• Manufacturer Part Number: r5s72060w200fpv
• Description: 32-bit Risc Microcomputer Superhtm Risc Engine Family / Sh7200 Series
• Manufacturer: Renesas Electronics Corporation.

As shown in figure 8.17, two sets of SDRAMs of 32 Mbytes or smaller can be connected to the
same CS space by using RASU, RASL, CASU, and CASL. In this case, a total of 8 banks are
assigned to the same CS space: 4 banks specified by RASL and CASL, and 4 banks specified by
RASU and CASU. When accessing the address with A25 = 0, RASL and CASL are asserted.
When accessing the address with A25 = 1, RASU and CASU are asserted.
