IDT72V3626/72V3636/72V3646 CMOS 3.3V TRIPLE BUS SyncFIFOTM
WITH BUS-MATCHING 256 x 36 x 2, 512 x 36 x 2, 1,024 x 36 x 2
COMMERCIAL TEMPERATURE RANGE
DESCRIPTION:
The IDT72V3626/72V3636/72V3646 are pin and functionally compatible
versions of the IDT723626/723636/723646, designed to run off a 3.3V supply
for exceptionally low-power consumption. These devices are a monolithic,
high-speed, low-power, CMOS Triple Bus synchronous (clocked) FIFO
memory which supports clock frequencies up to 100 MHz and has read access
times as fast as 6.5ns. Two independent 256/512/1,024 x 36 dual-port SRAM
FIFOs on board each chip buffer data between a bidirectional 36-bit bus (Port
A) and two unidirectional 18-bit buses (Port B transmits data, Port C receives
data.) FIFO data can be read out of Port B and written into Port C using either
18-bit or 9-bit formats with a choice of Big- or Little-Endian configurations.
These devices are a synchronous (clocked) FIFO, meaning each port
employs a synchronous interface. All data transfers through a port are gated
to the LOW-to-HIGH transition of a port clock by enable signals. The clocks for
