64/256/512/1K/2K/4K/8K x 9 Synchronous FIFOs  
Features  
Functional Description  
• High-speed, low-power, first-in, first-out (FIFO)  
memories  
THe CY7C42X1 are high-speed, low-power, first-in first-out  
(FIFO) memories with clocked read and write interfaces. All  
are 9 bits wide. The CY7C42X1 are pin-compatible to  
IDT722X1. 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 communications buffering.  
• 64 x 9 (CY7C4421)  
• 256 x 9 (CY7C4201)  
• 512 x 9 (CY7C4211)  
• 1K x 9 (CY7C4221)  
• 2K x 9 (CY7C4231)  
• 4K x 9 (CY7C4241)  
• 8K x 9 (CY7C4251)  
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 100-MHz operation (10 ns read/write cycle  
time)  
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 CY7C42X1  
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 100 MHz are  
achievable.  
• Low power (I = 35 mA)  
CC  
• Fully asynchronous and simultaneous read and write  
operation  
• Empty, Full, and Programmable Almost Empty and  
Almost Full status flags  
• TTL-compatible  
• Expandable in width  
• Output Enable (OE) pin  
• Independant read and write enable pins  
• Center power and ground pins for reduced noise  
• Width Expansion Capability  
• Space saving 7mm x 7mm 32-pin TQFP  
• 32-pin PLCC  
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.
