Description
The FM24C02/04/08/16 provides 2048/4096/8192/16384 bits of
serial electrically erasable and programmable read-only
memory (EEPROM) organized as 256/512/1024/2048
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 (A2, A1, A0):
The A2,
A1 and A0 pins are device address inputs that are
hard wired for the FM24C02. As many as eight 2K
devices may be addressed on a single bus system
(device addressing is discussed in detail under the
Device Addressing section).
The FM24C04 uses the A2 input for hardwire
addressing and a total of two 4K devices may be
addressed on a single bus system. The A0 and A1
pins are no connects.
The FM24C08 only uses the A2 input for hardwire
addressing and a total of two 8K devices may be
addressed on a single bus system. The A0 and A1
pins are no connects.
The FM24C16 does not use the device address
pins, which limits the number of devices on a
single bus to one. The A0, A1 and A2 pins are no
connects.
WRITE PROTECT (WP):
The FM24C02/04/08/16 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.

9-bit data word address for random word
addressing.
FM24C08, 8K SERIAL EEPROM:
Internally organized
with 64 pages of 16 bytes each, the 8K requires a
10-bit data word address for random word
addressing.
FM24C16, 16K SERIAL EEPROM:
Internally organized
with 128 pages of 16 bytes each, the 16K requires
an 11-bit data word address for random word
addressing.
