ON Semiconductor has introduced a new power line carrier, or PLC, modem system-on-chip, or SoC, for use in applications such as e-metering, home automation, solar energy and lighting control.
The first device in a new family of PLC modems, the NCN49597 combines a low power 32-bit ARM Cortex M0 processor with a high-precision analog front end. Based on a dual 4800-baud S-FSK (Spread Frequency Shift Keying) channel technology, it has been optimized for power efficiency and performance, while providing reliability to enable operation in the harshest environments, the company said.
According to the company, the NCN49597 is fully compliant with the prevailing IEC61334-5-1 standard and also supports customized implementation of the popular building automation standard while keeping pin-to-pin and function compatibility with its predecessor, the AMIS-49587. The new device adds a host of new features such as field re-programmability, smart synchronization and automatic half baud rate detection that boost robustness of communication and make its implementation and use simpler.
Programmable carrier frequencies in the CENELEC A to D bands and the ability to operate on both AC voltage, at either 50 hertz (Hz) or 60 Hz, and DC voltage enhance the range of applications for which the NCN49597can be utilized. This means a single device is suitable for all types of electrical power grids.10 configurable general purpose inputs / outputs (GPIOs) allow connection to peripherals such as LCDs and metering ICs and alleviate the need for external microcontrollers in applications such as smart plugs. The NCN49597 comes with open source PLC platform code and development environment, the company added.
"This innovative new device builds on ON Semiconductor's 10 years of experience in the field of e-metering and offers a versatile and robust solution for enabling communications in the important and rapidly expanding smart grid market sector," said Ryan Cameron, vice president of Industrial and Timing Products, ON Semiconductor.
"Compatibility with our previous device for this sector plus full compliance with industry standards and the use of proven technology such as the ARM Cortex M0 processor make the utilization of the NCN49597 a risk-free and straightforward process."
