The company has said that these devices provide low power consumption with an operating current of 50mA, standby current in power down mode of 80uA, and deep power down mode current of 10uA.
These 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. Both commercial and industrial temperature ranges are offered.
The 32Mb SDRAM devices add to ISSI’s existing family of ultra low power Mobile SDRAMs that include 64Mb and 128Mb SDR SDRAMs, and 32Mb and 128Mb DDR SDRAMs. ISSI also offers a 16Mb SDR version as Known Good Die (KGD).
ISSI said that its ultra low power Mobile SDRAM products are suitable 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.
The company claimed that these devices have Temperature Compensated Self Refresh (TCSR) feature that minimizes power consumption at lower temperatures, Partial Array Self Refresh (PASR) feature that eliminates unnecessary row activations. Furthermore, its Deep Power Down mode (DPD) provides 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 maximize 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.”
