The maximum clock frequency for the MSP430F148IPAG is 16 MHz, but it can be overclocked up to 20 MHz with reduced voltage and temperature range.
To configure the MSP430F148IPAG for low power consumption, use the low power modes (LPM0-LPM4) by setting the corresponding bits in the status register, and also use the clock system to reduce the clock frequency or turn off unused peripherals.
Yes, the MSP430F148IPAG can operate with a 3.3V power supply, but the maximum clock frequency is limited to 12 MHz at this voltage. For 16 MHz operation, a 2.2V to 3.6V power supply is required.
The MSP430F148IPAG can be programmed using the Spy-Bi-Wire (SBW) interface or the Joint Test Action Group (JTAG) interface. TI provides the Code Composer Studio (CCS) integrated development environment (IDE) for programming and debugging.
The MSP430F148IPAG has 256 bytes of RAM and 48 KB of flash memory.
