Hi to all,
i want to interface EEPROM to Psoc 3 Externally,can any body help in this regard.
Which EEPROM device are you planning to interface with PSoC?
In general, EEPROMs support I2C interface. In that case PSoC should act as an I2C Master and the EEPROM device as a slave.
Some EEPROM devices also have the provision of setting their addresses (last 2 bits or so) externally, so that multiple EEPROM devices can be made available on the same bus thereby increasing the memory available.
i am trying to use an external eeprom i can get no error when i'm trying to write but when i try to read there is nothing
can you help me with that ?
i have attached my file
To add to my previous comment, there are also SPI based EEPROMs available.
The SPI based EEPROMs can be accessed at a faster rate (typically 3MHz SPI Clock). These EEPROMs may support 8-bit or 16-bit data formats.
PSoC should act as an SPI in this case, with apporpriate mode selected.

I have the old version of the project. I think that this project was created in Creator 1.0 Beta 5.
I don't know when will this Chrome attachment issue would get resolved.
I updated the project to the latest Creator version, PSoC Creator 2.2
This project demonstrates the EEPROM interface with an example of an I2C based EEPROM 24C04.
The project is attached with this post.
The version of creator i am using is Creator 2.0. may be the project was not compatable so i got the following error.
Error: sdb.M0062: An error occurred trying to retrieve the DRCs for an instance, 'I2C'. Unable to locate and customize component 'I2C_v3_30' used in schematic 'C:\Documents and Settings\Adm\My Documents\PSoC Creator\Example_I2C_EEPROM\Example_I2C_EEPROM.cydsn\TopDesign\TopDesign.cysch'.
Actually i am using Del Sig ADC with 8 bit resolution, 8500 SPS, and it will run for 5 seconds so i get too many samples but the RAM avalaible in PSoC 3 is 8 kb only, so i am going for EEPROM interface to accomodate so many samples , is this a correct option any other way?
You can update to the latest version, that is, PSoC Creator 2.2
The link to download this version is here.
