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

Note:
Bus Width
32 bits
(Bus Width = 32 Bits, 16-Byte Transfer (Number of Burst 4), Wait Cycles Inserted in First
Access = 2, Wait Cycles Inserted in Second and Subsequent Access Cycles = 1)

D31 to D0
A25 to A0
DACKn*
When the bus width is 16 bits, the access size is 16 bits, and the BST[1:0] bits in
CSnWCR are 10, the number of bursts and access count depend on the access start
address. At address H'xxx0 or H'xxx8, 4-4 burst access is performed. At address H'xxx4
or H'xxxC, 2-4-2 burst access is performed.
