CY7C4265  
8K/16K x 18 Deep Sync FIFOs  
• Pb-Free Packages Available  
Features  
Functional Description  
• High-speed, low-power, first-in first-out (FIFO)  
memories  
The CY7C4255/65 are high-speed, low-power, first-in first-out  
(FIFO) memories with clocked read and write interfaces. All  
are 18 bits wide and are pin/functionally compatible to the  
CY7C42X5 Synchronous FIFO family. The CY7C4255/65 can  
be cascaded to increase FIFO depth. 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 commu-  
nications buffering.  
• 8K x 18 (CY7C4255)  
• 16K x 18 (CY7C4265)  
• 0.5 micron CMOS for optimum speed/power  
• High-speed 100-MHz operation (10-ns read/write cycle  
times)  
• Low power — ICC = 45 mA  
• Fully asynchronous and simultaneous read and write  
operation  
These FIFOs have 18-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 a Write  
Enable pin (WEN). When WEN is asserted, data is written into the  
FIFO on the rising edge of the WCLK signal. While WEN is held  
active, data is continually written into the FIFO on each cycle. The  
output port is controlled in a similar manner by a free-running Read  
Clock (RCLK) and a Read Enable pin (REN). In addition, the  
CY7C4255/65 have an Output Enable pin (OE). The read and write  
clocks may be tied together for single-clock operation or the two  
clocks may be run independently for asynchronous read/write appli-  
cations. Clock frequencies up to 100 MHz are achievable.  
• Empty, Full, HalfFull, andprogrammableAlmostEmpty  
and Almost Full status flags  
• TTL compatible  
• Retransmit function  
• Output Enable (OE) pins  
• 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  
Retransmit and Synchronous Almost Full/Almost Empty flag  
features are available on these devices.  
• Depth Expansion Capability  
Depth expansion is possible using the Cascade Input (WXI,  
RXI), Cascade Output (WXO, RXO), and First Load (FL) pins. The  
WXO and RXO pins are connected to the WXI and RXI pins of the  
next device, and the WXO and RXO pins of the last device should be  
connected to the WXI and RXI pins of the first device. The FL pin of  
the first device is tied to VSS and the FL pin of all the remaining  
• 64-pin TQFP and 64-pin STQFP  
• Pin-compatible density upgrade to CY7C42X5 family  
• Pin-compatible density upgrade to  
IDT72205/15/25/35/45  
devices should be tied to VCC
