Overview
The LPDDR Synchronous Dynamic Random Access Memory (SDRAM) Controller is a general-purpose memory controller that interfaces with industry standard LPDDR memory devices/modules compliant with JESD209B, LPDDR SDRAM Standard, and provides a generic command interface to user applications. This IP core reduces the effort required to integrate the LPDDR memory controller with the remainder of the application and minimizes the need to directly deal with the LPDDR memory interface.
Key features
- Interfaces to industry standard LPDDR SDRAM according to JESD209B
- Double-data rate architecture; two data transfers per clock cycle
- Bi-directional data strobe per byte of data (DQS)
- Programmable auto refresh support
- Data mask support – one mask per byte
- Power down and deep power down support
- Supports power-on initialization
- Supports re-initialization after a deep power down
- Dynamic I/O training after initialization
- Periodic I/O retraining after an auto refresh burst
- Dynamic memory clock power off during self refresh, power down and deep power down operations
- Supports single-port operation
- Supports full, half and quarter array self refresh
- Status register read support
- TCSR programmability through MRS
