24AA1025 EEPROM |

Does anyone know if the 1Mbit 24AA1025 EEPROM chip is compatible with the 24256.C driver? I ask because I have the 24AA1025 chip, but no driver (if someone has a 241025.C driver please contact me).
As well, the data sheet for the 24AA1025 says that pin A2 should always bet tied high (5V in my case). The smaller chips 24LC64/128/256 I have always connected pin A2 to ground. Honestly I never knew why I did it, I was told to do that long ago, and have never had to return to the issue.
Thanks,

CCS has a driver for it. It's called 241025.c and it's in this directory:
c:\Program Files\Picc\Drivers
If you don't have it, send an email to CCS support and ask if they
will send it to you. If you ever bought the compiler, I think they will
send it. Give them your user Reference Number. |

Im using a compiler at university...
dont know the reference number... ive picked up a 256kb chip, and am using that for the time being... |

i cant help but ask why the 24AA1025 and 24LC1025 would have different drivers?
I ended up making my own driver... Still using the 256kb chip for now... i have A2 on the EEPROM soldered low. the 24xx1025 data sheet says the device will not operate unless A2 IS high. Blah... im think i should get a little bit high. |

The driver in the Code Library is for 4 of the 128KB 24AA1025 chips
used together, to create a combined eeprom memory array of 512 KB.
You don't need it.
Use the other driver in the link that I provided.
Or use your own driver. |
