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 specifications in the Standard IIC 2-wire protocol and are designed to
minimize device pin count, and simplify PC board layout requirements.
■ Extended operating voltage 2.7V – 5.5V
■ 400 KHz clock frequency (F) at 2.7V - 5.5V
■ 200µA active current typical
10µA standby current typical
1µA standby current typical (L)
0.1µA standby current typical (LZ)
The upper half (upper 8Kbit) of the memory of the NM24C17 can be
write protected by connecting the WP pin to VCC. This section of
memory then becomes unalterable unless WP is switched to VSS.
■ IIC compatible interface
– Provides bi-directional data transfer protocol
■ Schmitt trigger inputs
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 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 information.)
■ Sixteen byte page write mode
– Minimizes total write time per byte
■ Self timed write cycle
Typical write cycle time of 6ms
■ Hardware Write Protect for upper half (NM24C17 only)
■ 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
- Extended (E): -40° to +85C
- Automotive (V): -40° to +125°C
Fairchild EEPROMs are designed and tested for applications requiring high endurance, high reliability and low power consumption.

NOTE: Pins designated as "NC" are typically unbonded pins. However some of them are bonded for special testing purposes. Hence if a signal is applied to these pins, care
should be taken that the voltage applied on these pins does not exceed the VCC applied to the device. This will ensure proper operation.
