It carries 64 KB of Flash and 8 KB of RAM, with 28 I/O lines and an 8-channel 10-bit ADC. The core runs at 50 MHz. This speed handles a single control loop or a Modbus RTU master without bit-banging. ## Memory sizing for firmware and data 64 KB Flash and 8 KB RAM place this MCU in the small-to-medium application tier. The Flash can hold a modest bootloader plus application code for a sensor hub or a simple HMI. The 8 KB RAM limits buffering — a full Ethernet stack or large data-logging buffer will not fit. ## Industrial temperature and on-chip peripherals The 8-channel 10-bit ADC reads potentiometers or thermistors with external scaling resistors.","metaTitle":"LM3S808-IGZ50-C2T Stellaris ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash","metaDescription":"LM3S808-IGZ50-C2T 32-bit ARM Cortex-M3 MCU, 50 MHz, 64 KB Flash, 8 KB RAM, 28 I/O, 8x10b ADC, -40°C to 85°C, 48-VQFN.
