Product details

For a production design that needs a 16-bit ultra-low-power MCU in a tiny footprint, this part is a stable BOM line that will not force a respin in the next several years.

Peripheral set and memory sizing for control firmware

The 128 KB Flash (128K x 8) and 8 KB RAM (8K x 8) are sized for sensor-fusion algorithms, protocol stacks (e.g., Modbus RTU over UART, I²C sensor polling), and non-volatile data logging with wear leveling. The brown-out detect and POR circuitry ensures safe startup and shutdown in single-supply systems where the rail may ramp slowly. DMA offloads peripheral-to-memory transfers without waking the core, preserving the low-power advantage that defines the MSP430 architecture.

DSBGA assembly considerations

The package is surface-mount only; no socket exists for this form factor.

Frequently asked questions

Does MSP430F5219IYFFT have UART?

Yes, the connectivity set includes UART/USART, I²C, SPI, IrDA, and SCI interfaces.

What is the closest pin-compatible alternative to MSP430F5219IYFFT in this family?

Within the MSP430F5xx series, density variants (e.g., MSP430F5218 with 96 KB Flash or MSP430F5229 with 128 KB Flash and additional I/O) share the same DSBGA footprint and peripheral map. Pin compatibility across the series is maintained for the same package option, so a firmware-upgrade path exists without a PCB respin.
