IP Product: Renewal part number for LPDDR2 SDRAM Controller Supporting UniPHY

Does the ALTDQ_DQS2 IP support LPDDR2 memory?


The ALTDQ_DQS2 IP does not support LPDDR2 memory.

LPDDR2 memory requires the DQS Tracking feature to align the DQS and DQS Enable signals.

The ALTDQ_DQS2 IP does not support the DQS Tracking feature, therefore the ALTDQ_DQS2 IP does not support LPDDR2.
