Microchip Kalkitech DLMS protocol stack

Microchip has partnered with Kalki Communication Technologies (Kalkitech) to provide a device language message specification (DLMS) protocol stack that is optimised for 16-bit PIC microcontrollers.

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.

The software stack has been tested and verified by the DLMS User Association, and is customised to operate on all Microchip’s 16-bit PIC microcontrollers and dsPIC digital signal controllers, making the 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.

The stack has been optimised to fit in a small memory footprint, enabling the use of the smallest MCU possible.
