The 50 MHz clock is enough for most real-time control loops and protocol stacks (TCP/IP offload, CAN, Modbus) without needing a higher-speed part that would add cost and power. The 256 KB program memory and 64 KB data memory give the firmware team room for a RTOS, a communication stack, and moderate application code — if your BOM needs more than that, you are looking at a different density tier. ## Peripheral set and I/O — what connects without glue logic This means most common serial sensors, displays, and radios can connect directly — no external UART-to-SPI bridge or I²C expander needed. The 8-channel 10-bit ADC covers basic analog sensing (potentiometers, thermistors, current shunts) without an external ADC. If your design needs USB, CAN, or Ethernet, this part does not carry them on-chip — you would add an external transceiver or move to a Stellaris variant with those blocks. This means Texas Instruments will continue to manufacture and ship the part for existing production, but it is not intended for new design wins. For a BOM line already in production, NRND is a signal to evaluate the end-of-life timeline and plan a last-time buy or a migration to a successor. For new designs, the recommendation is to select an active part from the current Stellaris portfolio or an equivalent from NXP, ST, or Renesas. ## Supply rail and temperature — the operating envelope","metaTitle":"TI LM3SA000-IQC50-A2T ARM Cortex-M3 MCU, 50 MHz, NRND","metaDescription":"Texas Instruments Stellaris LM3SA000-IQC50-A2T 32-bit ARM Cortex-M3 MCU, 50 MHz, 256 KB Flash, 64 KB RAM, -40 to 85°C, 100-LQFP.","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 1000","Package":"Tape & Reel (TR)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, IrDA, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"52","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3SA000","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"2.25V ~ 2.75V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$23.6527","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/46084d62ef5295c959adf1f0b652baa1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3SA000-IQC50-A2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3SA000-IQC50-A2T compatible with standard ARM Cortex-M3 tools?","answer":"Yes.
