LPC3141FET180 Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the LPC3141FET180?
  The maximum operating temperature range for the LPC3141FET180 is -40°C to +85°C, but it can be extended to -40°C to +105°C with some limitations on the clock frequency and voltage supply.
• How do I configure the boot mode of the LPC3141FET180?
  The boot mode of the LPC3141FET180 can be configured using the BOOTCFG pins. The BOOTCFG pins are sampled during reset and determine the boot mode. The boot mode can be set to boot from the internal flash, external flash, or SPIFI flash.
• What is the maximum clock frequency that can be achieved with the LPC3141FET180?
  The maximum clock frequency that can be achieved with the LPC3141FET180 is 180 MHz, but it depends on the voltage supply and operating temperature. At 1.2V, the maximum clock frequency is 120 MHz, and at 1.8V, the maximum clock frequency is 180 MHz.
• How do I implement a secure boot mechanism on the LPC3141FET180?
  The LPC3141FET180 has a built-in secure boot mechanism that uses a 128-bit AES encryption engine. The secure boot mechanism can be implemented using the ROM-based boot loader and the One-Time Programmable (OTP) memory. The OTP memory is used to store the encryption key and the boot loader configuration.
• What is the power consumption of the LPC3141FET180 in different operating modes?
  The power consumption of the LPC3141FET180 varies depending on the operating mode. In active mode, the power consumption is around 250 mA at 180 MHz. In sleep mode, the power consumption is around 10 mA, and in deep sleep mode, the power consumption is around 1 mA.
