T48C862-R8
4590B–4BMCU–02/03
Figure 23. RC-oscillator 2
4-MHz Oscillator The microcontroller block 4-MHz oscillator options need a crystal or ceramic resonator
connected to the OSC1 and OSC2 pins to establish oscillation. All the necessary oscilla-
tor circuitry is integrated, except the actual crystal, resonator, C3 and C4.
4-MHz Crystal Oscillator
Figure 24. Ceramic Resonator
32-kHz Oscillator Some applications require long-term time keeping or low resolution timing. In this case,
an on-chip, low power 32-kHz crystal oscillator can be used to generate both the
SUBCL and the SYSCL. In this mode, power consumption is greatly reduced. The
32-kHz crystal oscillator can not be stopped while the power-down mode is in operation.
