Overview
Part information
MX25U25635FZ2I-10G overview
MX25U25635FZ2I-10G is a 256Mbit, 1.8V Serial NOR Flash device supporting single, dual and quad I/O. The Z2I-10G ordering code identifies the 8 × 6 mm 8-WSON package, industrial temperature range and 108 MHz speed grade.
Macronix has published migration guidance from the MX25U25635F family to the newer MX25U25645G family. A family migration document is useful for engineering review, but it does not make a differently packaged orderable code a drop-in substitute.
