Product details

Stellaris LM3S6610 — obsolete Cortex-M3 with Ethernet, still in demand for legacy BOMs

The LM3S6610-IQC25-A2T: The industrial temperature grade (-40 to 85 °C) suits factory-floor controllers, building-automation gateways, and IoT edge nodes that need a compact Ethernet MAC in a 100-pin LQFP package.

This part is listed as Obsolete. Original production from Texas Instruments / Luminary Micro has ended.

25 MHz Cortex-M3 with Ethernet — the fit for cost-sensitive connectivity

The Cortex-M3 core runs at 25 MHz and includes Ethernet MAC, I²C, SPI, SSI, UART, IrDA, Microwire, QEI, PWM, and a watchdog.

Package and industrial temperature range

Housed in a 100-LQFP (14x14 mm) with 46 available I/O. Internal oscillator is available, though an external crystal is recommended for Ethernet clock accuracy.

Frequently asked questions

Where can I buy LM3S6610-IQC25-A2T?

Submit an RFQ for current availability, pricing, and date-code options. No stock or lead-time numbers can be stated here — they are confirmed at quote time.

What are the alternatives to LM3S6610-IQC25-A2T?

Within the Stellaris family, parts like the LM3S6918 share the Cortex-M3 core and Ethernet but differ in Flash density, package, or temperature grade. No direct pin-compatible drop-in exists. For new designs, consider the TM4C129x (Tiva C series) or a third-party Cortex-M3/M4 with Ethernet MAC from NXP or STMicroelectronics — each requires a PCB layout change.
