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
以上来自于百度翻译 以下为原文 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。
以上来自于百度翻译 以下为原文 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。
以上来自于百度翻译 以下为原文 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…)
以上来自于百度翻译 以下为原文 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...) |

在经销商的供应链中仍然有大量的A1。
以上来自于百度翻译 以下为原文 There appears to be Plenty of A1 still in the Distributor Supply Chain. |

你好,我有165个A1零件,它们还能交换吗?对于下一个订单,完整的卷轴,有没有办法从标签识别模具修订级别,或者我只是把检查信息只接受单位的日期代码今天或更大?约瑟夫扬克斯
以上来自于百度翻译 以下为原文 hello, I have a 165 of the A1 parts, can they be exchanged also? For the next order, full reel, is there a way to from the label to identify die revison level or do i just put in the inspection information to only accept units with a date code of today or greater? thanks bill Yonkers |

正如上面提到的,现在所有的东西都已经转变成A3了。不是在DigiKig——我刚买了5个,它们都是A1设备。

我拼命寻找APIC32 MZ2048 EFM100-I/PT修订A3样本,因为我与A1由于I2C勘误有问题。我有2个样本,但似乎都是A1批1:PIC32 MZ2048 EFM100代码:1551 AR8PART 2:PIC32 MZ2048 EFM100代码:1648 GHVOW如何得到它?有没有办法知道在Microchip直接上哪些版本是可用的?我现在看到这个股票:PIC32 MZ2048 EFM100-I/PT QT。一千七百四十
以上来自于百度翻译 以下为原文 I'm desperately looking for a PIC32MZ2048EFM100-I/PT revision A3 samples since I'm having issues with A1 due to I2C Errata. I've 2 lot of samples but seems to be both A1. BATCH 1: PIC32MZ2048EFM100 Code: 1551AR8 BATCH 2: PIC32MZ2048EFM100 Code: 1648GHV How to get it? Is there a way to know what revision is actually available on Microchip Direct? I see this stock now: PIC32MZ2048EFM100-I/PT Qt. 1740 |
