Microchip, with the DLMS User Alliance Certification Stack for PIC® MCUs, smart meters worldwide
Through a DLMS stack custom-configured for interoperability-supported MCUs
Implemented interoperability across a wide range of energy types and communication protocols for the first time in the industry

Microchip Technology (Country Manager for Korea: Byung-Don Han), a global leader in microcontroller, analog, and flash IP solutions, announced today that it is providing a Device Language Message Specification (DLMS) protocol stack optimized for 16-bit PIC® microcontrollers (MCUs) in collaboration with Kalki Communication Technologies. The DLMS protocol is establishing itself as a global standard preferred by smart meter designers for secure data access via AES 128 encryption, as well as interoperability between metering systems—such as most energy types (electricity, gas, heating, and water/sewerage), various applications (residential, transmission, distribution), and communication media (RS232, RS485, PSTN, GSM, GPRS, IPv4, PPP, PLC).

This software stack has not only been tested and verified by the DLMS User Alliance but is also custom-configured to operate on all of Microchip's 16-bit PIC microcontrollers and dsPIC® digital signal controllers (DSCs), enabling the DLMS certification process to be completed more easily and quickly. Additionally, this stack is designed to integrate tightly with communication protocol stacks such as TCP/IP, ZigBee®, and PLC, making it applicable to a wide range of smart energy applications. In addition, it is optimized for a small memory footprint, allowing the use of the industry's smallest and most economical MCUs. For European applications, this stack supports IEC 62056-21 Mode E, which is required to implement the application.

"The addition of this DLMS library to Microchip's smart energy products further strengthens Microchip's efforts to provide cost-effective and comprehensive solutions," said Mitch Obolsky, Vice President of Microchip's Advanced Microcontroller Architecture business unit. "Customers can now build fully integrated smart energy systems by leveraging Microchip's vast portfolio of communication protocol solutions, such as TCP/IP, Zigbee, and PLC."
