TDA4VEN-Q1: CK and CA of LPDDR4 IF

Furuna Yamamoto

Part Number: TDA4VEN-Q1

Tool/software:

Hi.

In LPDDR4 IF, it is usually recognized that a pair of CLK and CA[5:0] are assigned to each 16-bit Data Bus (1ch).

But, the TDA4VEN-Q1 signal has only one set of CLK and CA[5:0].
Is it possible to support 32-bit 1-RANK or 2-RANK products?

Regards,

Yes, the TI TDA4VEN EVM uses a 32-bit (dual channel) , dual rank LPDDR4 memory.

You can see the design files of the EVM at the link below.
