The LM3S2533-IQC50-A2T: 48 general-purpose I/O pins are available, along with a 3-channel 10-bit A/D converter for analog sensor inputs. Serial connectivity includes CANbus, I²C, IrDA, Microwire, SPI, SSI, and UART/USART — covering the common fieldbus and debug interfaces for industrial and automotive control modules. On-chip peripherals include brown-out detect/reset, power-on reset, PWM outputs, and a watchdog timer, reducing the need for external supervisory ICs.
Lifecycle and sourcing posture
For new designs, a parametric review of the broader Stellaris or TM4C Cortex-M4 family is advised.
