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 commercial 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 two-
wire serial interface.
