DESCRIPTION
These I2C-compatible electrically erasable programmable memory (EEPROM) devices are organized as 32Kx8 bits, and operate down to 2.5 V (for the M24256-AW).
The M24256-A is available in Plastic Dual-in-Line, Plastic Small Outline and Thin Shrink Small Outline packages. The M24256-A is also available in a chip-scale (SBGA) package.

This device is now designated as “Not for New Design”. Please use the M24256-B in all future designs (as described in application note AN1470).
