Ball CONFIGURATION ( HY5V22(L)F(P) Series)
Ball DESCRIPTION
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 ~ A11
Address
Row Address : RA0 ~ RA11, 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
