DESCRIPTION
PIN CONFIGURATION
The CW24C02/04/08/16 is Electrically Erasable PROM. The
device is organized as one block of 256/512/1024/2048 x 8-bit
memory with 2-wire serial interface. Low-voltage design permits
operation down to 1.8V, with standby and active currents of only
1μA and 1mA respectively. The CW24C02/04/08/16 also has a
page write capability for up to 8/16/16/16 bytes of data.

PIN DESCRIPTION
No. Name
Function Description
Address input. The A2, A1 and A0 pins are device address inputs.
1 A0 The CW24C02 uses the A2, A1 and A0 inputs for hard wire addressing and a
total of eight CW24C02 devices may be addressed on a single bus system
(device addressing is discussed in detail under the Device Addressing
section).
The CW24C04 uses the A2 and A1 inputs for hard wire addressing and a total
2 A1 of four CW24C04 devices may be addressed on a single bus system. The A0
pin is a no connect and can be connected to GND.
The CW24C08 only uses the A2 input for hardwire addressing and a total of
two CW24C08 devices may be addressed on a single bus system. The A0
and A1 pins are no connects and can be connected to GND.
3 A2
The CW24C16 does not use the device address pins, which limits the number
of devices on a single bus to one. The A0, A1 and A2 pins are no connects
and can be connected to GND.
Serial address and data I/O. The SDA pin is bi-directional for serial data
5 SDA transfer. It is an open-drain device, therefore the SDA bus requires a pull-up
resistor to VCC (typical 10kΩ).
Serial clock input. The SCL input is used to synchronize the data transfer to
6 SCL and from each EEPROM device. It’s positive edge clock data into the device
and negative edge clock data out of the device.
Write protect. The WP pin that provides hardware data protection. The WP pin
allows normal read/write operations when connected to ground (GND). When
7 WP the WP pin is connected to VCC, the write protection feature is enabled and
read only.
4 GND Circuit ground pin.
8 VCC Positive supply voltage.
