CLOCK AND TIMING CHARACTERISTICS (Cont’d)
Table 22. Typical Ceramic Resonators for Automotive Applications
Notes:
1. Murata Ceralock (refer to Table 23 for correlation factor)
2. VDD 4.5 to 5.5V
3. Values in parentheses refer to the capacitors integrated in the resonator
Figure 65. Typical Application with Ceramic Resonator
Notes:
1. Resonator characteristics given by the ceramic resonator 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 (<50µs).
3. The oscillator selection can be optimized in terms of supply current using an high quality resonator with small RS value.
Refer to ceramic resonator manufacturer for more details.
