MSP430F5309IRGCR datasheet by Texas Instruments

MSP430F5309IRGCR Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the MSP430F5309IRGCR?
  The maximum operating frequency of the MSP430F5309IRGCR is 25 MHz, but it can be overclocked to 30 MHz with reduced voltage and temperature range.
• How do I configure the MSP430F5309IRGCR for low-power operation?
  To configure the MSP430F5309IRGCR for low-power operation, use the Power Management Module (PMM) to select the desired low-power mode (e.g., LPM3 or LPM4), and adjust the clock frequency and voltage levels accordingly. Additionally, use the Low Power Mode (LPM) and the Power Down Mode (PDM) to reduce power consumption.
• Can I use the MSP430F5309IRGCR with an external crystal oscillator?
  Yes, the MSP430F5309IRGCR can be used with an external crystal oscillator. The device has an internal oscillator that can be used as a clock source, but an external crystal oscillator can be used for more accurate clocking. The external crystal oscillator should be connected to the XIN and XOUT pins, and the internal oscillator should be disabled.
• How do I program the MSP430F5309IRGCR?
  The MSP430F5309IRGCR can be programmed using the Texas Instruments Code Composer Studio (CCS) integrated development environment (IDE) or the IAR Embedded Workbench. The device can be programmed using the JTAG or Spy-Bi-Wire interfaces, or using the UART or I2C interfaces with a bootloader.
• What is the maximum amount of flash memory that can be programmed on the MSP430F5309IRGCR?
  The MSP430F5309IRGCR has 128 KB of flash memory, and up to 127.5 KB can be programmed by the user. The remaining 0.5 KB is reserved for the bootloader and other system functions.
