description
A FIFO memory is a storage device that allows
data to be written into and read from its array at
independent data rates. The SN74ACT7806 is a
256-word by 18-bit FIFO for high speed and fast
access times. It processes data at rates up to
50 MHz and access times of 15 ns in a bit-parallel
format.
Data is written into memory on a low-to-high
transition at the load clock (LDCK) input and is
read out on a low-to-high transition at the unload
clock (UNCK) input. The memory is full when the
number of words clocked in exceeds the number
of words clocked out by 256. When the memory is
full, LDCK signals have no effect on the data
residing in memory. When the memory is empty,
UNCK signals have no effect.
Status of the FIFO memory is monitored by the full (FULL), empty (EMPTY), half-full (HF), and
almost-full/almost-empty (AF/AE) flags. The FULL output is low when the memory is full and high when the
memory is not full. The EMPTY output is low when the memory is empty and high when it is not empty. The HF
output is high when the FIFO contains 128 or more words. The AF/AE status flag is a programmable flag. The
first one or two low-to-high transitions of LDCK after reset are used to program the almost-empty offset value
(X) and the almost-full offset value (Y) if program enable (PEN) is low. The AF/AE flag is high when the FIFO
contains X or fewer words or (256 – Y) or more words. The AF/AE flag is low when the FIFO contains between
(X + 1) and (255 – Y) words.
