The 24AA64T/SN is a 64K serial EEPROM from Microchip. This non-volatile memory IC features an 8-bit wide two-wire Serial Communication Interface (SCI) and is organized as 8,192 x 8 bits. The device operates with a supply voltage range of 1.8 - 5.5 V and is available in a variety of packages. The internal write protection circuitry allows the device to be written to only once, ensuring data security in the event of an unexpected power loss. The device also features a write protect pin, which, when enabled, locks the device's memory array and prevents further writing. The 24AA64T/SN is ideal for storing small amounts of data, such as system configuration and user settings, due to its small size and low power consumption.
