FM24C16U/17U – 16K-Bit Standard 2-Wire Bus
Interface Serial EEPROM
General Description
The FM24C16U/17U 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. They are
designed to minimize device pin count and simplify PC board
layout requirements.
The upper half (upper 8Kbit) of the memory of the FM24C17U can
be write protected by connecting the WP pin to VCC. This section of
memory then becomes unalterable unless WP is switched to VSS.
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 FM24C32 or FM24C65 datasheets for more informa-
tion.)
Fairchild EEPROMs are designed and tested for applications requir-
ing 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.
