Sourcing posture

The LM3S1620-IBZ25-A2T is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time. Given the NRND status, buyers should lock in quantities for near-term builds and plan for a design transition.

Frequently asked questions

Is LM3S1620-IBZ25-A2T obsolete?

The LM3S1620-IBZ25-A2T carries an NRND (Not Recommended for New Designs) status, meaning Texas Instruments no longer recommends it for new projects and will phase it out. It is not yet fully discontinued, but the end-of-life process has begun.

What is the replacement for LM3S1620-IBZ25-A2T?

No official direct replacement order code is listed in the available records. The closest functional alternatives are in the current Stellaris or Tiva-C ARM Cortex-M4 families, but those may differ in pinout, package, or supply voltage. A design review is required to confirm compatibility.

What is the operating temperature of LM3S1620-IBZ25-A2T?

The LM3S1620-IBZ25-A2T is rated for -40 to 85 °C, covering industrial and outdoor applications.

What are the key specifications of LM3S1620-IBZ25-A2T?

It is a 32-bit ARM Cortex-M3 MCU running at 25 MHz, with 128 KB Flash, 32 KB RAM, 52 I/O, and a 108-ball BGA package. Peripherals include I²C, SPI, UART, PWM, and a quadrature encoder interface.
