Pin Description
Device Address Select Pin 0. This pin determines the LSB of the device address
required to communicate using the 2-wire interface. The A0 pin has an on-chip pull-down resistor.
Device Address Select Pin 1. This pin determines the intermediate bit of the device address re-
quired to communicate using the 2-wire interface. The A1 pin has an on-chip pull-down resistor.
Device Address Select Pin 2. This pin determines the MSB of the device address required to com-
municate using the 2-wire interface. The A2 pin has an on-chip pull-down resistor.
Supply Voltage.
Write Protect Control Pin. This pin is a CMOS compatible input. When LOW, Write Protection is
enabled preventing any “Write” operation. When HIGH, various areas of the memory can be pro-
tected using the Block Lock bits BL1 and BL0. The WP pin has an on-chip pull-down resistor, which
enables the Write Protection when this pin is left floating.
Serial Clock. This is a TTL compatible input pin. This input is the 2-wire interface clock controlling
data input and output at the SDA pin.
Serial Data. This pin is the 2-wire interface data into or out of the device. It is TTL
compatible when used as an input, and it is Open Drain when used as an output. This pin requires
an external pull up resistor.
Current Generator Output. This pin sinks or sources current. The magnitude and direction of the
current is fully programmable and adaptive. The resolution is 8 bits.
