FEATURES
DESCRIPTION
DEVICES INCORPORATED
The
LPR520
is functionally compat-
ible with the L29C520 but have 16-bit
inputs and outputs. The LPR520 is
implemented in low power CMOS.
The LPR520 contains four registers
which can be configured as two
independent, 2-level pipelines or as
one 4-level pipeline.
The Instruction pins, I
1-0
, control the
loading of the registers. The registers
may be configured as a four-stage
delay line, with data loaded into R1
and shifted sequentially through R2,
R3, and R4. Also, data may be loaded
from the inputs into either R1 or R3
with only R2 or R4 shifting. Finally,
I
1-0
may be set to prevent any register
from changing.
The S
1-0
select lines control a 4-to-1
multiplexer which routes the contents
of any of the registers to the Y output
pins. The independence of the I and S
controls allows simultaneous write
and read operations on different
registers.
