Frequently asked questions
What replaces the LM3S1W16-IQR50-C3T?
No official successor order code or second-source cross-reference is listed in the available record. For new production, a migration to a current TI ARM Cortex-M3 or M4 device — such as the Tiva C Series family or MSPM0 series — is the engineering path, with pin-compatibility and peripheral register map confirmed against the target device.
How do I source the LM3S1W16-IQR50-C3T for a legacy build or repair?
The part is sourced to order against an RFQ through independent distribution. Availability, current pricing, and lead time are confirmed at quote time — contact the sourcing desk with your required quantity and date code preference.
