Description
The Atmel® AT24C16D provides 16,384 bits of Serial Electrically Erasable and
Programmable Read-Only Memory (EEPROM) organized as 2,048 words of 8 bits
each. This device is optimized for use in many industrial and commercial
applications where low power and low voltage operation are essential. The device
is available in space-saving 8-lead SOIC, 8-lead TSSOP, 8-pad UDFN,
8-lead PDIP(1), 5-lead SOT23, 8-ball VFBGA, and 4-ball WLCSP packages. The
entire family of packages operates from 1.7V to 3.6V.
Note: 1. Contact Atmel Sales for the availability of this package.

Pin Name and Functional Description
No Connect: The NC pins are not bonded to a die pad. These pins can be
connected to GND or left floating.
Ground: The ground reference for the power supply. GND should be
connected to the system ground.
Serial Data: The SDA pin is an open-drain bidirectional input/output pin
used to serially transfer data to and from the device.
The SDA pin must be pulled-high using an external pull-up resistor (not to
exceed 10Kin value) and may be wire-ORed with any number of other
open-drain or open-collector pins from other devices on the same bus.
Serial Clock: The SCL pin is used to provide a clock to the device and to
control the flow of data to and from the device. Command and input data
present on the SDA pin is always latched in on the rising edge of SCL, while
output data on the SDA pin is clocked out on the falling edge of SCL.
The SCL pin must either be forced high when the serial bus is idle or
pulled-high using an external pull-up resistor.
Write Protect: Connecting the WP pin to GND will ensure normal Write
operations. When the WP pin is connected to VCC, all write operations to the
memory are inhibited.
Refer to Note 1 for the behavior of the pin when not connected.
Device Power Supply: The VCC pin is used to supply the source voltage to
the device. Operations at invalid VCC voltages may produce spurious results
and should not be attempted.

Note:
1. If the WP pin is not driven, it is internally pulled down to GND. In order to operate in a wide variety of
application environments, the pull-down mechanism is intentionally designed to be somewhat strong. Once
these pins are biased above the CMOS input buffer’s trip point (~0.5 x VCC), the pull-down mechanism
disengages. Atmel recommends connecting these pins to a known state whenever possible.
