8 Read Operations

Read operations are initiated the same way as write operations with the exception that the Read/Write Select bit in the device address byte must be a logic ‘1’. There are four read operations:

  • Current Address Read
  • Random Address Read
  • Sequential Read
  • Serial Number Read
Note: The AT24CS16 contains a single Address Pointer register, which is shared by both the EEPROM and the serial number. As such, when changing from one region to the other, the first read operation in the new region should begin with a dummy write sequence (i.e., a random read operation with the new region’s device address and word address bytes) in order to ensure the Address Pointer is set to a known value. See Serial Number Read for additional requirements on the serial number read.
