MSP430F5309IRGCT datasheet by Texas Instruments

MSP430F5309IRGCT Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the MSP430F5309IRGCT?
  The maximum operating frequency of the MSP430F5309IRGCT is 25 MHz, but it can be overclocked to 30 MHz with reduced voltage and temperature range.
• How do I configure the MSP430F5309IRGCT for low-power operation?
  To configure the MSP430F5309IRGCT 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-Saving Modes (PSM) to reduce power consumption.
• Can I use the MSP430F5309IRGCT with an external crystal oscillator?
  Yes, the MSP430F5309IRGCT 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 MSP430F5309IRGCT?
  The MSP430F5309IRGCT 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 USB interfaces with a bootloader.
• What is the maximum amount of flash memory that can be used for program storage?
  The MSP430F5309IRGCT has 128 KB of flash memory, but only 96 KB is available for program storage. The remaining 32 KB is reserved for the bootloader and other system functions.
