The MC14541B programmable timer consists of a 16stage binary counter, an integrated oscillator for use with an external capacitor and two resistors, an automatic poweron reset circuit, and output control logic. Timing is initialized by turning on power, whereupon the poweron reset is enabled and initializes the counter, within the specified VDD range. With the power already on, an external reset pulse can be applied. Upon release of the initial reset command, the oscillator will oscillate with a frequency determined by the external RC network. The 16stage counter divides the oscillator frequency (fosc) with the nth stage frequency being fosc/2n. Available Outputs 28, 210, 213 or 216 Increments on Positive Edge Clock Transitions Builtin Low Power RC Oscillator ( 2% accuracy over temperature range and 20% supply and 3% over processing at < 10 kHz) Oscillator May Be Bypassed if External Clock Is Available (Apply external clock to Pin 3)
