The 108-ball BGA package (10x10 mm) keeps the board area compact, though the fine pitch demands careful PCB routing and a controlled-impedance stackup for the Ethernet PHY interface. For a production BOM that still calls out the LM3S9B96-IBZ80-C3, the only sourcing channel is the independent distribution market — broker or surplus stock. Any volume requirement should be quoted against an RFQ so current availability and pricing can be confirmed before committing the line. A redesign to a current-generation Cortex-M4 or M7 part with Ethernet and CAN is the typical long-term move, but that involves a board spin and firmware port. ## 80 MHz core and memory — the design-fit check The 80 MHz core clock is the maximum rated speed; the flash requires zero wait states up to around 40 MHz and one wait state above that, which a firmware engineer must account for in the clock-configuration routine. The 256 KB Flash is adequate for a TCP/IP stack plus a CANopen or Modbus application, but leaves little headroom for over-the-air update staging — plan the image size budget early. 96 KB of SRAM is generous for a Cortex-M3 of this vintage; it can hold two full Ethernet frames (about 3 KB each) plus a small RTOS heap without thrashing. ## Peripheral set and package constraints The connectivity list — Ethernet MAC+PHY, two CAN 2.0B controllers, USB OTG, plus multiple UARTs, SPI, and I²C — makes this part a single-chip gateway candidate. The 65 GPIOs are multiplexed with these peripherals, so a pin-mux review is mandatory before layout. The 108-BGA package has a 0.8 mm ball pitch; route the Ethernet differential pairs on the top layer with a solid ground plane underneath to keep the signal quality within the PHY's return-loss spec.","metaTitle":"LM3S9B96-IBZ80-C3 Stellaris Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S9B96-IBZ80-C3 is an obsolete Stellaris ARM Cortex-M3 MCU with 80 MHz core, 256 KB Flash, 96 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":"96K 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":"LM3S9B96","Program Memory Size":"256KB (256K 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/131f5df7c0fe54f5ab0e2a4d60200285.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy LM3S9B96-IBZ80-C3?","answer":"Submit an RFQ to confirm current availability and pricing; the order is quoted and placed against that quote — no stock or price is published for this code."},{"question":"Is LM3S9B96-IBZ80-C3 obsolete?","answer":"Yes, the official lifecycle status is obsolete.
