VSC060

Data Sheet

Additional control features include: selectable flash rates for direct LED drive, input edge detection for interrupt

generation, input to output bypass capability, fan speed monitoring control, and pulse-width modulated output

control. Support for sub-addressing additional two-wire serial slave devices using a set of seven control registers is

included. This capability allows up to 24 independent Master mode two-wire serial slave ports to be created using 48

of the I/O pins.

The addressing capability of the VSC060 includes three pins, which are used for device addressing, as well as one pin

that can be used to select two device type identifiers. Sixteen VSC060 devices can be used in a single two-wire serial

interface system.
