The AT24C04A uses the A2 and A1 inputs for hardwire addressing, and a total of four
4K devices may be addressed on a single bus system. The A0 pin is a no-connect.
WRITE PROTECT (WP): The AT24C02A/04A have a WP pin that provides hardware
data protection. The WP pin allows normal read/write operations when connected to
ground (GND). When the WP pin is connected to V
enabled and operates as shown.
Table 2. Write Protect
AT24C02A, 2K SERIAL EEPROM: The 2K is internally organized with 32 pages of 8
bytes each. Random word addressing requires an 8-bit data word address.
AT24C04A, 4K SERIAL EEPROM: The 4K is internally organized with 32 pages of 16
bytes each. Random word addressing requires a 9-bit data word address.
