FEATURES

DESCRIPTION

The LPR520 is functionally compat-

The S1-0 select lines control a 4-to-1

ible with the L29C520 but have 16-bit multiplexer which routes the contents

❑ Four 16-bit Registers

❑ Implements Double 2-Stage

Pipeline or Single 4-Stage Pipeline

inputs and outputs. The LPR520 is

implemented in low power CMOS.

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.

❑ Hold, Shift, and Load Instructions

The LPR520 contains four registers

❑ Separate Data In and Data Out Pins which can be configured as two

independent, 2-level pipelines or as

one 4-level pipeline.

❑ High-Speed, Low Power CMOS

Technology

❑ Three-State Outputs

❑ 44-pin PLCC, J-Lead

The Instruction pins, I1-0, 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,

I1-0 may be set to prevent any register

from changing.
