Basic Timing
The SH7040 Series supports 2 CAS format DRAM access. The DRAM access basic timing is a
minimum of 3 cycles for normal mode. Figure 10.7 shows the basic DRAM access timing. DRAM
space access is controlled by
RAS, CASx, and RDWR signals. The following signals are
associated with transfer of these actual byte locations:
CASHH (bits 31–24), CASHL (bits 23–16),
CASH (bits 15–8), and CASL (bits 7–0). However, the signals for ordinary space, WRx and RD,
are also output during the DMAC single transfer column address cycle period. Tp is the precharge
cycle, Tr is the RAS assert cycle, Tc is the CAS assert cycle and Tc2 is the read data fetch cycle.
