PL 3120 Smart Transceiver


The PL 3120 Power Line Smart Transceiver integrates a Neuron processor core with a power line transceiver, making it ideal for appliance, audio/video, lighting, heating/cooling, security, metering, and irrigation applications. A complete system-on-a-chip, the PL 3120 features a highly reliable narrow-band power line transceiver, an 8-bit Neuron processor core for running applications and managing network communications, on-board memory, and an extremely small form factor – all at a price that is compelling for even the most cost-sensitive consumer product applications.
