Preliminary 2Gb: x4, x8, x16 Automotive DDR3L SDRAM Ball Assignments and Descriptions Table 3: 78-Ball FBGA - x4, x8 Ball Descriptions Symbol Type Description A[14:13], A12/BC#, A11, A10/AP, A[9:0] Input Address inputs: Provide the row address for ACTIVATE commands, and the column address and auto precharge bit (A10) for READ/WRITE commands, to select one location out of the memory array in the respective bank. A10 sampled during a PRECHARGE command determines whether the PRECHARGE applies to one bank (A10 LOW, bank selected by BA[2:0]) or all banks (A10 HIGH). The address inputs also provide the op-code during a LOAD MODE command. Address inputs are referenced to VREFCA. A12/BC#: When enabled in the mode register (MR), A12 is sampled during READ and WRITE commands to determine whether burst chop (on-the-fly) will be performed (HIGH = BL8 or no burst chop, LOW = BC4 burst chop). BA[2:0] Input Bank address inputs: BA[2:0] define the bank to which an ACTIVATE, READ, WRITE, or PRECHARGE command is being applied. BA[2:0] define which mode register (MR0, MR1, MR2, or MR3) is loaded during the LOAD MODE command. BA[2:0] are referenced to VREFCA. CK, CK# Input Clock: CK and CK# are differential clock inputs. All address and control input signals are sampled on the crossing of the positive edge of CK and the negative edge of CK#. Output data strobe (DQS, DQS#) is referenced to the crossings of CK and CK#. CKE Input Clock enable: CKE enables (registered HIGH) and disables (registered LOW) internal circuitry and clocks on the DRAM. The specific circuitry that is enabled/disabled is dependent upon the DDR3 SDRAM configuration and operating mode. Taking CKE LOW provides PRECHARGE power-down and SELF REFRESH operations (all banks idle) or active power-down (row active in any bank). CKE is synchronous for power-down entry and exit and for self refresh entry. CKE is asynchronous for self refresh exit. Input buffers (excluding CK, CK#, CKE, RESET#, and ODT) are disabled during power-down. Input buffers (excluding CKE and RESET#) are disabled during SELF REFRESH. CKE is referenced to VREFCA. CS# Input Chip select: CS# enables (registered LOW) and disables (registered HIGH) the command decoder. All commands are masked when CS# is registered HIGH. CS# provides for external rank selection on systems with multiple ranks. CS# is considered part of the command code. CS# is referenced to VREFCA. DM Input Input data mask: DM is an input mask signal for write data. Input data is masked when DM is sampled HIGH along with the input data during a write access. Although the DM ball is input-only, the DM loading is designed to match that of the DQ and DQS balls. DM is referenced to VREFDQ. DM has an optional use as TDQS on the x8 device. ODT Input On-die termination: ODT enables (registered HIGH) and disables (registered LOW) termination resistance internal to the DDR3 SDRAM. When enabled in normal operation, ODT is only applied to each of the following balls: DQ[7:0], DQS, DQS#, and DM for the x8; DQ[3:0], DQS, DQS#, and DM for the x4. The ODT input is ignored if disabled via the LOAD MODE command. ODT is referenced to VREFCA. RAS#, CAS#, WE# Input Command inputs: RAS#, CAS#, and WE# (along with CS#) define the command being entered and are referenced to VREFCA. RESET# Input Reset: RESET# is an active LOW CMOS input referenced to VSS. The RESET# input receiver is a CMOS input defined as a rail-to-rail signal with DC HIGH 0.8 x VDDQ and DC LOW 0.2 x VDDQ. RESET# assertion and deassertion are asynchronous. DQ[3:0] I/O PDF: 09005aef85419fbc 2Gb_auto_ddr3l_sdram.pdf - Rev. A 06/13 EN Data input/output: Bidirectional data bus for the x4 configuration.

DQ[7:0] are referenced to VREFDQ. DQS, DQS# I/O Data strobe: Output with read data. Edge-aligned with read data. Input with write data. Center-aligned to write data. TDQS, TDQS# I/O Termination data strobe: Applies to the x8 configuration only. When TDQS is enabled, DM is disabled, and the TDQS and TDQS# balls provide termination resistance. VDD Supply Power supply: 1.35V, 1.283-1.45V operational; compatible to 1.5V operation. VDDQ Supply DQ power supply: 1.35V, 1.283-1.45V operational; compatible with 1.5V operation. VREFCA Supply Reference voltage for control, command, and address: VREFCA must be maintained at all times (including self refresh) for proper device operation. VREFDQ Supply Reference voltage for data: VREFDQ must be maintained at all times (including self refresh) for proper device operation. VSS Supply Ground. VSSQ Supply DQ ground: Isolated on the device for improved noise immunity. ZQ Reference External reference ball for output drive calibration: This ball is tied to an external 240 resistor (RZQ), which is tied to VSSQ. NC - No connect: These balls should be left unconnected (the ball has no connection to the DRAM or to other balls). NF - No function: When configured as a x4 device, these balls are NF. When configured as a x8 device, these balls are defined as TDQS#, DQ[7:4]. PDF: 09005aef85419fbc 2Gb_auto_ddr3l_sdram.pdf - Rev.

Whichever value is used, the associated setup time for that AC level must also be used. Additionally, one VIH(AC) value may be used for address/command inputs and the other VIH(AC) value may be used for data inputs. For example, for DDR3L-800, two input AC levels are defined: VIH(AC160),min and VIH(AC135),min (corresponding VIL(AC160),min and VIL(AC135),min). For DDRL-800, the address/ command inputs must use either VIH(AC160),min with tIS(AC160) of 215ps or VIH(AC135),min with tIS(AC135) of 365ps; independently, the data inputs may use either VIH(AC160),min or VIH(AC135),min.

For DDRL-800, the data inputs must use either VIH(AC160),min with tIS(AC160) of 90ps or VIH(AC135),min with tIS(AC135) of 140ps; independently, the address/command inputs may use either VIH(AC160),min or VIH(AC135),min.

Rising input signal shall become equal to or greater than VIH(AC) level and Falling input signal shall become equal to or less than VIL(AC) level. Voltage Initialization / Change If the SDRAM is powered up and initialized for the 1.35V operating voltage range, voltage can be increased to the 1.5V operating range provided that: * Just prior to increasing the 1.35V operating voltages, no further commands are issued, other than NOPs or COMMAND INHIBITs, and all banks are in the precharge state. * The 1.5V operating voltages are stable prior to issuing new commands, other than NOPs or COMMAND INHIBITs. * The DLL is reset and relocked after the 1.5V operating voltages are stable and prior to any READ command. * The ZQ calibration is performed. tZQinit must be satisfied after the 1.5V operating voltages are stable and prior to any READ command. If the SDRAM is powered up and initialized for the 1.5V operating voltage range, voltage can be reduced to the 1.35V operation range provided that: * Just prior to reducing the 1.5V operating voltages, no further commands are issued, other than NOPs or COMMAND INHIBITs, and all banks are in the precharge state. * The 1.35V operating voltages are stable prior to issuing new commands, other than NOPs or COMMAND INHIBITs. * The DLL is reset and relocked after the 1.35V operating voltages are stable and prior to any READ command. * The ZQ calibration is performed. tZQinit must be satisfied after the 1.35V operating voltages are stable and prior to any READ command.
