Description
LR24C02/LR24C04/LR24C08/LR24C16 provides 2048/4096/8192/16384 bits of serial electrically
erasable and programmable read-only memory (EEPROM) organized as 256/512/1024/2048 words of 8
bits each. The device is optimized for use in many industrial and commercial applications where
low-power and low-voltage operations are essential. The LR24C02/LR24C04/LR24C08/LR24C16 is
available in space-saving 8-lead PDIP, 8-lead SOP, and 8-lead TSSOP packages and is accessed via a
two-wire serial interface.

Device Addressing
The 2K, 4K, 8K and 16K EEPROM devices all require an 8-bit device address word following a start
condition to enable the chip for a read or write operation (see to Figure 4 on page 7).
The device address word consists of a mandatory "1", "0" sequence for the first four most significant bits
as shown. This is common to all the Serial EEPROM devices.
The next 3 bits are the A2, A1 and A0 device address bits for the 2K EEPROM. These 3 bits must
compare to their corresponding hardwired input pins.
The 4K EEPROM only uses the A2 and A1 device address bits with the third bit being a memory page
address bit. The two device address bits must compare to their corresponding hardwired input pins. The
