PIN Descriptions
Serial Data (SDA): The SDA pin used for sending and receiving data bits in serial mode. Since the SDA pin is
defined as an open-drain connection, a pull-up resistor is needed.
Serial Clock (SCL): The SCL input is used to synchronize data input and output with the clocked out on the
falling edge of SCL.
Device/Page Addresses (A2, A1, A0): The A2, A1, and A0 pins are used to address multiple devices on a
single bus system and should be hard-wired.
The GP24BC01 and GP24BC02 use the A2, A1 and A0 pins to provide the capability for addressing up to
eight 1K/2K devices on a single bus system (please see the Device Addressing section for further details)
&The GP24BC04 uses the A2 and A1 inputs and a total of for 4K device may be addressed on a single bus
system. The A0 pin in not used, but should be grounded if possible.
&The GP24BC08 only uses the A2 input hardwire addressing. On a single bus system, a total of two 8K
devices may be addressed. The A0 and A1 pins are not used, but should be grounded if possible.
&The GP24BC16 does not uses the device address pins, so only one device can be connected to a single
bus system. Therefore, the A0, A1 and A2 pins are not used, but should be grounded if possible.
Write Protect (WP): The GP24BC01/02/04/08/16 has a Write Protect pin that provides hardware data
protection. When connected to ground, the Write Protect pin allows for normal read/write operations. If the WP
pin is connected to VCC, no data can be overwritten.
