COMMERCIAL TEMPERATURE RANGE
FEATURES:
64 x 36 storage capacity FIFO buffering data from Port A to Port B
Supports clock frequencies up to 67MHz
Fast access times of 10ns
Free-running CLKA and CLKB may be asynchronous or
coincident (permits simultaneous reading and writing of data on
a single clock edge)
Mailbox bypass registers in each direction
Dynamic Port B bus sizing of 36 bits (long word), 18 bits (word),
and 9 bits (byte)
Selection of Big- or Little-Endian format for word and byte bus
sizes
Three modes of byte-order swapping on Port B
Programmable Almost-Full and Almost-Empty flags
Microprocessor interface control logic
FF , AF flags synchronized by CLKA
EF , AE flags synchronized by CLKB
Passive parity checking on each Port
Parity Generation can be selected for each Port
Available in space saving 120-pin thin quad flat package (TQFP)
Green parts available, see ordering information
DESCRIPTION:
TheIDT72V3613isdesignedtorunoffa3.3Vsupplyforexceptionallylow-
power consumption. This device is a monolithic, high-speed, low-power,
CMOSsynchronous(clocked)FIFOmemorywhichsupportsclockfrequencies
up to 67 MHz and has read-access times as fast as 10 ns. The 64 x 36 dual-
port SRAM FIFO buffers data from port A to port B. The FIFO operates in IDT
Standard mode and has flags to indicate empty and full conditions, and two
programmableflags,Almost-Full(AF)andAlmost-Empty(AE),toindicatewhen
a selected number of words is stored in memory. FIFO data on port B can be
output in 36-bit, 18-bit, and 9-bit formats with a choice of Big- or Little-Endian
configurations.Threemodesofbyte-orderswappingarepossiblewithanybus-
