Silicon Labs SI7054-EVB

Overview

SI7054-EVB from Silicon Labs is an evaluation board designed to demonstrate the performance and interface of the SI7054 high-accuracy digital temperature sensor IC in a 3 mm × 3 mm DFN package. It supports I²C communication, delivers ±0.1 °C accuracy from 0 °C to 70 °C, operates from 1.9 V to 3.6 V, and features factory-calibrated output with no user calibration required. The board enables rapid prototyping for battery-powered environmental monitoring systems.

For engineers reviewing the SI7054-EVB datasheet, SI7054-EVB pinout, SI7054-EVB application, or SI7054-EVB equivalent, this page provides verified hardware configuration details, supported host interfaces, thermal test conditions, on-board voltage regulation, and integration guidance for embedded temperature sensing validation.

Technical Context

The SI7054-EVB implements a fixed-voltage 3.3 V LDO regulator to power the SI7054 sensor IC and includes pull-up resistors on SDA/SCL lines for immediate I²C connectivity. It exposes the sensor's dedicated VDD, GND, SDA, and SCL terminals via 0.1-inch spaced headers, enabling direct connection to microcontroller development platforms without level-shifting.

No external components are required for basic operation: the board integrates decoupling capacitors, a reset-capable power supply path, and a calibrated reference trace layout optimized for minimal self-heating error during thermal characterization per JEDEC JESD51-1.
