Description

The ACE24C32/64 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’s cascadable feature allows up to

8 devices to share a common two-wire bus. The device is optimized for use in many industrial and

commercial applications where low-power and low-voltage operations are essential.
