The Macronix MX66U2G45GXRI00 is a 2Gb serial NOR flash memory organized as 256M x 8 with an SPI interface. It provides 256MB of non-volatile storage in a 24-ball TFBGA package. The MX66U2G45GXRI00 is a high-density SPI NOR flash from Macronix.
This NOR flash is used for code storage (execute-in-place), firmware, and boot images in embedded systems that need reliable serial non-volatile memory. Its 2Gb density suits networking gear, industrial controllers, and SoC-based designs that store large firmware or configuration data. The SPI interface and compact TFBGA package make it easy to integrate on space-limited boards.
