MSP430AFE252IPWR

MSP430AFE252IPWR is a TI MSP430 microcontroller from the ultra-low-power MSP430 family, aimed at sensor and analog-front-end (AFE) applications. It uses a 16‑bit RISC CPU, supports multiple low‑power modes with fast wake, and combines on‑chip flash (for code) and RAM (for data) with a range of peripherals.
Key points:
- On‑chip analog front‑end: suitable for sensor interfacing (e.g., ADCs, comparators, references are typical in AFE devices).
- Digital peripherals: timers, GPIO, and communication interfaces (I2C, SPI, UART via the eUSCI modules), plus interrupts.
- Package/variant: IPWR denotes a specific package and temperature/rating; check the TI product page for exact pin count and package details.
- Typical uses: battery-powered sensing, data logging, metering, portable instrumentation.
- Development: supported by Code Composer Studio and MSP430Ware; consult the datasheet/user guide for exact specs and electrical characteristics.
Note: For precise memory sizes, pin count, voltage ranges, and periphery details, refer to the MSP430AFE252 datasheet and TI’s product page.
