The 80 MHz Cortex-M3 core delivers enough throughput for real-time control loops and protocol bridging without an external PHY for Ethernet. The 256 KB Flash is adequate for a moderate application stack (TCP/IP, CANopen, USB device class drivers); the 96K x 8 SRAM leaves headroom for packet buffers and data tables. If your design relies on the Ethernet MAC+PHY and USB OTG combination, there are few pin-compatible alternatives in this package — the BGA footprint and supply voltage (1.235 V to 1.365 V core) require a board respin to substitute.","metaTitle":"TI LM3S9B90-IBZ80-C1 Stellaris ARM Cortex-M3 MCU, 80 MHz, 256KB Flash","metaDescription":"LM3S9B90-IBZ80-C1 Stellaris ARM Cortex-M3S 9000 MCU. 80 MHz, 256KB Flash, 96K x 8 RAM, Ethernet, USB OTG, CAN.
