16 Kbit Serial I2C Bus EEPROM with User-Defined Block Write Protection
1 MILLION ERASE/WRITE CYCLES, with 40 YEARS DATA RETENTION SINGLE SUPPLY VOLTAGE: – 4.5V to 5.5V for ST24x16 versions – 2.5V to 5.5V for ST25x16 versions HARDWARE WRITE CONTROL VERSIONS: ST24W16 and ST25W16 TWO WIRE SERIAL INTERFACE, FULLY I2C BUS COMPATIBLE BYTE and MULTIBYTE WRITE (up to 8 BYTES) for the ST24C16 PAGE WRITE (up to 16 BYTES) BYTE, RANDOM and SEQUENTIAL READ MODES SELF TIMED PROGRAMING CYCLE AUTOMATIC ADDRESS INCREMENTING ENHANCED ESD/LATCH UP PERFORMANCES DESCRIPTION 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 endurTable 1. Signal Names
