Product Summary

The AS1108WL is a compact display driver for 7-segment numeric displays of up to 4 digits. The AS1108WL can be programmed via SPI, QSPI, and Microwire as well as a conventional 4-wire serial interface. The AS1108WL includes an integrated BCD code-B/HEX decoder, multiplex scan circuitry, segment and display drivers, and a 32-bit memory. Internal memory stores the LED settings, eliminating the need for continuous device reprogramming. The AS1108WL is ideal for bar-graph displays, instrumentpanel meters, LED matrix displays, dot matrix displays, set-top boxes, white goods, professional audio equipment, medical equipment, industrial controllers and panel meters.
