4K-Bit Serial EEPROM
2-Wire Bus Interface
General Description
The NM24C04U/05U devices are 4K (4,096) bit serial interface
CMOS EEPROMs (Electrically Erasable Programmable Read-
Only Memory). These devices fully conform to the Standard I2C
2-wire protocol which uses Clock (SCL) and Data I/O (SDA) pins
to synchronously clock data between the "master" (for example a
microprocessor) and the "slave" (the EEPROM device). In addi-
tion, the serial interface allows a minimal pin count packaging
designed to simplify PC board layout requirements and offers the
designer a variety of low voltage and low power options.
NM24C05U incorporates a hardware "Write Protect" feature, by
which, the upper half of the memory can be disabled against
programming by connecting the WP pin to V
CC. This section of
memory then effectively becomes a ROM (Read-Only Memory)
and can no longer be programmed as long as WP pin is connected
to V
CC.
Fairchild EEPROMs are designed and tested for applications requir-
ing high endurance, high reliability and low power consumption for a
continuously reliable non-volatile solution for all markets.
