CMOS Static RAM 16K (2K x 8-Bit) IDT6116SA IDT6116LA x Features High-speed access and chip select times – Military: 20/25/35/45/55/70/90/120/150ns (max.) – Industrial: 20/25/35/45ns (max.) – Commercial: 15/20/25/35/45ns (max.) Low-power consumption Battery backup operation – 2V data retention voltage (LA version only) Produced with advanced CMOS high-performance technology CMOS process virtually eliminates alpha particle soft-error rates Input and output directly TTL-compatible Static operation: no clocks or refresh required Available in ceramic and plastic 24-pin DIP, 24-pin Thin Dip, 24-pin SOIC and 24-pin SOJ Military product compliant to MIL-STD-833, Class B Description The IDT6116SA/LA is a 16,384-bit high-speed static RAM organized as 2K x 8. It is fabricated using IDT's high-performance, high-reliability CMOS technology. Access times as fast as 15ns are available. The circuit also offers a reduced power standby mode. When CS goes HIGH, the circuit will automatically go to, and remain in, a standby power mode, as long as CS remains HIGH. This capability provides significant system level power and cooling savings. The low-power (LA) version also offers a battery backup data retention capability where the circuit typically consumes only 1µW to 4µW operating off a 2V battery. All inputs and outputs of the IDT6116SA/LA are TTL-compatible. Fully static asynchronous circuitry is used, requiring no clocks or refreshing for operation. The IDT6116SA/LA is packaged in 24-pin 600 and 300 mil plastic or ceramic DIP, 24-lead gull-wing SOIC, and 24-lead J-bend SOJ providing high board-level packing densities. Military grade product is manufactured in compliance to the latest version of MIL-STD-883, Class B, making it ideally suited to military temperature applications demanding the highest level of performance and reliability. x x x x x x x x Functional Block Diagram A0 V CC ADDRESS DECODER A 10 128 X 128 MEMORY ARRAY GND I/O 0 INPUT DATA CIRCUIT I/O 7 I/O CONTROL , CS OE WE CONTROL CIRCUIT 3089 drw 01 FEBRUARY 2001 1 ©2000 Integrated Device Technology, Inc.

WE or CS must be HIGH during all address transitions. 2. A write occurs during the overlap of a LOW CS and a LOW WE. 3. tWR is measured from the earlier of CS or WE going HIGH to the end of the write cycle. 4. During this period, the I/O pins are in the output state and the input signals must not be applied. 5. If the CS LOW transition occurs simultaneously with or after the WE LOW transition, the outputs remain in the high-impedance state. 6. Transition is measured ±500mV from steady state. 7. OE is continuously HIGH. If OE is LOW during a WE controlled write cycle, the write pulse width must be the larger of tWP or (tWHZ + tDW) to allow the I/O drivers to turn off and data to be placed on the bus for the required tDW. If OE is HIGH during a WE controlled write cycle, this requirement does not apply and the write pulse is the specified tWP. For a CS controlled write cycle, OE may be LOW with no degradation to tCW. 6.42 9 IDT6116SA/LA CMOS Static RAM 2K (16K x 8-Bit) Military, Commercial, and In dustrial Temperature Ranges Ordering Information — Military IDT 6116 Device Type XX Power XXX Speed X Package X Process/ Temperature Range B Military (-55°C to +125°C) Compliant to MIL-STD-883, Class B TD D 300 mil CERDIP (D24-1) 600 mil CERDIP (D24-2) 20* 25* 35* 45 55 70 90 120 150** SA LA , Speed in nanoseconds Standard Power Low Power *Available in 300 mil packaging only. **Available in 600 mil packaging only. 3089 drw 11 Ordering Information — Commercial & Industrial IDT 6116 Device Type XX Power XXX Speed X Package X Process/ Temperature Range Blank I Commercial (0°C to +70°C) Industrial (-45°C to +85°C) TP P SO Y 300 mil Plastic DIP (P24-1) 600 mil Plastic DIP (P24-2) 300 mil Small Outline IC, Gull-Wing Bend (SO24-2) 300 mil SOJ, J-Bend (SO24-4) , 15* 20 25 35 45 Speed in nanoseconds SA LA Standard Power Low Power *Available in commercial temperature range and standard power only. 3089 drw 12 10 IDT6116SA/LA CMOS Static RAM 2K (16K x 8-Bit) Military, Commercial, and In dustrial Temperature Ranges Datasheet Document History 1/7/00 Pg. 1, 3, 4, 10 Pg. 9, 10 Pg. 11 08/09/00 02/01/01 Updated to new format Added Industrial Temperature range offerings Separated ordering information into military, commercial, and industrial temperature range offerings Added Datasheet Document History Not recommended for new designs Removed "Not recommended for new designs" CORPORATE HEADQUARTERS 2975 Stender Way Santa Clara, CA 95054 for SALES: 800-345-7015 or 408-727-6116 fax:408-492-8674 www.idt.com 6.42 11 for Tech Support: sramhelp@idt.com 800 544-7726, x4033 The IDT logo is a registered trademark of Integrated Device Technology, Inc.
