Product details

What the 25 MHz core and 128 KB Flash mean for your BOM

The LM3S6610-IQC25-A2: The 25 MHz core and 128 KB Flash place it in the Stellaris 6000 family. The 32K x 8 SRAM supports a couple of socket buffers and a state machine.

Peripheral set — Ethernet, serial, and motion-control interfaces

The Ethernet MAC is the headliner — it allows a single-chip connection to an industrial network or a local control LAN without an external MAC/PHY chip. The QEI is a niche but valuable peripheral for motor-feedback or encoder-based position sensing in factory automation. The 46 general-purpose I/O pins are enough to interface a keypad, a small TFT display, and a few sensors alongside the serial buses.

The Stellaris family includes pin-compatible siblings with different Flash/RAM combinations for a density upgrade path.

Frequently asked questions

Is LM3S6610-IQC25-A2 equivalent to LM3S6610-IQC25?

The base product number LM3S6610 is shared; the suffix -A2 typically indicates a specific revision or packaging variant. The datasheet should be consulted to confirm any electrical or timing differences between the two suffix variants.
