STEVAL-LLL002V1

Evaluation kit consists of the STEVAL-LLL002M1 main board and the STEVAL-LLL002D1 USB-UART bridge. It has been designed to test and evaluate ALED1262ZT performance. The STEVAL-LLL002M1 is a LED array driver system evaluation board with local dimming and diagnostics for automotive applications. It is based on the ALED1262ZT 12-channel LED driver controlled through the STM8AF6266 microcontroller I²C interface. A 48 red LED matrix is driven by four ALED1262ZT LED drivers. The on-board A7986A DC-DC converter, accepting standard adapter input voltages with reverse polarity protection, provides the voltages and power for the board operation. The evaluation kit jumpers simulate LED open circuit faults and the 4-pin SWIM connector is used to debug and develop the STM8AF6266 microcontroller firmware. The evaluation kit can operate in bus driven mode (BDM), standalone mode (SAM) and GUI mode.

• Various pre-configured and programmable patterns on the 12 x 4 red LED matrix
• 7bit PWM local dimming control with non-linear steps
• Speed control, push buttons to switch modes
• Safety standalone mode function and OTP pre-programmed mode for custom configuration
• Fast I²C interface with selectable extended hamming encoding
• Open error simulation and real-time detection
• 12 to 24VDC power supply with reverse polarity protection
• GUI for advanced driver configuration
• USB-UART bridge (STEVAL-LLL002D1) for PC connection
