1 Overview
The TMP104 is a digital output temperature sensor in a four-ball, wafer chip-scale package (WCSP). The
TMP104 is capable of reading temperatures to a resolution of 1 ° C, and is specified for operation over a
temperature range of – 40 ° C to +125 ° C.
The TMP104 features a one-wire UART-style interface that supports daisy-chain configurations. In
addition, the interface supports multiple device access (MDA) commands that allow the master to
communicate with multiple devices on the bus simultaneously, eliminating the need to send individual
commands to each TMP104 on the bus. Up to 16 TMP104s can be tied together in parallel and easily
read by the host. This device is especially ideal for space-constrained, power-sensitive applications with
multiple temperature measurement zones that must be monitored.
The TMP104EVM is a platform for evaluating the performance of the TMP104 under various signal,
reference, and supply conditions. This document gives a general overview of the TMP104EVM and
provides a general description of the features and functions to be considered while using this evaluation
module.
