NM24C16/17 – 16K-Bit Standard 2-Wire Bus  
Interface Serial EEPROM  
General Description  
Features  
The NM24C16/17 devices are 16,384 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.  
I Extended operating voltage 2.7V – 5.5V  
I 400 KHz clock frequency (F) at 2.7V - 5.5V  
I 200µA active current typical  
10µA standby current typical  
1µA standby current typical (L)  
0.1µA standby current typical (LZ)  
Theupperhalf(upper8Kbit)ofthememoryoftheNM24C17canbe  
write protected by connecting the WP pin to VCC. This section of  
I IIC compatible interface  
memory then becomes unalterable unless WP is switched to VSS  
.
– Provides bi-directional data transfer protocol  
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 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.)  
I Schmitt trigger inputs  
I Sixteen byte page write mode  
– Minimizes total write time per byte  
I Self timed write cycle  
Typical write cycle time of 6ms  
I Hardware Write Protect for upper half (NM24C17 only)  
I Endurance: 1,000,000 data changes  
I Data retention greater than 40 years  
I Packages available: 8-pin DIP, 8-pin SO, and 8-pin TSSOP  
I Available in three temperature ranges  
- Commercial: 0° to +70°C  
Fairchild EEPROMs are designed and tested for applications requir-  
ing high endurance, high reliability and low power consumption.  
- Extended (E): -40° to +85C  
- Automotive (V): -40° to +125°C
