The LM3S9790-IQC80-C3T: 32-bit ARM Cortex-M3 MCU from the Stellaris 9000 series, clocked at 80 MHz. It has 128 KB Flash and 64 KB RAM.
Within the Stellaris 9000 series, the LM3S9790 shares the 100-LQFP footprint and pinout with other members that differ in Flash/RAM density and Ethernet availability.
The ARM Cortex-M3 core runs at 80 MHz, with 128 KB of Flash program memory and 64 KB of SRAM.
It integrates Ethernet MAC+PHY, CAN 2.0B, USB OTG, plus UART, SPI, I²C, SSI, Microwire, IrDA, and LIN — making it a full networked-control MCU without external transceivers for most protocols.
