General Description
The AM24LC02 is a non-volatile, 2048-bit serial
EEPROM with enhanced security device and
conforms to all specifications in I2C 2-wire protocol.
The whole memory can be disabled (Write Protected)
by connecting the WP pin to Vcc. This section of
memory then becomes unalterable unless WP is
switched to Vss. The AM24LC02's communication
protocol uses CLOCK(SCL) and DATA I/O(SDA)
lines to synchronously clock data between the
master (for example a microcomputer)and the slave
EEPROM device(s) .In addition, the bus structure
allows for a maximum of 16K of EEPROM memory.
This is supported by the family in 2K, 4K, 8K, 16K
devices, allowing the user to configure the memory
as the application requires with any combination of
EEPROMs (not to exceed 16K).
Anachip EEPROMs are designed and tested for
application requiring high endurance, high reliability,
and low power consumption.
