ISL29501-CS-EVKIT1Z
Cat Shark Reference Design
The ISL29501-CS-EVKIT1Z is a distance
measurement reference design consisting of an
optical board and a controller board. It combines the
ISL29501
chip with an OSRAM SFH 4550 IR emitting
LED and OSRAM SFH 213FA photodiode. The two
circuit boards are connected together with a flat flex
cable. Included is a USB flash drive containing the
evaluation software for a PC and related technical
documents.
The ISL29501-CS-EVKIT1Z kit also allows quick
evaluation of the ISL29501 performance for a 2m
sensing system.

  • Page 3: Functional Description

    Before meaningful measurements can be made the calibration registers in the chip need to be loaded. This can be done in two ways. The first is to load a profile that contains data into the GUI. This can be one of the Renesas provided profiles or one that was saved previously by the user.

  • Page 4: Operating Range

    The process for collecting data is described in AN1967, ISL29501 Temperature and Ambient Light Data Collection. Renesas strongly recommends that customers evaluate these parameters as a last step in their evaluation. To avoid temperature effects low integration times, reg 0x10 < 0x06 should be used.
