EBD25RB4ALFA
Pin Functions (2)
DQ, CB (input and output pins): Data are input to and output from these pins.
DQS (input and output pin): DQS provide the read data strobes (as output) and the write data strobes (as input).
DM (input pins): DM is the reference signal of the data input mask function. DMs are sampled at the cross point of
DQS and VREF
VDD and VDDQ (power supply pins): 2.5V is applied. (VDD is for the internal circuit and VDDQ is for the output
buffer.)
VDDSPD (power supply pin): 2.5V is applied (For serial EEPROM).
VSS (power supply pin): Ground is connected.
/RESET (input pin): LVCMOS reset input. When /RESET is low, all registers are reset and all outputs are low.
Detailed Operation Part, AC Characteristics and Timing Waveforms
Refer to the EDD1204ALTA, EDD1208ALTA, EDD1216ALTA Series datasheet (E0136E). DM pins of component
device fixed to VSS level on the module board. DIMM /CAS latency = Device CL + 1 for registered type.
