908E624
Functional Description
Functional Device Operation
Watchdog Configuration
If the WDCONF terminal is left open, the default watchdog
period is selected (typ. 150 ms). If no watchdog function is
required, the WDCONF terminal must be connected to GND.
The watchdog period is calculated using the following
formula:
tPWD [ms] = 0.991 * REXT [k] + 0.648
VOLTAGE REGULATOR
The 908E624 chip contains a low-power, low dropout
voltage regulator to provide internal power and external
power for the MCU. The on-chip regulator consist of two
elements, the main voltage regulator and the low-voltage
reset circuit.
The VDD regulator accepts an unregulated input supply
and provides a regulated VDD supply to all digital sections of
the device. The output of the regulator is also connected to
the VDD terminal to provide the 5.0 V to the microcontroller.
Current Limit (Overcurrent) Protection
The voltage regulator has current limit to protect the device
against overcurrent and short circuit conditions.
Overtemperature Protection
The voltage regulator also features an overtemperature
protection having an overtemperature warning (Interrupt -
VDDT) and an overtemperature shutdown.
Stop Mode
During Stop mode the Stop mode regulator supplies a
regulated output voltage. The Stop mode regulator has a
limited output current capability.
Sleep Mode
In Sleep mode the voltage regulator external VDD is turned
off.
FACTORY TRIMMING AND CALIBRATION
To enhance the ease-of-use of the 908E624, various
parameters (e.g., ICG trim value) are stored in the flash
memory of the device. The following flash memory locations
are reserved for this purpose and might have a value different
from the “empty” (0xFF) state:
0xFD80:0xFDDF Trim and Calibration Values
0xFFFE:0xFFFF Reset Vector
In the event the application uses these parameters, one
has to take care not to erase or override these values. If these
parameters are not used, these flash locations can be erased
and otherwise used.
OPERATING MODES OF THE MCU
For a detailed description of the operating modes of the
MCU, refer to the MC68HC908EY16 datasheet.
