Atmel AT24C16C
1. 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 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 Atmel^® AT24C16C does not use the device address pins, which limits the
number of devices on a single bus to one.
WRITE PROTECT (WP): The AT24C16C 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 and operates as shown in <blue>Table 1-1.
