CY7C130, CY7C130A  
CY7C131, CY7C131A  
CY7C140, CY7C141  
1K x 8 Dual-Port Static RAM  
Features  
Functional Description  
True dual-ported memory cells, which allow simultaneous  
reads of the same memory location  
The CY7C130/130A/CY7C131/131A/CY7C140[1] and CY7C141  
are high speed CMOS 1K by 8 dual-port static RAMs. Two ports  
are provided permitting independent access to any location in  
memory. The CY7C130/130A/ CY7C131/131A can be used as  
either a standalone 8-bit dual-port static RAM or as a master  
dual-port RAM in conjunction with the CY7C140/CY7C141 slave  
dual-port device in systems requiring 16-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 multi-  
processor designs.  
1K x 8 organization  
0.65 micron CMOS for optimum speed and power  
High speed access: 15 ns  
Low operating power: ICC = 110 mA (maximum)  
Fully asynchronous operation  
Each port has independent control pins; chip enable (CE), write  
enable (R/W), and output enable (OE). Two flags are provided  
on each port, BUSY and INT. BUSY signals that the port is trying  
to access the same location currently being accessed by the  
other port. INT is an interrupt flag indicating that data is placed  
in a unique location (3FF for the left port and 3FE for the right  
port). An automatic power down feature is controlled indepen-  
dently on each port by the chip enable (CE) pins.  
Automatic power down  
Master CY7C130/130A/CY7C131/131A easily expands data  
bus width to 16 or more bits using slave CY7C140/CY7C141  
BUSY output flag on CY7C130/130A/CY7C131/131A; BUSY  
input on CY7C140/CY7C141  
INT flag for port-to-port communication  
The CY7C130/130A and CY7C140 are available in 48-pin DIP.  
The CY7C131/131A and CY7C141 are available in 52-pin  
PLCC, 52-pin Pb-free PLCC, 52-pin PQFP, and 52-pin Pb-free  
PQFP.  
Available in 48-pin DIP (CY7C130/130A/140), 52-pin PLCC,  
52-pin TQFP  
Pb-free packages available

Notes  
1. CY7C130 and CY7C130A are functionally identical; CY7C131 and CY7C131A are functionally identical.  
2. CY7C130/130A/CY7C131/131A (Master): BUSY is open drain output and requires pull-up resistor.  
CY7C140/CY7C141 (Slave): BUSY is input.  
3. Open drain outputs: pull-up resistor required.
