• Die Sales: Wafer Form, Waffle Pack, and Bumped Wafers 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 2wire 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, 8ball 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.
