iPEM  
16 Mb ASYNC SRAM  
AS8SLC512K32PECA  
16Mb, 512Kx32 CMOS 3.3V, High Speed Static RAM  
Integrated Plastic Encapsulated Microcircuit  
FEATURES  
DESCRIPTION  
Integrated Real-Time Memory Array Solution  
The AS8SLC512K32 is a high speed, 3.3V, 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, 3.3V supply voltage  
and control lines,make the device ideal for all your  
real-time computer memory requirements.  
No latency or refresh fycles  
Parallel Read/Write Interface  
User Congurable 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 congured 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  
recongured as a 1M x 16 or 2M x 8.  
Surface Mount Package  
68 Lead PLCC, No. 99 JEDEC M0-47AE  
Small Footprint, 0.990 Sq. In.  
Multiple Ground Pins for Maximum Noise Immunity  
Single 3.3V (±10%) Supply Operation  
The device provides a 50+% space savings when  
compared to four 512K x 8, 36 pin SOJs. In addition the  
AS8SLC512K32 has only a 24pF load on the Addr. lines  
vs. ~40pF for four plastic SOJs.
