With 64K x 8 of RAM and external program memory, this part runs the transceiver firmware and application code from off-chip flash or ROM, keeping the die cost down while the system designer sizes the memory to the job. ## Parametric fit for a control-node BOM Twelve general-purpose I/O lines handle digital sensors, actuators, or a serial interface — enough for a typical LONWORKS node reading a temperature sensor and driving a relay or valve. Industrial temperature grade (-40°C to 85°C) covers rooftop HVAC controllers, plant-floor sensor nodes, and outdoor lighting cabinets — the junction temperature stays inside the safe operating area even with the transceiver active in a sealed enclosure. ## Active production, RoHS compliant The LONWORKS series continues to ship for installed building-automation and industrial networks that require backward-compatible replacements. RoHS compliant per the manufacturer's declaration — no lead, mercury, cadmium, or restricted phthalates in the package or plating.","metaTitle":"Renesas 14235R-500 LONWORKS Smart Transceiver, 48-QFN","metaDescription":"Renesas 14235R-500 LONWORKS Smart Transceiver, Neuron core, 64K x 8 RAM, 12 I/O, -40 to 85°C, 48-QFN.
