The Microchip 24LC32A, a 32 Kbit I2C serial EEPROM, is documented in this 586 KB PDF that the index lists as a schematic, though it reads as a datasheet.

Covering the 25AA320, 25LC320 and 25C320, this 383 KB PDF is listed as a schematic but is in practice the datasheet for a Microchip family of 32 Kbit SPI serial EEPROMs.

A 329 KB PDF datasheet for the 24AA52 and 24LCS52 serial EEPROMs, small 2 Kbit I2C memories.
