It carries 32 KB of Flash program memory and 8 KB of SRAM, with 30 general-purpose I/O lines and a 6-channel 10-bit ADC on-chip. ## On-chip peripherals and I/O Connectivity covers Microwire, QEI (quadrature encoder interface), SPI, SSI, and UART/USART. The 30 I/O lines in a 48-LQFP leave most pins available after routing the ADC and serial interfaces. The 6-channel 10-bit ADC samples at a rate suitable for current-sense or temperature monitoring, not precision instrumentation. ## Supply and temperature range","metaTitle":"LM3S618-IQN50-C2 Stellaris ARM Cortex-M3 MCU, 50 MHz, 32 KB Flash","metaDescription":"LM3S618-IQN50-C2 32-bit ARM Cortex-M3 MCU from the Stellaris 600 series. 50 MHz core, 32 KB Flash, 8 KB RAM, 30 I/O, industrial temp.
