NM24Wxx  
2K/4K/8K/16K-Bit Standard 2-Wire Bus Interface  
Serial EEPROM with Full Array Write Protect  
General Description  
Features  
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.  
Hardware Write Protect for entire memory  
Low Power CMOS  
200µA active current typical  
10µA standby current typical  
1µA standby typical (L)  
0.1µA standby typical (LZ)  
The entire ememory can be disabled (Write Protected) by con-  
nectingtheWPpintoVCC.Thememorythenbecomesunalterable  
IIC Compatible interface  
unless WP is switched to VSS  
.
— Provides bidirectional data transfer protocol  
Sixteen byte page write mode  
— Minimizes total write time per byte  
This communications protocol uses CLOCK (SCL) and DATA  
I/O (SDA) lines to synchronously clock data between the master  
(forexampleamicroprocessor)andtheslaveEEPROMdevice(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.  
Self timed write cycle  
— Typical write cycle time of 6ms  
Endurance: 1,000,000 data changes  
Data retention greater than 40 years  
Packages available: 8-pin DIP, 8-pin SO, and 8-pin TSSOP  
Available in three temperature ranges  
- Commercial: 0° to +70°C  
Fairchild EEPROMs are designed and tested for applications  
requiringhighendurance, highreliabilityandlowpowerconsump-  
tion.  
- Extended (E): -40° to +85C  
- Automotive (V): -40° to +125°C
