EDD2508AETA, EDD2516AETA

Data Sheet E0859E50 (Ver. 5.0)

CKE (input pin)

This pin determines whether or not the next CK is valid. If CKE is high, the next CK rising edge is valid. If CKE is

low. CKE controls power down and self-refresh. The power down and the self-refresh commands are entered when

the CKE is driven low and exited when it resumes to high. CKE must be maintained high throughout read or write

access.

The CKE level must be kept for 1 CK cycle at least, that is, if CKE changes at the cross point of the CK rising edge

and the /CK falling edge with proper setup time tIS, by the next CK rising edge CKE level must be kept with proper

hold time tIH.

DM, UDM, LDM (input pin)

DMs are the reference signals of the data input mask function. DMs are sampled at the cross point of DQS and

VREF. DMs provide the byte mask function. In

16 products, LDM controls the lower byte (DQ0 to DQ7) and UDM

controls the upper byte (DQ8 to DQ15) of write data. When DM = high, the data input at the same timing are

masked while the internal burst counter will be count up.

DQ0 to DQ15 (input/output pins)

Data is input to and output from these pins (DQ0 to DQ7; EDD2508AETA, DQ0 to DQ15; EDD2516AETA).

DQS, UDQS, LDQS (input and output pin)

DQS provide the read data strobes (as output) and the write data strobes (as input). In

16 products, LDQS is the

lower byte (DQ0 to DQ7) data strobe signal, UDQS is the upper byte (DQ8 to DQ15) data strobe signal.

VDD, VSS, VDDQ, VSSQ (Power supply)

VDD and VSS are power supply pins for internal circuits. VDDQ and VSSQ are power supply pins for the output

buffers.
