Description
The ASIC consists of a dedicated microcontroller combined with on-chip analog and digital blocks, which can be configured to a great extend. This makes it ideal to adapt it to different applications by means of an update in the software. The number of external components for the electronic module is minimized. A typical application mainly consists of the MLX90719 ASIC, a number of command buttons, a LCD, a relay, some LED’s and a buzzer.
The number of buttons and their function can be freely chosen. The configuration of the LCD, the number of backplanes and its pinout is also under software control. Three outputs are available for a relay and LED’s.

FEATUREs and Benefits
   1µm CMOS technology
   MLX8 core with 8 accumulators, 80 bytes RAM and 6K ROM
   1 high voltage input (detection of mains-active)
   Zero-crossing detection input to detect the 50/60Hz
   7 standard inputs of which 2 can be used as comparator inputs and 2 can be configured as
   open-collector outputs.
   15 configurable LCD outputs (segment/backplane)
   3 relay drivers which can also be used to drive a triac or LED’s without the need for external resistors.
   Buzzer driver with programmable frequency
   On-chip 4MHz oscillator, crystal oscillator and low power RC oscillator
   Low power mode (battery or decoupling capacitor)
   High supply voltage eliminates the need for high power resistors
