Oscillator Circuits and External Clock Input Stage
The ATAM893-D series consists of four different internal oscillators: two RC-oscillators, one 4-
MHz crystal oscillator, one 32-kHz crystal oscillator and one external clock input stage.
4.5.2.1
RC-oscillator 1 Fully Integrated
For timing insensitive applications, it is possible to use the fully integrated RC-oscillator 1. It
operates without any external components and saves additional costs. The RC-oscillator 1 cen-
ter frequency tolerance is better than
±50% over the full temperature and voltage range. The
basic center frequency of the RC-oscillator 1 is f
O
4.0 MHz. The RC oscillator 1 is selected by
default after power-on reset.

4.5.2.2
External Input Clock
The OSC1 or OSC2 can be driven by an external clock source provided it meets the specified
duty cycle, rise and fall times and input levels. Additionally, the external clock stage contains a
supervisory circuit for the input clock. The supervisor function is controlled via the OS1, OS0 bit
in the SC register and the CCS bit in the CM register. If the external input clock is missing for
more than 1 ms and CCS = 0 is set in the CM register, the supervisory circuit generates a hard-
ware reset.
