The 32 KB SRAM leaves room for a couple of CAN message buffers and a small RTOS heap. ## NRND — plan the exit now ## CANbus and the industrial peripheral set The CANbus interface is the standout connectivity option here — it lets this MCU drop into a CAN-based sensor hub or actuator controller without an external transceiver (though you still need a CAN transceiver on the bus side).","metaTitle":"LM3S2432-IBZ50-A2T Stellaris ARM Cortex-M3 MCU, 50 MHz, NRND","metaDescription":"LM3S2432-IBZ50-A2T 32-bit ARM Cortex-M3 MCU, 50 MHz, 96 KB Flash, 32 KB SRAM, CANbus, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 2000","Package":"Tape & Reel (TR)","RAM Size":"32K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"34","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Not For New Designs","Data Converters":"A/D 3x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2432","Program Memory Size":"96KB (96K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"108-BGA (10x10)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$16.4876","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/38b03106a267df1019dd902dd40d5344.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2432-IBZ50-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S2432-IBZ50-A2T obsolete?","answer":"TI is not actively promoting it for new projects, but it remains available through distribution for existing production.

Within the Stellaris family, the LM3S2xxx series includes higher-density variants with similar peripheral sets, but pin compatibility varies by package.
