PDF datasheet for the 93C46CB, a variant of the 93C46 1 Kbit Microwire serial EEPROM, the smallest and most common member of the 93-series family. The CB suffix denotes a specific version, whose exact meaning should be read from the document. These chips store configuration bytes, MAC addresses and calibration data. Use the pinout, organisation details and timing tables when setting a programmer for 8-bit or 16-bit mode, and read the chip and save its contents before writing new data.
