Product details

Overview

SI7053-EVB from Silicon Labs is an evaluation board designed to demonstrate the SI7053 high-accuracy digital temperature sensor IC in a 3 mm × 3 mm DFN package, featuring ±0.1 °C accuracy from 0 °C to 70 °C, 14-bit resolution, and I²C interface with user-configurable resolution and heater control. It enables rapid prototyping of precision thermal monitoring in battery-powered IoT endpoints.

For engineers reviewing the SI7053-EVB datasheet, SI7053-EVB pinout, SI7053-EVB application, or SI7053-EVB equivalent, this board provides direct access to calibrated temperature data, on-board voltage regulation, test points for VDD/SCL/SDA/HEATER/GND, and compatibility with Simplicity Studio 6 for real-time sensor configuration and logging.

Technical Context

The SI7053-EVB implements the SI7053 sensor IC in a fixed-voltage (3.3 V) configuration with integrated pull-up resistors on I²C lines, onboard 10 kΩ heater resistor for dew-point testing, and gold-plated edge connectors for breadboard or header-based interfacing. It supports standard-mode (100 kHz) and fast-mode (400 kHz) I²C communication without external level shifting.

Designed for plug-and-play validation, the board includes no microcontroller - it relies on host MCU or PC-based USB-I²C adapter (e.g., CP2112) for command execution. All sensor registers - including resolution, heater enable, and serial number - are accessible via standard I²C read/write sequences defined in the SI7053 datasheet Rev. 1.3.

FAQ

What is the primary function of the SI7053-EVB?

The SI7053-EVB is an evaluation board that hosts the SI7053 high-accuracy digital temperature sensor IC. Its purpose is to simplify characterization, firmware integration, and system-level thermal validation. The SI7053-EVB provides direct I²C access to calibrated temperature readings, on-board heater control, and standardized test points - eliminating custom PCB design during early development of temperature-sensitive applications.

Does the SI7053-EVB include a humidity sensor?

No. Although the SI7053 die integrates both temperature and humidity sensing elements, the SI7053-EVB is configured exclusively for temperature measurement. The humidity functionality is disabled in hardware per the board's design intent and documentation. Users seeking humidity capability must select the SI7021-EVB or SI7034-EVB instead of the SI7053-EVB.

Can the SI7053-EVB operate from a 5 V supply?

No. The SI7053-EVB is designed for 3.3 V operation only. Its onboard regulator and signal conditioning circuitry are not rated for 5 V input. Applying 5 V may damage the SI7053-EVB or cause unreliable I²C communication. For 5 V host systems, level-shifting circuitry or a 3.3 V auxiliary rail is required to safely interface with the SI7053-EVB.

How do I configure resolution and heater control on the SI7053-EVB?

Resolution and heater control are managed via I²C register writes to the SI7053 sensor IC on the SI7053-EVB. Standard commands - such as writing 0x01 to register 0xE0 to enable the heater - follow the protocol defined in the SI7053 datasheet. Simplicity Studio 6 provides built-in examples and GUI tools to send these commands without custom code.

Is the SI7053-EVB RoHS compliant and lead-free?

Yes. The SI7053-EVB complies with RoHS Directive 2011/65/EU and is manufactured using lead-free solder and halogen-free laminates. This compliance is confirmed in Silicon Labs' official product change notices (PCNs) and packaging documentation for the SI7053-EVB, ensuring suitability for commercial and medical electronics markets with strict environmental requirements.
