在ZLG广州新赛格 店 购得P89V51RC2FN (FA64-0761 -zG0633 B2)
使用Flash Magic下载程序,出现: -------------------------------------------------------------------- | The device signature does not match the expected values. Accessing | | a device using the wrong protocol could render the device unusable.| | Do you want to continue? | ---------------------------------------------------------------------
用 Read Signature菜单命令返回: Manufactruer ID: 0xBF Device ID1: 0x91
而后,查阅NXP文档显示: P89C51RD2 = 15h C2h 82h P89V51RD2 = BFh 91h P89C51RC2 = 15h C2h 8Ah P89LV51RD2 = BFh 90h P89C51RB2 = 15h C2h 8Ch P89V51RC2 = BFh 9Bh P89C51RA2 = 15h C2h 8Fh P89LV51RC2 = BFh 9Ah P89V51RB2 = BFh 9Eh P89LV51RB2 = BFh 9Fh 不清楚 原因何在?
注:1)下载操作、下载支持的硬件以及PC软件,对以前所购的P89V51RD2FN(CP0156.00 kzN0449 AC)一切正常。 2)芯片上的标识是Philipps,而不是新名字NXP。
