MCB1_RAS_n

K15

 

 

 

 

MCB1_CAS_n

K16

Command inputs: RAS#, CAS#, and WE# (along with CS#) define

 

 

MCB1_WE_n

K12

the command being entered. *

 

 

 

MCB1_CS_n

--

 

 

 

 

MCB1_CKE_n

D17

Clock enable: CKE HIGH activates, and CKE LOW deactivates, the

 

 

 

 

internal clock signals, input buffers, and output drivers. Taking CKE

 

 

 

 

LOW enables PRECHARGE power-down and SELF REFRESH

 

 

 

 

 

operations (all banks idle), or ACTIVE power-down (row active in any

 

 

 

 

bank). CKE is synchronous for all functions except SELF REFRESH

 

 

 

 

exit. All input buffers (except CKE) are disabled during power-down

 

 

 

 

and self refresh modes.

 

 

 

MCB1_RZQ

N14

Input termination calibration pin used with the soft calibration module.

 

 

 

 

External 100 Ohm resistor to GND.

 

 

 

MCB1_ZIO

 

No connect signal used with the soft calibration module to calibrate

 

 

 

 

the input termination value.

 

 

 

MCB1_CK

G16

Clock: CK is the system clock input. CK and CK# are differential

 

 

 

 

 

clock inputs. All address and control input signals are sampled on the

 

 

MCB1_CK_n

G18

crossing of the positive edge of CK and the negative edge of CK#.

 

 

Input and output data is referenced to the crossing of CK and CK#

 

 

 

 

 

 

 

 

(both directions of the crossing).

 

 

 

MCB1_DQ0

M16

 

 

 

 

MCB1_DQ1

M18

 

 

 

 

MCB1_DQ2

L17

 

 

 

 

MCB1_DQ3

L18

Data input/output: Lower Byte Data bus.

 

 

 

MCB1_DQ4

H17

 

 

 

 

 

 

 

MCB1_DQ5

H18

 

 

 

 

MCB1_DQ6

J16

 

 

 

 

MCB1_DQ7

J18

 

 

 

 

MCB1_LDQS

K17

Data strobe for Lower Byte Data bus: Output with read data, input

 

 

 

 

with write data. DQS is edge-aligned with read data, center-aligned in

 

 

 

 

write data. It is used to capture data.

 

 

 

MCB1_LDM

L16

Input data mask: DM is an input mask signal for write data. Input data

 

 

 

 

is masked when DM is sampled HIGH along with that input data

 

 

 

MCB1_UDM

L15

during a WRITE access. DM is sampled on both edges of DQS.

 

 

 

 

 

 

 

MCB1_DQ8

N17

Data input/output: Upper Byte Data bus.

 

 

 

MCB1_DQ9

N18

 

 

 

 

MCB1_DQ10

P17

 

 

 

 

MCB1_DQ11

P18
