在ZLG广州新赛格 店<br />购得P89V51RC2FN (FA64-0761 -zG0633 B2)<br /><br />使用Flash Magic下载程序,出现:<br /> --------------------------------------------------------------------<br />| The device signature does not match the expected values. Accessing |<br />| a device using the wrong protocol could render the device unusable.|<br />| Do you want to continue? |<br />---------------------------------------------------------------------<br /><br />用 Read Signature菜单命令返回:<br /> Manufactruer ID: 0xBF<br /> Device ID1: 0x91<br /><br />而后,查阅NXP文档显示:<br />P89C51RD2 = 15h C2h 82h P89V51RD2 = BFh 91h<br />P89C51RC2 = 15h C2h 8Ah P89LV51RD2 = BFh 90h<br />P89C51RB2 = 15h C2h 8Ch P89V51RC2 = BFh 9Bh<br />P89C51RA2 = 15h C2h 8Fh P89LV51RC2 = BFh 9Ah<br /> P89V51RB2 = BFh 9Eh<br /> P89LV51RB2 = BFh 9Fh<br />不清楚 原因何在?<br /><br />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。<br /> 2)芯片上的标识是Philipps,而不是新名字NXP。<br /> |
