ISSI unveils 32Mb ultra low power mobile SDRAMs

Supported in BGA package and Known Good Die options

Integrated Silicon Solution (ISSI) has expanded its ultra low power mobile SDRAM family with the launch of 32Mb SDR IS42VM16200C and the IS42VM32100C organised as 2Mx16 and 1Mx32 respectively and the DDR versions IS43LR16200C and IS43LR32100C.

The company claims that the new devices provide the lowest power consumption with an operating current of 50mA, standby current in power down mode of 80uA, and deep power down mode current of 10uA.

According to ISSI, the new devices have an operating voltage of 1.8V, a maximum speed of 166Mhz and are supported in BGA package and Known Good Die (KGD) options.

The 32Mb SDRAM devices add to the company's existing family of ultra low power Mobile SDRAMs that include 64Mb and 128Mb SDR SDRAMs, and 32Mb and 128Mb DDR SDRAMs. The company also offers a 16Mb SDR version as Known Good Die (KGD).

The company said that its Mobile SDRAM products include power saving features such as temperature compensated self refresh (TCSR) that minimises power consumption at lower temperatures; partial array self refresh (PASR) that eliminates unnecessary row activations; and deep power down mode (DPD) to provide a low power state when data retention is not required.

Ron Kalakuntala, vice president of marketing at ISSI, said: ISSI's ultra low power Mobile SDRAMs provide the designer with the right density using ultra low power technology designed to maximise performance in power sensitive applications. We will continue to expand this product line to provide our customers with the complete ultra low power Mobile SDRAM solution.
