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 (A2, A1, A0): The A2, A1, and A0 pins are device address inputs
that are hardwired (directly to GND or to Vcc) for compatibility with other AT24Cxx devices.
When the pins are hardwired, as many as eight 512K devices may be addressed on a single bus
system. (Device addressing is discussed in detail under “Device Addressing,” page 8.) A device
is selected when a corresponding hardware and software match is true. If these pins are left
floating, the A2, A1, and A0 pins will be internally pulled down to GND. However, due to capaci-
tive coupling that may appear during customer applications, Atmel ? recommends always
connecting the address pins to a known state. When using a pull-up resistor, Atmel recommends
using 10k ? or less.
WRITE PROTECT (WP): The write protect input, when connected to GND, allows normal write
operations. When WP is connected directly to Vcc, all write operations to the memory are inhib-
ited. If the pin is left floating, the WP pin will be internally pulled down to GND. However, due to
capacitive coupling that may appear during customer applications, Atmel recommends always
connecting the WP pins to a known state. When using a pull-up resistor, Atmel recommends
using 10k ? or less.
