Tms320C6202 External Memory Interface - Texas Instruments TMS320C6201 Reference Manual

Figure 9–4. TMS320C6202 External Memory Interface
The EMIF signals of the 'C6202 are shown in Figure 9–4. The 'C6202 has
combined the SDRAM and SBSRAM signals, such that only one of these two
memory types can be used in a system. These memories run off CLKOUT2,
which is equal to 1/2x the CPU clock rate.
