CY7C133  
CY7C143  
2K x 16 Dual-Port Static RAM  
Features  
Functional Description  
True dual-ported memory cells which allow  
The CY7C133 and CY7C143 are high-speed CMOS 2K by 16  
dual-port static RAMs. Two ports are provided permitting  
independent access to any location in memory. The CY7C133  
can be utilized as either a stand-alone 16-bit dual-port static  
RAM or as a master dual-port RAM in conjunction with the  
CY7C143 slave dual-port device in systems requiring 32-bit or  
greater word widths. It is the solution to applications requiring  
shared or buffered data, such as cache memory for DSP,  
bit-slice, or multiprocessor designs.  
simultaneous reads of the same memory location  
2K x 16 organization  
0.65-micron CMOS for optimum speed/power  
High-speed access: 25/35/55 ns  
Low operating power: ICC = 150 mA (typ.)  
• Fully asynchronous operation  
Master CY7C133 expands data bus width to 32 bits or  
more using slave CY7C143  
BUSY output flag on CY7C133; BUSY input flag on  
CY7C143  
Available in 68-pin PLCC  
Each port has independent control pins; Chip Enable (CE),  
Write Enable (R/WUB, R/WLB), and Output Enable (OE).  
BUSY signals that the port is trying to access the same  
location currently being accessed by the other port. An  
automatic power-down feature is controlled independently on  
each port by the Chip Enable (CE) pin.  
The CY7C133 and CY7C143 are available in 68-pin PLCC.
