Integrated Silicon Solution Inc. is expanding its family of DDR2 SDRAMs with a 512Mbit device. The IS43DR16320B is organized as 32Mx16 and is available in an 84-ball BGA package.

The IS43DR16320B is available with clock speeds up to 400MHz (DDR2-800), providing a data transfer rate of 3GByte/s in 32bit systems. In addition to the 512Mbit device, ISSI offers 256Mbit DDR2 devices, with both densities available in commercial, industrial and automotive grades. The 256Mbit density devices include 8Mx32 and 16Mx16 organizations. In Q1 10, ISSI will add 1Gbit devices organized as 64Mx16 and 128Mx8 as well as x8 versions of the 256Mbitit and 512Mbit devices. The DDR2 DRAM product family operates from a single supply voltage of 1.8V.

"DDR2 SDRAMs are being introduced in order to support the needs of our strategic customer base. Expanding our DDR2 SDRAM product offering is part of ISSI's long-term commitment to support a complete range of high-quality DRAMs using leading-edge technology," said Ron Kalakuntla, VP of marketing, ISSI. "We will continue to invest in our DRAM product line to include a variety of interfaces, densities, organizations, and temperature ranges targeted for automotive, networking, telecom, and digital consumer applications." Key applications in networking and telecom include access nodes, aggregation nodes, VoIP, switches, routers, and packet optical transport. Automotive applications are infotainment and telematics. Other applications include network storage, STBs, DVRs and others.

For quantities of 10,000, the IS43DR16320B, in an 84-ball BGA package with a commercial operating temperature range of 0C to 85C(Tcase), is priced at $5. Samples are available now with volume production shipments beginning in Q1 10. Samples of the automotive version, the IS46DR16320B, are also available.
