It packs 96 KB of Flash and 16 KB of RAM, with 57 general-purpose I/O lines. 96 KB of Flash holds a moderate control stack: bootloader, RTOS kernel, driver layer, and a few application tasks. 16 KB of RAM limits runtime data buffers — enough for a few hundred bytes of Modbus holding registers or a small circular log, but not for a large display frame buffer or extensive data logging. Plan your stack and heap usage early in the firmware design. ## Industrial temperature grade — deployment environment Rated from -40 to 105°C, this MCU is qualified for outdoor telecom cabinets, factory automation panels, and engine-bay electronics. The 100-LQFP package (14x14 mm) reflows well under a hot-air station.","metaTitle":"LM3S1332-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz, 96KB Flash, 100-LQFP","metaDescription":"Obsolete LM3S1332-EQC50-A2 Stellaris ARM Cortex-M3 MCU, 50MHz, 96KB Flash, 16KB RAM, 57 I/O, -40 to 105°C.
