Description

The ACE24C32B/ACE24C64B 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 applications where low-power and low-voltage

operation are essential.
