Product details

50 MHz Cortex-M3 with Ethernet and CAN — what you get

The LM3S8530-EQC50-A2: The peripheral set includes CAN, Ethernet, I²C, SPI, SSI, UART, IrDA, and Microwire, plus a PWM unit, watchdog timer, and brown-out detect.

The LM3S8530-EQC50-A2 is officially obsolete per the manufacturer's lifecycle status. There is no official TI successor listed for this part, so a pin-compatible drop-in replacement is not guaranteed — any substitution requires a board-level qualification review.

Storage and handling for the reels

The 100-LQFP package is MSL 3 — moisture-sensitive. If the sealed dry-pack has been opened past the floor-life window, a bake before reflow is required. Store the reels in a dry cabinet or reseal with desiccant.

Frequently asked questions

Is LM3S8530-EQC50-A2 obsolete?

Yes, the LM3S8530-EQC50-A2 is officially obsolete. Texas Instruments no longer manufactures it.

What is the replacement for LM3S8530-EQC50-A2?

There is no official successor listed for the LM3S8530-EQC50-A2. Any replacement would require a board-level evaluation of a different Stellaris or Tiva C Series MCU, and is not a guaranteed pin-compatible drop-in.

What are the specifications of LM3S8530-EQC50-A2?

Key specs: 32-bit ARM Cortex-M3 core at 50 MHz, 96 KB Flash, 64 KB SRAM, 35 GPIOs, peripherals include CAN, Ethernet, I²C, SPI, SSI, UART, IrDA, Microwire, PWM, WDT, and brown-out detect.

Can I use LM3S8530-EQC50-A2 in a new design?

Using this part in a new design is not recommended because it is obsolete. Sourcing depends on surplus inventory, which carries supply risk. A current-production Stellaris or Tiva C Series MCU would be a more reliable choice for a new BOM.
