LPR520/521  
4 x 16-bit Multilevel Pipeline Register  
DEVICES INCORPORATED  
FEATURES  
DESCRIPTION  
The LPR520 and LPR521 are functionally The S1-0 select lines control a 4-to-1  
Four 16-bit Registers  
compatible with the IDT29FCT520/  
IDT29FCT521 and AMD Am29520/  
Am29521 but have 16-bit inputs and  
outputs. They are implemented in low  
power CMOS.  
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.  
Implements Double 2-Stage Pipe-  
line or Single 4-Stage Pipeline  
Register  
Hold, Shift, and Load Instructions  
Separate Data In and Data Out Pins  
The LPR520 and LPR521 contain four  
registers which can be configured as  
two independent, 2-level pipelines or  
as one 4-level pipeline.

Three-State Outputs  
DESC SMD No. 5962-89716  
The Instruction pins, I1-0, control the  
loading of the registers. For either  
device, the registers may be config-  
ured as a four-stage delay line, with  
data loaded into R1 and shifted  
sequentially through R2, R3, and R4.  
Also, for the LPR520, data may be  
loaded from the inputs into either R1  
or R3 with only R2 or R4 shifting. The  
LPR521 differs from the LPR520 in  
that R2 and R4 remain unchanged  
during this type of data load, as  
shown in Tables 1 and 2. Finally, I1-0  
may be set to prevent any register  
from changing.
