任何生产系统。只有合格的米6体育平台手机版_好二三四器件将被使用。

TI 器件的命名规则也包括一个带有器件系列名称的后缀。此后缀表示封装类型和可选的温度范围。Figure 8-1 提供了解读完整器件名称的图例。
