ISL97671/2/3/4IRZ-EVAL Quick Start Guide
This quick start guide pertains to the
ISL97671/2/3/4IRZ-EVAL Evaluation Board. This board
comes populated with 72 LEDs in a 6P12S
configuration to simplify evaluation and testing. Please
install the Sunlight ISL97670 GUI from Intersil's
website, which will be used to control ISL97671/3/4
2
parts via I
C. Note the slave address on the ISL97671,
ISL97673 and ISL97674 is hexadecimal 58; see Figure
1. Please refer to "ISL97671" on page 1, "ISL97672"
on page 2, "ISL97673" on page 2 and "ISL97674" on
page 3, for jumper settings and power-up instructions.
