Topic: Programming a DIP8 EEPROM with a duemilanove (Read 1 time) previous topic - next topic


I am new to eeprom programming, especially using a microcontroller. I dont want to spend large amounts of money on a programmer. The chip is a Winbond 25Q64BVAIG on a DIP8 socket, it was originally a BIOS for an Asus motherboard. I cannot find a datasheet on this specific chip, but http://www.winbond-usa.com/NR/rdonlyres/591A37FF-007C-4E99-956C-F7EE4A6D9A8F/0/W25Q64BV.pdf seems to be the same chip on a surface mount form factor. It has a max power rating of 3.6v, so I would have to program using the 3.3v power on the board, as opposed to 5v. I have the pinout and no idea where to go from here. How would I go about programming this chip with a new BIOS? I have a solderless breadboard and a lot of low-power caps and resistors, leds and such.


How would I go about programming this chip with a new BIOS?

First question that comes to mind is this. Do you have the new BIOS you want to put on the chip? In what form?
