Basic Description for PCL Series
This document outlines the major functions of the PCL series pulse control LSIs, which are not part of the PCD
series
I. Outline
The PCD/PCL series pulse control LSIs manufactured by NPM now have a varied lineup. These products (17
models) can be divided into the following three groups, according to their command functions and registers.
･
PCL-240 family
PCD4500/4511/4521/4541
PCL-240AK/240MK/240AS/240MS
･
PCL50oo family (PCL50oo series)
PCL3013/5014
PCL5022/5023
･
PCL60oo family (PCL61oo series/60oo series)
PCL6113/6123/6143
PCL6025/6045B
1. PCL-240 family
In this family, each command is allocated a specific bit.
Basically, this is a simple family that has only four modes: start mode, control mode, register select mode, and
an output mode (8 bits are used for each mode). Since the PCL-240 series has a larger number of functions
than the PCD series, some commands for additional functions are accessed through registers.
2. PCL50oo series
The PCL55oo series has many more functions than the PCL-240 family, with lots of commands and registers.
The method for writing and reading this series is different from the PCL-240 family.
The PCL5022/5023 are LSIs for controlling two axes. The specifications for these LSIs when working on one
axis are not as broad as the PCL5014, which can be used for linear interpolation. (For details about linear
interpolation, see the user's manual for each model, or see page 17 in this document.)
3. PCL61oo series / 60oo series
The PCL60oo series has still more functions than the PCL50oo series, such as lots of counters, comparators,
and an arc interpolation function (see page 16). The bits for commands, registers, and status conditions have
been named for easy reference. This series contains the best models we offer.
PCL61oo series has fewer functions than the PCL60oo series, and they cost much less as well. Even though
the functions are limited, the basic high level functions are still present, such as servomotor control and linear
interpolation. The power supply requirement is just 3.3 V. They offer the highest output frequency offered by
the NPM pulse control LSIs, and they can control high-resolution linear motors.

When our models are classified by compatibility with software programs, there are 6 types, as shown
below:
(1) PCD4500/4511/4521/4541
(2) PCL-240AK/240MK/240AS/240MS
(3) PCL3013/5014
(4) PCL5022/5023
(5) PCL6113/6123/6143
(6) PCL6025/6045B
