The 10 I/O are accessible on the QFN perimeter; the pad also serves as the primary ground connection. Surface-mount assembly is standard, but the QFN package means post-reflow inspection requires X-ray or side-view optics.
This is a standard catalog line from Texas Instruments, available through independent distribution. No last-time-buy risk or obsolescence pressure on this code.
Standard MSP430 toolchains apply: TI's Code Composer Studio (CCS) or IAR Embedded Workbench for MSP430. Programming and debug use the Spy-Bi-Wire (SBW) 2-wire JTAG interface, supported by the MSP-FET or eZ-FET debug probes.
