3 Description

The TMP1827 is a high-accuracy, 1-Wire compatible

digital output temperature sensor with integrated 2Kb

EEPROM, SHA-256-HMAC authentication scheme

and a wide operating temperature range from –55°C

to +150°C. The TMP1827 provides a high accuracy

of ±0.1°C (typical)/±0.2°C (maximum) across the

temperature range of +10°C to +45°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 1-

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.
