3 Description

The TMP1826 is a high-accuracy, 1-Wire compatible

digital output temperature sensor with integrated 2-

kbit EEPROM and a wide operating temperature

range from –55°C to +150°C. The TMP1826 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 TMP1826 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 TMP1826 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.

The 2-kbit EEPROM on the TMP1826 allows the host

to store application data in increments of 64 bits. With

user programmable 256-bit page size write protection

to avoid accidental overwrite, the EEPROM can be

used as non-volatile, read-only memory. The four

digital I/O pins are configurable for general purpose

functions, temperature alert, or provide host to identify

the position of the device on a shared bus.
