CY7C419/21/25/29/33256/512/1K/2K/4K  
x 9 Asynchronous FIFO  
CY7C419/21/25/29/33  
256/512/1K/2K/4K x 9 Asynchronous FIFO  
600-mil wide and 300-mil wide packages. They are, respec-  
tively, 256, 512, 1,024, 2,048, and 4,096 words by 9-bits wide.  
Features  
• Asynchronous first-in first-out (FIFO) buffer memories  
• 256 x 9 (CY7C419)  
Each FIFO memory is organized such that the data is read in  
the same sequential order that it was written. Full and Empty  
flags are provided to prevent overrun and underrun. Three  
additional pins are also provided to facilitate unlimited  
expansion in width, depth, or both. The depth expansion  
technique steers the control signals from one device to  
another in parallel, thus eliminating the serial addition of  
propagation delays, so that throughput is not reduced. Data is  
steered in a similar manner.  
• 512 x 9 (CY7C421)  
• 1K x 9 (CY7C425)  
• 2K x 9 (CY7C429)  
• 4K x 9 (CY7C433)  
• Dual-ported RAM cell  
The read and write operations may be asynchronous; each  
can occur at a rate of 50.0 MHz. The write operation occurs  
when the write (W) signal is LOW. Read occurs when read (R)  
goes LOW. The nine data outputs go to the high-impedance  
state when R is HIGH.  
• High-speed 50.0-MHz read/write independent of  
depth/width  
• Low operating power: ICC = 35 mA  
• Empty and Full flags (Half Full flag in standalone)  
• TTL compatible  
A Half Full (HF) output flag is provided that is valid in the  
standalone and width expansion configurations. In the depth  
expansion configuration, this pin provides the expansion out  
(XO) information that is used to tell the next FIFO that it will be  
activated.  
• Retransmit in standalone  
• Expandable in width  
• PLCC, 7x7 TQFP, SOJ, 300-mil and 600-mil DIP  
• Pb-Free Packages Available  
In the standalone and width expansion configurations, a LOW  
on the retransmit (RT) input causes the FIFOs to retransmit  
the data. Read enable (R) and write enable (W) must both be  
HIGH during retransmit, and then R is used to access the data.  
• Pin compatible and functionally equivalent to IDT7200,  
IDT7201, IDT7202, IDT7203, IDT7204, AM7200, AM7201,  
AM7202, AM7203, and AM7204  
The CY7C419, CY7C420, CY7C421, CY7C424, CY7C425,  
CY7C428, CY7C429, CY7C432, and CY7C433 are fabricated  
using an advanced 0.65-micron P-well CMOS technology.  
Input ESD protection is greater than 2000V and latch-up is  
prevented by careful layout and guard rings.  
Functional Description  
The CY7C419, CY7C420/1, CY7C424/5, CY7C428/9, and  
CY7C432/3 are first-in first-out (FIFO) memories offered in
