If I have got this posting wrong I appologise in advance. My first posting to the list. You should have no problems using a 24C64 instead of a 24C32 providing you have followed the rules regarding the top 4 bits which should be held at 0 you will then be addressing only the bottom 32k of the memory space (for the full address space of the 24C64 you hold the top 3 bits at 0) Fig 5-2 in the 24LC64 datasheet (page 6) refers. If you fancy wasting even more memory u could substitute a 24LC128 or go into MxxxxxxxT memory wastage mode and substitute a 24LC256. The other alternative (which requires a program change) is to use a couple of 24LC16, one with chip select A0 set to 0 and the other set to 1 then toggle that chip select bit instead of Address bit A11. ----- Original Message ----- From: "Rob R" To: Sent: Friday, July 21, 2000 7:04 PM Subject: Re: [EE]: 24C32/24LC32 serial eeprom (Was [EE] 24C32/24LC32 serial eeprom) > Would anyone know if the 24c64 (64k version of the 24c32) would still use the same i2c commands? My software reads bytes from a 24lc32 but since it uses 16bit address it should be able to read addresses up to 65535. You think it would work the same if i switched the 24c32 with a 24c64? > > Rob > > On Fri, 21 Jul 2000 13:17:50 -0400 David Kott wrote: > >> Sorry if ur getting this twice ignore it... > >> > >> Anyone know where to find the 24lc32 or 24c32 that are actually in stock? > >Digikey as well as 8 other places are backordered for months.
