The Texas Instruments LM3S1620-IBZ25-A2T is a 32-bit ARM Cortex-M3 MCU from the Stellaris series, clocked at 25 MHz with 128 KB of Flash and 32 KB of RAM.
Given the NRND status, buyers should lock in quantities for near-term builds and plan for a design transition.
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.
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.
The LM3S1620-IBZ25-A2T is rated for -40 to 85 °C, covering industrial and outdoor applications.
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.
