IS46LQ32128A - 4Gb Mobile LPDDR4/LPDDR4X

Download the IS46LQ32128A datasheet PDF. This datasheet also covers the IS43LQ16256A variant, as both devices belong to the same 4gb mobile lpddr4/lpddr4x family and are provided as variant models within a single manufacturer datasheet.

General Description

The IS43/46LQ16256A/AL and IS43/46LQ32128A/AL are 4Gbit CMOS LPDDR4 SDRAM.

The device is organized as 1/2 channels per device, and each channel is 8-banks and 16-bits.

This product uses a double data rate architecture to achieve high-speed operation.

Key Features

  • Configuration: - 256Mb x16 x 1 channel - 128Mb x 16 x 2 channels - 8 internal banks per channel.
  • Low-voltage Core and I/O Power Supplies VDD1 = 1.70-1.95V 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.
  • Max. Clock Frequency : 1.6GHz (3.2Gbps).
  • 16n Pre-fetc.
