1CYM1481A  
CYM1481A  
2048K x 8 SRAM Module  
are constructed from four 512K x 8 SRAMs in plastic sur-  
face-mount packages on an epoxy laminate board with pins.  
On-board decoding selects one of the SRAMs from the  
high-order address lines, keeping the remaining devices in  
standby mode for minimum power consumption.  
Features  
• High-density 16-megabit SRAM modules  
• High-speed CMOS SRAMs  
— Access time of 70 ns  
• Low active power  
An active LOW write enable signal (WE) controls the writ-  
ing/reading operation of the memory. When MS and WE inputs  
are both LOW, data on the eight data input/output pins is writ-  
ten into the memory location specified on the address pins.  
Reading the device is accomplished by selecting the device  
and enabling the outputs MS and OE active LOW while WE  
remains inactive or HIGH. Under these conditions, the content  
of the location addressed by the information on the address  
pins is present on the eight data input/output pins.  
— 605 mW (max.), 2M x 8  
• Double-sided SMD technology  
• TTL-compatible inputs and outputs  
• Small footprint SIP  
— PCB layout area of 0.72 sq. in.  
• 2V data retention (L version)  
Functional Description  
The input/output pins remain in a high-impedance state unless  
the module is selected, outputs are enabled, and write enable  
(WE) is HIGH.  
The CYM1481A is a high-performance 16-megabit static RAM  
module organized as 2048K words by 8 bits. These modules
