The 16-channel 10-bit ADC provides enough analog front-end for current sensing or temperature monitoring in a three-phase motor drive. ## 108-BGA footprint and layout considerations The core supply is a narrow 1.235 V to 1.365 V rail, which typically comes from an external LDO or switching regulator. Decoupling should follow the reference design: a 10 µF ceramic bulk cap plus 100 nF per supply pin pair, placed as close to the balls as the layout allows. The industrial temperature range means the board must handle -40°C startup without crystal oscillator reliability issues. ## Obsolete — sourcing for sustainment programs No direct pin-compatible replacement has been announced within the Stellaris family; the Stellaris line was transitioned to the Tiva C Series, which uses different package and peripheral mappings. Buyers should confirm date code availability and consider last-time-buy quantities for long-term sustainment.","metaTitle":"LM3S9792-IBZ80-C5 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S9792-IBZ80-C5 is an obsolete Stellaris ARM Cortex-M3 MCU from TI with 80 MHz core, 128 KB Flash, 64 KB SRAM, Ethernet, CAN, USB OTG.","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 9000","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, Ethernet, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"65","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":"LM3S9792","Program Memory Size":"128KB (128K 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/181cc36412055e9656da7ebc14aedf1d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for LM3S9792-IBZ80-C5?","answer":"Texas Instruments has not published a direct pin-compatible replacement for the LM3S9792-IBZ80-C5. The Stellaris family was superseded by the Tiva C Series (TM4C123/129), but those devices use different package footprints and peripheral maps. A form-fit-function replacement would require a board redesign.
