Product Overview
The MX25L6406EM2I-12G is a 64Mbit serial NOR Flash memory from Macronix featuring standard SPI interface with Dual Output mode capability. Operating at up to 86MHz clock frequency, it is organized as 8M x 8 bits and comes in an 8-SOP (200mil) package. The device operates from 2.7V to 3.6V supply voltage and supports industrial temperature range of -40°C to +85°C. It features 4KB sectors and 64KB blocks for flexible erase operations, along with hardware write protection and secured OTP memory. While not recommended for new designs, it remains a reliable choice for legacy applications and replacement needs.
