Program memory is 64 KB of Flash (64K x 8), which fits a moderate firmware image with a bootloader and one or two application layers; the 8K x 8 SRAM provides workspace for stack and small data buffers. ## Peripherals and connectivity — what is on the bus The 32 general-purpose I/O lines are multiplexed with these peripherals; check the alternate-function map in the datasheet before committing the pinout. The 4-channel 10-bit ADC samples at a rate adequate for current-sense or temperature monitoring, but not for high-speed audio or vibration analysis. No stock or lead-time figures are published here, but the RFQ process returns a firm commitment.","metaTitle":"LM3S811-EGZ50-C2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S811-EGZ50-C2 32-bit ARM Cortex-M3 MCU from Stellaris series. 50 MHz core, 64 KB Flash, 8K x 8 RAM, -40°C to 105°C.
