STMicroelectronics STEVAL-MKI200V1K

Overview

STEVAL-MKI200V1K from STMicroelectronics is a ready-to-use temperature probe evaluation kit built around the STTS22H ultralow-power I²C/SMBus 3.0 temperature sensor, featuring ±0.5°C accuracy over –20°C to +85°C, 1.7–3.6 V supply range, and housed in a miniature 1.4 × 1.1 mm DFN6 package mounted at the tip of a thin flexible probe for minimal thermal interference.

For engineers reviewing the STEVAL-MKI200V1K datasheet, STEVAL-MKI200V1K pinout, STEVAL-MKI200V1K application, or STEVAL-MKI200V1K equivalent, this kit enables rapid validation of remote temperature sensing in space-constrained, low-power embedded systems interfaced via STEVAL-MKI109V3/STEVAL-MKI109D platforms and MEMS Studio GUI.

Technical Context

The kit implements a two-board architecture: the STEVAL-MKI200V1 probe board hosts the STTS22H sensor with on-board decoupling (1 µF + 100 nF), while the STEVAL-MKIGIBV1 adapter provides full DIL24 socket compatibility and routes SCL/SDA, INT1/INT2, VDD, and Vdd_IO to match STEVAL-MKI109V3/D host platforms.

It leverages the STTS22H's SMBus Alert Response Address (ARA) support, programmable conversion rate (up to 16 Hz), and interrupt-driven operation (DRDY, INT1/INT2) to enable autonomous thermal monitoring without continuous polling - critical for battery-powered metering and portable diagnostics.

FAQ

Does STEVAL-MKI200V1K include the STEVAL-MKI109V3 or STEVAL-MKI109D platform?

No. The STEVAL-MKI200V1K kit contains only the STTS22H probe board and the STEVAL-MKIGIBV1 adapter board. It requires either the STEVAL-MKI109V3 or STEVAL-MKI109D development platform to operate - both sold separately and serve as the host MCU bridge to PC via USB.

What software is needed to interface with the STEVAL-MKI200V1K?

ST's free MEMS Studio graphical user interface (downloadable from st.com) is fully supported. It auto-detects the STTS22H via the host platform, enabling real-time temperature plotting, register configuration, interrupt setup, and data logging without custom code.

Can the STTS22H sensor be replaced or reworked on the probe board?

No. The STTS22HTR is soldered in a 1.4 × 1.1 mm DFN6 package directly onto the flexible probe PCB. Its placement and thermal isolation are factory-optimized; replacement would compromise calibration integrity and mechanical robustness of the probe tip.

Is the probe cable length customizable or extendable?

The standard probe uses a fixed-length flat flexible cable optimized for signal integrity and mechanical durability. ST does not offer custom lengths; however, users may extend SCL/SDA lines using shielded twisted-pair wiring if maintaining SMBus timing margins and noise immunity is verified per application requirements.
