CIRCUIT DESCRIPTION
3. Pin Description of ICOs
3-1 64 Bit SDRAM : HY57V641620HGT (DVD Part IC63)
Pin No.Pin NameI/ODescription
The system clock input. all other inputs are registered to the SDRAM on
38CLKI
the rising edge of CLK.
Controls internal clock signal and when deactivated, the SDRAM will be one
37CKE-
of the states among power down, suspend or self refresh.
19CS-Enables or disables all inputs except CLK, CKE, and DQM.
Selects bank to be activated during RAS activity.
20,21BA0,BA1-
Selects bank to be read/written during CAS activity.
22~26Row address : RA0~RA11, Column address : CA0~CA7
A0~A11-
29~35Auto-precharge flag : A10
16,17,18WE,CAS,RAS-WE, CAS and RAS define the operation.
15,39LDQM,UDQMI/O Controls output buffers in read mode and masks input data in write mode.
