This part is listed as obsolete. That means new designs should not start here — the only channel is surplus or broker inventory. If you have an existing BOM that calls out this MCU, you will need to qualify a replacement or secure a last-time-buy lot through independent distribution. The 0.5 mm pitch needs a decent solder-paste print, but it is a common footprint that most assembly houses handle routinely.","metaTitle":"Texas Instruments LM3S9C97-IQC80-A1 ARM Cortex-M3 MCU","metaDescription":"Texas Instruments LM3S9C97-IQC80-A1 Stellaris ARM Cortex-M3S MCU: 80 MHz, 512 KB Flash, 64 KB RAM, Ethernet/USB OTG/CAN, 100-LQFP, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Speed":"80MHz","title":"LM3S9C97-IQC80-A1","Series":"Stellaris® ARM® Cortex®-M3S 9000","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","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":"100-LQFP","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":"100-LQFP (14x14)","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/6f9fb609e5ac264e54d46c5d58f4d85c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LM3S9C97-IQC80-A1 obsolete?","answer":"Yes, the product status is Obsolete.
