IDT72V3643

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

FEATURES:

• Reset clears data and configures FIFO, Partial Reset clears data

but retains configuration settings

• Mailbox bypass registers for each FIFO

• Free-running CLKA and CLKB may be asynchronous or

coincident (simultaneous reading and writing of data on a single

clock edge is permitted)

• Memory storage capacity:

IDT72V3623–256 x 36

IDT72V3633–512 x 36

IDT72V3643–1,024 x 36

• Clock frequencies up to 100 MHz (6.5 ns access time)

• Clocked FIFO buffering data from Port A to Port B

• IDT Standard timing (using EF and FF) or First Word Fall

Through Timing (using OR and IR flag functions)

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

three default offsets (8, 16 and 64)

• Serial or parallel programming of partial flags

• Port B bus sizing of 36 bits (long word), 18 bits (word) and 9 bits

(byte)

• Easily expandable in width and depth

• Auto power down minimizes power dissipation

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

• Pin and functionally compatible versions of the 5V operating

IDT723623/723633/723643

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