EC24C02A/04A/08A/16A
2K/4K/8K/16K-bit 2-WIRE SERIAL CMOS EEPROM
Description
The EC24C02A/04A/08A/16A provides 2048/4096
/8192/16384 bits of serial electrically erasable and
programmable read-only memory (EEPROM) org-
anized 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 EC24C02A/04A/08A/16A is available in space
saving PDIP-8,SOP-8, TSSOP-8,MSOP8, DFN-8
and SOT23-5 packages and is accessed via a two-
wire serial interface.
