Integrated Silicon Solution Inc. (ISSI) is rolling out the latest members of its ultralow-power mobile SDRAM family, the 32Mbit SDR IS42VM16200C and the IS42VM32100C organized as 2Mx16 and 1Mx32 respectively and the DDR versions, the IS43LR16200C and the IS43LR32100C. These devices provide the lowest power consumption in the industry with an operating current of 50mA, standby current in power down mode of 80?A, and deep power down mode current of 10?A.

These devices have an operating voltage of 1.8V, a maximum speed of 166MHz and are supported in BGA package and KGD options. Both commercial and industrial temperature ranges are offered. The 32Mbit SDRAM devices add to ISSI's existing family of ultralow-lower mobile SDRAMs that include 64Mbit and 128Mbit SDR SDRAMs, as well as 32Mbit and 128Mbit DDR SDRAMs. ISSI also offers a 16Mbit SDR version as KGD.

"ISSI's ultralow-power mobile SDRAMs provide the designer with the right density using ultralow power technology designed to maximize performance in power sensitive applications," said Ron Kalakuntala, ISSI VP of marketing. "We will continue to expand this product line to provide our customers with the complete ultra low power mobile SDRAM solution."

The devices are designed for applications where both high performance and low power consumption are important, including mobile applications like GPS/navigation systems, smart phones, digital cameras, e-book readers, small form factor displays and gaming units. These devices also include power saving features such as Temperature Compensated Self Refresh that minimizes power consumption at lower temperatures; Partial Array Self Refresh that eliminates unnecessary row activations; and Deep Power Down mode that provides a low power state when data retention is not required.

Samples of the new 32Mbit ultralow-power mobile SDRAMs are available now with production quantities available in April. The 16-, 64- and 128Mbit ultralow-power mobile SDRAMs are all available in production now.
