1 Kbit SPI EEPROM in a 2×3 mm UDFN package
The Microchip AT25010B-MAHL-T is a 1 Kbit serial EEPROM with an SPI interface, organized as 128 x 8 bits.
Supply voltage and bus compatibility
The pad is electrically connected to the die substrate and should be tied to ground or left floating per the datasheet recommendation. The small body (2×3 mm) is a space saver on dense mixed-signal boards, but the 0.5 mm pitch means the solder-paste stencil aperture needs careful sizing to avoid bridging.
The part is ROHS3 compliant.
