MILPITAS, CA: March 16, 2021 – LUMISSIL MICROSYSTEMS, a Division of ISSI, today announced the IS32LT3134

– A 12-channel animation controller for automotive and industrial applications. Up to 4 animation can be stored

on device Flash, and multiple devices connected in series can play patterns simultaneously or cascaded. System

configurations determine clock source, Fault response modes, Global or local LED dimming, LED channel skew to

prevent large current transients etc. 12-channel push-pull outputs driver offer common anode, common

cathode, or multiplexed LED drive options. Beside direct LED drive, the LED control output can drive a LED Driver

device or FETs.

“Major Auto manufacturers are adopting animated lighting functions in car design as a brand differentiator as

well as to address aesthetics, functionality and safety” said Ven Shan, VP of Marketing at Lumissil Microsystems.

“IS32LT3134 is a unique LED Controller that enables animation lighting for a variety of interior and exterior

lighting applications such as animated tail light, DRL, welcome light, emergency light to name a few. The device

is simple to use and integrates fault protection features and is fully AEC Q100 Automotive qualified.”

IS32LT3134 is supplied as a turn-key product with a standard code. A simple device configuration PC-GUI control

devices through UART interface, and is used to load and organize animation patterns to specific devices, select

pattern playback parameters (Synchronized or cascaded playback, global or local dimming, clock division etc.),

and configure system parameters (Clock source, debounce, fault configuration). A complete configuration can be

uploaded, downloaded and executed from the GUI. No programming is required. A complete development

package for IS32LT3134 is available on Lumissil’s website including documentation, evaluation boards and

configuration GUI. Product design and debugging support is available from Lumissil’s application team.
