3.7.2 NOR flash
The S32G2 QuadSPI module provides a common interface for a single, dual, and octal NOR flash memory,
and HyperFlash memory.
The S32G274A QuadSPI module on S32G-VNP-GLDBOX connects to a NOR flash chip (MX25UW51245G
64MB). MX25UW51245G has an octal flash interface with simultaneous read and write, double transfer
rate(DTR) mode and operational clock frequency up to 200 MHz. The figure below shows the connection
between the S32G274A and the NOR flash.

3.7.3 SD/eMMC
The S32G274A uSDHC module on the S32G-VNP-GLDBOX can connects to the SD card or the eMMC, and
user can change the connection through SW3. The figure below shows the connections between the
S32G274A and SD/eMMC.
