#156190 - two chips Responding to: ???'s previous message |
hey
I am currently working with a eeprom m24c32 (manufac:ST). It is a serial rom. It works on the I2C protocol. Writing the code for it would be cakewalk if you know the protocol. Even if you dont you can read the manual provided by phillips and the data sheet of m24c32 (i personally found the latter to be more useful and easy to understand). The other alternative is to use EPROM 27512. It is quite old and it has to be UV erased. The advantage of using this is that you dont need to learn something new (i dont think that this is an adv. as it is always useful to learn something new) but the programming is simpler. The disadvantage would be that you will have to do a lot of wiring for multiplexing the address and the data lines. cheers |
