The IDT6198S 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 IDT6198S 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 30mW when operating from a 2V battery.
All inputs and outputs are TTL-compatible and operate from a single 5V supply.
The IDT6198 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 IDT6198S, Class B, making it ideally suited to military temperature applications demanding the highest level of performance and reliability.
