Description
The AT24C164 provides 16,384 bits of serial electrically erasable and programmable
read only memory (EEPROM) organized as 2048 words of 8 bits each. The device’s
cascadable feature allows up to eight 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 operation are essential. The AT24C164 is available in space
saving 8-lead PDIP and 8-lead JEDEC SOIC packages and is accessed via a two-
wire serial interface. In addition, this device is available in 2.7V (2.7V to 5.5V) and
1.8V (1.8V to 5.5V) versions.
