Description

The AT24C164 provides 16,384 bits of serial electrically erasable and programmableread only memory (EEPROM) organized as 2048 words of 8 bits each. The device’scascadable feature allows up to eight devices to share a common two-wire bus. Thedevice is optimized for use in many industrial and commercial applications where lowpower and low voltage operation are essential. The AT24C164 is available in spacesaving 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) and1.8V (1.8V to 5.5V) versions.Table 1. Pin Configurations
