IS31FL3747-CLS4-TR

Overview

The IS31FL3747-CLS4-TR is a general-purpose 12x12 dots matrix LED driver manufactured by Lumissil Microsystems. It supports configurable matrix sizes of 12 x n, where n ranges from 1 to 12. The device features a 12MHz SPI or 30MHz VSB compatible interface for programming. It operates within a supply voltage range of 2.7V to 5.5V and utilizes a WLCSP-36 package.

Feature Summary

• Supports configurable 12 x n dot matrix configurations with up to 144 LEDs
• Features high-speed digital interfaces including 12MHz SPI and 30MHz VSB compatibility
• Designed for general-purpose LED matrix driving applications

Applications

• LED matrix displays
• Dot matrix signage
• General-purpose LED lighting control

Procurement Notes

Verify the specific suffix CLS4 against the official datasheet to confirm package type and tape-and-reel specifications. Ensure interface requirements match the 12MHz SPI or 30MHz VSB capabilities. Confirm operating voltage compatibility with the 2.7V to 5.5V range before integration into the final design.

Selection Notes

Select this component when a compact 12x12 LED matrix solution is required. The choice depends on the need for high-speed SPI or VSB interfacing and the specific WLCSP-36 footprint constraints. Evaluate power consumption against the 2.7V to 5.5V supply capability.

Part Context

This part belongs to the IS31FL37xx series of LED drivers from Lumissil Microsystems. The series focuses on matrix LED driving solutions with programmable interfaces. The IS31FL3747 specifically targets 12-column matrix architectures, distinguishing it from other series members with different column counts.

Replacement Considerations

Check for direct substitutes within the IS31FL37xx family that offer identical pinouts and interface speeds. Verify if alternative packages are available for the same functional core if layout changes are permitted.
