Pulse Control LSI Special Feature

What is pulse control LSI? An explanation of the features of recommended models for first-time users.

To operate a stepping motor, it goes without saying that some kind of "device or circuit that generates pulse signals" is necessary. In many cases, motor control (motion control) is developed using "CPUs (1-chip microcontrollers)" or "FPGAs," so it would be sufficient to program them to enable "acceleration and deceleration control"!! Of course, that would be enough if it works well, but wait a moment!! Are you aware that there are dedicated devices specifically designed for motor control? They are called "pulse control LSI."

Pulse Control LSI PCD4600 Series

A low-cost version suitable for controlling stepping motors!

We have renewed our conventional model by miniaturizing it and enhancing its functionality. It incorporates the basic functions that are generally considered necessary for open-loop control of stepping motors. Considering the recent CPU landscape, it can be used with either an 8-bit parallel bus or a 4-wire serial bus, broadening the options for compatible CPUs. The 2-axis type measures 10×10 mm, and the 4-axis type measures 14×14 mm, adopting the industry's smallest package in the QFP type. You can develop a multi-axis controller for stepping motors in a "compact," "affordable," and "fast" manner. For more details, please contact us or refer to the catalog.

Pulse Control LSI PCL6000 Series

The highest functionality version of the NPM pulse control LSI!

Linear interpolation/circular interpolation, override of operating speed and target position, triangular drive avoidance function, backlash compensation, vibration suppression during stop, soft limits, direct input of operation switches, various origin return sequences, mechanical input, servo motor interface, and many other features are equipped. These abundant functions allow for the easy construction of complex motion control systems. The PCL6046 enables miniaturization of the board by adopting a BGA package. For more details, please contact us or refer to the catalog.

Pulse Control LSI PCL6100 Series

Low-cost version compatible with servo motors!

The Pulse Control LSI PCL6100 series is equipped with a pre-register (1 stage), up/down counters, and two systems/axes of comparators, linear interpolation functions, and a servo motor interface, making it sufficiently functional for general control. This series is highly recommended for customers who feel that "the PCD4500 series cannot perform the desired operations." It can output a maximum frequency of 15Mpps, making it compatible with high-resolution linear motors. We also offer evaluation boards that can reduce development time. For more details, please contact us or refer to the catalog.

[Application Case of System Analog Technology] LSI for Ultrasonic Diagnostic Equipment

Mass production for Japanese medical device manufacturers! A case where heat generation has been minimized to the extreme through ultra-low power consumption.

In the development of LSI for ultrasound diagnostic devices, we would like to introduce a case where our system analog technology was applied. The challenges were to control approximately 2,000 transducers at a size that could fit into the esophagus and to minimize power consumption to prevent burns. To address this, we arranged the transmitting and receiving circuits connected to the ultrasound transducers (piezo elements) in an array configuration to achieve beamforming. This allowed us to suppress heat generation to an extreme level through ultra-low power consumption. 【Case Overview】 ■ Customer Challenges - Control approximately 2,000 transducers at a size that fits into the esophagus - Minimize power consumption to prevent burns ■ Achievements - Equipped with 1,900 transceivers (transmitting and receiving circuits) in a size of approximately 10mm x 10mm - Incorporated beamforming functionality with a power consumption of 2W *For more details, please refer to the PDF document or feel free to contact us.

Pulse Control LSI PCL6100 Series

Low-cost version compatible with servo motors

It is equipped with a pre-register (one stage), up/down counters and two systems of comparators per axis, linear interpolation function, encoder input, servo motor interface, etc., and has sufficient functionality to handle not only open-loop control but also general closed-loop control. By combining the pre-register and linear interpolation, it can continuously operate along a linear trajectory. The maximum output frequency can reach up to 15Mpps, and the up/down counter has also been upgraded to 32 bits, allowing for high-resolution control of long-stroke linear motors. It is also software-compatible with the previous models PCL3113, PCL6123, and CL6143.

High-speed serial communication LSI G9000 series

Motor I/O data - all consolidated for reduced wiring!

Motionnet® is a high-speed serial communication system proposed by NPM. Based on the uniquely developed "G9000 series" of five types of devices, it is a total wiring reduction system that enables not only input/output control and motor control required in the FA field but also CPU emulation and message communication that can be remotely operated, taking advantage of its high speed. In cyclic communication for input/output control, it consistently transfers 4 bytes of data at a maximum of 15.1μs, during which it can interrupt to communicate up to 256 bytes (maximum) of data such as motor control and LSI control data. The communication time can be calculated using a predetermined formula, ensuring the real-time performance required in the FA field. We confidently recommend it as a solution for core communication systems such as FA control. For more details, please contact us or refer to the catalog.
