Product details

What this MCU is and where it fits

The Texas Instruments LM3S1332-IBZ50-A2 is a 32-bit ARM Cortex-M3 microcontroller from the Stellaris family, clocked at 50 MHz. It carries 96 KB of Flash program memory and 16 KB of RAM, with 57 general-purpose I/O lines and a 3-channel 10-bit ADC.

50 MHz Cortex-M3 — what it means for your control loop

At 50 MHz, the Cortex-M3 executes single-cycle multiply and hardware divide. The 96 KB Flash and 16 KB RAM support UART, SPI, SSI, and IrDA protocol stacks.

Lifecycle and sourcing reality

Texas Instruments has designated the LM3S1332-IBZ50-A2 as NRND (Not Recommended for New Designs). This means the part is still available for existing production but is not being actively promoted for new projects.

Frequently asked questions

Is LM3S1332-IBZ50-A2 obsolete or NRND?

Yes, Texas Instruments lists this part as NRND (Not Recommended for New Designs). It is still available for existing production runs but is not intended for new projects.

What is the replacement for LM3S1332-IBZ50-A2?

No official replacement order code is listed in the available records. For a new design, consider a current-production Cortex-M3 or Cortex-M4 MCU from TI's Tiva C series or another vendor with similar Flash/RAM and peripheral count.

What are the specifications of LM3S1332-IBZ50-A2?

It is a 32-bit ARM Cortex-M3 MCU at 50 MHz with 96 KB Flash, 16 KB RAM, 57 I/O, 3×10-bit ADC, operating from 2.25 V to 2.75 V over -40°C to 85°C in a 108-LFBGA package.

What is the operating temperature range of LM3S1332-IBZ50-A2?
