The STMicroelectronics M24C16-RDS6TG is a 16Kbit serial EEPROM organized as 2K x 8 bits, accessed over an I²C bus at up to 400 kHz. It stores calibration constants, configuration parameters, or small lookup tables in a non-volatile memory that retains data through power cycles. Typical applications include industrial sensor modules, telecom line cards, and consumer appliances that require field-reprogrammable parameter storage without battery backup.
The 900 ns access time is the time from the I²C address byte to the first data bit appearing on SDA. The write cycle time is 5 ms per page or word.
