The high speed bridge can transfer data up to 80MBps, while the low speed bridge can transfer data up to 25 MBps.

The ARM Cortex-M3 based LM3S9B96-IQC80-C1T has a total of 80K bytes of programmable flash memory for program storage, and 64K bytes of SRAM for data storage. It supports wide DC power inputs and serves several low, medium, and high voltage I/Os. It features extended peripheral features, including an Ethernet MAC, LCD controller, USB on-the-go (OTG) HS/FS interface, up to eight USARTs, I2C, SPI, SD, and CAN interfaces.

The extensible ARM Cortex-M3 based architecture of the LM3S9B96-IQC80-C1T makes it easier for developers to create device drivers for specific applications. It includes an ARM Cortex-M3 Core with memory protection unit (MPU) that allows developers to create secure, efficient applications. The ARM Cortex-M3 Core supports C and C++ based programming languages, making the development process faster and simpler.

The working principle of the LM3S9B96-IQC80-C1T is based on fetching program instructions from the program flash memory in order to execute commands. The processor then accesses the data that is stored in the SRAM and sends it to the I/O devices such as LCD screens, keyboards, motors and other peripherals. The processor fetches the data, processes it and sends it back to the I/O devices. When the data is sent to the central processing unit the processor makes decisions based on the program instructions.

The LM3S9B96-IQC80-C1T is ideal for embedded applications due to its low power consumption, support for multiple I/O devices, fast processing speed, and secure data storage. It can be used for creating a wide variety of applications such as automation systems, data acquisition systems, human machine interfaces, medical systems and automatic test equipment.
