It carries an integrated Ethernet PHY and USB OTG controller alongside CAN, LIN, and a full suite of serial interfaces — SPI, SSI, I²C, UART, IrDA, Microwire — plus a QEI for motor encoder inputs. The 108-LFBGA (10x10mm) package brings 65 GPIOs and a 16-channel 10-bit ADC. ## 80 MHz Cortex-M3 — enough headroom for a protocol bridge The 80MHz core on this part handles a TCP/IP stack, CANopen, and a USB device/host stack simultaneously without hitting the ceiling — the Stellaris peripheral DMA offloads the data movement. The 96KB RAM is the working buffer for Ethernet frames and USB endpoints; the 256KB Flash holds the application plus the Stellaris Driver Library. If you are porting a legacy design that used the full 256KB, the Flash is the binding constraint — there is no larger-density sibling in the same BGA footprint. ## Obsolete — sourcing through the independent channel Texas Instruments marked the LM3S9B96-IBZ80-C1T obsolete. No last-time-buy window remains open through the factory channel. No official pin-compatible replacement was issued by TI for this specific BGA variant; the Stellaris line was superseded by the Tiva C Series, which uses a different peripheral map and requires a board respin.","metaTitle":"TI LM3S9B96-IBZ80-C1T Stellaris ARM Cortex-M3 MCU, 80MHz","metaDescription":"Texas Instruments LM3S9B96-IBZ80-C1T Stellaris ARM Cortex-M3 MCU, 80MHz, 256KB Flash, 96KB RAM, Ethernet PHY, USB OTG, CAN.
