PIC32MZ2048EFH 250Mhz怎么说?

我们正试图获得250MHz版本的PIC32 MZ2048 EFH芯片。我们已经有2个供应商交付了所谓的250版本,但是当尝试编程时,它出现为A1版本。芯片上的代码是1636pk7是用250标记的芯片吗?如果没有,我们怎么能知道它们是250MHz而不焊接到一个板上?任何帮助都值得赞赏。约翰

    We are trying to get our hands on the 250Mhz version of the PIC32MZ2048EFH chip. We have had 2 suppliers deliver what was supposedly the 250 version but when trying to program it comes up as A1 revision. The code on the chip is 1636PK7
Are the chips marked with 250?, if not how can we tell if they are 250Mhz without soldering it to a board?

Any help appreciated.

John

批量代码确实使它成为250MHz的部分。不幸的是,它没有外部标记,所以您要么必须从分发服务器中引用订单,要么要求查找批量代码。

    The lot code does make it a 250MHz part. There is, unfortunately, no external marking for it, so you either have to refer to the order from the distributor, or ask for the lot code to be looked up.

谢谢你的回答。为什么我连接程序员时会说A1修订?我期待着A3。

    Thank you for your answer. Why does it say A1 revision when I connect the programmer? I was expecting A3.

批量代码是正确的早期250MHz硅(A1),管理它的方式进入样本库存。如前所述,今天所有的股票都已经转入A3。Bigjon,如果你想给我发一个你的联系细节的PM,我可以得到一些替换的A3部分。(或者,如果你有一个MDC帐户,所有可用的材料现在旋转到A3,这样你就可以订购新的样品…)

    The lot code is correct for early 250Mhz silicon (A1) that managed it's way into sample inventory. As mentioned, everything has transitioned over to A3 in stock today though.
 
 BigJon if you want to send me a PM with your contact details, I can get some replacement A3 parts sampled out. (Or, if you've got an mDirect account, ALL available material is now rotated to A3 so you can order new samples...)
