| i PEM 16 MB ASYNC SRAM Austin Semiconductor, Inc. AS8S512K32PEC 16Mb, 512Kx32 CMOS 5.0V, High Speed Static RAM Integrated Plastic Encapsulated Microcircuit FEATURES Integrated Real-Time Memory Array Solution No latency or refresh fycles 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 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 +5V (5%) Supply Operation DESCRIPTION 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. 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. The device provides a 50+% space savings when compared to four 512K x 8, 36 pin SOJs. In addition the AS8S512K32 has only a 20pF load on the Addr. lines vs. ~30pF for four plastic SOJs.
