A: GSI is sampling all varieties of GS832A memories today. Please contact your local GSI sales representative for pricing and delivery. SyncBurst™ datasheets are available at http://www.gsitechnology.com/syncburst_36Mb.htm; NBT™ datasheets are available at http://www.gsitechnology.com/NBT_36Mb.htm. Q: What does the ”A” in the part number indicate? A: The “A” represents a technology shrink with no significant circuit changes. The primary benefits are lower power consumption and speed increases of up to 400 MHz. Q: What does the ”G” in the part number indicate? A: The “G” indicates the package is 6/6 RoHS-compliant—commonly referred to as “green”. GSI also offers these products in 5/6 RoHS-compliant 119 BGA, 165 BGA and 209 BGA packages. Q: I’m using GSI’s original GS832 memories today and can’t afford to qualify a new board. How long will GSI support the original family? A: GSI has a policy of extended product life support for mature devices after a replacement is qualified. A reasonable expectation is another 12–18 months of production before any EOL notice is issued, plus a generous time horizon for final orders and shipments. Q: What temperature ranges are available? A: GSI offers commercial (TJ: 0 to 85⁰C) and industrial (TJ : –40 to +100⁰C) temperature range for all memories as standard products. GSI also offers a wide variety of synchronous SRAMs for mil-temp applications. A complete list can be seen at http://www.gsitechnology.com/Patton/Mil_Temp_Brochure.pdf Q: Are second sources available? A: Yes. SyncBurst™ and NBT™ memories are designed to be compatible with products from a variety of providers. Q: What silicon technology is used? A: GS832A memories use TSMC’s standard C65LP wafer process. It is qualified and in high volume production at multiple fabs. Yields are mature and stable. Q: Does GSI offer model files? A: Yes. GSI offers Verilog, BSDL, VHDL and IBIS models with each device. Spice models are available under NonDisclosure Agreement.
