NM24C04U/NM24C05U  
4K-Bit Serial EEPROM  
2-Wire Bus Interface  
General Description  
Functions  
The NM24C04U/05U devices are 4K (4,096) bit serial interface  
CMOS EEPROMs (Electrically Erasable Programmable Read-  
OnlyMemory).ThesedevicesfullyconformtotheStandardI2C™  
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.  
I I2C™ compatible interface  
I 4,096 bits organized as 512 x 8  
I Extended 2.7V – 5.5V operating voltage  
I 100 KHz or 400 KHz operation  
I Self timed programming cycle (6ms typical)  
I "Programming complete" indicated by ACK polling  
I NM24C05U: Memory "Upper Block" Write Protect pin  
Features  
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 VCC. This section of  
memory then effectively becomes a ROM (Read-Only Memory)  
andcannolongerbeprogrammedaslongasWPpinisconnected  
I The I2C™ interface allows the smallest I/O pincount of any  
EEPROM interface  
I 16 byte page write mode to minimize total write time per byte  
to VCC  
.
I Typical 200µA active current (ICCA)  
I Typical 1µA standby current (ISB) for "L" devices and 0.1µA  
standby current for "LZ" devices  
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.  
I Endurance: Up to 1,000,000 data changes  
I Data retention greater than 40 years
