Product Overview
The MX25L4006EZUI-12G is a 4Mbit serial NOR Flash memory from Macronix with Dual Output mode support. It features standard SPI interface operating at up to 86MHz clock frequency in single I/O mode and 80MHz in Dual Output mode. The device comes in an 8-USON (2x3mm) ultra-small package, operates from 2.7V to 3.6V, and supports industrial temperature range. With 4KB uniform sectors and hardware/software protection features, it provides compact non-volatile storage for space-constrained embedded applications.
