A3S28D40JTP Key Features

  • VDD=VDDQ=2.5V+0.2V (-50)
  • Double data rate architecture ; two data transfers per clock cycle
  • Bidirectional , data strobe (DQS) is transmitted/received with data
  • Differential clock input (CLK and /CLK)
  • DLL aligns DQ and DQS transitions with CLK transitions edges of DQS
  • mands entered on each positive CLK edge
  • Data and data mask referenced to both edges of DQS
  • 4 bank operation controlled by BA0 , BA1 (Bank Address)
  • CAS latency
  • 2.0 / 2.5 / 3.0 (programmable)
