IS43LD32128B - 4Gb (x32) Mobile LPDDR2 S4 SDRAM

Download the IS43LD32128B datasheet PDF. This datasheet also covers the IS46LD32128B variant, as both devices belong to the same 4gb (x32) mobile lpddr2 s4 sdram family and are provided as variant models within a single manufacturer datasheet.

Description

The IS43/46LD32128B is 4Gbit CMOS LPDDR2 DRAM.

The device is organized as 8 banks of 16Meg words of 32bits.

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

Features

  • DDP (Dual Die Package) with 2 x 2Gb LPDDR2.
  • Low-voltage Core and I/O Power Supplies VDD2 = 1.14-1.30V, VDDCA/VDDQ = 1.14-1.30V, VDD1 = 1.70-1.95V.
  • High Speed Un-terminated Logic(HSUL_12) I/O Interface.
  • Clock Frequency Range : 10MHz to 533MHz (data rate range : 20Mbps to 1066Mbps per I/O).
  • Four-bit Pre-fetch DDR Architecture.
  • Multiplexed, double data rate, command/address inputs.
  • Eight internal banks for concurrent operation.
