Its standout feature is the 2.7V to 30V supply range, which lets it run directly off an unregulated industrial 24V rail or a multi-cell Li-ion battery without a front-end regulator. The ZACwire™ one-wire interface handles both programming and digital readback on a single pin, saving an MCU GPIO and simplifying galvanic isolation. That 2.7V minimum means the part stays alive through a battery's end-of-life voltage, and the 30V ceiling covers a 24V nominal rail with margin for transients. You can drop the dedicated LDO or DC-DC that a 3.3V-only conditioner would need — one less inductor, one less ceramic cap. The wide supply also simplifies reverse-polarity protection: a single series diode still leaves enough headroom for the conditioner to operate. No exposed pad means no via-stitch thermal management, but the part's quiescent draw is low enough that dissipation isn't a concern at room temperature. ## ZACwire one-wire: firmware and layout notes The ZACwire interface is a single-wire bidirectional protocol — the host MCU sends commands and receives data on the same line. The firmware engineer needs to budget for a bit-banged UART or a dedicated timer capture/compare channel; there's no hardware ZACwire peripheral on most MCUs. On the PCB, keep the trace short and avoid routing it near a switching node to preserve signal integrity during programming.","metaTitle":"ZSC31015EAG1-R RBicLite™ Sensor Signal Conditioner, 2.7V-30V","metaDescription":"ZSC31015EAG1-R RBicLite™ resistive sensor signal conditioner from Renesas. 2.7V to 30V supply range, ZACwire one-wire interface, 8-SOIC.","metaKeywords":null},"attributes":{"series":"RBicLite™","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"RBicLite™","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"ZACwire™ One-Wire Interface","Applications":"Sensor Signal Conditioner - Resistive","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 30V","Supplier Device Package":"8-SOIC"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.08","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.08000","currency":"USD"},{"qty":10,"price":"$5.49400","currency":"USD"},{"qty":25,"price":"$5.23840","currency":"USD"},{"qty":100,"price":"$4.54840","currency":"USD"},{"qty":250,"price":"$4.34400","currency":"USD"},{"qty":500,"price":"$3.96072","currency":"USD"},{"qty":1000,"price":"$3.44966","currency":"USD"},{"qty":2500,"price":"$3.32189","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a79ebe938d7ba2a29b1da1cbe0d007f1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is ZSC31015EAG1-R used for?","answer":"It is a resistive sensor signal conditioner — it linearizes, amplifies, and digitizes the output of resistive bridge sensors such as pressure transducers, load cells, and strain gauges.
