Part information
MX30LF4G28AD-XKI overview
MX30LF4G28AD-XKI is a 4Gbit SLC NAND Flash device organized as x8 and designed for 2.7V to 3.6V operation. The exact -XKI code specifies the industrial-temperature 63-VFBGA package with a 0.8 mm ball pitch.
This generation requires host-side 8-bit ECC and uses a 4,096-byte data area plus a 256-byte spare area per page. These details can affect controller support, bad-block management and firmware, so they should be checked at the exact part-number level rather than inferred from another MX30LF4G device.
