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.
