CLOCK CHARACTERISTICS (Cont’d)
12.5.4 RC Oscillators
The ST7 internal clock can be supplied with an RC
oscillator. This oscillator can be used with internal
or external components (selectable by option
byte).
Figure 69. Typical Application with RC oscillator
Notes:
1. Data based on design simulation.
2. REX must have a positive temperature coefficient (ppm/°C), carbon resistors should therefore not be used.
3. iCEX is the current needed to load the CEX capacitor while OSC1 is forced to VSS or 1.5V (RC oscillation voltage range).
