At 16 MHz, the core handles periodic sensor reads and communication packet handling.
Rated for -40°C to 85°C ambient, the MSP430FR2532IRGER suits outdoor telecom enclosures, factory-floor sensor heads, and automotive cabin modules. The supply range of 1.8 V to 3.6 V lets it run from two alkaline cells or a single Li-ion battery without an external regulator, simplifying the power tree.
End-of-life (hot) status per TI.
The supply voltage range is 1.8 V to 3.6 V.
The part is listed as RoHS compliant per the supplier device package information.
The MSP430FR2433 offers 16 KB FRAM versus 8.5 KB on the MSP430FR2532IRGER, but both share the same 24-VQFN package and 16-bit MSP430 CPU16 core. The FR2433 includes additional peripherals such as a real-time clock and comparator; firmware migration is not pin-compatible without code changes.
The device is in a 24-VQFN (4x4 mm) package with 15 general-purpose I/O. The pinout is documented in the TI datasheet; no pinout detail is reproduced here.
