Product details

Overview

STM8T143-EVAL from STMicroelectronics is an evaluation kit designed to accelerate development of capacitive touch and proximity sensing applications using the STM8T143AM62 microcontroller. It includes a controller board (MB972), a programming/data streaming board (MB973), five interchangeable electrode boards, and supports standalone, programming, and data streaming modes via USB or ST-TSLINK interface.

For engineers reviewing the STM8T143-EVAL datasheet, STM8T143-EVAL pinout, STM8T143-EVAL application, or STM8T143-EVAL equivalent, this kit enables rapid validation of capacitive sensing performance, real-time parameter monitoring in STM Studio, firmware configuration via STVP, and electrode layout optimization across five distinct ground-plane configurations.

Technical Context

The STM8T143-EVAL implements a complete hardware platform for evaluating the STM8T143's integrated capacitive sensing peripheral (TSI), supporting both proximity and touch detection with configurable thresholds and filtering. It uses the SO8-packaged STM8T143AM62 MCU, which features 8 KB Flash, 1 KB RAM, and dedicated TSI analog front-end with up to 16 channels.

Three operational modes are supported: Standalone mode (USB-powered, LED feedback only), Programming mode (ST-TSLINK + STVP for option byte configuration), and Data Streaming mode (ST-TSLINK + STM Studio for live internal register and sensor parameter visualization). Electrode boards connect via CN3/CN4 headers with RC-filtered inputs and configurable CX/VREG routing via SB1/SB2 solder bridges.

Key Specifications

Parameter	Value and Actual Design Meaning
Core MCU	STM8T143AM62 in SO8 package - provides integrated TSI peripheral, 8 KB Flash, and low-power operation for touch/proximity sensing.
Controller Board	MB972 - hosts MCU, LD1/LD2 LEDs, JP1 IDD jumper, SB1/SB2 solder bridges, and CN1–CN4 connectors for expansion and programming.
Data Streaming Interface	ST-TSLINK dongle + STM Studio GUI - enables real-time readout of TSI internal registers (e.g., counter values, baseline, delta) at up to 100 Hz.
Programming Interface	ST-TSLINK + ST Visual Programmer (STVP) - configures one-time programmable option bytes for sensor sensitivity, debounce, and output behavior.
Electrode Support	Five plug-in boards (MB974, MB975, MB976, MB1022, MB1025) - each with unique ground plane geometry (0%, 15%, 100%, ring+plane, ring-only) for systematic noise and sensitivity testing.
Power Options	USB 5 V (via CN5) or ST-TSLINK VDD_PROG (3.3 V) - selectable via JP1 and SB2; supports current measurement via open-jumper ammeter connection.

FAQ

What software tools are required to use the STM8T143-EVAL?

You need ST Visual Programmer (STVP) for configuring option bytes and STM Studio for real-time data streaming and internal register monitoring. Both are free downloads from st.com. The kit requires Windows XP/Vista/7 and the ST-TSLINK programming dongle for full functionality - USB connection alone supports only basic standalone mode with LED feedback.

Can I replace the STM8T143AM62 MCU on the MB972 board?

Yes - the STM8T143AM62 is socketed in an SO8 footprint on the MB972 controller board, allowing physical replacement with another STM8T143 device for testing or recovery. No rework is needed; the SO8 pad layout matches standard JEDEC SOIC-8 dimensions and thermal profile.

How do the five electrode boards differ in function?

Each board varies grounding topology to isolate design variables: MB974 (no ground plane), MB975 (15% ground), MB976 (100% ground), MB1022 (ground ring + plane), and MB1025 (ring-only). This enables empirical study of how ground coupling affects signal-to-noise ratio, detection range, and false-trigger immunity in real-world layouts.

Is the STM8T143-EVAL compatible with newer ST development tools?

While officially validated with STVP and STM Studio on Windows XP–7, the kit's ST-TSLINK interface remains electrically compatible with modern STLINK-V3SET debuggers using appropriate adapter cables and updated STSW-LINK007 firmware. However, STM Studio has been superseded by STM32CubeMonitor; legacy support for STM8T143 remains functional but unmaintained.
