Description
Address inputs: Specifies the row or column address. Also used to load the mode registers. The
maximum LPDDR address is determined by density and configuration. Consult the LPDDR
product data sheet for the maximum address for a given density and configuration. Unused
address pins become RFU.
Bank address inputs: Specifies one of the 4 banks.
Column select: Specifies the command to execute.
CK is the system clock. CK and CK# are differential clock inputs. All address and control signals
are sampled and referenced on the crossing of the rising edge of CK with the falling edge of
CK#.
Clock enable:
CKE0 is used for a single LPDDR product.
CKE1 is used for dual LPDDR products.
Chip select:
CS0# is used for a single LPDDR product.
CS1# is used for dual LPDDR products and is considered RFU for single LPDDR MCPs.
Data mask: Determines which bytes are written during WRITE operations.
For x16 LPDDR, unused DM balls become RFU.
