The maximum operating temperature range for the MPC8349ECVVAJFB is -40°C to 105°C (industrial temperature range). However, it's recommended to operate within -20°C to 85°C for optimal performance and reliability.
The DDR2 memory interface on the MPC8349ECVVAJFB can be configured using the DDR2 controller registers. You need to set the memory timing parameters, such as clock frequency, CAS latency, and burst length, according to the DDR2 memory module specifications. Refer to the Freescale Semiconductor application note AN3444 for detailed configuration guidelines.
No, the MPC8349ECVVAJFB requires a 1.0V to 1.2V power supply for the core voltage (VDD) and a 3.3V power supply for the I/O voltage (VDDIO). Using a 3.3V power supply for the core voltage may damage the device or affect its performance.
The MPC8349ECVVAJFB has a built-in watchdog timer (WDT) that can be enabled and configured using the WDT registers. You need to set the watchdog timer period, enable the timer, and implement a reset mechanism to restart the system in case of a timeout. Refer to the Freescale Semiconductor application note AN3445 for detailed implementation guidelines.
The maximum frequency for the e300 core on the MPC8349ECVVAJFB is 667 MHz. However, the actual operating frequency may vary depending on the system design, power supply, and thermal conditions.
