Obsolete — sourcing reality for this BGA MCU
Texas Instruments has marked the MSP430F5514IZQE as obsolete. That means no further factory orders are accepted; the only channel for this exact order code is the independent surplus and broker market.
Package and mounting — 80-VFBGA design-in note
The MSP430F5514IZQE comes in an 80-VFBGA package (TI's MICROSTAR JUNIOR, 5x5 mm ball array). It is a surface-mount only device; no socketed prototyping option exists without an adapter board. The 47 I/O lines fan out across the BGA footprint, so a four-layer PCB with a dedicated ground plane under the BGA is recommended to keep signal integrity clean on the USB differential pair and the high-speed SPI lines.
