The 96 KB Flash holds a moderate code base — enough for a CAN gateway or sensor hub with a few protocol stacks, but not a full HMI with graphics. The 32 KB RAM supports a few kB of packet buffers and stack; watch the heap size if you are running multiple protocol layers. This part is marked obsolete by Texas Instruments. No official successor is listed in the Stellaris line.","metaTitle":"Texas Instruments LM3S2432-IQC50-A2 ARM Cortex-M3 MCU, 50 MHz","metaDescription":"TI Stellaris LM3S2432-IQC50-A2 ARM Cortex-M3 32-bit MCU at 50 MHz, 96 KB Flash, 32 KB RAM, CANbus/I²C/SPI/UART, 100-LQFP, -40 to 85°C.
