The ST24/25E64 are 64K bit electrically erasable programmable memories (EEPROM), organized as 8 blocks of 1024x8 bits. The ST25E64 operates with a power supply value as low as 2.5V. Both Plastic Dual-in-Line and Plastic Small Outline packages are available.
The ST24E64 and ST25E64 are 64K bit electrically erasable programmable memories (EEPROM) organized as 8 blocks of 1024 8 bits. They are compatible with the I2C extended addressing standard and utilize a two-wire serial interface supporting a 400kHz protocol. The ST24E64 operates with a supply voltage of 4.5V to 5.5V, while the ST25E64 supports a lower voltage range of 2.5V to 5.5V.
