AS1116-BSST

Overview

The AS1116-BSST is a compact LED driver designed for 64 single LEDs or eight digits of seven-segment displays. It features an SPI-compatible three-wire interface for programming. The device operates on a supply voltage range of 2.7V to 5.5V and supports an operating temperature range from -40°C to +85°C. It utilizes a surface mount mounting type within a 24-QSOP package.

Feature Summary

• Supports configuration for 64 individual LEDs or eight seven-segment digits
• Utilizes an SPI-compatible three-wire interface for control programming

Applications

• Seven-segment display systems
• Single LED matrix arrays

Procurement Notes

Verify the specific manufacturer designation, as sources list both ams OSRAM and ams-OSRAM USA INC. Confirm the package type is 24-QSOP and check for current availability status, as some distributors indicate limited stock or discontinuation risks for related series components.

Selection Notes

Select this component when an SPI-controlled driver for up to eight seven-segment digits or 64 discrete LEDs is required. Ensure the system voltage falls within the 2.7V to 5.5V range and that the thermal environment stays between -40°C and +85°C.

Part Context

This part belongs to the AS111x family of LED drivers from ams OSRAM. The AS1116 specifically targets applications requiring efficient control of multiple display elements through a serial interface, distinguishing it from parallel-driven counterparts in the same product line.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing PCB footprints and firmware interfaces before considering alternative drivers.
