Product details

25 MHz core and 96 KB Flash — sizing the firmware and throughput

The 25 MHz Cortex-M3 core handles control loops, protocol stacks (CAN, Modbus over UART), and sensor fusion without a heavy scheduler. The 32K x 8 SRAM supports a couple of CAN message buffers and a moderate call stack — watch the heap usage if you are running a TCP/IP stack over the SSI or UART.

For new designs, look at the current Stellaris or Tiva C Series parts from TI — they share the Cortex-M3 core and peripheral set but differ in package and memory options.

The 100-LQFP (14x14 mm) is a standard gull-wing package with 0.5 mm pitch — straightforward to hand-solder or reflow with a hot-air station. No exposed thermal pad, so the dissipation path is through the leads only; keep the ambient airflow reasonable if running the core and peripherals near the 85°C limit.

Frequently asked questions

Is LM3S2412-IQC25-A2 obsolete?

Yes, TI lists the LM3S2412-IQC25-A2 as obsolete. There is no official direct replacement from TI; for new designs consider current Stellaris or Tiva C Series Cortex-M3 parts. For existing BOMs, we source through independent distribution — submit an RFQ for current availability and pricing.

What is the replacement for LM3S2412?

No official pin-compatible replacement is listed by TI. The Stellaris and Tiva C Series families include Cortex-M3 MCUs with similar peripherals (CAN, I²C, SPI, UART) but different Flash/SRAM sizes and package options. Check the parametric search for a 100-LQFP part with 25 MHz or higher core speed and CAN interface.

Where to buy LM3S2412-IQC25-A2?

The LM3S2412-IQC25-A2 is obsolete, so standard distributor stock is depleted. We source it through our independent supply network — submit an RFQ and we will confirm availability and pricing at quote time.

LM3S2412 vs LM3S2110 what are the differences?

Both are Stellaris Cortex-M3 MCUs in 100-LQFP. The LM3S2412 runs at 25 MHz with 96 KB Flash and 32K x 8 SRAM, and includes CANbus. The LM3S2110 is a lower-end variant — check its datasheet for exact Flash/SRAM sizes and peripheral set; the key difference is typically the CAN interface and memory footprint.
