NM24C04/05 – 4K-Bit Standard 2-Wire Bus
Interface Serial EEPROM
February 2000
General Description
The NM24C04/05 devices are 4096 bits of CMOS non-volatile
electrically erasable memory. These devices conform to all speci-
fications in the Standard IIC 2-wire protocol and are designed to
minimize device pin count, and simplify PC board layout require-
ments.
The upper half (upper 2Kbit) of the memory of the NM24C05 can be
write protected by connecting the WP pin to VCC. This section of
memory then becomes unalterable unless WP is switched to VSS.
This communications protocol uses CLOCK (SCL) and DATA
I/O (SDA) lines to synchronously clock data between the master
(for example a microprocessor) and the slave EEPROM device(s).
The Standard IIC protocol allows for a maximum of 16K of
EEPROM memory which is supported by the Fairchild family in
2K, 4K, 8K, and 16K devices, allowing the user to configure the
memory as the application requires with any combination of
EEPROMs. In order to implement higher EEPROM memory
densities on the IIC bus, the Extended IIC protocol must be used.
(Refer to the NM24C32 or NM24C65 datasheets for more infor-
mation.)
Fairchild EEPROMs are designed and tested for applications requir-
ing high endurance, high reliability and low power consumption.
