EEPROM Memory are present in most of the development boards but if you are using a standalone microcontroller you might need to connect an external EEPROM Memory if your code requires more space to store and run optimally or you need to collect more amount of data in it. This EEPROM Memory Module is based on AT24C256 IC which is I2C compatible chip. It has 256kb of memory in 32K*8 configuration. It can be easily interfaced with your microcontroller as it will use only 2 wires to communicate and other two wires to power the device. It can work in high temperature environment so you can use it in industrial applications, automotive applications, robotics and other portable applications. It does not lose data easily and has a long data retention time of more than many years. So it is very suitable for light weight low cost applications.
AT24C256 Module Specifications
- 256kb data memory
- Pull-up resistors required for onboard I2C communication
- All pins are drawn and marked
- I2C Compliant
- More than 1 million erase/write cycles
To use this module you need to power this device you need to power it with 3.3V supply and connect the SDA and SCL pins to corresponding pins of your controller for I2C communication.
