Product details
Overview
LM3S6610-IQC25-A2 from Texas Instruments is a 32-bit ARM Cortex-M3 microcontroller with 256 KB flash, 64 KB SRAM, integrated Ethernet MAC, dual UARTs, I²C, SSI, PWM, analog comparators, and hibernation module. It operates at up to 50 MHz and supports industrial motor control and networked embedded systems requiring deterministic real-time response and low-power sleep modes.
For engineers reviewing the LM3S6610-IQC25-A2 datasheet, LM3S6610-IQC25-A2 pinout, LM3S6610-IQC25-A2 application, or LM3S6610-IQC25-A2 equivalent, key selection criteria include Ethernet MAC integration, hibernation current (≤1.7 µA), 50 MHz CPU clock, dual UART support with IrDA/SIR, and QFP-100 package compatibility for space-constrained industrial controllers.
Technical Context
The LM3S6610-IQC25-A2 implements the ARMv7-M architecture with NVIC, SysTick, MPU, and debug interfaces (JTAG/SWD). Its system-level design integrates a dedicated hibernation module with RTC, battery-backed memory, and wake-up sources - enabling sub-2 µA retention in battery-powered applications.
Peripherals include a full Ethernet MAC (MII interface, no PHY), two UARTs supporting IrDA and SIR encoding, one I²C master/slave controller, two SSI modules, six PWM generator blocks, and two analog comparators with programmable reference. All are memory-mapped and accessible via APB bus with configurable interrupt priority.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM3S6965-IQC50-A2 | Same package and core, but 512 KB flash, 64 KB SRAM, adds USB OTG controller and CAN interface | Required when USB device/host or CAN bus connectivity is needed; higher flash supports larger protocol stacks | Select LM3S6965-IQC50-A2 if USB or CAN is mandatory; otherwise LM3S6610-IQC25-A2 offers optimal cost/performance for Ethernet-only designs |
| TM4C123GH6PM | Successor family: Cortex-M4F core, 80 MHz, 256 KB flash, 32 KB SRAM, integrated PHY option, enhanced PWM and analog features | Required for floating-point math, higher throughput, or integrated Ethernet PHY; not pin-compatible | Choose TM4C123GH6PM for new designs needing performance headroom or future-proofing; LM3S6610-IQC25-A2 remains valid for legacy or cost-sensitive Ethernet MCU deployments |
Compared with LM3S6965-IQC50-A2 and TM4C123GH6PM, the LM3S6610-IQC25-A2 provides the minimal feature set required for deterministic Ethernet-connected control - balancing flash size, hibernation efficiency, and peripheral count without over-provisioning USB or CAN where unused.

FAQ
What is the maximum operating frequency of the LM3S6610-IQC25-A2?
The LM3S6610-IQC25-A2 operates at a maximum CPU clock frequency of 50 MHz, supported by its on-chip flash memory's zero-wait-state access at that rate. This frequency is achieved using the internal PLL driven from the main oscillator or an external crystal, and it defines the upper bound for deterministic interrupt latency and peripheral timing resolution in real-time applications.
Does the LM3S6610-IQC25-A2 include an integrated Ethernet PHY?
No, the LM3S6610-IQC25-A2 contains only an IEEE 802.3-compliant Ethernet MAC with MII interface. An external PHY chip (e.g., DP83848 or LAN8720) must be used to complete the physical layer. The LM3S6610-IQC25-A2 provides all MII signals (TXD[3:0], RXD[3:0], TX_EN, CRS, COL, etc.) on dedicated pins PA0–PA7 and PB0–PB7.
What is the hibernation current specification for the LM3S6610-IQC25-A2?
The LM3S6610-IQC25-A2 achieves a typical hibernation current of 1.7 µA when the hibernation module is active with RTC running and battery-backed RAM retained. This value is measured under specified conditions (VDD = 3.3 V, TA = 25°C) and enables multi-year operation on small coin-cell batteries in remote monitoring applications.
How many UARTs does the LM3S6610-IQC25-A2 support, and what advanced features do they include?
The LM3S6610-IQC25-A2 supports two independent UARTs. Each includes hardware IrDA 1.4 pulse shaping and SIR (Serial Infrared) encoding, eliminating the need for external IR transceivers. UART0 also supports full modem control (RTS/CTS), while both support FIFOs, programmable baud rates, and multiple interrupt sources including receive timeout and framing error detection.
Is the LM3S6610-IQC25-A2 pin-compatible with other Stellaris LM3S devices?
No, the LM3S6610-IQC25-A2 is not universally pin-compatible across the LM3S family. While it shares the 100-pin LQFP package with several variants (e.g., LM3S6965-IQC50-A2), pin assignments for peripherals like Ethernet MII, UART, and SSI differ. Board layout must be verified against the specific LM3S6610-IQC25-A2 pinout table; direct replacement requires validation of signal mapping and power domain routing.
