Frequently asked questions
What is the closest pin-compatible alternative to the LM3S1133-IQC50-A2?
No official cross-reference or pin-compatible second source is cited in the available record for this order code. Sourcing should proceed through independent channels with full lot verification, or an engineering respin to a current-production 32-bit ARM Cortex-M3 MCU in the same memory tier should be evaluated.
What speed does the LM3S1133-IQC50-A2 run at?
The LM3S1133-IQC50-A2 is rated for 50MHz core clock, based on the ARM Cortex-M3 architecture with an internal oscillator.
What series does the LM3S1133-IQC50-A2 belong to?
The device is a member of the Stellaris ARM Cortex-M3S 1000 series from Texas Instruments.
What compliance documentation does Texas Instruments provide for this part?
RoHS, REACH, and other compliance documentation availability should be confirmed directly with TI or an authorized channel partner — no compliance codes are present in the available record for this order code.
