1.5.2 Pin Connections and short description
Pin No. Pin Name I/O Pin Function
62, 63 CK, CK I The differential system clock Input.
All of the inputs are sampled on the rising edge of the clock except DQ's and DM's that are sam-
pled on both edges of the DQS.
22 CKE I Activates the CK signal when high and deactivates the CK signal when low. By deactivating the
clock, CKE low indicates the Power down mode or Self refresh mode.
12 CS I CS enables the command decoder when low and disabled the command decoder when high.
When the command decoder is disabled, new commands are ignored but previous operations con-
tinue.
11 RAS I Latches row addresses on the positive going edge of the CK with RAS low. Enables row access &
precharge.
10 CAS I Latches column addresses on the positive going edge of the CK with CAS low. Enables column
access.
53 WE I Enables write operation and row precharge.
Latches data in starting from CAS, WE active.
1, 28, 7, 34 DQS0-3 I/O Data input and output are synchronized with both edge of DQS.
44, 67, 50, 35 DM0-3 I Data In mask. Data In is masked by DM Latency=0 when DM is high in burst write. DM0 for DQ0 ~
DQ7, DM1 for DQ8 ~ DQ15, DM2 for DQ16 ~ DQ23, DM3 for DQ24 ~ DQ31.
