BiCMOS SyncBiFIFO

64 x 36 x 2

Integrated Device Technology, Inc.

• Low-power advanced BiCMOS technology

• Supports clock frequencies up to 67 MHz

• Fast access times of 10ns

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

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

• Industrial temperature range (-40oC to +85oC) is avail-

able, tested to military electrical specifications

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

• 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

DESCRIPTION:

The IDT723612 is a monolithic high-speed, low-power

BiCMOS bi-directional clocked FIFO memory. It supports

clock frequencies up to 67 MHz and has read access times as

• Parity generation can be selected for each port
