3. Pin Description
4. Memory Organization
5175E–SEEPR–3/09
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 bidirectional 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 AT24C16B does not use the device address pins, which lim-
its the number of devices on a single bus to one.
WRITE PROTECT (WP): The AT24C16B 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
and operates as shown in
Table 3-1.
AT24C16B, 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.
