• Pb-Free Packages Available  
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)  
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.  
• 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  
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.  
• Space saving 7 mm × 7 mm 32-pin TQFP  
• Pin-compatible and functionally equivalent to  
IDT72421, 72201, 72211, 72221, 72231, and 72241
