16 MHz MSP430 core with 60 KB Flash — what the memory and speed mean for the BOM
Designs that need larger runtime data structures should budget for external SRAM or step up to a higher-RAM MSP430 variant.
The 105°C ceiling also suits under-hood automotive body electronics, though this part lacks formal AEC-Q100 qualification.
Peripheral set and I/O — what connects without external glue
The 8-channel 12-bit ADC handles analog inputs like thermistors, potentiometers, or current-sense resistors. The LINbus support is notable for automotive body-node designs — window lifts, mirror controls, or seat-position modules — where a single LIN transceiver connects the MCU to the vehicle bus.
Package and PCB integration — 64-VFQFN with exposed pad
The 64-VFQFN package (9x9 mm body) with exposed thermal pad requires a via-stitched ground plane under the pad for both thermal dissipation and electrical grounding. The pad is the main heat path — without proper soldering and thermal vias, junction temperature rises quickly above 400 mA continuous I/O load. The 48 I/O pins on a 64-pin package means several pins are no-connects or dedicated to supply/ground, which simplifies routing but wastes board area if every pin is needed. The package is surface-mount only; no through-hole alternative exists for this order code.
The ROHS3 exemption level covers current EU requirements, so no restriction for global shipping or medical/consumer compliance.
