LPC2141FBD64 datasheet by NXP Semiconductors

LPC2141FBD64 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the LPC2141FBD64?
  The maximum clock frequency for the LPC2141FBD64 is 60 MHz, but it can be overclocked up to 70 MHz with some limitations. However, it's recommended to follow the datasheet specifications to ensure reliable operation.
• How do I configure the pin multiplexing on the LPC2141FBD64?
  The pin multiplexing on the LPC2141FBD64 is configured using the PINSEL registers. Each peripheral function has a corresponding PINSEL register that determines which pins are used for that function. Consult the datasheet and user manual for specific register settings and pin assignments.
• Can I use the LPC2141FBD64 with a 3.3V power supply?
  Yes, the LPC2141FBD64 can operate with a 3.3V power supply. However, the maximum operating frequency may be limited to 48 MHz at 3.3V. Consult the datasheet for specific voltage and frequency limitations.
• How do I implement a bootloader on the LPC2141FBD64?
  Implementing a bootloader on the LPC2141FBD64 involves creating a program that can load and execute firmware from an external source, such as a serial interface or flash memory. NXP provides a bootloader example in the LPC214x user manual, and there are also third-party bootloader solutions available.
• What is the maximum amount of RAM and flash memory available on the LPC2141FBD64?
  The LPC2141FBD64 has 32 KB of SRAM and 64 KB of flash memory. However, some of the flash memory is used for the bootloader and other system functions, so the available user flash memory is approximately 58 KB.
