2016年采购过OMAPL138EZWTA4版,现在查看2017的datasheet该版本没有了,只有OMAPL138EZWTD4,是停产了吗,可我们采购说还可以买到,所以前来核实下。
Tony Tang:
就没有过A4吧,只有A3,或D4。456MHz的没有宽温范围的。
目前手册是sprs586J,前面一版的手册是sprs586I,是2014看的版本,没有2016的版本,你是在哪看到有A4的?截个图看看。

这是我们去年采购的余料

回复 user4379950:
看来是赶巧了,A4本来是不公开的型号,是针对特定客户要求定制的,在SPRS586H版的datasheet里不小心列上去了。刚好被你们看到还下订了。
也就是说这个型号是有,但是有些限制,就是不能在这个宽温条件下长时间工作,寿命有限。
可以看看下面贴子的讨论:

This part should not have been listed as an orderable part, as this was not a broad market part, it was done for a specific customer with a very limited set of power on hours that matched their use-case etc. I have notified the marketing team a few times to have this removed from the system, such that it does not get appended to the datasheet by the automatic package option addendum system etc. Will make sure this is addressed.
