PRELIMINARY  
CY7C4231V/4241V/4251V  
Low Voltage 64/256/512/1K/2K/4K/8K x 9 Synchronous FIFOs  
• 32-pin PLCC  
Features  
Functional Description  
• High-speed, low-power, first-in, first-out (FIFO)  
memories  
The CY7C42X1V are high-speed, low-power, first-in first-out  
(FIFO) memories with clocked read and write interfaces. All  
are 9 bits wide. 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 interfaces, and communica-  
tions buffering.  
• 64 x 9 (CY7C4421V)  
• 256 x 9 (CY7C4201V)  
• 512 x 9 (CY7C4211V)  
• 1K x 9 (CY7C4221V)  
• 2K x 9 (CY7C4231V)  
• 4K x 9 (CY7C4241V)  
• 8K x 9 (CY7C4251V)  
These FIFOs have 9-bit input and output ports that are con-  
trolled by separate clock and enable signals. The input port is  
controlled by a free-running clock (WCLK) and two write-en-  
able pins (WEN1, WEN2/LD).  
• High-speed 66-MHz operation (15 ns read/write cycle  
time)  
• Low power (I = 20 mA)  
CC  
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  
CY7C42X1V 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 independently for  
asynchronous read/write applications. Clock frequencies up  
to 66 MHz are achievable.  
• 3.3V operation for low power consumption and easy  
integration into low voltage systems  
• 5V tolerant inputs V  
= 5V  
IH max  
• 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  
• Width Expansion Capability  
Depth expansion is possible using one enable input for sys-  
tem control, while the other enable is controlled by expansion  
logic to direct the flow of data  
• Space saving 32-pin 7mm x 7mm TQFP
