Atmel Smart Metering Platform
Today’s smart meter architect demands various levels of integration depending on system architecture partitioning,
project timelines, and the level of flexibility needed to address various utility and geographical requirements. The Atmel
platform provides a unique multi-level architecture built around the same multi-core architecture as outlined below.
Various devices integrate the building blocks of the smart meter, namely, metrology sensing (ADC), metrology DSP,
application, communication, and security processing, as well as connectivity to home area and neighborhood area
networks.

Newest Smart Energy Platform Core: SAM4C
At the core of Atmel’s smart energy platform is
the Atmel | SMART SAM4C series of products. The
SAM4C8/16/32 system-on-chip solutions for smart
energy applications are built around two high-
performance 32-bit ARM Cortex
®
-M4 RISC processors.
These devices operate at a maximum speed of
120 MHz and feature up to 2Mbyte of embedded Flash,
304 Kbytes of SRAM, and on-chip cache for each core.
The dual ARM Cortex-M4 architecture allows for
integration of application layer, communications layers,
and metrology functions in a single device. It has options
for integrated software metrology or external hardware
metrology AFE (analog front end) as well as integrated
or external power-line carrier (PLC) physical layer
solution. It’s a modular approach that is sure to meet
various design needs.
