2.8 I2C EEPROM

The TIOL221EVM contains an 8Kb EEPROM device with an I2C interface that can be used for local storage of device parameters accessible when the EVM is used with a microcontroller. This device is not directly connected to the TIOL221 device and is provided solely for the convenience of the user and is not required to evaluate any features of the TIOL221.

Note:

The CAT24C08TDI-GT3 EEPROM device has Device Address of 0x50 and a Write Protect pin (WP) that must be pulled low to allow write access to the protected memory.

For example, the following parameters store the byte values of 0x12 in the EEPROM memory address 0x00 when following standard I2C protocol.

  • Device Address = 0x50
  • Read/Write bit = 0
  • Memory Address = 0x00
  • Data Byte = 0x12
  • WP = Low

Likewise, the following parameters return the values stored in the EEPROM memory address 0x00 when following standard I2C protocol for a selective read.

  • Device Address = 0x50
  • Read/Write bit = 1
  • Memory Address = 0x00
