EC24C32A/64A
32K/64K-bit 2-WIRE SERIAL CMOS EEPROM
General Description
The EC24C32A/EC24C64A 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 applicat-
ions where low-power and low-voltage operation are
essential.
The EC24C32A/EC24C64A is available in space sa-
ving PDIP-8,SOP-8,TSSOP-8,MSOP-8 and DFN-8
(only EC24C32A) packages and is accessed via a
two-wire serial interface.
