The DS1615 is a digital thermometer produced by DALSEMI, which can measure temperatures from -40°C to +85°C with an accuracy of ±2°C. The product has real-time clock/calendar, temperature recording and alarm functions, and can read and write data via serial interface.
The DS1615 is an integrated temperature recorder that combines a real‑time clock, data‑logging, and histogram capabilities. It measures temperatures from -40 °C to +85 °C in 0.5 °C steps with ±2 °C accuracy and can store up to 2,048 temperature samples.
The device offers two serial interfaces (synchronous 3‑wire and asynchronous UART), programmable high/low alarm thresholds, and a 63‑bin histogram with 2 °C resolution. Memory is organized into 32‑byte pages covering RTC, user NV RAM, alarm data, histogram, and datalog storage.
