ST24C16 Datasheet PDF – 16 Kbit Serial I2C Bus EEPROM IC

The ST24C16 is a 16 Kbit Serial I2C Bus EEPROM with User-Defined Block Write Protection made by STMicroelectronics, supplied in these packages: DIP, SO 8 Pin. The absolute maximum ratings table on this page lists the 6 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the ST24C16 pinout and maximum ratings, with the full datasheet PDF to preview below or download.

This specification covers a range of 16 Kbit I2C bus EEPROM products, the ST24/25C16 and the ST24/25W16. In the text, products are referred to as ST24/25x16 where "x" is: "C" for Standard version and "W" for hardware Write Control version. The ST24/25x16 are 16 Kbit electrically erasable programmable memories (EEPROM), organized as 8 blocks of 256 x8 bits.

These are manufactured in STMicroelectronics’s Hi-Endurance Advanced CMOS technology which guarantees an endurance of one million erase/write cycles with a data retention of 40 years. The ST25x16 operates with a power supply value as low as 2.5V. Both Plastic Dual-in-Line and Plastic Small Outline packages are available.

The memories are compatible with the I2C standard, two wire serial interface which uses a bi-directional data bus and serial clock. The memories carry a built-in 4 bit, unique device identification code (1010) corresponding to the I2C bus definition. The memories behave as slave devices in the I2C protocol with all memory operations synchronized by the serial clock. Read and write operations are initiated by a START condition generated by the bus master. The START condition is followed by a stream of 4 bits (identification code 1010), 3 block select bits, plus one read/write bit and terminated by an acknowledge bit. When writing data to the
