Pin Configurations
Functional Description
The CY7C4275/85 provides five status pins. These pins are decod-
ed to determine one of five states: Empty, Almost Empty, Half Full,
Almost Full, and Full (see Table 2). The Half Full flag shares the
WXO pin. This flag is valid in the stand-alone and width-expansion
configurations. In the depth expansion, this pin provides
the expansion out (WXO) information that is used to signal
the next FIFO when it will be activated.

The Empty and Full 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 states, the flag is
updated exclusively by the RCLK. The flag denoting Full states
is updated exclusively by WCLK. The synchronous flag archi-
tecture guarantees that the flags will remain valid from one
clock cycle to the next. The Almost Empty/Almost Full flags
become synchronous if the V
configurations are fabricated using an advanced 0.5
CMOS technology. Input ESD protection is greater than
2001V, and latch-up is prevented by the use of guard rings.
