AX24C32A/64A
32K/64K-bit 2-WIRE SERIAL CMOS EEPROM
General Description
The AX24C32A/AX24C64A provides 32,768/65,536
bits of serial electrically erasable and programmable
read-only memory (EEPROM) organized as
4096/8192 words of 8 bits each. The device is
optimized for use in many industrial and commercial
applications where low-power and low-voltage
operation are essential. The AX24C32A/AX24C64A
is available in space-saving SOP-8, TSSOP-8 and
DFN-8 (only AX24C32A) packages and is accessed
via a two-wire serial interface.

AX24C32A/64A
Pin Descriptions
DEVICE/PAGE ADDRESSES (A2, A1 and A0): The A2, A1 and A0 pins are device address inputs that are
hard wired for the AX24C32A/AX24C64A. Eight 32K/64K devices may be addressed on a single bus system
(device addressing is discussed in detail under the Device Addressing section).
SERIAL DATA (SDA): The SDA pin is bi-directional 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.
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.
WRITE PROTECT (WP): The AX24C32A/AX24C64A has a Write Protect pin that provides hardware data
protection. The Write Protect pin allows normal read/write operations when connected to ground (GND). When
the Write Protect pin is connected to VCC, the write protection feature is enabled and operates as shown in the
following Table.
