Hello,Community

I have two questions.
1.Figure 27 in i.MX 7 Dual Family of Applications Processors Datasheet, Rev. 6
LP5 and LP6 are missing in Table 50. LPDDR3 timing parameters.
Please tell me the parameter value.

2.There is a description of the DRAM_CAS_B signal, but there is no such signal in the LPDDR3 signal.
Is it an address signal?

best regards

Goto

Hi goto11@wantsinc.jp,

It would be better if you refer JEDEC standard for LPDDR3 timings parameters. 

Also, we believe there is a typo in case of DRAM_CAS_B, there is no CAS signal in case of LPDDR3. There should be

DRAM_CAx (command and address bus).
