关于OMAP-L138的工作温度的问题

Other Parts Discussed in Thread: OMAP-L138

请教各位,我在OMAP-L138的芯片资料上看到这款芯片有三种温度类型的,如下图:

现在我的芯片上写的内容如下,

                   OMAPL138B

                   ZWT

                   I9A6SLW  G|  A375

                   21  527  ZWT

我不知道我的是属于哪个等级的,我个认为是属于第三种EXTENDED的,因为有个下标A375中含有A,但不确定,也有可能属于第一种。不知道各位怎么看?
