IDT723611

CMOS SyncFIFO

64 x 36

Integrated Device Technology, Inc.

• Fast access times of 10ns

FEATURES:

• Available in 132-pin Plastic Quad Flatpack (PQF) or

space-saving 120-pin Thin Quad Flatpack (PF)

• Low-power advanced CMOS technology

• Free-running CLKA and CLKB may be asynchronous or

coincident (permits simultaneous reading and writing of

data on a single clock edge)

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

able, tested to military elecrical specifications

• 64 x 36 storage capacity

• Synchronous data buffering from Port A to Port B

• Mailbox bypass register in each direction

• Programmable Almost-Full (AF) and Almost-Empty (AE)

flags

• Microprocessor Interface Control Logic

• Full Flag (FF) and Almost-Full (AF) flags synchronized by

CLKA

• Empty Flag (EF) and Almost-Empty (AE) flags synchro-

nized by CLKB

• Passive parity checking on each Port

• Parity Generation can be selected for each Port

• Supports clock frequencies up to 67MHz

DESCRIPTION:

The IDT723611 is a monolithic, high-speed, low-power,

CMOS Synchronous (clocked) FIFO memory which supports

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

fastas10ns.The64x36dual-portFIFObuffersdatafromPort

A to Port B. The FIFO has flags to indicate empty and full

conditions,andtwoprogrammableflags,Almost-Full(AF)and

Almost-Empty (AE), to indicate when a selected number of

words is stored in memory. Communication between each

port can take place through two 36-bit mailbox registers. Each
