DESCRIPTION
Pin numbers may not correlate with symbols. Refer to Pin Assignment tables on page 3 for more information
PIN NUMBERS
118, 119, 120
Input Command Inputs: RAS#, CAS#, and WE# (along with S#)
define the command being entered.
35, 37, 158, 160
CK0, CK0#,
Input Clock: CK, CK# are differential clock inputs. All address and
CK1, CK1#,
control input signals are sampled on the crossing of the
positive edge of CK,and negative edge of CK#. Output data
(DQs and DQS) is referenced to the crossings of CK and CK#.
96
CKE0
Input Clock Enable: CKE HIGH activates and CKE LOW deactivates
the internal clock, input buffers and output drivers. Taking
CKE LOW provides PRECHARGE POWER-DOWN and SELF
REFRESH operations (all device banks idle), or ACTIVE POWER-
DOWN (row ACTIVE in any device bank).CKE is synchronous
for POWER-DOWN entry and exit, and for SELF REFRESH
entry. CKE is asynchronous for SELF REFRESH exit and for
disabling the outputs. CKE must be maintained HIGH
throughout read and write accesses. Input buffers (excluding
CK, CK# and CKE) are disabled during POWER-DOWN. Input
buffers (excluding CKE) are disabled during SELF REFRESH.
CKE is an SSTL_2 input but will detect an LVCMOS LOW level
after V
DD
is applied and until CKE is first brought HIGH. After
CKE is brought HIGH, it becomes an SSTL_2 input only.
121
S0#
Input Chip Selects: S# enables (registered LOW) and disables
(registered HIGH) the command decoder. All commands are
masked when S# is registered HIGH. S# is considered part of
the command code.
116, 117
BA0, BA1
Input Bank Address: BA0 and BA1 define to which device bank an
ACTIVE, READ, WRITE, or PRECHARGE command is being
applied.
A0–A11
(128MB)
Input Address Inputs: Provide the row address for ACTIVE
99
(256MB, 512MB),
100,
101, 102, 105, 106, 107, A0–A12
(256MB, 512MB)
commands, and the column address and auto precharge bit
108, 109, 110, 111, 112,
(A10) for READ/WRITE commands, to select one location out
115
of the memory array in the respective device bank. A10
sampled during a PRECHARGE command determines whether
the PRECHARGE applies to one device bank (A10 LOW, device
bank selected by BA0, BA1) or all device banks (A10 HIGH).
The address inputs also provide the op-code during a MODE
REGISTER SET command. BA0 and BA1 define which mode
register (mode register or extended mode register) is loaded
during the LOAD MODE REGISTER command.
11, 25, 47, 61, 133, 147,
DQS0–DQS7
Input/ Data Strobe: Output with READ data, input with WRITE data.
169, 183
Output DQS is edge-aligned with READ data, centered in WRITE data.
Used to capture data.
12, 26, 48, 62, 134, 148,
DM0–DM7
Input Data Write Mask. DM LOW allows WRITE operation. DM HIGH
170, 184
blocks WRITE operation. DM lines do not affect READ
operation.
