NM24Wxx 2K/4K/8K/16K-Bit Standard 2-Wire Bus Interface
Serial EEPROM with Full Array Write Protect
PRELIMINARY
March 1999
NM24Wxx
2K/4K/8K/16K-Bit Standard 2-Wire Bus Interface
Serial EEPROM with Full Array Write Protect
General Description
The NM24Wxx devices are 2048/4096/8192/16,384 bits, respec-
tively, of CMOS non-volatile electrically erasable memory. These
devices conform to all specifications in the IIC 2-wire protocol and
are designed to minimize device pin count, and simplify PC board
layout requirements.
The entire ememory can be disabled (Write Protected) by con-
necting the WP pin to V
CC
. The memory then becomes unalterable
unless WP is switched to V
SS
.
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 Fairchild's family in 2K,
4K, 8K, and 16K devices, allowing the user to configure the
memory as the application requires with any combination of
EEPROMs.
Fairchild EEPROMs are designed and tested for applications
requiring high endurance, high reliability and low power consump-
tion.
