Frequently asked questions
Is the LM3S811-IGZ50-C2 still available through authorized distribution?
The Obsolete (EOL/hot) status means authorized-distribution allocation is no longer assured. Confirm current availability and any remaining last-time-buy window directly with the supplier before sourcing through broker channels.
What does the 48-VFQFN exposed-pad package mean for rework and drop-in compatibility?
The 48-VFQFN with exposed thermal pad is a 7×7mm surface-mount package. Pin-compatible drop-in candidates in a different package (such as a 48-LQFP) will require PCB rework and a new footprint — verify package match before treating any alternate as a direct swap.
Does the internal 50MHz oscillator meet UART baud-rate tolerance for industrial fieldbus links?
The internal oscillator is acceptable for standard UART communication at typical baud rates. For tighter timing requirements in fieldbus protocols, an external crystal should be evaluated against the specific link's baud-rate tolerance specification.
