The 108-LFBGA package (10x10 mm body) brings out 60 general-purpose I/O pins, so this part suits designs that need a compact BGA footprint and a decent number of digital interfaces on a single chip. That is a broad mix: LINbus points to automotive body-electronics heritage, while SPI and I²C cover sensor and memory expansion. The 16-channel 12-bit ADC handles analog inputs like potentiometers, current shunts, or temperature sensors without an external converter. It belongs in factory automation panels, outdoor telecom gear, engine-bay controllers, or HVAC systems — anywhere the board sees freeze-thaw cycles or summer heat inside a sealed enclosure. The core runs from a 1.235 V to 1.365 V supply rail, so the board needs a clean low-voltage rail, likely from a 3.3 V LDO or a switching regulator stepping down to that sub-1.4 V range. No factory lead time, no last-time-buy window — the available inventory is what exists in distributor and broker stock worldwide. Any new design should treat this part as unavailable for volume production and look at current Stellaris or Tiva-C family alternatives.","metaTitle":"LM3S1G58-IBZ80-A1 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"Texas Instruments LM3S1G58-IBZ80-A1, Stellaris ARM Cortex-M3S 1000 series 32-bit MCU. 80 MHz core, 384 KB Flash, 64 KB SRAM, 60 I/O, 108-LFBGA.","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":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"60","Core Processor":"ARM® Cortex®-M3","Package / Case":"108-LFBGA","Product Status":"Obsolete","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S1G58","Program Memory Size":"384KB (384K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"108-BGA (10x10)","Voltage - Supply (Vcc/Vdd)":"1.235V ~ 1.365V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d3b5f7e0b53791b31a416526ae176f68.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LM3S1G58-IBZ80-A1 obsolete?","answer":"Yes, the LM3S1G58-IBZ80-A1 is listed as obsolete.
