SM2400
1. Introduction
The SM2400 is the ultimate Narrow-band Power Line Communication (N-PLC) modem that combines cost-
effective design optimized for PLC applications with high level of programmability to address multitude of
communications schemes and evolving standards. Extremely flexible the SM2400 system-on-chip (SoC) features
a dual core architecture for dedicated PHY signal processing and MAC layer functionality to guarantee superior
communication performance while maintaining very high levels of flexibility and programmability for OFDM based
and other open standards and fully customized implementations. It contains a high-speed 256-bit AES-CCM*
engine to ensure standard compliance and secure communication, and all the necessary mixed signal
components, such as A/D, D/A, OpAmp's, PGA to yield a cost-effective N-PLC system design for any IoT
application.
The SM2400 is a highly programmable OFDM based N-PLC modem combining PHY and MAC with mixed signal
components for optimal system cost and performance. The SM2400 combines the benefits of programmable
architecture with power and cost efficiency by utilizing a DSP core configured specifically for N-PLC modulations
and a dedicated 32-bit core that runs protocols. With its high level of programmability, the SM2400 addresses
multitude of communications schemes and can accommodate application specific communication schemes and
evolving standards.
The SM2400 comes with a set of firmware options implementing IEEE 1901.2 compliant PHY and MAC layers, a
6LoWPAN data link layer as well as PRIME, G3-PLC and other special modes tailored for Industrial IoT
applications.
Proprietary and patented modes (XXR and XR) enable robust communication in harsh conditions for applications
where standards compliance is not required. The SM2400 can achieve data rates of up to 500 kbps over 500 kHz
frequency band.
The SM2400 enables secure communication featuring a 256-bit AES encryption core with CCM* mode support.
Integrated analog front end featuring ADC, DAC, gain control and two OpAmp's allows for a very efficient system
design with a low cost BOM.
The SM2400 executes its firmware from internal memory. The code is loaded at the boot time. The SM2400 can
boot either from an external SPI flash or from a host MCU, if such is present in the system, via UART or SPI, with
the host MCU being the master.
The SM2400 offers the following benefits:
• Single-chip integrating Physical Layer (PHY) and Media Access Controller (MAC)
• Multitude of operating modes addressing all common OFDM-based standards including full compliance with:
IEEE 1901.2, G3-PLC, PRIME
• Extremely robust proprietary modes of communication optimized for noisy power line environment
• High flexibility to address standard evolution, new standards and special proprietary modes
• Cost optimized system solution with integrated A/D, D/A, two OpAmp's, and PGA
• Low power consumption
