Memory

QSPI flash memory and DDR4 SDRAM are mounted on the RTK9743U11C01000BE as external memories.

Please refer to the following for details.

2.3.1

QSPI Flash Memory

Figure 2.1 shows a block diagram of the Serial Flash Memory Interface.

The QSPI flash memory is controlled by the SPI Multi I/O Bus Controller (SPIBSC) that is with built-in to the

RZ/G2UL. This memory supports both single data rate (SDR) and double data rate (DDR) transfers at 66 MHz and 50

MHz clock frequency.

NOTE

The pull-up resistor on the clock line

“RZ_QSPI0_SPCLK” is optional.
