The maximum operating temperature range for the MSP430FR5948IRHAT is -40°C to 85°C, as specified in the datasheet. However, it's essential to note that the device can operate at a reduced frequency and voltage at higher temperatures.
To configure the MSP430FR5948IRHAT for low-power mode, you need to use the Power Management Module (PMM) and configure the device to enter Low Power Mode 3 (LPM3) or Low Power Mode 4 (LPM4) depending on your application requirements. This can be done by setting the corresponding bits in the PMMCTL0 register.
The maximum current consumption of the MSP430FR5948IRHAT varies depending on the operating frequency, voltage, and mode. According to the datasheet, the maximum active current is around 2.1 mA at 1 MHz and 2.2 V. However, this value can be reduced by optimizing the clock frequency, voltage, and power modes for your specific application.
Yes, the MSP430FR5948IRHAT can be used with an external crystal oscillator. The device has an internal oscillator that can be used, but an external crystal oscillator can provide better accuracy and stability. The external crystal oscillator can be connected to the XIN and XOUT pins, and the device can be configured to use the external oscillator as the clock source.
The MSP430FR5948IRHAT can be programmed using the Texas Instruments Code Composer Studio (CCS) integrated development environment (IDE) or the IAR Embedded Workbench. You can also use the MSP430 Flasher tool or the UniFlash tool to program the device. The device can be programmed through the Spy-Bi-Wire (SBW) interface or the Joint Test Action Group (JTAG) interface.
