#154216 - P89V51RD2 Responding to: ???'s previous message |
You can realy replace the P89C51RD2 for the new P89V51RD2, there is only a small diference:
In P89C51RD2 you must short PSEN to ground and reset and program to entry in program mode. In P89V51RD2 you just need to press reset and during a feew seconds one or 2(Check the Datasheet) the chip stays in program mode if you delay the programing the chip goes out the program mode and starts application. Pay attention if you program the P89V51RD2 in the same way as The C version you can damage the bootloader. In Flashmagic just choose the right chip. Regards. |
