ISSI Announces Full Function LED Driver IC For Automotive Interior Lighting

ISSI Full Function LED Driver IC For Automotive Interior Lighting

150mA Linear LED Driver with Push-Button Input Combined with Courtesy Signal

Integrated Silicon Solution, Inc. (ISSI), a leader in advanced memory and analog IC solutions, has announced a single chip solution for automotive interior lighting.

The IS32LT3175 is a feature-rich AEC-Q100 certified linear LED driver enabling reduced BOM count for low-cost and compact designs.


Key features and benefits of the IS32LT3175 include:

  • Reduced BOM: LED driver with theatrical dimming in one small 8 pin SOP package resulting in 65% less components requiring less printed circuit board area.
  • Linear LED Driver: Low-noise, low-EMI, linear current source adjustable from 10~150 mA into one or more LEDs.
  • Switch Input: Integrates switch debounce and latching logic to enable use of low cost momentary contact switch. The switch On/Off state is held during start-stop operation when voltage drops below 6V for a short period of time.
  • Local or Remote: Can be controlled remotely by the automobile’s microcontroller or locally with a momentary contact switch. The local switch has priority over the remote microcontroller providing the user with direct control of the LED lamp.
  • No Microcontroller: Advanced LED performance can be adjusted with simple resistors, eliminating the need for a microcontroller.
  • AEC-Q100: Meets stress testing specifications making it suitable for use in the harsh automotive environment with guaranteed operation from –40°C to +125°C.

Configurable Advanced Touch-Screen LCD Video Evaluation Platform for Lattice FPGA Families

Configurable Advanced Touch-Screen LCD Video Evaluation Platform for Lattice FPGA Families

Lattice Semiconductor Corporation has announced the release of LCD-Pro, an advanced FPGA-based LCD video imaging and control solutions platform.

The LCD-Pro evaluation platform is based on the low-cost LatticeECP2
and LatticeXP2(TM) FPGA devices, and the UltiLogic family of graphics Intellectual Property (IP) Cores from Exor International. The LCD-Pro platform addresses a wide range of active matrix TFT displays from 2 inches to 23 inches, and enables rapid evaluation of advanced LCD video and touch-screen controller IP designed to accelerate time-to-market for manufacturers developing LCD video display and HMI (Human-Machine Interface) applications in automotive, consumer, white goods, building automation and industrial control markets.

Designed to provide comprehensive graphic processing functionality, the LCD-Pro platform incorporates a 2D graphics accelerator and can handle picture scaling and the cropping of real-time video. An I2C interface facilitates “plug-and-play” LCD connectivity while a backlight inverter provides ON/OFF and dimming control.

The LCD-Pro evaluation kit includes

  • Carrier Board including 2x CVBS and 1x VGA Video Input Ports
  • LatticeECP2-50 based FPGA module
  • 7″ WVGA LCD Color Touch Display
  • Color Video Camera
  • 12 VDC Power Supply  
  • USB 2.0 Cable
  • Adapter for Lattice JTAG Cable
  • FPGA: LFE2-50E 5FN484C
  • SPI Flash
  • M25P32 – 4Mx8bit DDR Video Memory 64MB (32Mx16bit)
  • 48MHz Oscillator
  • JTAG port
  • Analog circuits for A/D-D/A converters,
  • Analog front end for Video Input,
  • Universal LCD and Touch Screen connectors
