The TMP1827 is a high-accuracy, single-wire compatible digital output temperature sensor with integrated 2-kbit EEPROM and SHA-256-HMAC authentication scheme with a wide operating temperature range from –55°C to +150°C. The TMP1827 provides a high accuracy of ±0.1°C (typical)/±0.3°C (maximum) across the temperature range of –20°C to +85°C. Each device comes with a factory programmed 64-bit unique identification number for addressing and NIST traceability. The TMP1827 supports both standard speed for legacy application and overdrive mode with 90-kbps data rate for low latency communication across a wide voltage range of 1.7 V to 5.5 V.

In the simplest mode of operation, the TMP1827 single-wire interface, with an integrated 8-kV IEC-61000-4-2 ESD protection on the data pin, requires only a single connection and a ground return in bus powered mode, which simplifies and reduces cost by reducing the number of wires and external protection components. Additionally, there is the VDD power pin also available for applications that may want to have a dedicated power supply.
