LPC2458FET180,551 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the LPC2458FET180?
  The maximum operating temperature range for the LPC2458FET180 is -40°C to +105°C.
• How do I configure the clock settings for the LPC2458FET180?
  The clock settings for the LPC2458FET180 can be configured using the PLL (Phase-Locked Loop) and the Clock Generation Unit (CGU). The PLL can be used to generate a clock frequency up to 480 MHz, and the CGU can be used to divide the clock frequency to generate the desired clock speed for the CPU, peripherals, and other components.
• What is the maximum amount of current that the LPC2458FET180 can supply to external devices?
  The maximum amount of current that the LPC2458FET180 can supply to external devices is 4mA per GPIO pin, with a total current limit of 100mA for all GPIO pins combined.
• How do I implement a bootloader for the LPC2458FET180?
  A bootloader for the LPC2458FET180 can be implemented using the In-System Programming (ISP) feature, which allows the microcontroller to be programmed via a serial interface. The bootloader can be stored in the on-chip flash memory and can be used to load and update the application software.
• What is the purpose of the Embedded Trace Macrocell (ETM) in the LPC2458FET180?
  The Embedded Trace Macrocell (ETM) in the LPC2458FET180 is a debugging tool that allows real-time tracing of the processor's instruction and data flows. It provides a way to debug and optimize the system's performance and can be used in conjunction with a debug probe or emulator.
