It has 57 I/O lines and peripherals including UART/USART, SPI, SSI, Microwire, IrDA, three 10-bit ADC channels, PWM, and a watchdog timer. At 50 MHz the Cortex-M3 handles a PID loop at a few kHz. The 16 KB SRAM is tight for heavy buffering. The LM3S1332-IQC50-A2 is marked obsolete by Texas Instruments.","metaTitle":"TI LM3S1332-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"Texas Instruments LM3S1332-IQC50-A2 32-bit ARM Cortex-M3 MCU, 50 MHz, 96 KB Flash, 16 KB SRAM, 57 I/O, 100-LQFP.
