Integrated Silicon Solution (ISSI) has expanded its DDR2 SDRAM product family with the addition of a new 1 gigabit density. The first device at this new density is the IS43DR16640A that is organised as 64Mx16 and packaged in an 84-ball BGA.
The company said that the new product is available with clock speeds up to 533MHz, providing a data transfer rate of 4 gigabytes/sec in 32 bit systems.
In addition to this new 1Gb device, ISSI also offers 512Mb and 256Mb DDR2 devices, with all three densities available in commercial, industrial and automotive grades. The 256Mb density includes 8Mx32 and 16Mx16 organisations and for the 512Mb density 32Mx16 and 64Mx8 organisations are available.
ISSI said that it will add x8 versions of the 256Mb and 1Gb devices in the second quarter. The DDR2 DRAM product family operates from a single supply voltage of 1.8V.
The new device applications in networking and telecom include access nodes, aggregation nodes, VoIP, switches, routers and packet optical transport, while automotive applications include infotainment and telematics. Other applications are network storage, set-top boxes, DVRs and others, the company said.
Ron Kalakuntla, vice president of marketing at ISSI, said: “We continue to expand our DRAM product line to include a variety of interfaces, densities, organizations, and temperature ranges targeted for Automotive, Networking, Telecom, and Digital Consumer Applications.
The introduction of the 1 Gigabit density to our family of DDR2 SDRAM is an example of ISSI’s long-term commitment to support a complete range of high-quality DRAMs using leading-edge technology.”
ISSI also offers both asynchronous and synchronous SRAM with densities from 64Kb to 72Mb, in addition to SDR, mobile SDR/DDR, DDR and DDR2 SDRAMs.
Samples of the IS43DR16640A in both commercial and industrial temperature ranges are available with volume production shipments expected to begin in Q2, 2010.
