CLOCK AND TIMING CHARACTERISTICS (Cont’d)
15.5.3 Crystal and Ceramic Resonator Oscillators
The ST7 internal clock can be supplied with four
different Crystal/Ceramic resonator oscillators. All
the information given in this paragraph are based
on characterization results with specified typical
external components. In the application, the reso-
nator and the load capacitors have to be placed as
close as possible to the oscillator pins in order to
minimize output distortion and start-up stabiliza-
tion time. Refer to the crystal/ceramic resonator
manufacturer for more details (frequency, pack-
age, accuracy...).
15.5.3.1 Typical Crystal Resonators
Figure 67. Application with a Crystal Resonator
Notes:
1. Resonator characteristics given by the crystal manufacturer.
2. tSU(OSC) is the typical oscillator start-up time measured between VDD=2.8V and the fetch of the first instruction (with a
quick VDD ramp-up from 0 to 5V (<50s).
3. The oscillator selection can be optimized in terms of supply current using a high quality resonator with small RS value.
Refer to crystal manufacturer for more details.
