CY7C132/CY7C136  
CY7C142/CY7C146  
2Kx8 Dual-Port Static RAM  
Features  
Functional Description  
• True Dual-Ported memory cells which allow simulta-  
neous reads of the same memory location  
• 2K x 8 organization  
• 0.65-micron CMOS for optimum speed/power  
• High-speed access: 15 ns  
The CY7C132/CY7C136/CY7C142 and CY7C146 are  
high-speed CMOS 2K by 8 dual-port static RAMs. Two ports  
are provided to permit independent access to any location in  
memory. The CY7C132/ CY7C136 can be utilized as either a  
standalone 8-bit dual-port static RAM or as a MASTER du-  
al-port RAM in conjunction with the CY7C142/CY7C146  
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  
multiprocessor designs.  
• Low operating power: I = 90 mA (max.)  
CC  
• Fully asynchronous operation  
• Automatic power-down  
• Master CY7C132/CY7C136 easily expands data bus  
width to 16 or more bits using slave CY7C142/CY7C146  
• BUSY output flag on CY7C132/CY7C136; BUSY input  
on CY7C142/CY7C146  
• INT flag for port-to-port communication (52-pin  
PLCC/PQFP versions)  
• Availablein 48-pin DIP (CY7C132/142), 52-pin PLCCand  
52-pin TQFP (CY7C136/146)  
• Pin-compatible and functionally equivalent to  
IDT7132/IDT7142  
Each port has independent control pins; chip enable (CE),  
write enable (R/W), and output enable (OE). BUSY flags are  
provided on each port. In addition, an interrupt flag (INT) is  
provided on each port of the 52-pin PLCC version. BUSY sig-  
nals that the port is trying to access the same location currently  
being accessed by the other port. On the PLCC version, INT  
is an interrupt flag indicating that data has been placed in a  
unique location (7FF for the left port and 7FE for the right port).  
An automatic power-down feature is controlled independently  
on each port by the chip enable (CE) pins.  
The CY7C132/CY7C142 are available in 48-pin DIP. The  
CY7C136/CY7C146 are available in 52-pin PLCC and PQFP.

Notes:  
1. CY7C132/CY7C136 (Master): BUSY is open drain output and requires pull-up resistor.  
CY7C142/CY7C146 (Slave): BUSY is input.  
2. Open drain outputs; pull-up resistor required.
