| CMOS Static RAM 256K 32K x 8-Bit IDT71256S IDT71256L High-speed address/chip select time Military 25/35/45/55/70/85/100ns max. Industrial 25/35ns max. Commercial 20/25/35ns max. low power only Low-power operation Battery Backup operation 2V data retention Produced with advanced high-performance CMOS technology Input and output directly TTL-compatible Available in standard 28-pin 300 or 600 mil ceramic DIP, 28-pin 600 mil plastic DIP, 28-pin 300 mil SOJ and 32-pin LCC Military product compliant to MIL-STD-883, Class B Functional Block Diagram The IDT 71256 is a 262,144-bit high-speed static RAM organized as 32K x It is fabricated using IDT's high-performance, high-reliability CMOS technology. Address access times as fast as 20ns are available with power consumption of only 350mW typ. . The circuit also offers a reduced power standby mode. When CS goes HIGH, the circuit will automatically go to and remain in, a low-power standby mode as long as CS remains HIGH. In the full standby mode, the low-power device consumes less than 15µW, typically. This capability provides significant system level power and cooling savings. The low-power L version also offers a battery backup data retention capability where the circuit typically consumes only 5µW when operating off a 2V battery. The IDT71256 is packaged in a 28-pin 300 or 600 mil ceramic DIP, a 28-pin 300 mil SOJ, a 28-pin 600 mil plastic DIP, and a 32-pin LCC providing high board level packing densities.
