Santa Clara, Calif.--March 23, 1998--Integrated Device Technology, Inc. (Santa Clara, Calif.) introduced 1-Mbit and 512k Supersync FIFOs available in 3.3 V and announced its intent to continue pin compatibility in 4-Mbit FIFOs and beyond. Unlike 5-V FIFOs, which require additional conversion logic for use in today's 3.3-V system designs, the new IDT 1-Mbit Supersync FIFOs can provide a direct point-to-point interface between system microprocessors and ASIC devices operating at 3.3 V.
Developed as depth extensions of IDT's popular Supersync family, first introduced in 1992, the 1-Mbit IDT72V285 (64k ( 18) and IDT72V291 (128k ( 9) both support the features and performance of legacy Supersync FIFOs.
Also available are 3.3-V versions of 512k density FIFOs in (18 and (9 configurations, as well as 5.0-V versions for use in system designs where a 3.3-V specification is not a primary requirement. The 5-V versions are offered in single-package configurable organizations and achieve 6.5-ns access times, enabling true 100-MHz system designs.
IDT's 3.3-V Supersync 1-Mbit IDT72V285/V291 FIFOs are priced at $49.50 in 10,000-piece quantities and the 512k Supersync IDT72V275/V281 FIFOs are priced at $38 in 10,000-piece quantities. All devices are available in either 64-pin STQFP or TQFP packages. Samples are available in April with volume production following in June of this year. Supersync 3.3-V FIFOs of 2- and 4-Mbit densities are planned for release later this year.
