1、256M Double Data Rate Synchronous DRAMA3S56D30FTPA3S56D40FTPPIN FUNCTIONCLK, /CLKInputClock: CLK and /CLK are differential clock inputs. All address and controlinput signals are sampled on the crossing of the positive edge of CLK andnegative edge of /CLK. Output (read) data is referenced to the cros
2、sings ofCLK and /CLK (both directions of crossing).CKEInputClock Enable: CKE controls Power Down and Self Refresh. Taking CKE LOW provides Precharge Power Down or Self Refresh (all banks idle),or Active Power Down (row active in any bank).Taking CKE HIGH provides Power Down exit or Self Refresh exit
3、.After Self Refresh is started, CKE becomes asynchronous input. Power Down and Self Refresh is maintained as long as CKE is LOW./CSInputChip Select: When /CS is HIGH, any command means No Operation./RAS, /CAS, /WEInputCombination of /RAS, /CAS, /WE defines basic commands.A0-12InputA0-12 specify the
4、Row / Column Address in conjunction with BA0,1. The Row Address is specified by A0-12. The Column Address is specified by A0-9(x8) and A0-8(x16). A10 is also used to indicate precharge option. When A10 is HIGH at a Read / Write command, an Auto Prechargeis performed. When A10 is HIGH at a Precharge
5、command, all banks are precharged.

Edge-aligned with read data, centered in write data. Used to capture write data. For the x16, LDQS corresponds to the data on DQ0-DQ7;
7、 UDQS correspond to the data on DQ8-DQ15SYMBOLTYPEDESCRIPTIONDM (x8)InputInput 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 during a write access. DM is sampled on both edges of DQS. Although DM pins are input only, the
8、 DM loading matches the DQand DQS loading. For the x16, LDM corresponds to the data on DQ0-DQ7; UDM corresponds to the data on DQ8-DQ15.Input / OutputVREFInputSSTL_2 reference voltage.UDQS, LDQS (x16)UDM, LDM (x16)AVR 2650 AVR 2650 harman/kardonharman/kardon 121RadioFans.CN 收音机爱 好者资料库 12-Bit, 170 MH
