Features & Applications

Austriamicrosystems designs, manufactures and markets high performance analog integrated circuits for communications, industrial, medical and automotive markets building on more than 25 years of analog design capabilities, system know-how, and own state-of-the-art manufacturing and test facilities.

Austriamicrosystems’ focuses on power management, sensors & sensor interfaces, portable audio and car access applications, and offers the industry's broadest range of high performance absolute and incremental rotary and linear magnetic encoder devices that are complete SoC solutions integrating Hall element, analog front end and digital signal processing.

AS1115 is an easy to use user interface (UI) LED driver. The AS1115 combines display driving and key scanning providing a complete front panel solution which eliminates the use of secondary µP or other logics plus discrete devices, reducing BOM count and cost.

The AS1115 can drive either eight 7-segment digits or 64 individual LEDs with 47mA per digit or 5mA per LED. An external resistor can easily adjust the current. With an excellent accuracy of ±3%, the AS1115 improves picture quality for LED displays, this is due to minimized intensity variations between the LEDs and LED modules. For either global digital brightness control, or separate dimming, of each single digit a 4-bit PWM is implemented. Additionally the AS1115 offers the read back of up to 16-keys completing the single chip UI solution.

The AS1115 operates from a single 2.7V to 5.5V supply while requiring the lowest supply current of 0.6mA during operation and 200nA in shutdown mode. The AS1115 interfaces via I²C and up to four devices can be addressed on a single I²C bus.

The AS1115-BSST is suitable for operating environments ranging from -40 to +85°C and requires a minimum of external components reducing system costs to a minimum. Optimized for easy handling the AS1115-BSST comes in a QSOP 24-pin package.
