723644L12PF8 General Description

The 723644 is a CMOS bidirectional synchronous (clocked) FIFO. Two independent 1K x 36 dual-port SRAM FIFOs on board each chip buffer data in opposite directions. 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 synchronous control.

Key Features

Clock frequencies up to 83 MHz (8 ns access time)
Two independent clocked FIFOs buffering data in opposite directions
Programmable Almost-Empty and Almost-Full flags
Serial or parallel programming of partial flags
Port B bus sizing of 36-bits (long word), 18-bits (word) and 9-bits (byte)
Big- or Little-Endian format for word and byte bus sizes
Mailbox bypass registers for each FIFO
Free-running CLKA and CLKB may be asynchronous or coincident
Auto power down minimizes power dissipation
Available 128-pin TQFP package
Industrial temperature range (–40C to +85C) is available
