Microchip Technology Inc., announced that it partnered with Kalki Communication Technologies Ltd. (Kalkitech) to provide a Device Language Message Specification (DLMS) protocol stack that is optimized for 16-bit PIC® microcontrollers (MCUs). The DLMS protocol has become the worldwide standard of choice among smart meter designers for interoperability among metering systems, including most energy types (electricity, gas, heat and water), multiple applications (residential, transmission and distribution), and numerous communication media (RS232, RS485, PSTN, GSM, GPRS, IPv4, PPP and PLC); as well as secure data access, via AES 128 encryption.

Microchip’s 16-bit PIC microcontrollers

This software stack has been tested and verified by the DLMS User Association, and is customized to operate on all of Microchip’s 16-bit PIC microcontrollers and dsPIC® Digital Signal Controllers (DSCs), making the DLMS certification process faster and easier. Additionally, the stack has been developed to ensure seamless integration with Microchip’s communication protocol stacks, including TCP/IP, ZigBee® and PLC, covering a broad spectrum of smart energy applications. Furthermore, this DLMS stack has been optimized to fit in a small memory footprint, enabling the use of the smallest, most cost-effective MCUs possible. For European applications, the stack provides support for the required IEC 62056-21 Mode E implementation.

“The addition of this DLMS library to Microchip’s smart energy offerings reinforces our continued focus on providing cost-effective and comprehensive solutions to our customers,” said Mitch Obolsky, vice president of Microchip’s Advanced Microcontroller Architecture Division. “Now, customers can leverage Microchip’s vast portfolio of communication protocol solutions, such as TCP/IP, ZigBee and PLC, to create a fully integrated smart energy system.”
