Manufacturer: Intersil (now Renesas)

Overview: CDP68HC68W1 March 1998 CMOS Serial Digital Pulse Width Modulator.

General Description

The CDP68HC68W1 modulates a clock input to supply a variable frequency and duty-cycle output signal.

Three 8-bit registers (pulse width, frequency and control) are accessed serially after power is applied to initialize device operation.

The value in the pulse width register selects the high duration of the output period.
