EC24C128A/256A 128K/256K-bit 2-WIRE SERIAL CMOS EEPROM
General Description
Features
The EC24C128A/EC24C256A provides 131,072 /262,144 bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as16,384/32,768 words of 8 bits each. The device is optimized for use in many industrial and mercial applications where low-power and low-voltage operation are essential. The EC24C128A/EC24C256A is available in space-saving PDIP-8,SOP-8, MSOP-8 and TSSOP-8 packages and is accessed via a twowire serial interface.
