What are the key features of LM3S2B93-IQC80-C0T?
- ARM Cortex-M3 core at up to 80 MHz with 256 KB flash and 96 KB SRAM for real-time embedded control
- Dual 10/100 Ethernet MAC controllers enabling redundant or dual-network industrial connectivity
- USB OTG and CAN 2.0 interfaces providing broad connectivity options in a single SoC
- Integrated 12-bit ADC with 16 channels and hardware PWM for motor-control and power-management applications
What is LM3S2B93-IQC80-C0T used for?
The LM3S2B93-IQC80-C0T is designed for industrial automation, factory networking, and building control systems requiring dual Ethernet connectivity alongside real-time CAN bus communication. Its 80 MHz Cortex-M3 core and 256 KB flash make it capable of running FreeRTOS-based network stacks and motor-control algorithms simultaneously. The device also suits energy metering and SCADA gateway applications where USB, Ethernet, and CAN must co-exist in a single node.

Frequently Asked Questions
What makes LM3S2B93-IQC80-C0T suitable for dual-network industrial gateway designs?
The LM3S2B93-IQC80-C0T integrates 2 independent 10/100 Ethernet MAC controllers, allowing it to bridge between two separate network segments without external switch ICs. Combined with the 80 MHz ARM Cortex-M3 core, 256 KB flash, and 96 KB SRAM, it can run a full TCP/IP stack on both interfaces while still handling CAN 2.0 traffic at 1 Mbps.
How does the ADC resolution and channel count of LM3S2B93-IQC80-C0T compare to 8-bit MCU alternatives for sensor acquisition?
The LM3S2B93-IQC80-C0T includes a 12-bit ADC with 16 input channels, providing 4096-level resolution versus the 256 levels of a typical 8-bit MCU ADC. This 16× improvement in resolution allows accurate measurement of small differential signals such as thermocouple outputs and current-sense voltages without external signal amplification in most industrial scenarios.
What is the operating temperature range of LM3S2B93-IQC80-C0T for use in harsh environments?
The LM3S2B93-IQC80-C0T is rated for an industrial operating temperature range of -40°C to +85°C, making it suitable for outdoor control panels, factory floors, and transportation equipment where ambient temperatures fluctuate widely. The 100-pin LQFP package also allows efficient heat spreading through the PCB copper pour under normal airflow conditions.
When should a designer consider LM3S2B93-IQC80-C0T instead of a modern Stellaris or Tiva successor MCU?
LM3S2B93-IQC80-C0T is best suited for legacy board revisions or long-lifecycle industrial products already designed around the LM3S platform, where firmware and pin compatibility outweigh access to newer peripherals. For new designs, TI's TM4C129x Tiva series offers 120 MHz Cortex-M4F, more flash, and active support, but LM3S2B93 remains available for production continuity with the same 80 MHz class performance.
