EEPROM 24C02 SMD
EEPROM (electrically erasable programmable read-only memory) is user-modifiable read-only memory (ROM) that can be erased and reprogrammed (written to) repeatedly through the application.
24C02 I2C EEPROM
The 24C02 EEPROM has 2 K bit electrically erasable programmable memories (EEPROM), organized as 256 x 8 bits. The memories operate with a power supply value as low as 1.8V for the 24C02R only. 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. This is used together with 3 chip enable inputs(E2, E1, E0) so that up to 8 x 2K devices may be attached to the I2C bus and selected individually. The memories behave as a slave device 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 7 bits (identification code 1010), plus one read/write bit and terminated by an acknowledge bit.
