CY7C4231/4241/4251  
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 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 inter-  
faces, and communications buffering.  
64 × 9 (CY7C4421)  
256 × 9 (CY7C4201)  
512 × 9 (CY7C4211)  
1K × 9 (CY7C4221)  
2K × 9 (CY7C4231)  
4K × 9 (CY7C4241)  
8K × 9 (CY7C4251)  
These FIFOs have 9-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).  
High-speed 100-MHz operation (10 ns Read/Write cycle  
time)  
Low power (ICC = 35 mA)  
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  
Independent Read and Write enable pins  
Center power and ground pins for reduced noise  
Width-expansion capability  
Space saving 7 mm × 7 mm 32-pin TQFP  
32-pin PLCC  
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.  
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.  
Pin-compatible and functionally equivalent to  
IDT72421, 72201, 72211, 72221, 72231, and 72241
