K / 2 K × 8 Dual-port Static RAM  
Features  
Functional Description  
True dual-ported memory cells, which allow simultaneous  
reads of the same memory location  
CY7C131E / CY7C131AE / CY7C136E / CY7C136AE are  
high-speed, low-power CMOS 1 K / 2 K × 8 dual-port static  
RAMs. Two ports are provided permitting independent access to  
any location in memory. The CY7C131E / CY7C131AE /  
CY7C136E / CY7C136AE can be used as a standalone dual-port  
static RAM. It is the solution to applications requiring shared or  
buffered data, such as cache memory for DSP, bit-slice, or multi-  
processor designs.  
1 K / 2 K × 8 organization  
0.35 micron complementary metal oxide semiconductor  
(CMOS) for optimum speed and power  
High speed access: 15 ns  
Low operating power: ICC = 110 mA (typical),  
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. The BUSY flag signals that the port  
is trying to access the same location, which is currently being  
accessed by the other port. The INT is an interrupt flag indicating  
that data is placed in a unique location[1]. The BUSY and INT  
flags are push pull outputs. An automatic power-down feature is  
controlled independently on each port by the chip enable (CE)  
pins.  
Standby: ISB3 = 0.05 mA (typical)  
Fully asynchronous operation  
Automatic power-down  
BUSY output flag to indicate access to the same location by  
both ports  
INT flag for port-to-port communication  
Available in 52-pin plastic leaded chip carrier (PLCC), 52-pin  
plastic quad flat package (PQFP)  
The CY7C131E / CY7C131AE / CY7C136E / CY7C136AE are  
available in 52-pin Pb-free PLCC and 52-pin Pb-free PQFP.  
Pb-free packages available

Notes  
1. Unique location used by interrupt flag: 1 K × 8: Left port reads from 3FE, Right port reads from 3FF; 2 K × 8: Left port reads from 7FE, Right port reads from 7FF.  
2. BUSY is a push-pull output. No pull-up resistor required.  
3. INT: push-pull output. No pull-up resistor required.  
4. 1 K × 8: A0–A9, 2 K × 8: A0–A10, address lines are for both left and right ports.
