The ATAM894 contains a clock module with 4 different internal oscillator types: two RC-oscilla-
tors, one 4-MHz crystal oscillator and one 32-kHz crystal oscillator. The pins OSC1 and OSC2
are the interface to connect a crystal either to the 4-MHz, or to the 32-kHz crystal oscillator.
OSC1 can be used as input for external clocks or to connect an external trimming resistor for the
RC-oscillator 2. All necessary circuitry except the crystal and the trimming resistor is integrated
on-chip. One of these oscillator types or an external input clock can be selected to generate the
system clock (SYSCL).
In applications that do not require exact timing, it is possible to use the fully integrated RC-oscil-
lator 1 without any external components. The RC-oscillator 1 center frequency tolerance is
better than ±50%. The RC-oscillator 2 is a trimmable oscillator whereby the oscillator frequency
can be trimmed with an external resistor attached between OSC1 and V
the RC-oscillator 2 frequency can be maintained stable to within a tolerance of ±15% over the
full operating temperature and voltage range.
