LPC2478FET208 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the LPC2478FET208?
  The maximum operating temperature range for the LPC2478FET208 is -40°C to +105°C, but it can be extended to -40°C to +125°C with some limitations on the clock frequency and voltage supply.
• How do I configure the external memory interface (EMI) for the LPC2478FET208?
  The EMI configuration for the LPC2478FET208 involves setting the EMI registers, configuring the memory timing, and enabling the EMI clock. Refer to the LPC2478 user manual and the example code provided by NXP for more details.
• Can I use the LPC2478FET208 with a 3.3V power supply?
  Yes, the LPC2478FET208 can operate with a 3.3V power supply, but it requires an external voltage regulator to generate the internal 1.2V core voltage. Additionally, some peripherals may not function correctly at 3.3V, so ensure to check the datasheet and user manual for specific details.
• How do I implement a secure boot mechanism on the LPC2478FET208?
  The LPC2478FET208 has a built-in ROM-based boot loader that can be used to implement a secure boot mechanism. This involves generating a secure boot image, storing it in the on-chip flash, and configuring the boot loader to authenticate the image before booting. Refer to the LPC2478 user manual and the NXP secure boot application note for more details.
• What is the maximum clock frequency for the LPC2478FET208?
  The maximum clock frequency for the LPC2478FET208 is 72 MHz, but it can be overclocked to 100 MHz with some limitations on the voltage supply and temperature range.
