Instructions for Use
Power Supply:
- Ensure the power supply voltage (VCC) is within the specified range of 2.7 to 5.5V.
- Connect the ground (GND) pin to a stable ground reference.
Clock Configuration:
- Set the CPU clock frequency (fCLK) to a value within the maximum limit of 32 MHz.
- Use the internal oscillator or an external crystal/ceramic resonator as needed.
Memory Management:
- Utilize the 128KB flash memory for storing program code.
- Use the 16KB RAM for temporary data storage during execution.
- Store non-volatile data in the 2KB EEPROM.
Analog-to-Digital Conversion:
- Configure up to 12 ADC channels for analog signal input.
- Set the ADC resolution to 10 bits for accurate conversions.
Timers and Counters:
- Use the 6 available timers for various timing and counting tasks.
- Configure each timer for specific intervals and modes (e.g., PWM, capture).
Communication Interfaces:
- Utilize the 2 UARTs for serial communication with other devices.
- Use the SPI interface for high-speed synchronous data transfer.
- Employ the I2C interface for communication with I2C-compatible devices.
Watchdog Timer:
- Enable the watchdog timer to reset the microcontroller if it becomes unresponsive.
- Configure the watchdog timer period and behavior as required.
Low-Voltage Detection:
- Enable the low-voltage detection feature to monitor the power supply and trigger an interrupt or reset if the voltage drops below a threshold.
Package and Pinout:
- The MB90F497G is available in a QFP-44 package with 44 pins.
- Refer to the pinout diagram in the datasheet for specific pin assignments and connections.
Programming and Debugging:
- Use a compatible programmer to upload code to the flash memory.
- Utilize debugging tools and software to test and debug the application.
For detailed specifications and additional information, refer to the official datasheet and application notes provided by the manufacturer.
