Overview
The AS1100WL is a serially interfaced LED driver designed for 7-segment numeric displays with up to 8 digits. It operates on a supply voltage range of 2.7V to 5.5V and draws a typical supply current of 330 mA. The device features a 10MHz serial interface, individual segment control, and digital/analog brightness adjustment. It includes a BCD decoder, multiplex scan circuitry, and 64-bit memory for data retention. The component is housed in a 24-SOIC package (7.50mm width) and supports operation within a temperature range of 0°C to 70°C.
Feature Summary
- Serially interfaced architecture supporting 10MHz clock speeds
- Integrated BCD code-B decoder and multiplex scan circuitry
- 64-bit memory for persistent LED setting storage
- Digital and analog brightness control capabilities
Applications
- Driving common-cathode 7-segment numeric displays
- Multi-digit LED display systems requiring serial control
- Applications needing low-power shutdown modes with data retention
Procurement Notes
Verify the specific ordering suffix to confirm package type and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Check for any product change notices or end-of-life notifications prior to final design approval.
Selection Notes
Select this component when a direct software-compatible replacement for MAX7219 functionality is required in a SOIC package. Ensure the application utilizes common-cathode displays. Verify that the 2.7V to 5.5V supply range aligns with system power rails. Consider the 24-pin footprint constraints during PCB layout.
Part Context
The AS1100WL belongs to the AS1100 series of LED drivers from ams-OSRAM. It is functionally compatible with the MAX7219 but packaged in a 24-SOIC format rather than DIP. The series offers programmable serial interfaces and integrated decoding for simplified microcontroller connections in display applications.
Replacement Considerations
Public confirmed substitute part numbers include AS1100WL-T and AS1100WL-Z. These variants share identical functional descriptions as serially interfaced 8-digit LED drivers. Verify pinout and package dimensions compatibility before substitution.
