Any replacement candidate must match or exceed this clock rate to maintain timing closure on existing firmware and communications stacks. The Cortex-M3 architecture at this speed handles protocol stacks for Ethernet, USB, and CAN simultaneously with moderate headroom — a slower part will stall on the network buffers. ## Memory map: 512 KB Flash, 64 KB RAM 512 KB of Flash and 64 KB of RAM define the firmware and data space. A replacement needs at least this memory footprint unless the application code is recompiled for a different memory map. The 64K x 8 RAM organization is byte-addressable, standard for Cortex-M3. The LM3S9C97 integrates Ethernet (MAC+PHY), USB OTG, CAN, and multiple serial buses (I²C, SPI, SSI, UART, IrDA, Microwire, LIN). It also includes a quadrature encoder interface (QEI), PWM, DMA, and a 16-channel 12-bit ADC. The 108-ball BGA (10x10 mm body) is a surface-mount package that requires reflow soldering and X-ray inspection for void detection.","metaTitle":"Texas Instruments LM3S9C97-IBZ80-A1 Stellaris ARM Cortex-M3 MCU, 80 MHz","metaDescription":"LM3S9C97-IBZ80-A1 is an obsolete Stellaris ARM Cortex-M3 MCU. 80 MHz, 512 KB Flash, 64 KB RAM, Ethernet, USB OTG, CAN, in 108-BGA.
