The 64 KB SRAM gives headroom for packet buffers and data logging. The integrated 10-bit ADC (3 channels) handles slow analog inputs like temperature or pressure sensors without an external converter. For applications needing more memory or higher ADC resolution, a move to a larger Stellaris sibling is worth evaluating.","metaTitle":"LM3S2533-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz","metaDescription":"LM3S2533-IQC50-A2 Stellaris ARM Cortex-M3 MCU, 50 MHz core, 96 KB Flash, 64 KB SRAM, 48 I/O, industrial temp, NRND status.","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":"Tray","RAM Size":"64K 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":"48","Core Processor":"ARM® Cortex®-M3","Package / Case":"100-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 3x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S2533","Program Memory Size":"96KB (96K 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":"$19.4016","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/38b03106a267df1019dd902dd40d5344.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S2533-IQC50-A2/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S2533-IQC50-A2 obsolete?","answer":"This means the manufacturer still supports existing production but advises against using it in new designs.
