1 SAMA5D2 DDR Controller Capabilities
The SAMA5D2 series MPU features a Multiport DDR-SDRAM Controller (MPDDRC).
The MPDDRC is a high-bandwidth scrambleable 16-bit or 32-bit Double Data Rate (DDR) multiport memory controller supporting up to 512-Mbyte 8-bank DDR2, DDR3, DDR3L, LPDDR1, LPDDR2 and LPDDR3 devices. Data transfers are performed through a 16/32-bit data bus on one chip select.
The controller operates with the following power supplies:
- DDR2, LPDDR1: 1.8V
- DDR3: 1.5V
- DDR3L: 1.35V
- LPDDR2, LPDDR3: 1.2V
This application note covers the implementation of the above-mentioned devices providing layout examples and software support.
