STEVAL-LLL002V1 Data brief Evaluation kit for automotive rear lights with pattern animations based on ALED1262ZT and STM8AF6266 Features Various pre-configured and programmable patterns on the 12 x 4 red LED matrix 7 bit PWM local dimming control with non-linear steps to adjust brightness to human eye perception Speed control Push buttons to switch modes Safety standalone mode function and OTP pre-programmed mode for custom configuration Fast IC interface with selectable extended Hamming encoding Open error simulation and real-time detection 12 to 24 V DC power supply with reverse polarity protection GUI for advanced driver configuration Product summary USB-UART bridge (STEVAL-LLL002D1) for PC connection RoHS and WEEE compliant Evaluation kit for automotive rear lights with pattern STEVAL-LLL002V1 animations based Description on ALED1262ZT The STEVAL-LLL002V1 evaluation kit consists of the STEVAL-LLL002M1 main and STM8AF6266 board and the STEVAL-LLL002D1 USB-UART bridge. Main board with STEVAL-LLL002M1 It has been designed to test and evaluate ALED1262ZT performance. ALED1262ZT LED (not available driver separately) The STEVAL-LLL002M1 is a LED array driver system evaluation board with local STEVAL-LLL002D1 dimming and diagnostics for automotive applications. It is based on the ALED1262ZT USB-UART bridge (not available 12-channel LED driver controlled through the STM8AF6266 microcontroller IC separately) interface. GUI for STEVAL- A 48 red LED matrix is driven by four ALED1262ZT LED drivers. LLL002V1 The on-board A7986A DC-DC converter, accepting standard adapter input voltages evaluation kit for STSW-LLL002V1 rear automotive with reverse polarity protection, provides the voltages and power for the board lighting applications operation. Automotive-grade The STEVAL-LLL002V1 evaluation kit jumpers simulate LED open circuit faults and 12-channel LED ALED1262ZT the 4-pin SWIM connector is used to debug and develop the STM8AF6266 driver microcontroller firmware. Automotive 8-bit The evaluation kit can operate in bus driven mode (BDM), standalone mode (SAM) MCU with 32 and GUI mode. Kbytes Flash, LIN, STM8AF6266 16 MHz CPU, In the bus driven mode, the board is controlled via on-board push buttons and integrated potentiometers. Commands to the ALED1262ZT driver are sent by STM8A EEPROM microcontroller over IC bus. 3 A step-down In the standalone mode, the STEVAL-LLL002V1 evaluation kit is not controlled by the switching regulator A7986A MCU and you can select two possible output configurations using OTP SPDT for automotive switch (SW2). applications In the GUI mode, the board is connected to a PC via USB-UART bridge and you can observe and control various features of the driver through the graphical user interface.
