LPC1313FBD48 datasheet by NXP Semiconductors

LPC1313FBD48 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be achieved with the internal oscillator?
  The maximum clock frequency that can be achieved with the internal oscillator is 12 MHz. However, it's recommended to use an external crystal oscillator for more accurate and stable clock frequencies.
• How do I configure the pin multiplexing to use the desired peripherals?
  The pin multiplexing can be configured using the PINSELx registers. Each peripheral function has a specific pin assignment, and the PINSELx registers allow you to select which function is assigned to each pin. Refer to the datasheet and the LPC1313 user manual for more information.
• What is the maximum current that can be sourced or sunk by the GPIO pins?
  The maximum current that can be sourced or sunk by the GPIO pins is 4 mA. However, it's recommended to limit the current to 2 mA or less to ensure reliable operation and to prevent overheating.
• How do I implement a low-power mode to reduce power consumption?
  The LPC1313 has several low-power modes, including Sleep, Deep Sleep, and Power-Down modes. These modes can be entered using the PCON register. Additionally, you can use the ARM Cortex-M3's built-in sleep modes, such as WFI (Wait For Interrupt) and WFE (Wait For Event). Refer to the datasheet and the LPC1313 user manual for more information.
• What is the minimum voltage required for the device to operate correctly?
  The minimum voltage required for the LPC1313 to operate correctly is 2.4 V. However, it's recommended to operate the device at a voltage between 2.7 V and 3.6 V for optimal performance and reliability.
