Functional Description
The CY7C4282V/92V provides four status pins: Empty, Full,
Programmable Almost Empty, and Programmable Almost Full.
The Almost Empty/Almost Full flags are programmable to sin-
gle word granularity. The programmable flags default to Emp-
ty+7 and Full 7.
The flags are synchronous, i.e., they change state relative to
either the read clock (RCLK) or the write clock (WCLK). When

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
All configurations are fabricated using an advanced 0.35
CMOS technology. Input ESD protection is greater than
2001V, and latch-up is prevented by the use of guard rings.
