DESCRIPTION:

The IDT723614 is a monolithic, high-speed, low-power BiCMOS bidirectional clocked FIFO memory. It supports clock frequencies up to 67MHz and has read access times as fast as 10ns. Two independent 64 x 36 dual-port SRAM FIFOs on board the chip buffer data in opposite directions.

FEATURES:

? Free-running CLKA and CLKB can be asynchronous or

coincident (simultaneous reading and writing of data on a

single clock edge is permitted)

? Two independent clocked FIFOs (64 x 36 storage

capacity each) buffering data in opposite directions

? Mailbox bypass Register for each FIFO

? 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

? EFA, FFA, AEA, and AFA flags synchronized by CLKA

? EFB, FFB, AEB, and AFB flags synchronized by CLKB

? Passive parity checking on each port

? Parity generation can be selected for each port

? Low-power advanced BiCMOS technology

? Supports clock frequencies up to 67 MHz

? Fast access times of 10 ns

? Available in 132-pin plastic quad flat package (PQF) or

space-saving 120-pin thin quad flat package (TQFP)

? Industrial temperature range (-40°C to +85°C) is

available, tested to military electrical specifications
