The 25 MHz core drives the PWM and Ethernet interrupt service routine. The 46 GPIOs and internal oscillator simplify board layout.
No last-time-buy window remains; the only supply channel is the independent surplus and broker market.
The -40 to 105 °C operating temperature range qualifies this MCU for industrial environments — motor drives in unventilated cabinets, outdoor telecom enclosures, and engine-bay-adjacent controllers.
Yes, the LM3S6610-EQC25-A2 is officially obsolete per Texas Instruments. No factory production or last-time-buy is available.
Texas Instruments has not published an official replacement order code for the LM3S6610-EQC25-A2. The part is sourced through independent surplus channels; any alternative would require application-level evaluation.
The LM3S6610-EQC25-A2 is a 32-bit ARM Cortex-M3 MCU with a 25 MHz core, 128 KB Flash, 32 KB RAM, 46 I/O, and integrated Ethernet MAC+PHY plus I²C, SPI, UART, IrDA, and QEI interfaces. It operates from 2.25 V to 2.75 V over -40 to 105 °C in a 100-LQFP package.
The LM3S6610-EQC25-A2 is no longer in production, but it can be sourced through independent surplus distribution. Availability is confirmed at RFQ time.
