BUS-MATCHINGANDBYTESWAPPING

64 x 36 x 2

IDT72V3614

• Three modes of byte-order swapping on port B

• Programmable Almost-Full and Almost-Empty flags

• Microprocessor interface control logic

FEATURES:

• Two independent clocked FIFOs (64 x 36 storage capacity each)

buffering data in opposite directions

• 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

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

saving 120-pin thin quad flat package (TQFP)

• Pin and functionally compatible version of the 5V operating

IDT723614

• Supports clock frequencies up to 83 MHz

• Fast access times of 8 ns

• Free-running CLKA and CLKB can be asynchronous or coinci-

dent (simultaneous reading and writing of data on a single

clock edge is permitted)

• 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

• Industrial temperature range (–40°C to +85°C) is available

• Green parts available, see ordering information
