CY7C460A/CY7C462A  
CY7C464A/CY7C466A  
Asynchronous, Cascadable 8K/16K/32K/64K x9 FIFOs  
Features  
Functional Description  
• High-speed, low-power, first-in first-out (FIFO)  
memories  
• 8K x 9 FIFO (CY7C460A)  
• 16K x 9 FIFO (CY7C462A)  
• 32K x 9 FIFO (CY7C464A)  
• 64K x 9 FIFO (CY7C466A)  
• 10-ns access times, 20-ns read/write cycle times  
• High-speed 50-MHz read/write independent of  
depth/width  
• Low operating power  
— ICC= 60 mA  
The CY7C460A, CY7C462A, CY7C464A, and CY7C466A are  
respectively, 8K, 16K, 32K, and 64K words by 9-bit wide first-in  
first-out (FIFO) memories. 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 over-  
run 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 by passing tokens.  
The read and write operations may be asynchronous; each  
can occur at a rate of up to 50 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-imped-  
ance state when R is HIGH.  
— ISB =8 mA  
• Asynchronous read/write  
• Empty and Full flags  
• Half Full flag (in standalone mode)  
• Retransmit (in standalone mode)  
• TTL-compatible  
A Half Full (HF) output flag is provided that is valid in the stan-  
dalone (single device) and width expansion configurations. In  
the depth expansion configuration, this pin provides the ex-  
pansion out (XO) information that is used to tell the next FIFO  
that it will be activated.  
• Width and Depth Expansion Capability  
• 5V ± 10% supply  
• PLCC, LCC, 300-mil and 600-mil DIP packaging  
• Three-state outputs  
• Pin compatible density upgrade to CY7C42X/46X family  
• Pin compatible and functionally equivalent to IDT7205,  
IDT7206, IDT7207, IDT7208  
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 a retransmit cycle, and then R is used to access  
the data.  
The CY7C460A, CY7C462A, CY7C464A, and CY7C466A are  
fabricated using Cypress’s advanced 0.5µ RAM3 CMOS tech-  
nology. Input ESD protection is greater than 2000V and  
latch-up is prevented by careful layout and the use of guard  
rings.
