2.7.7 Memory and Storage

For volatile memory, the EVM features 8GB of Micron LPDDR4 memory (MT53E2G32D4DE-046). The 32b interface can support transfer rates up to 4000MT/s providing supper fast access to data. While the EVM design is not considered to be reference, the LPDDR4 design portion (both schematic and PCB design) can be considered reference and must be followed when customers are implementing designs.

For fast booting options, the EVM features two different technologies of Serial Flash storage. 512Mb of Octal-xSPI flash is available from Cypress (S28HS512TGABHM010), supporting data rates up to 166MB/s (SDR) and 400MB/s (DDR). 1Gb of Octal-NAND flash is available from Winbond (W35N01JWTBAG), supporting data rates up to 166MB/s (SDR) and 240MB/s (DDR). These storage devices share the same processor interface and cannot be used simultaneously. For details on how to select each device, see Section 2.4.2 and Section 2.7.4.

For mass storage options, the EVM again supports two different memory options. A removable Section 2.5.5 supports external memory cards up to UHS-I data rates (104MB/s). For on-board storage, 32GB is available from Micron (MTFC32GAZAQHD-IT) supporting data rates up to 200MB/s (HS200) and 400MB/s (HS400).
