HY57V643220D(L/S)T(P) Series
4Banks x 512K x 32bits Synchronous DRAM
Pin FUNCTION DESCRIPTIONS
Pin
Pin Name
DESCRIPTION
CLK
Clock
The system clock input. All other inputs are registered to the
SDRAM on the rising edge of CLK.
CKE
Clock Enable
Controls internal clock signal and when deactivated, the SDRAM will
be one of the states among power down, suspend or self refresh
CS
Chip Select
Enables or disables all inputs except CLK, CKE and DQM
BA0, BA1
Bank Address
Selects bank to be activated during RAS activity
Selects bank to be read/written during CAS activity
A0 ~ A10
Address
Row Address : RA0 ~ RA10, Column Address : CA0 ~ CA7
Auto-precharge flag : A10
RAS, CAS, WE
Row Address Strobe,
Column Address Strobe,
Write Enable
RAS, CAS and WE define the operation
Refer function truth table for details
DQM0~3
Data Input/Output Mask
Controls output buffers in read mode and masks input data in write
mode
DQ0 ~ DQ31
Data Input/Output
Multiplexed data input / output pin
VDD/VSS
Power Supply/Ground
Power supply for internal circuits and input buffers
VDDQ/VSSQ
Data Output Power/
Ground
Power supply for output buffers
