AX24C02A/04A/08A/16A
2K/4K/8K /16K-bit 2-WIRE SERIAL CMOS EEPROM
GENERAL DESCRIPTIO
The AX24C02A/04A/08A/16A provides
2048/4096/8192/16384 bits of serial electrically
erasable and programmable read-only memory
(EEPROM) organized as 256/512/1024/2048 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
AX24C02A/04A/08A/16A is available in space-saving
SOP-8, TSSOP-8, DFN-8 and SOT23-5 packages and
is accessed via a two-wire serial interface.
