To provide complete advanced smart meter solutions, the ASMgrid2 system-on-chip architecture encompasses a broad range of technologies including high-precision analog-front-ends, RF transceivers, non-volatile memories, and processing capabilities needed to run required protocol stacks and vendor application software. Each one of the three devices in the ASMgrid2 product family contains an ARM processor for unmatched performance, code density, and development capability. In addition to other processing, the ARM processors are also used in combination with hardware acceleration for Accent’s SUNFXTM modems, providing adaptable solutions for still evolving utility communication standards.

The ASM201, ASM211 and ASM221 feature an ARM ARM926EJ-S, an ARM Cortex-M0 and an ARM Cortex-M3 processor, respectively, running at 192, 88 and 88MHz. They integrate from 32 to 512MB of flash and 32 to 64KB of SRAM.
