What are the key features of LM3S2B93-IQC80-C0?
- 32-bit ARM Cortex-M3 core clocked at up to 80 MHz for high-performance control
- Integrated 10/100 Ethernet MAC/PHY for direct network connectivity without external PHY
- USB OTG (On-The-Go) controller supporting both host and device roles
- CAN 2.0B controller for industrial field-bus communication
- Multiple 12-bit ADC channels, PWM generators, and UART/SPI/I2C peripherals
- QFP-package form factor with industrial-grade temperature operation
What is LM3S2B93-IQC80-C0 used for?
LM3S2B93-IQC80-C0 targets industrial networking gateways, building automation controllers, and factory-floor edge nodes that require simultaneous Ethernet, USB, and CAN connectivity from a single 32-bit MCU. Its 80 MHz Cortex-M3 core provides sufficient headroom for embedded TCP/IP stacks and real-time control loops. The device is also suited for energy management systems and smart grid metering where Ethernet-connected endpoints must also interface with local CAN or serial field buses.

Frequently Asked Questions
How does LM3S2B93-IQC80-C0's integrated Ethernet MAC/PHY reduce BOM complexity in networked industrial designs?
LM3S2B93-IQC80-C0 includes an on-chip 10/100 Ethernet MAC/PHY, eliminating the need for a separate external PHY IC and its associated magnetics-selection complexity. This saves board space and reduces BOM cost, while the 80 MHz ARM Cortex-M3 core has enough throughput to run a lightweight TCP/IP stack alongside real-time control tasks.
Can LM3S2B93-IQC80-C0 serve as both a USB host and a USB device in a single embedded design?
Yes. The integrated USB OTG controller supports both host and device modes, allowing the MCU to act as a USB device when connected to a PC for firmware updates or data logging, and to switch to host mode to communicate with USB peripherals such as storage drives or HID input devices. This dual-role capability is enabled without any external USB controller IC.
What clock speed does LM3S2B93-IQC80-C0 run at, and how does that compare to common 48 MHz Cortex-M0 alternatives?
LM3S2B93-IQC80-C0 operates at up to 80 MHz, providing roughly 67% more clock cycles per second than a typical 48 MHz Cortex-M0 device. When combined with the 32-bit Cortex-M3 pipeline and hardware divide instructions, this translates to substantially higher real-time performance for applications with simultaneous Ethernet, CAN, and ADC workloads.
What is the lifecycle risk for LM3S2B93-IQC80-C0, and should procurement teams plan for a replacement?
The YTEOL field for LM3S2B93-IQC80-C0 is marked EYTEOL, indicating that the end-of-life timeline has already been reached or is imminent. Procurement teams should treat this part as end-of-life and qualify a modern replacement such as a TM4C or STM32 Ethernet-capable MCU to avoid supply disruptions in production programs planning beyond 12 months.
