.The MX25U51245GZ4I00 is a WSON 8/I°/FLASH MEMORY 1.8V, 512M-BIT CMOS MXSMIO® SERIAL MULTI I/O manufactured by Macronix. This device is a low voltage, high performance non-volatile memory that operates at either 1.8V or 3.3V and supports up to 4 I/O, including DTR/RXD, DTC/TXD, DR/SCL, and DC/SDA. The device delivers up to 512 megabits of flash memory and features 86s sector erase requirements, error-correction code (ECC) technology, and authentication capability. This device is ideal for embedded and industrial applications where space is a constraint due to its small package size (8-pin WSON). The device is also JEDEC-compliant and supports the JEDEC Serial Peripheral Interface (SPI).
