Frequently asked questions
What is the speed and memory complement of this MCU?
The LM3S9U96-IBZ80-A2T runs at 80MHz on an ARM Cortex-M3 core, with 384KB of Flash and 96KB of SRAM on-chip. The program memory type is Flash. Connectivity includes Ethernet, USB OTG, CAN, LIN, I²C, SPI, SSI, UART, IrDA, Microwire, and QEI — all integrated, no external network PHY required for basic Ethernet.
What package and I/O count does the IBZ80 variant use?
The IBZ80 suffix designates a 108-ball LFBGA package (10x10mm, 0.8mm pitch) on Tape & Reel. It provides 65 programmable I/O lines and a 16-channel 12-bit ADC. The BGA package is surface-mount only and is not field-reworkable under standard repair workflows.
