The integrated 16-channel 10-bit ADC and internal oscillator reduce external component count. ## 64 KB Flash and 24K x 8 RAM — firmware and data headroom The 64 KB Flash (64K x 8) is the program store; a firmware image that fits within this boundary can be field-upgraded via the internal bootloader or SWD. The 24K x 8 SRAM provides working space for stack, heap, and DMA buffers. For a control application with moderate data logging or communication buffering, this RAM allocation is adequate — but a design that needs large look-up tables or multiple frame buffers should verify headroom early. The Flash endurance is typical for this class (100k cycles per sector), so wear-leveling in the filesystem layer is advisable if the config block is rewritten frequently. ## 108-BGA (10x10 mm) — layout and rework considerations The 108-ball LFBGA package with a 10x10 mm body uses a fine-pitch array that requires X-ray inspection after reflow to verify solder-joint integrity. The BGA footprint is not hand-solderable; a hot-air rework station with a preheat plate and a stencil for the bottom-side balls is the minimum tooling. The 67 I/O lines fan out to the BGA balls — the PCB escape pattern will need at least two signal layers for full breakout. Each unit should be physically authenticated — the laser-etched marking on the top of the BGA package must match TI's known font and plant code for the date-code week. Counterfeit risk is elevated for obsolete parts in BGA form; a decap and X-ray inspection is recommended before a production run.","metaTitle":"LM3S1P51-IBZ80-C3T Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S1P51-IBZ80-C3T is a 32-bit ARM Cortex-M3 MCU from the Stellaris series, 80 MHz core, 64 KB Flash, 24K x 8 RAM, industrial temp -40°C to 85°C, 108-BGA","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"80MHz","Series":"Stellaris® ARM® Cortex®-M3S 1000","Package":"Tape & Reel (TR)","RAM Size":"24K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"I²C, IrDA, Microwire, QEI, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"67","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Obsolete","Data Converters":"A/D 16x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1P51","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"108-BGA (10x10)","Voltage - Supply (Vcc/Vdd)":"1.08V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4b537d7b08f213ef30fdcb0c13b6e56c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S1P51-IBZ80-C3T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S1P51-IBZ80-C3T obsolete?","answer":"Yes, the LM3S1P51-IBZ80-C3T is listed as Obsolete.
