For serial communication the part provides I²C, IrDA, SPI, and UART/USART interfaces. An internal oscillator is available, and the data converter block integrates a 10-channel, 10-bit ADC. These resources suit a sensor-node or data-acquisition front end where the 10-bit ADC resolution is adequate for monitoring temperature, pressure, or voltage levels.
Housed in a 48-VFQFN exposed-pad package (supplier device package 48-VQFN, 7x7 mm), the MSP430F5242IRGZR requires a surface-mount footprint with a thermal pad. The 37 I/O lines are distributed around the QFN perimeter, which simplifies routing for a two-layer board in many applications.
For BOM lines that require a second-source option, the MSP430F5xx family includes pin-compatible density variants with the same footprint — a procurement buyer can qualify an alternative within the same series without a board spin.
