Input
NAND READY/BUSY: NAND-specific signal; low-true output.
NAND READ ENABLE: NAND-specific signal; drives the data onto the flash bus after the falling
edge of N-RE#.
This signal increments the internal column address and reads out each data.
LPSDRAM CLOCK ENABLE: LPSDRAM-specific signal; high-true input.
LPSDRAM BANK SELECT: LPSDRAM-specific input signals.
D-BA[1:0] selects one of four banks in the LPSDRAM die.
LPSDRAM ROW ADDRESS STROBE: LPSDRAM-specific signal; low-true input.
D-RAS#, together with A[MAX:0], D-BA[1:0], D-CKE, D-CS#, D-CAS#, and D-WE#, define
the LPSDRAM command or operation. D-RAS# is sampled on the rising edge of D-CLK.
LPSDRAM COLUMN ADDRESS STROBE: LPSDRAM-specific signal; low-true input.
D-CAS#, together with A[MAX:0], D-BA[1:0], D-CKE, D-CS#, D-RAS#, and D-WE#, define
the LPSDRAM command or operation. D-CAS# is sampled on the rising edge of D-CLK.
LPSDRAM CHIP ENABLE: LPSDRAM-specific signal; low-true input.
When low, D-CS# selects the associated LPSDRAM memory die and starts the command input
cycle.
When D-CS# is high, commands are ignored but operations continue.
LPSDRAM DATA MASK: LPSDRAM-specific signal; high-true input.
When high, D-DM[1:0] controls masking of input data during writes and output data during
reads.
LPSDRAM UPPER/LOWER DATA STROBE: DDR LPSDRAM-specific input/output signals.
D-DQS1 and D-DQS0 provide as output the read data strobes, and as input the write data
strobes.
SRAM CHIP SELECTS: SRAM-specific signals.
SRAM UPPER/LOWER BYTE ENABLES: SRAM-specific signals; low-true inputs.
FLASH PROGRAM/ERASE VOLTAGE: Flash specific.
F-VPP supplies program or erase power to the flash die.
• When low, N-RY/BY# indicates the NAND device is busy performing a read, program, or
• When high, N-RY/BY# indicates the NAND device is ready.
• When high, D-CKE indicates that the next D-CLK edge is valid.
• When low, D-CKE indicates that the next D-CLK edge is invalid and the selected LPSDRAM
• D-CS#, together with A[MAX:0], D-BA[1:0], D-CKE, D-RAS#, D-CAS#, and D-WE#,
• D[2:1]-CS# are dedicated to LPSDRAM die #2 and die #1, respectively, if present.
• D-DM1 corresponds to the data on DQ[15:8].
• D-DM0 corresponds to the data on DQ[7:0].
• D-DQS1 corresponds to the data on DQ[15:8].
• D-DQS0 corresponds to the data on DQ[7:0].
• S-CS1# low-true input.
• S-CS2# high-true input.
• When both are asserted, S-CS1# and S-CS2 select the SRAM die.
• When either is deasserted, the SRAM die is deselected and its power is reduced to
• When low, S-UB# enables DQ[15:8] and S-LB# enables DQ[7:0] during SRAM read and
• When high, S-UB# masks DQ[15:8] and S-LB# masks DQ[7:0].
