FEATURES:
Two independent FIFOs (64 X 36 storage capacity each) buffer
data between bidirectional 36-bit port A and two unidirectional
18/9-bit ports (Port B transmits, Port C receives)
Clock frequencies up to 67 MHz (10 ns access time)
Free-running clock lines for each port: CLKA, CLKB and CLKC,
may be asynchronous or coincident (simultaneous reading and
writing of data is permitted)
IDT Standard timing
Empty flag functions: EFA (synchronized by CLKA) and EFB
(synchronized by CLKB)
Full flag functions: FFA (synchronized by CLKA) and FFC
(synchronized by CLKC)
Programmable Almost-Empty and Almost-Full flags; each has
four default offsets (4, 8, 12 and 16)
Bus sizing of 18-bits (word) and 9-bits (byte) for ports B and C
Byte order swapping on ports B and C
Passive parity checking on ports A and C
Parity generation can be selected for ports A and B
Master Reset clears data and configures FIFO
Width can be easily expanded by adding FIFOs
Auto power down minimizes power dissipation
Available in a space-saving 128-pin Thin Quad Flatpack (TQFP)
High performance sub-micron CMOS technology
Industrial temperature range (–40oC to +85oC) is available
Green parts available, see ordering information
DESCRIPTION:
The IDT723616 is a monolithic, high-speed, low-power, CMOS Triple Bus
SyncFIFO
(clocked) memory which supports clock frequencies up to 67
MHz and has read access times as fast as 10 ns. Two independent 64 x 36
dual-port SRAM FIFOs on board each chip buffer data between a bidirectional
36-bit bus (Port A) and two unidirectional 18-bit buses (Port B transmits data,
Port C receives data.) FIFO data can be read out of ports B and written into
port C using either 18-bit or 9-bit formats.
Reset (
RST)initializesthereadandwritepointerstothefirstlocationofthe
memory array and selects one of four possible default flag offset settings: 4, 8,
12 or 16.
Each FIFO has flags to indicate empty and full conditions and two program-
mable flags (Almost-Full and Almost-Empty) to indicate when a selected
