The EBI/EMI bus lets you attach external memory or FPGA-style peripherals without a glue-logic CPLD. On the analog side, a 16-channel 10-bit ADC handles sensor inputs. The LM3S9B90-IBZ80-C3T is officially classified as Obsolete per the manufacturer's lifecycle record. TI has not published a direct pin-compatible successor for this exact Stellaris part; the Stellaris family was folded into the Tiva C series, but those devices use different package footprints and peripheral maps. If you are still in design phase, a migration to a current TI Cortex-M4F part (such as the TM4C129x series) is worth evaluating, though it will require a board respin. Stencil aperture should match the ball diameter minus 10% for a clean solder joint.","metaTitle":"LM3S9B90-IBZ80-C3T Stellaris Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S9B90-IBZ80-C3T 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":"Tape & Reel (TR)","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, 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 16x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S9B90","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/cee75a99b07073a78d34478947d5df9d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for LM3S9B90-IBZ80-C3T?","answer":"Texas Instruments has not published a direct pin-compatible replacement for this Stellaris part.
