DESCRIPTION:
The IDT72V255LA/72V265LA are functionally compatible versions of the
IDT72255/72265 designed to run off a 3.3V supply for very low power
consumption. The IDT72V255LA/72V265LA are exceptionally deep, high
speed, CMOS First-In-First-Out (FIFO) memories with clocked read and
write controls. These FIFOs offer numerous improvements over previous
SuperSync FIFOs, including the following:
The limitation of the frequency of one clock input with respect to the other
has been removed. The Frequency Select pin (FS) has been removed,
thus it is no longer necessary to select which of the two clock inputs, RCLK
or WCLK, is running at the higher frequency.
