ADVANCE INFORMATION AS6nvLC512K8 AS6nvLC256K16 512K x 8 / 256K x 16 nvSRAM 3.3V High Speed SRAM with Non-Volatile Storage FEATURES -55oC to 125oC Operation True non-volatile SRAM (no batteries) 20 ns, 25 ns, and 45 ns access times Automatic STORE on power down with only a small capacitor nvSRAM AVAILABLE AS MILITARY SPECIFICATIONS Military Processing (MIL-STD-883C para 1.2.2) Temperature Range -55C to 125C FUNCTIONAL DESCRIPTION The AS6nvLC512K8 / AS6nvLC256K16 is a fast static RAM, with a nonvolatile element in each memory cell. The memory is organized as 512K bytes of 8 bits each or 256K words of 16 bits each. The embedded nonvolatile elements incorporate QuantumTrap technology, producing the world’s most reliable nonvolatile memory. The SRAM provides infinite read and write cycles, while independent nonvolatile data resides in the highly reliable QuantumTrap cell. Data transfers from the SRAM to the nonvolatile elements (the STORE operation) takes place automatically at power down. On power up, data is restored to the SRAM (the RECALL operation) from the nonvolatile memory. Both the STORE and RECALL operations are also available under software control. STORE to QuantumTrap® nonvolatile elements initiated by software, device pin, or AutoStore® on power down RECALL to SRAM initiated by software or power up Infinite Read, Write, and Recall cycles 200,000 STORE cycles to QuantumTrap 20 year data retention Single 3.3V +.3V/-3V operation Ceramic H...
