It integrates the 71M6541 energy-metering system on chip (SoC) that provides 0.1% accuracy across a wide current range of 2000:1. The G3-PLC chipset, which includes the MAX2991 and MAX2992, features adaptive tone mapping, notching, and robust mode to ensure communication in the noisiest of conditions. The MAXQ1050 secure microcontroller supports advanced and scalable encryption standards and protects against physical attacks from hackers. The demands of new applications, such as EV reverse flow control, also mean that there are evolving requirements in smart grid implementation. The powerful components in the Newport smart meter reference platform provide the flexibility to handle uncertainties such as security algorithms, different communication protocols, and the need for field-upgradable meters. By using this smart-meter platform, designers can evaluate the MAX2991/MAX2992 G3-PLC compliant chipset, the 71M6541 metering SoC, and the MAXQ1050 secure microcontroller for their next-generation smart meters.

The Newport platform includes two communications sockets, allowing for independent neighborhood area network (NAN) and home are network (HAN) interfaces. Maxim’s G3-PLC chipset (MAX2991/MAX2992) is installed in one socket to provide communication for either meter to concentrator (route A), meter to in-home display and home gateway (route B), or both. The chipset complies with the emerging IEEE(R) P1901.2 standard for OFDM-based communication over power lines and offers guaranteed interoperability. The MAX2992 also includes an on-chip CCM authentication coprocessor with AES-128 encryption/decryption.
