ASMTargeting Smart Meter applications popular in Europe, Accent’s ASM221 kit supports popular narrowband OFDM PLC standards including PRIME, G3, and evolving P1901.2. The kit’s turnkey software offering includes respective PHY, MAC, and convergence layer software libraries, with a similar flexible approach to the ASM211 taken for the PLC PHY, SUNFX-PLC. Only a small portion of the 110 DMIPS from the ASM221 ARM Cortex-M3 is used for SUNFX-PLC processing, leaving the remainder to serve as a meter’s central application processor. The ASM221 kit also integrates Accent’s AEMET with similar energy measurement support as the ASM201.
