Description
The FM24C16A provides wide operation voltage of 16384
bits of serial electrically erasable and programmable
read-only memory (EEPROM) organized as 2048 words of
8 bits each. The device is optimized for use in many
industrial and commercial applications where low-power
and low-voltage operations are essential.

Pin Description
SERIAL CLOCK (SCL):
The SCL input is used to
positive edge clock data into each EEPROM device
and negative edge clock data out of each device.
SERIAL DATA (SDA):
The SDA pin is bi-directional
for serial data transfer. This pin is open-drain driven
and may be wire-ORed with any number of other
open-drain or open-collector devices.
DEVICE/PAGE ADDRESSES:
The FM24C16A does
not use the device address pins, which limits the
number of devices on a single bus to one.
WRITE PROTECT (WP):
The FM24C16 A has a Write
Protect pin that provides hardware data protection.
The Write Protect pin allows normal read/write
operations when connected to ground (GND).
When the Write Protect pin is connected to V
CC,
the
write protection feature is enabled.
