® CMOS STATIC RAM 64K (16K x 4-BIT) with Output Control IDT6198S IDT6198L Integrated Device Technology, Inc. FEATURES: High-speed (equal access and cycle times) — Military: 20/25/35/45/55/70/85ns (max.) — Commercial: 15/20/25/35ns (max.) Output Enable (OE) pin available for added system flexibility Low-power consumption JEDEC compatible pinout Battery back-up operation—2V data retention (L version only) 24-pin CERDIP, high-density 28-pin leadless chip carrier, and 24-pin SOJ Produced with advanced CMOS technology Bidirectional data inputs and outputs Military product compliant to MIL-STD-883, Class B DESCRIPTION: The IDT6198 is a 65,536-bit high-speed static RAM organized as 16K x 4. It is fabricated using IDT’s high-performance, high-reliability technology—CMOS. This state-of-theart technology, combined with innovative circuit design tech- niques, provides a cost-effective approach for memory intensive applications. Timing parameters have been specified to meet the speed demands of the IDT79R3000 RISC processors. Access times as fast as 15ns are available. The IDT6198 offers a reduced power standby mode, ISB1, which is activated when CS goes HIGH. This capability significantly decreases system, while enhancing system reliability. The low-power version (L) also offers a battery backup data retention capability where the circuit typically consumes only 30µW when operating from a 2V battery. All inputs and outputs are TTL-compatible and operate from a si...
