FEATURES  
FUNCTIONAL DESCRIPTION  
-55oC to 125oC Operation  
The Austin Semiconductor AS8nvLC512K32 is a fast static RAM,  
with a nonvolatile element in each memory cell. The memory is  
organized as 512K bytes of 8 bits for each of 4 die to form 512Kx32.  
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.  
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  
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 +/- 0.3V operation  
Ceramic Hermetic 68 Quad Flatpak  
-Can order with X7R CAPS on package  
-Matches compatible pinout footprint of SRAM & EEPROM
