CMOS SyncBiFIFO
256 x 18 x 2 and 512 x 18 x 2
FEATURES:
Two independent FIFO memories for fully bidirectional
data transfers
256 x 18 x 2 organization (IDT 72605)
512 x 18 x 2 organization (IDT 72615)
Synchronous interface for fast (20ns) read and write
cycle times
Each data port has an independent clock and read/write
control
Output enable is provided on each port as a three-state
control of the data bus
Built-in bypass path for direct data transfer between two
ports
Two fixed flags, Empty and Full, for both the A-to-B and
the B-to-A FIFO
Programmable flag offset can be set to any depth in the
FIFO
The synchronous BiFIFO is packaged in a 64-pin TQFP
(Thin Quad Flatpack), 68-pin PGA and 68-pin PLCC
Industrial temperature range (-40oC to +85oC) is avail-
able, tested to military electrical specifications
DESCRIPTION:
The IDT72605 and IDT72615 are very high-speed, low-
power bidirectional First-In, First-Out (FIFO) memories, with
synchronous interface for fast read and write cycle times. The
SyncBiFIFO
is a data buffer that can store or retrieve
information from two sources simultaneously. Two Dual-Port
FIFO memory arrays are contained in the SyncBiFIFO; one
data buffer for each direction.
The SyncBiFIFO has registers on all inputs and outputs.
Data is only transferred into the I/O registers on clock edges,
hence the interfaces are synchronous. Each Port has its own
independent clock. Data transfers to the I/O registers are
gated by the enable signals. The transfer direction for each
port is controlled independently by a read/write signal. Individ-
ual output enable signals control whether the SyncBiFIFO is
driving the data lines of a port or whether those data lines are
in a high-impedance state.
Bypass control allows data to be directly transferred from
input to output register in either direction.
The SyncBiFIFO has eight flags. The flag pins are full,
empty, almost-full, and almost-empty for both FIFO memo-
ries. The offset depths of the almost-full and almost-empty
flags can be programmed to any location.
The SyncBiFIFO is fabricated using IDT’s high-speed,
submicron CMOS technology.
