NOTE: 1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.DescriptionThe IDT6198L 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 techniques, 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 IDT6198L 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 30mW when operating from a 2V battery.
All inputs and outputs are TTL-compatible and operate from a single 5V supply.
The IDT6198L is packaged in either a 24-pin 300 mil CERDIP, 28-pin leadless chip carrier or 24-pin J-bend small outline IC.
Military grade product is manufactured in compliance with the latest revision of MIL-STD-883, Class B, making it ideally suited to military temperature applications demanding the highest level of performance and reliability.
