The 108-ball BGA and the specific peripheral mix (Ethernet + CAN + USB OTG) mean a drop-in replacement is unlikely; a redesign with a current-generation MCU is the long-term answer. ## 108-ball BGA — layout and assembly considerations The LM3S9C97-IBZ80-A1T comes in a 108-LFBGA package with a 10x10 mm body. The core supply is a narrow 1.235 V to 1.365 V rail. The 60 GPIOs are distributed across the ball map. ## Industrial temperature grade — deployment envelope The internal oscillator and POR/Brown-out detect help maintain reliable startup across the range.","metaTitle":"LM3S9C97-IBZ80-A1T Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S9C97-IBZ80-A1T is a 32-bit ARM Cortex-M3 MCU from the Stellaris 9000 series. 80 MHz core, 512 KB Flash, 64 KB RAM, 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":"Tape & Reel (TR)","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, Ethernet, I²C, IrDA, LINbus, Microwire, QEI, SPI, SSI, UART/USART, USB OTG","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":"LM3S9C97","Program Memory Size":"512KB (512K 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,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6f9fb609e5ac264e54d46c5d58f4d85c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S9C97-IBZ80-A1T/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM3S9C97-IBZ80-A1T?","answer":"There is no official pin-compatible replacement from TI.
