Product details

16 MHz core — what that means for timing

The 16 MHz clock is the maximum CPU speed. For sensor polling, control loops, or communication protocol handling, this sets the instruction throughput ceiling.

Memory sizing: 16 KB Flash, 512 bytes RAM

The 16 KB Flash is enough for modest firmware stacks — sensor fusion, simple control algorithms, or a communication protocol like Modbus RTU over UART. The 512-byte RAM is tight; you'll need to budget stack, global variables, and buffers carefully. Consider external EEPROM or a larger RAM part if your data set exceeds this.

The 32 general-purpose I/O pins give you room for parallel interfacing or keypad scanning.

Frequently asked questions

Is the MSP430F2254IRHAR RoHS compliant?

Yes, it is ROHS3 compliant.

What is the closest functional second-source for the MSP430F2254IRHAR?

The TI F280041PZQR is a different architecture (32-bit C28x) with higher speed (100 MHz), more memory, and automotive qualification, but it is not pin-compatible or a direct replacement. For a true MSP430 alternative, look at other MSP430F2xx or MSP430G2xx parts with similar Flash and RAM.
