ONFI / Toggle NAND PHY
Maturity plannedTargets ASIC (CMOS) onlyDifficulty HardPriority 2
NAND flash PHY for ONFI NV-DDR2/NV-DDR3 and Toggle DDR with DQS-based capture, DLL, ODT and ZQ calibration.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ctrl | in/out | APB control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| dq | inout | parallel | 8 | |
| dqs | inout | differential pair | 1 | |
| re | out | differential pair | 1 | |
| dfi_wr | in | parallel | 32 | |
| dfi_rd | out | parallel | 32 |
