s Electrical Characteristics (continued)
4. AC Characteristics (continued)
13) Memory Access Timing (setup procedure)
This LSI allows the timing with which DRAM is accessed to be adjusted by setting the memory control expansion
registers SR0F and SR11. Set up the optimal cycle timing for the specifications of the DRAM actually used.
1. When fast page mode DRAM is used
2. When EDO DRAM is used
Note) 1. T is one period of MCLK (the divided-by-2 PLL clock: 35 MHz to 65 MHz).
2. Ta: The delay time from RAS# low to CAS# low. This period can be set to a value in the range 2T to 5T.
Tb: The CAS# low-level period. This period can be set to a value in the range T to 2T.
Tc: The RAS# high-level period. This period can be set to a value in the range 2T to 5T.
3. Ta is set with memory control register 3 (SR11) bits 0 and 1.
Tb is set with memory control register 2 (SR0F) bit 1.
Tc is set with memory control register 3 (SR11) bits 4 and 5.
4. For fast page mode DRAM, the random access cycle will be Ta
+ Tb + Tc. (min.)
5. For EDO DRAM, the random access cycle will be Ta
+ Tb + Tc + T. (min.)
