FEATURES

• Serial or parallel programming of partial flags

• Big- or Little-Endian format for word and byte bus sizes

• Loopback mode on Port A

• Retransmit Capability

• Master Reset clears data and configures FIFO, Partial Reset

clears data but retains configuration settings

• Memory storage capacity:

• Clock frequencies up to 83 MHz (8ns access time)

• Two independent FIFOs buffer data between one bidirectional

36-bit port and two unidirectional 18-bit ports (Port C receives

and Port B transmits)

• 18-bit (word) and 9-bit (byte) bus sizing of 18 bits (word) on

Ports B and C

• Select IDT Standard timing (using EFA , EFB , FFA , and FFC flag

functions) or First Word Fall Through Timing (using ORA, ORB,

IRA, and IRC flag functions)

• Mailbox bypass registers for each FIFO

• Free-running CLKA, CLKB and CLKC may be asynchronous or

coincident (simultaneous reading and writing of data on a single

clock edge is permitted)

• Auto power down minimizes power dissipation

• Available in a space-saving 128-pin Thin Quad Flatpack (TQFP)

• Pin compatible to the lower density parts, IDT723626/3636/3646

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

• Programmable Almost-Empty and Almost-Full flags; each has
