PRODUCTION DATA
The EPI SDRAM Mode combines high performance, low cost, and low pin use to access up to 512 megabits (Mb) of external memory. Main features of the EPI SDRAM interface are:
See Figure 7-18 for a snapshot of the SDRAM Mode registers and supported memory sizes. For more detailed maps of the SDRAM Mode, see Table 7-4.
