Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LM3S2678-IBZ25-A2T	Same core and package, but adds Ethernet MAC + PHY interface and doubles SRAM to 48 KB	Required where wired IP connectivity and larger data buffers are needed (e.g., Modbus TCP gateways)	Select LM3S2678-IBZ25-A2T only if Ethernet is mandatory; otherwise LM3S2110-IBZ25-A2T offers lower cost and power
Tiva C TM4C123GH6PM	Successor family with same Cortex-M4F core, higher clock (80 MHz), enhanced CAN FD support, and updated peripherals	Required for new designs needing CAN FD, floating-point math, or USB device/host capability	TM4C123GH6PM is not pin-compatible; redesign required-but offers longer product lifecycle and active support

Compared with LM3S2110-IBZ25-A2T, LM3S2678-IBZ25-A2T adds Ethernet at no pinout change, while TM4C123GH6PM delivers higher performance and modern features but requires board revision and software migration.

FAQ

What is the maximum operating frequency of the LM3S2110-IBZ25-A2T?

The LM3S2110-IBZ25-A2T operates at a maximum system clock frequency of 25 MHz, as specified in the TI SPMS038I datasheet. This speed is achieved using the internal precision oscillator or an external crystal source. The ARM Cortex-M3 core executes instructions at this rate with deterministic timing, making LM3S2110-IBZ25-A2T suitable for real-time control loops where cycle count predictability matters. Higher frequencies require migration to the Tiva C TM4C series.

Does the LM3S2110-IBZ25-A2T support CAN FD?

No, the LM3S2110-IBZ25-A2T supports only classical CAN 2.0A/B protocols (ISO 11898-1:2003) with fixed 11-bit or 29-bit identifiers and bit rates up to 1 Mbps. It does not implement CAN FD features such as flexible data-length or enhanced bit timing. For CAN FD, designers must select the Tiva C TM4C123GH6PM or later TI microcontrollers. LM3S2110-IBZ25-A2T remains appropriate for legacy CAN networks in industrial machinery and older automotive systems.

What debug interface does the LM3S2110-IBZ25-A2T use?

The LM3S2110-IBZ25-A2T uses a 4-pin JTAG interface (TCK, TMS, TDI, TDO) compliant with IEEE 1149.1, as documented in Section 4 of the SPMS038I datasheet. It supports boundary scan, flash programming, and real-time debugging via TI's ICDI or third-party JTAG adapters. SWD is not supported-this capability was introduced in the Tiva C series. Debug access to LM3S2110-IBZ25-A2T requires a JTAG header and compatible toolchain like Keil MDK or TI Code Composer Studio.

Is the LM3S2110-IBZ25-A2T still in production?

Texas Instruments discontinued the Stellaris LM3S series in 2017, and LM3S2110-IBZ25-A2T is now obsolete per TI's official product change notification (PCN). However, Aetrix Electronics maintains limited legacy inventory with full traceability and provides lifecycle coordination support for existing designs. New projects should evaluate the pin-compatible Tiva C TM4C123GH6PM as a functional upgrade path. LM3S2110-IBZ25-A2T remains viable for maintenance and replacement in deployed systems.

What are the thermal characteristics of the LM3S2110-IBZ25-A2T package?

The LM3S2110-IBZ25-A2T uses a 100-pin LQFP package (package code Z) with an exposed thermal pad. Its junction-to-ambient thermal resistance (θ_JA) is 32.5°C/W under JEDEC JESD51-7 conditions (2s2p layout), and junction-to-case (θ_JC) is 5.5°C/W. The device is rated for industrial temperature range (–40°C to +85°C). Proper PCB copper pour under the thermal pad is required to maintain reliability at full 25 MHz operation. LM3S2110-IBZ25-A2T thermal design must follow TI's AN-SPRAAR7 guidelines.
