STEVAL-ILL060V1

STEVAL-ILL060V1 High brightness LED array driver with diagnostics for automotive applications based on the STAP16DPPS05 and STM8A Data brief Description The STEVAL-ILL060V1 is a high brightness LED array driver evaluation board with diagnostics based on STMicroelectronics’ automotive-grade low voltage, 16-bit constant current LED sink driver STAP16DPPS05. The LED driver is configured and controlled through an 8-bit automotive-grade STM8A microcontroller via an SPI interface. An A5974D DC-DC converter, also automotive-grade, provides the voltages and power needed for overall operation of the board. Features • 6 - 24 VDC power supply with reverse voltage protection, short-circuit protection and input surge protection and standard DC jack input • Backward/forward transition switch to change modes • SWIM connector for MCU programing and debugging • Connector for LIN development and evaluation • Potentiometer to change brightness and speed of patterns • 32 white LEDs (PLCC 4) • 8 jumpers to simulate open-circuit error • 4 jumpers, to simulate short-circuit error • USB-UART bridge to interface board with GUI • Demonstrates pre-configured patterns (with adjustable brightness/speed) such as rolling text, wave effect, dot sequence, etc. in standalone mode • Demonstrates basic mode or frame programming mode with GUI SW • RoHS compliant May 2014 DocID026325 Rev 1 For further information contact your local STMicroelectronics sales office. 1/7 www.st.com Schematic diagrams 1 STEVAL-ILL060V1 Schematic diagrams Figure 1.
