ISSI readies first PSRAM line

Posted: 25 Feb 2008 ?? ?Print Version ?Bookmark and Share


Integrated Silicon Solution Inc. (ISSI) offers samples of the 4Mbit IS66WV25616BLL and the 8Mbit IS66WV51216BLL Pseudo SRAMs (PSRAM), the first members of its PSRAM product line.

The PSRAM combines the key features of SRAM and DRAM. With a pinout that is identical to regular 4Mbit and 8Mbit low-power SRAMs, these PSRAMs are drop in replacements for 4Mbit and 8Mbit SRAMs.

The IS66WV25616BLL and the IS66WV51216BLL are organized as 256KX16 and 512KX16 respectively, with access times of 55ns and typical operating current of 15mA. ISSI's PSRAMs are fabricated on 0.14?m DRAM technology and are available in commercial 0C to +70C and industrial -40C to 85C temperature ranges. Both 1.8V and 3.0V operating voltage versions are available.

The PSRAM product line is targeted at low power consumer, industrial, automotive, networking and telecom applications. Both devices are available in a 44-pin TSOPII package and in a 48-ball BGA package.

For quantities of 10,000, the IS66WV51216A/B, in a 44-pin TSOPII package with a 0C to 70C operating range, sells for $1.50. Samples are available now with volume production shipments beginning in Q2. Automotive versions of the IS66WV25616A/B and the IS66WV51216A/B will be available in the 2H.
