Why would you like to do that? If your answer is you need more space than Internal EEPROM, that's ok. If not, Internal PIC EEPROMs have a capacity of 256-512 Bytes, that's pretty much. What do you want to store there?GatorGuy said:I am looking into EEPROM memory from Microchip and would like to get some input on how they work. Does anyone have any schematics on how to connect them to a PIC? Also do they hold there memory when their power is cut or do they empty it?
Oh I see, that's alright.GatorGuy said:Pretty much to just add more memory. At this point it is only research. I am learning what I can now for future projects. For now internal memory is enough for what I need to do. But I might see a need for it later.
Yep I do...Agent 009 said:I encountered this problem with my recent project, if u remember Jay... I needed much more memory, so I had either to get EEPROM or shorten the program... I chose the latter one, though my teacher stated that it isn't hard to work with EEPROMs: connect'em from PIC ports to pins, looking at teh datasheet (obviously) of the EEPROM...
Yes, it is 2wire, Half-Duplex synchronus serial communication in speeds from 100Khz thru 400Khz to 1Mhz max.Agent 009 said:I2C... Is that serial communication?
Or you can use PIC with I2C peripheral, and that very easy and fast.williB said:agent009 he said Kilo HZ not MHZ
a 4 mhz PIC should be able to handle 100 KHZ easily..
Yeah, but if he said from 100Khz thru 400Khz to 1Mhz max... 4 MHz in not included???williB said:agent009 he said Kilo HZ not MHZ

That's not PIC frequency, it's the BUS speed.Agent 009 said:Yeah, but if he said from 100Khz thru 400Khz to 1Mhz max... 4 MHz in not included???williB said:agent009 he said Kilo HZ not MHZ

That's VERY different! PICs frequency is simple how fast PIC works, you know that. But I2C clock is different, It is synchronising every bit on the I2C bus, and therefore it defines the transfer speed...Agent 009 said:So what's the difference :? :!: :!:
Yes, if you run I2C at its max (1Mhz), it will transfer aprox. 128KB/s...Someone Electro said:Can it then transfer 1Mbit/s if its run at 1Mhz?
:shock:
thats about 100 KB/s and thats fast enugh for digital audio transfer.
Is it realy that fast?
