Description

The AT24C32C/64C 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 2-wire bus. The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. The AT24C32C/64C is available in space saving 8-lead PDIP, 8-lead JEDEC SOIC, 8-lead Ultra Lead Frame Land Grid Array (ULA), 8-lead TSSOP, 8-lead Ultra Thin Mini-MAP (MLP2x3) and, 8-ball dBGA2 packages and is accessed via a 2-wire serial interface. In addition, the entire family is available in 1.8V (1.8 to 5.5V) version.
