System Timing
For maximum versatility, the MAXQ3210 generates its
internal system clock from several sources:
External clock source, including low-cost operation
from 3.58MHz “Colorburst” crystal
External crystal or ceramic resonator, using the
internal oscillator
External RC, using the internal relaxation oscillator
Internal ring oscillator
A crystal warmup counter enhances operational relia-
bility. Each time the external crystal oscillation must
restart, such as after exiting stop mode, the device initi-
ates a crystal warmup period of 65,536 oscillations.
This allows time for the crystal amplitude and frequency
to stabilize before using it as a clock source. While in
the warmup mode, the device operates from the inter-
nal 8kHz ring oscillator and can optionally switch back
to the crystal as soon as the warmup period expires.
Internal Voltage Regulator
The MAXQ3210 features an internal voltage regulator that
allows it to be powered from an external battery ranging
from approximately 6.0V to 9.5V. A low-battery detect fea-
ture can set a flag and/or trigger an interrupt when
enabled and the battery voltage falls below the VBF
threshold. The battery voltage is regulated to an internal
voltage (VDDINT) of approximately 5V. The REGOUT out-
put pin provides 5V for use by external devices.
