General Description
The AM24LC08 is a non-volatile, 8192-bit serial
EEPROM with 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 AM24LC08
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
devices(s) .In addition, the bus structure allows for a
maximum of 16K of EEPROM memory. This
supports the family in 2K, 4K, 8K 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.
