IS32LT3134 12-CHANNEL LED ANIMATION CONTROLLER

IS32LT3134 is a 12-channel LED driver with an embedded animation controller. Multiple IS32LT3134 devices can be cascaded in the same board design. Four animation patterns and pin-select information can be stored in the embedded Flash of each device. The patterns are played by a host which controls the input pins of the devices. For each pattern, two modes ca.

Features

July 2022
• Supply voltage range: 3.0V to 5.5V
• UART interface operates at 19.2K baud rate and supports dynamic addressing mode
• 12-channel push-pull output driver for the common anode, common cathode, or multiplexed LED drive modes
• Duration of animation is from 0.1s to 15s
• User programmable internal clock pre-scalar
• Four pattern banks with 12KB Flash each
• Watchdog timer monitors valid clock signals and end of animation pattern. A fault is asserted when errors are detected by the WDT
• Animation-end pin signals the end of a synchronous pattern for all devices, a start of animation .
