Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM3S2678-IQC50-A2T | Higher clock speed (80 MHz), larger flash (256 KB), same peripheral set but adds Ethernet MAC - requires external PHY and more PCB area. | Targeted at networked industrial controllers needing TCP/IP stack and remote diagnostics - not suitable where CAN-only or cost-sensitive designs dominate. | Select when Ethernet connectivity and higher processing headroom are required; avoid if CAN-only fieldbus and minimal BOM cost are priorities. |

FAQ
What is the maximum operating frequency of the LM3S2110-IQC25-A2T?
The LM3S2110-IQC25-A2T operates at a maximum CPU frequency of 50 MHz, achieved using its internal PLL driven by an external 4–25 MHz crystal or oscillator. This frequency is specified across the full industrial temperature range (–40°C to +85°C) and 3.0–3.6 V supply, enabling deterministic real-time control with sub-microsecond interrupt latency. The LM3S2110-IQC25-A2T does not support overclocking beyond this rated speed.
Does the LM3S2110-IQC25-A2T include a hardware floating-point unit (FPU)?
No, the LM3S2110-IQC25-A2T implements the ARM Cortex-M3 core without a hardware FPU. It relies on integer arithmetic and software libraries for floating-point operations. For applications requiring native floating-point performance (e.g., advanced motor control or FFT), the pin-compatible TM4C123GH6PM - which integrates a Cortex-M4F core with single-precision FPU - is the recommended successor. The LM3S2110-IQC25-A2T remains optimal for fixed-point control algorithms.
How many CAN controllers are integrated into the LM3S2110-IQC25-A2T?
The LM3S2110-IQC25-A2T integrates two independent CAN 2.0B controllers, each supporting full CAN protocol compliance including identifier masking, message object arbitration, and error frame handling. These controllers share 32 message objects in RAM and support bit rates up to 1 Mbps. This dual-CAN capability enables robust communication in distributed industrial networks - a key differentiator of the LM3S2110-IQC25-A2T versus single-CAN microcontrollers in its class.
What package type and pin count does the LM3S2110-IQC25-A2T use?
The LM3S2110-IQC25-A2T is packaged in a 100-pin LQFP (Low-Profile Quad Flat Package) with 0.5 mm pitch and exposed thermal pad. It provides 70 general-purpose I/O pins, plus dedicated power, ground, clock, reset, and JTAG/debug pins. This package is RoHS-compliant and rated for industrial temperature operation (–40°C to +85°C), matching the mechanical and thermal requirements of dense industrial PCB layouts.
Is the LM3S2110-IQC25-A2T supported by current TI software tools and development environments?
Yes, the LM3S2110-IQC25-A2T is fully supported by TI's legacy StellarisWare Peripheral Driver Library and Code Composer Studio v5.x and earlier. While TI has shifted focus to the TM4C series, all official StellarisWare drivers, example projects, and CMSIS-compliant startup code remain publicly available and functional for the LM3S2110-IQC25-A2T. Development kits such as the EK-LM3S2110 evaluation board continue to operate reliably with modern toolchains via maintained JTAG/SWD debug interfaces.
