Smart metering platform available on a 32-bit MCU

23 November 2022 DSP, Micros & Memory

To meet the growing demand for a feature-rich yet simple design solution for developing smart meters, Microchip has announced the PIC32CXMT family of 32-bit microprocessors with a new MPL460 power line communication (PLC) modem. The new suite of MCU devices is a next-generation smart metering platform targeting industrial IoT, commercial and industrial metering applications. The platform boasts increased performance with up to 200 MHz operation and broad scalability with up to 560 kB of memory (SRAM).

The PIC32CXMT family is offered in three variants based on a single Arm Cortex-M4F core, a dual Arm Cortex-M4 core and a system-on-chip (SoC) device. The MPL460 PLC modem integrates the line driver for signal amplification, which reduces the bill of materials and provides a signal injection efficiency above 40%. The PLC modem helps to increase efficiency and reliability based on power delivered to the load and power taken from the supply, resulting in an overall reduction in consumption from the source during transmission.

The platform provides several transceiver solutions, including a radio/PHY, a PLC/PHY or the option to select a PLC+RF hybrid solution. It also supports standards for wired and wireless communications, such as G3-PLC and PRIME.
