IS46LD32320C - 1Gb Mobile LPDDR2 S4 SDRAM

Download the IS46LD32320C datasheet PDF. This datasheet also covers the IS43LD16640C variant, as both devices belong to the same 1gb mobile lpddr2 s4 sdram family and are provided as variant models within a single manufacturer datasheet.

General Description

The IS43/46LD16640C/32320C is 1Gbit CMOS LPDDR2 DRAM.

The device is organized as 8 banks of 8Meg words of 16bits or 4Meg words of 32bits.

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

Key Features

  • 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.
  • Bidirectional/differential data strobe per byte of.
