Table 3: 78-Ball FBGA – x4, x8 Ball Descriptions
Symbol Type Description
[15:13], 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). See Truth Table - Command in
the DDR3 SDRAM data sheet.
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 control and address 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 disa-
bled 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.
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 REFCA.
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 re-
ceiver is a CMOS input defined as a rail-to-rail signal with DC HIGH ≥ 0.8 × VDD and
DC LOW ≤ 0.2 × VDDQ. RESET# assertion and desertion are asynchronous.

refresh) for proper device operation.

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 240Ω 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].

pendent upon the DDR3 SDRAM configuration and operating mode. Taking CKE

input data is masked when LDM is sampled HIGH along with the input data during a
write access. Although the LDM ball is input-only, the LDM loading is
designed to match that of the DQ and DQS balls. LDM is referenced to VREFDQ.
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[15:0], LDQS,

Notes: 1. Maximum DC value may not be greater than 1.425V. The DC value is the linear average
of VDD/VDDQ(t) over a very long period of time (for example, 1 sec).
2. If the maximum limit is exceeded, input levels shall be governed by DDR3 specifications.
3. Under these supply voltages, the device operates to this DDR3L specification.
4. Once initialized for DDR3L operation, DDR3 operation may only be used if the device is
in reset while VDD and VDDQ are changed for DDR3 operation (see Figure 8 (page 27)).

Note: 1. When two VIH(AC) values (and two corresponding VIL(AC) values) are listed for a specific
speed bin, the user may choose either value for the input AC level. 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.

Notes: 1. When two VIH(AC) values (and two corresponding VIL(AC) values) are listed for a specific
speed bin, the user may choose either value for the input AC level. 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 DDR3-800, two input AC levels are defined: VIH(AC160),min and
VIH(AC135),min (corresponding VIL(AC160),min and VIL(AC135),min). For DDR3-800, 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 must use either VIH(AC160),min
with tDS(AC160) of 90ps or VIH(AC135),min with tDS(AC135) of 140ps.
2. When DQ single-ended slew rate is 1V/ns, the DQS differential slew rate is 2V/ns; when
DQ single-ended slew rate is 2V/ns, the DQS differential slew rate is 4V/ns;

Voltage Initialization / Change
If the SDRAM is powered up and initialized for the 1.35V operating voltage range, volt-
age 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.

VDD Voltage Switching
After the DDR3L DRAM is powered up and initialized, the power supply can be altered
between the DDR3L and DDR3 levels, provided the sequence in Figure 8 is maintained.
