This part carries an obsolete lifecycle status.
The 33 I/Os in a 64-LQFP (10x10 mm) package leave room for a parallel LCD or memory bus alongside the serial interfaces.
No official replacement or successor order code is recorded for this part. A pin-compatible alternative within the Stellaris family may exist, but the record does not specify one — verify against your firmware and peripheral requirements before substituting.
Yes, it integrates an 8-channel 10-bit ADC, which covers multi-sensor analog inputs without an external converter.
