CY7C4261  
CY7C4271  
entering or exiting the Empty and Almost Empty states, the  
flags are updated exclusively by the RCLK. The flags denoting  
Almost Full, and Full states are updated exclusively by WCLK.  
The synchronous flag architecture guarantees that the flags  
maintain their status for at least one cycle.  
Functional Description (continued)  
The CY7C4261/71 provides four status pins: Empty, Full,  
Programmable Almost Empty, and Programmable Almost Full.  
The Almost Empty/Almost Full flags are programmable to  
single word granularity. The programmable flags default to  
Empty + 7 and Full – 7.  
All configurations are fabricated using an advanced 0.5µ  
CMOS technology. Input ESD protection is greater than  
2001V, and latch-up is prevented by the use of guard rings.  
The flags are synchronous, i.e., they change state relative to  
either the read clock (RCLK) or the write clock (WCLK). When

Description  
Data Inputs

I
Data Inputs for 9-bit bus.  
Q0−8  
Data Outputs  
Write Enable 1  
Data Outputs for 9-bit bus.  
WEN1  
The only write enable when device is configured to have programmable flags. Data  
is written on a LOW-to-HIGH transition of WCLK when WEN1 is asserted and FF is HIGH.  
If the FIFO is configured to have two write enables, data is written on a LOW-to-HIGH  
transition of WCLK when WEN1 is LOW and WEN2/LD and FF are HIGH.  
WEN2/LD  
Dual Mode Pin  
Write Enable 2  
Load  
I
If HIGH at reset, this pin operates as a second write enable. If LOW at reset, this pin  
operates as a control to write or read the programmable flag offsets. WEN1 must be LOW  
and WEN2 must be HIGH to write data into the FIFO. Data will not be written into the  
FIFO if the FF is LOW. If the FIFO is configured to have programmable flags, WEN2/LD  
is held LOW to write or read the programmable flag offsets.  
REN1, REN2 Read Enable  
Inputs  
I
I
Enables the device for Read operation. Both REN1 and REN2 must be asserted to  
allow a read operation.  
WCLK  
Write Clock  
The rising edge clocks data into the FIFO when WEN1 is LOW and WEN2/LD is HIGH  
and the FIFO is not Full. When LD is asserted, WCLK writes data into the programmable  
flag-offset register.  
RCLK  
Read Clock  
I
The rising edge clocks data out of the FIFO when REN1 and REN2 are LOW and the  
FIFO is not Empty. When WEN2/LD is LOW, RCLK reads data out of the programmable  
flag-offset register.  
EF  
Empty Flag  
Full Flag  
O
O
O
When EF is LOW, the FIFO is empty. EF is synchronized to RCLK.  
When FF is LOW, the FIFO is full. FF is synchronized to WCLK.  
FF  
PAE  
Programmable  
Almost Empty  
When PAE is LOW, the FIFO is almost empty based on the almost empty offset  
value programmed into the FIFO. PAE is synchronized to RCLK.  
PAF  
RS  
Programmable  
Almost Full  
O
I
When PAF is LOW, the FIFO is almost full based on the almost full offset value  
programmed into the FIFO. PAF is synchronized to WCLK.  
Reset  
Resets device to empty condition. A reset is required before an initial read or write  
operation after power-up.  
OE  
Output Enable  
I
When OE is LOW, the FIFO’s data outputs drive the bus to which they are  
connected. If OE is HIGH, the FIFO’s outputs are in High Z (high-impedance) state.
