Commands Mode register set command (/CS, /RAS, /CAS, /WE = Low) The PD45128xxx has a mode register that defines how the device operates. In this command, A0 through A11, BA0(A13) and BA1(A12) are the data input pins. After power ...
Page 10
Write command (/CS, /CAS, /WE = Low, /RAS = High) If the mode register is in the burst write mode, this command sets the burst start address given by the column address to begin the burst write operation. The first ...
Page 11
Self refresh entry command (/CS, /RAS, /CAS, CKE = Low, /WE = High) After the command execution, self refresh operation continues while CKE remains low. When CKE goes high, the PD45128xxx exits the self refresh mode. During self refresh mode, ...
