Silicon Labs SI7060-EVB

Overview

SI7060-EVB from Silicon Labs is an evaluation board for the Si7060-B-00-IV(R) I²C temperature sensor IC, enabling rapid validation of its open-drain ALERT output, programmable temperature thresholds (79.8°C operate / 75°C release), ±1°C accuracy over 0–70°C, and 143 μs conversion time in SOT23-5 packaging. It supports autonomous sampling at 5 Hz and ultra-low-power sleep mode (50 nA) for battery-powered thermal monitoring applications.

For engineers reviewing the SI7060-EVB datasheet, SI7060-EVB pinout, SI7060-EVB application, or SI7060-EVB equivalent, this board provides direct access to the Si7060's I²C interface (0x30 address), configurable alert polarity, factory-set hysteresis (2.4°C), and register-level control of sleep timer, one-shot measurement, and threshold storage via OTP registers 0xC6/0xC7.

Technical Context

The SI7060-EVB implements the Si7060-B-00-IV(R) sensor in SOT23-5 package with VDD (1.7–5.5 V), GND, SCL, SDA, and open-drain ALERT pins fully exposed and routed to test points and headers. It enables verification of all three operational modes: Sleep (50 nA), Autonomous Sampling (200 ms interval, 1.5 µA avg), and Active (one-burst conversion).

Board-level design includes pull-up resistors on SDA/SCL lines compatible with 400 kHz Fast-mode I²C, a decoupling capacitor on VDD, and unpopulated footprint for optional external hysteresis resistor. The ALERT output is directly accessible for wire-OR configuration testing with multiple Si7060 devices.

FAQ

What is the primary function of the SI7060-EVB?

The SI7060-EVB is an evaluation board for the Si7060-B-00-IV(R) temperature sensor IC. It provides physical access to all five pins (VDD, GND, SCL, SDA, ALERT), onboard pull-ups, and test points to validate the sensor's I²C communication, autonomous sampling behavior, open-drain alert response, and programmable threshold operation - all critical for integrating the SI7060 into real-world thermal monitoring designs.

Does the SI7060-EVB support multiple Si7060 variants?

No - the SI7060-EVB is configured for the Si7060-B-00-IV(R) variant only, which has a fixed I²C address of 0x30. While other Si7060 variants (0x31–0x33) share identical pinout and functionality, the SI7060-EVB does not include address-select jumpers or DIP switches; it validates the specific behavior and timing of the SI7060-B-00-IV(R) device as shipped.

How is the ALERT output verified on the SI7060-EVB?

The ALERT pin on the SI7060-EVB is routed to a test point and 0.1″ header, allowing direct oscilloscope probing or logic analyzer capture. Its open-drain behavior is confirmed by measuring voltage drop under 3 mA load, and temperature-triggered toggling is validated using a calibrated thermal plate set to cross the factory default 79.8°C operate / 75°C release thresholds - matching register 0xC6/0xC7 values.

Can the SI7060-EVB be used to program custom temperature thresholds?

Yes - the SI7060-EVB supports full I²C register access, including write capability to OTP registers 0xC6 (sw_op) and 0xC7 (sw_hyst). Using Simplicity Studio or a generic I²C master, users can configure custom operate points (e.g., 85°C) and hysteresis (e.g., 5°C), then enable usestore (bit 6 of register 0xC4) to retain those settings across sleep/wake cycles - a key feature validated on the SI7060-EVB.

Is the SI7060-EVB compatible with standard Arduino or Raspberry Pi I²C interfaces?

Yes - the SI7060-EVB uses standard 0.1″ pitch headers for VDD, GND, SCL, and SDA, matching common 3.3 V or 5 V microcontroller I²C levels. Pull-up resistors (typically 4.7 kΩ) are pre-installed and compatible with Arduino Uno (5 V), Raspberry Pi (3.3 V), and most ARM Cortex-M development boards without modification or level-shifting circuitry.
