5.3.5 Memory
5.3.5.1 Memory Organization
The SAMA5D3 series processor features a DDR/SDR memory interface and an External Bus Interface
(EBI) to permit interfacing to a wide range of external memories and to almost any kind of parallel
peripheral.
5.3.5.2 Resources allocation.
This section describes the memory devices that equip the SAMA5D3 series-CM board.
„ Two SDRAM/DDR2 used as main system memory. MT47H128M16 - 2 Gb - 16 Meg x 16 x 8 banks,
the board provides up to 2 Gb on-board, soldered DDR2 SDRAM. The memory bus is 32 bits wide
and operates with up to 166 MHz.
