IS24C01B IS24C02B
PIN CONFIGURATION
8-Pin DIP, SOIC, TSSOP
PIN DESCRIPTIONS
SCL
This input clock pin is used to synchronize the data transfer
to and from the device.
SDA
The SDA is a Bi-directional pin used to transfer addresses and
data into and out of the device. The SDA pin is an open drain
output and can be wire-Or'ed with other open drain or open
collector outputs. The SDA bus requires a pullup resistor to
Vcc.

A0, A1, A2
The A0, A1 and A2 are the device address inputs. The
IS24C01B/02B uses the A0, A1, and A2 for hardware addressing
and a total of 8 devices may be used on a single bus system.
When the A0, A1, or A2 inputs are left floating, the input
internally defaults to zero.
WP
WP is the Write Protect pin. If the WP pin is tied to V
EEPROM, the entire array becomes Write Protected (Read
only). When WP is tied to GND or left floating normal read/
write operations are allowed to the device.
