Product Overview
The MX25U12872FZNI02 is a 128Mbit (16MB) Serial NOR Flash from Macronix operating at 1.65V to 1.95V with Octal SPI (8-bit) interface and 200 MHz clock rate. The U prefix denotes 1.8V operation. The Octal SPI interface provides 8x data bandwidth (200MB/s read) compared to standard SPI, making it ideal for XIP (Execute-in-Place) applications. The ZNI suffix indicates WSON-8 (6x5mm) package with industrial temperature range.
