Smart meter chip adds multi-standard OFDM powerline communications for M2M
The ASM220 uses the company’s field-proven SUNFX-PLC silicon to support multiple leading standards such as G3-PLC, PRIME, ITU G.990x and IEEE P1901.2. The ASM220 targets the rapidly growing powerline communications (PLC) Smart Meter market as well as emerging M2M applications such as distribution automation, solar, building automation, and street lighting.
The device tailors existing ASMgrid2 solutions primarily towards the communication as well as processing needs for many M2M applications. SUNFX-PLC is already incorporated in Accent’s ASM221 and which also recently completed G3-PLC interoperability testing, implements a hybrid hardware/software PLC modem as well as analog front end. An ARM Cortex-M3 serves as the processor backbone for the SUNFX-PLC modem with performance intensive blocks implemented in hardware. The ASM220 also implements a scalable SDRAM memory system with an ARM Cortex-M3 with 110+ DMIPS of performance for both application and communication processing, with 256KB/48KB of embedded Flash/SRAM and a 2 MB package option. The ASM220 fully leverages the ASMgrid2 solution platform, which includes communications stacks, development boards, and reference designs.
The system is compliant with CENELEC, FCC, and ARIB bands of operation from 10 kHz to 490 kHz and includes an integrated PLC AFE for low system bill-of-materials.
“The ASM220 is a natural next step to the ground-breaking path set by ASMgrid2’s set of products of combining high feature integration and product innovation”, said Federico Arcelli, CEO of Accent. “The new offering retains leading-edge, field-proven PLC capability and performance scalability to address a wider range of applications than all other solutions in the market.”
