AS4C4M32SA-6TIN AS4C4M32SA-6TCN AS4C4M32SA-7TCN Pin Descriptions Table 2. Pin Details Symbol Type Description CLK Input Clock: CLK is driven by the system clock. All SDRAM input signals are sampled on the positive edge of CLK. CLK also increments the internal burst counter and controls the output registers. CKE Input Clock Enable: CKE activates (HIGH) and deactivates (LOW) the CLK signal.

AS4C4M32SA-6TIN AS4C4M32SA-6TCN AS4C4M32SA-7TCN Operation Mode Fully synchronous operations are performed to latch the commands at the positive edges of CLK. Table 3 shows the truth table for the operation commands. Table 3.
AS4C4M32SA-6TIN AS4C4M32SA-6TCN AS4C4M32SA-7TCN Commands 1 BankActivate (RAS# = "L", CAS# = "H", WE# = "H", BA 0,1= Bank, A0-A11 = Row Address) The BankActivate command activates the idle bank designated by the BA0,1 (Bank Activate) signal. By latching the row address on A0 to A11 at the time of this command, the selected row access is initiated. The read or write operation in the same bank can occur after a time delay of tRCD(min.) from the time of bank activation.

This command is similar to the No Operation command.
AS4C4M32SA-6TIN AS4C4M32SA-6TCN AS4C4M32SA-7TCN 16 Clock Suspend Mode Exit / PowerDown Mode Exit command When the internal CLK has been suspended, the operation of the internal CLK is reinitiated from the subsequent cycle by providing this command (asserting CKE "HIGH", the command should be NOP or deselect). When the device is in the PowerDown mode, the device exits this mode and all disabled buffers are turned on to the active state. tXSR(min.) is required when the device exits from the PowerDown mode.
