It integrates 256 KB of Flash and 96 KB of SRAM. ## 80 MHz Cortex-M3 — what it means for protocol throughput At 80 MHz the Cortex-M3 core can sustain a full-duplex Ethernet MAC while servicing a CAN bus and a USB OTG bulk transfer. The 96 KB SRAM provides buffer space for Ethernet packets and a CAN message queue. ## Obsolete — last-time-buy already passed The LM3S9B95-IBZ80-C1 is officially obsolete. There is no active replacement listed by Texas Instruments within the Stellaris family; the entire Stellaris line has been superseded by the Tiva C series, which uses a different pinout and requires a board redesign. ## Connectivity and peripheral integration The part carries Ethernet MAC, two CAN controllers, USB OTG, and multiple UART/SPI/I²C serial ports. The 65 GPIOs are multiplexed with these peripherals.","metaTitle":"Texas Instruments LM3S9B95-IBZ80-C1 ARM Cortex-M3 MCU, 80 MHz","metaDescription":"TI Stellaris LM3S9B95-IBZ80-C1 ARM Cortex-M3 MCU, 80 MHz, 256 KB Flash, 96 KB SRAM, Ethernet MAC, CAN, USB OTG, 108-BGA, -40°C to 85°C.
