Product details

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.

Frequently asked questions

What package does the AT25010B-MAHL-T come in?

It comes in an 8-UFDFN with exposed pad (2×3 mm body), also referred to as 8-UDFN (2x3) in the supplier device package field.

Can the AT25010B-MAHL-T be used as a drop-in replacement for the AT25010A?

The AT25010B-MAHL-T is a later revision of the AT25010 family. While the base part number (AT25010) and memory organization (128 x 8) are the same, the 'B' suffix indicates a design revision. Pin compatibility should be verified against the respective datasheets, as the AT25010A may have different timing or supply voltage limits. The evidence does not list the AT25010A specifications, so confirm fit before substituting.
