FEATURES:
Memory storage capacity:
IDT72V3624–256 x 36 x 2
IDT72V3634–512 x 36 x 2
IDT72V3644–1,024 x 36 x 2
Clock frequencies up to 100 MHz (6.5ns access time)
Two independent clocked FIFOs buffering data in opposite
directions
Select IDT Standard timing (using EFA, EFB, FFA, and FFB
flags functions) or First Word Fall Through Timing (using ORA,
ORB, IRA, and IRB 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)
Big- or Little-Endian format for word and byte bus sizes
Master 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 coinci-
dent (simultaneous reading and writing of data on a single clock
edge is permitted)
Auto power down minimizes power dissipation
Available in space saving 128-pin Thin Quad Flatpack (TQFP)
Pin and functionally compatible version of the 5V operating
IDT723624/723634/723644
Industrial temperature range (–40
°°°°°C to +85°°°°°C) is available
Green parts available, see ordering information
