IDT72255/72265 SyncFIFO
8,192 x 18, 16,384 x 18
MILITARY AND COMMERCIAL TEMPERATURE RANGES
gramming offset registers may not be convenient.
The Retransmit function allows the read pointer to be reset
to the first location in the RAM array. It is synchronized to
RCLK when
RT
is LOW. This feature is convenient for
sending the same data more than once.
If, at any time, the FIFO is not actively performing a function,
the chip will automatically power down. This occurs if neither
a read nor a write occurs within 10 cycles of the faster clock,
RCLK or WCLK. During the Power Down state, supply current
consumption (I
CC2
) is at a minimum. Initiating any operation
(by activating control inputs) will immediately take the device
out of the Power Down state.
The IDT72255/72265 are depth expandable. The addition
of external components is unnecessary. The
IR
and
OR
functions, together with
REN
and
WEN
, are used to extend the
total FIFO memory capacity.
The FS line ensures optimal data flow through the FIFO. It
is tied to GND if the RCLK frequency is higher than the WCLK
frequency or to Vcc if the RCLK frequency is lower than the
WCLK frequency
The IDT72255/72265 is fabricated using IDT’s high speed
submicron CMOS technology.
