The 93LC46BXT-I/SN is an 8-pin serial EEPROM memory chip manufactured by Microchip Technology. It has 1024 bits of EEPROM memory and operates at 3.0 to 5.5 volts. It has a byte-wide write/erase feature, and the write cycles are self-timed and no separate programming voltage is required. Data is read and written with an a two-wire serial interface. This memory chip is ideal for storing data and instructions in non-volatile memory applications, such as printers, modems, PCs, and digital cameras.
