General description:
The ST24C08 is a 8Kbit electrically erasable programmable memory (EEPROM), organized as 4 blocks of 256 * 8 bits.
The memory operates with a power supply value as low as 2.5V. Both Plastic Dual-in-Line and Plastic Small Outline packages
are available.
Features:
n Minimum 1 million ERASE/WRITE cycles with over 10 years data retention
n Single supply voltage:4.5 to 5.5V
n Two wire serial interface, fully IýC-bus compatible
n Byte and Multibyte write (up to 8 bytes)
n Page write (up to 16 bytes)
n Byte, random and sequential read modes
n Self timed programming cycle
