CY7C4281  
CY7C4291  
64K/128K x 9 Deep Sync FIFOs  
Features  
Functional Description  
• High-speed, low-power, first-in first-out (FIFO)  
memories  
• 64K × 9 (CY7C4281)  
• 128K × 9 (CY7C4291)  
• 0.5-micron CMOS for optimum speed/power  
• High-speed 100-MHz operation (10-ns read/write cycle  
times)  
• Low power  
— ICC= 40 mA  
ISB = 2 mA  
The CY7C4281/91 are high-speed, low-power FIFO  
memories with clocked read and write interfaces. All are nine  
bits wide. The CY7C4281/91 are pin-compatible to the  
CY7C42X1 Synchronous FIFO family. Programmable  
features include Almost Full/Almost Empty flags. These FIFOs  
provide solutions for a wide variety of data buffering needs,  
including high-speed data acquisition, multiprocessor inter-  
faces, and communications buffering.  
These FIFOs have nine-bit input and output ports that are  
controlled by separate clock and enable signals. The input port  
is controlled by a free-running clock (WCLK) and two  
write-enable pins (WEN1, WEN2/LD).  
• Fully asynchronous and simultaneous read and write  
operation  
• Empty, Full, and programmable Almost Empty and  
Almost Full status flags  
• TTL compatible  
• Output Enable (OE) pin  
• Independent read and write enable pins  
• Center power and ground pins for reduced noise  
• Supports free-running 50% duty cycle clock inputs  
• Width Expansion Capability  
• 32-pin PLCC  
• Pin-compatible density upgrade to CY7C42X1  
family  
When WEN1 is LOW and WEN2/LD is HIGH, data is written  
into the FIFO on the rising edge of the WCLK signal. While  
WEN1, WEN2/LD is held active, data is continually written into  
the FIFO on each WCLK cycle. The output port is controlled in  
a similar manner by a free-running read clock (RCLK) and two  
read enable pins (REN1, REN2). In addition, the  
CY7C4281/91 has an output enable pin (OE). The read  
(RCLK) and write (WCLK) clocks may be tied together for  
single-clock operation or the two clocks may be run indepen-  
dently for asynchronous read/write applications. Clock  
frequencies up to 100 MHz are achievable. Depth expansion  
is possible using one enable input for system control, while the  
other enable is controlled by expansion logic to direct the flow  
of data.
