    • VDD2 = 1.06-1.17V
    • VDDQ = 1.06-1.17V (LPDDR4)
    • VDDQ = 0.57-0.65V (LPDDR4X)
  • LVSTL(Low Voltage Swing Terminated Logic) I/O Interface
  • Internal VREF and VREF Training
  • Dynamic ODT :
    • DQ ODT :VSSQ Termination
    • CA ODT :VSS Termination
  • 16n Pre fetch DDR architecture
  • Single data rate (multiple cycles) command/address bus
  • Bidirectional/differential data strobe per byte of data (DQS/DQS#)
  • Programmable burst lengths (16 or 32)
  • Operation Temperature -40°C to 105°C
  • Committed long term support with very low obsolescence or mask change rate.
