CAT24AA16
EEPROM Serial 16-Kb I2C
Description
The CAT24AA16 is a EEPROM Serial 16−Kb I2C device internally
organized as 2048x8 bits.
The device features a 16−byte page write buffer and supports
100 kHz, 400 kHz and 1 MHz I2C protocols.
Data is written by providing a starting address, then loading 1 to 16
contiguous bytes into a Page Write Buffer, and then writing all data to
non−volatile memory in one internal write cycle. Data is read by
providing a starting address and then shifting out data serially while
automatically incrementing the internal address count.
