High Performance Narrow Band Power Line Communication Modem IC

R9A06G037 is a high performance NB-PLC (Narrow Band Power Line Communication) modem IC.

R9A06G037 integrates a high performance DSP core and a MCU core (Arm® Cortex®-M3).

The DSP core mainly handles PLC PHY layer protocol and the ARM core handles the upper layer protocol. R9A06G037 can support a variety of PLC protocols such as G3-PLC (CENELEC, ARIB and FCC), PRIME and many others.
