AS1108 - 4-Digit LED Display Driver

Datasheet Summary

Description

The AS1108 is a compact display driver for 7-segment numeric displays of up to 4 digits.

The device can be programmed via SPI, QSPI, and Microwire as well as a conventional 4-wire serial interface.

Features

  • ! ! ! ! ! ! ! ! ! ! ! The AS1108 features an extremely low shutdown cur! rent of typically 3µA, and an operational current of less ! than 500µA. The number of digits can be programmed, - 20-pin DIP the device can be reset by software, and an external DataSheet4U. com - 20-pin SOIC clock is also supported. Additionally, segment blinking can be synchronized across multiple drivers. The AS1108 provides several test modes for easy.

The device can be programmed via SPI, QSPI, and Microwire as well as a conventional 4-wire serial interface. The device 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. Every segment can be individually addressed and updated separately. Only one external resistor (RSET) is required to set the current through the LED display. LED brightness can be controlled by analog or digital means.
