8.2.2 Supported Memories on DDR Interface

  • 16-bit or 32-bit external interface
  • 512 Mbytes of address space on DDR CS and DDR/AES CS in 32-bit mode
  • 256 Mbytes of address space on DDR CS and DDR/AES CS in 16-bit mode
  • Supports 16-bit or 32-bit 8-bank DDR2, DDR3, LPDDR1, LPDDR2 and LPDDR3 memories
  • Automatic drive level control
  • Multiport
  • Scramblable data path
  • Port 0 of this interface has an embedded automatic AES encryption and decryption mechanism (refer to the section Advanced Encryption Standard Bridge (AESB)). Writing to or reading from the address 0x40000000 may trigger the encryption and decryption mechanism depending on the AESB on External Memories configuration.
  • TrustZone: The multiport feature of this interface implies TrustZone configuration constraints. Refer to the section TrustZone Technology for more details.
