Atmel datasheet covering the AT24C32 and AT24C64 serial EEPROMs, 32 Kbit and 64 Kbit two-wire I2C memories. The PDF should include pin assignments, device address pins, write-protect behaviour, page-write timing and package options. Technicians rely on such data when reading or rewriting configuration EEPROMs on TVs, monitors, printers and car modules with a programmer, so knowing the capacity and addressing matters. Always save a backup of the original contents before writing, and confirm the capacity marked on the chip matches the image size.
