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.","metaTitle":"MSP430F5219IYFFT 16-bit MCU, 128KB Flash, 25MHz, DSBGA","metaDescription":"Texas Instruments MSP430F5219IYFFT 16-bit MCU with 128KB Flash, 8KB RAM, 25MHz core, 31 I/O, -40°C to 85°C.
