ꢀ
Integrated Real-Time Memory Array Solution  
The AS8S512K32 is a high speed, 5V, 16Mb SRAM. The  
device is available with access times of 12, 15, 20 and  
25ns creating a zero wait state/latency, real-time memory  
solution. The high speed, 5v supply voltage and control  
lines,make the device ideal for all your real-time computer  
memory requirements.

No latency or refresh cycles  
Parallel Read/Write Interface  
User Configurable via multiple enables  
Random Access Memory Array  
ꢀ
ꢀ
ꢀ
Fast Access Times: 12, 15, 20, and 25ns  
TTL Compatible I/O  
Fully Static, No Clocks  
The device can be configured as a 512K x 32 and used to  
create a single chip external data /program memory array  
solution or via use of the individual chip enable lines, be  
reconfigured as a 1M x 16 or 2M x 8.

68 Lead PLCC, No. 99 JEDEC M0-47AE  
Small Footprint, 0.990 Sq. In.  
Multiple Ground Pins for Maximum Noise Immunity  
Single +5V (±5%) Supply Operation  
The device provides a 50+% space savings when compared  
to four 512K x 8, 36 pin SOJs. In addition theAS8S512K32  
has only a 20pF load on the Addr. lines vs. ~30pF for four  
plastic SOJs.

*Stress greater than those listed under "Absolute Maximum Ratings"  
may cause permanent damage to the device. This is a stress rating  
only and functional operation of the device at these or any other  
conditions greater than those in di cated in the operational sections of  
this specification is not implied. Exposure to absolute maximum rating  
conditions for extended periods may affect reliability.
