DESCRIPTION:
The IDT723624/723634/723644 is a monolithic, high-speed, low-
power, CMOS bidirectional synchronous (clocked) FIFO memory which
supports clock frequencies up to 83 MHz and has read access times as fast as
8 ns. Two independent 256/512/1,024 x 36 dual-port SRAM FIFOs on board
each chip buffer data in opposite directions. FIFO data on Port B can be input
and output in 36-bit, 18-bit, or 9-bit formats with a choice of Big- or Little-Endian
configurations.
These devices are a synchronous (clocked) FIFO, meaning each port
employs a synchronous interface. All data transfers through a port are gated
to the LOW-to-HIGH transition of a port clock by enable signals. The clocks for
each port are independent of one another and can be asynchronous or
coincident. The enables for each port are arranged to provide a simple
bidirectional interface between microprocessors and/or buses with syn-
chronous control.
