Description

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 are 2K 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.
