Description

The IC E910.52 is intended to reduce the costs of products with a large number of inputs and also to reduce software overhead by generating an interrupt on pin change. To decrease the system power dissipation the external driver transistors are only active for 20s of a 7ms frame corresponding to 140 Hz polling frequency.

All inputs E910.52 are compared internal reference. The comparator outputs are debounced and can be monitored by the SPI.
