Signal Name
Description
Direction / Buffer
Type
SB_MA[15:0]
Memory Address: These signals are used to provide the
multiplexed row and column address to the SDRAM.
O
SB_CKP[1:0]
SB_CKN[1:0]
SDRAM Differential Clock: Channel B SDRAM Differential
clock signal pair. The crossing of the positive edge of SB_CKP
and the negative edge of its complement SB_CKN are used to
sample the command and control signals on the SDRAM.
O
SB_CS#[1:0]
Chip Select: (1 per rank). These signals are used to select
particular SDRAM components during the active state. There
is one Chip Select for each SDRAM rank.
O
SB_CKE[3:0]
Clock Enable: (1 per rank). These signals are used to:
• Initialize the SDRAMs during power-up
• Power down SDRAM ranks
• Place all SDRAM ranks into and out of self-refresh during
STR
• When 1R DDR3L (SODIMM/MD) CKE[0] is used
• When 2R DDR3L (SODIMM/MD) CKE[1:0] are used
O
SB_ODT
On Die Termination: Active Termination Control.

LPDDR3 Memory Channel A Interface (Memory-Down) Signals
Signal Name
Description
Direction / Buffer
Type
SA_DQ[63:0]
Data Bus: Channel A data signal interface to the SDRAM data
bus.
I/O
SA_DQSP[7:0]
SA_DQSN[7:0]
Data Strobes: SA_DQS[7:0] and its complement signal
group make up a differential strobe pair. The data is captured
at the crossing point of SA_DQS[7:0] and its SA_DQS#[7:0]
during read and write transactions.
I/O
SA_CAA[9:0]
Command Address: These signals are used to provide the
multiplexed command and address to the SDRAM.
O
SA_CAB[9:0]
Command Address: These signals are used to provide the
multiplexed command and address to the SDRAM.
O
SA_CKP[1:0]
SA_CKN[1:0]
SDRAM Differential Clock: Channel A SDRAM Differential
clock signal pair. The crossing of the positive edge of SA_CKP
and the negative edge of its complement SA_CKN are used to
sample the command and control signals on the SDRAM.
O
SA_CS#[1:0]
Chip Select: (1 per rank). These signals are used to select
particular SDRAM components during the active state. There
is one Chip Select for each SDRAM rank.
O
SA_CKE[3:0]
Clock Enable: (1 per rank). These signals are used to:
• Initialize the SDRAMs during power-up
• Power down SDRAM ranks
• Place all SDRAM ranks into and out of self-refresh during
STR
• When 1R LPDDR3 CKE[0] and CKE[2] are used for Rank 0
• When 2R LPDDR3 CKE[0] and CKE[2] are used for Rank 0
& CKE[1] and CKE[3] are used for Rank 1
O
SA_ODT
On Die Termination: Active Termination Control.
