Product details

50 MHz Cortex-M3 with CAN and USB OTG

The LM3S5762-IQR50-A0T: The peripheral set includes CANbus, USB OTG, IrDA, Microwire, SPI, SSI, UART/USART, and four 10-bit ADC channels. The 33 general-purpose I/O lines and internal oscillator keep the BOM lean for industrial control, motor drive, or human-machine interface designs.

NRND — plan the last-time-buy now

That means the manufacturer will not support new design-ins, and a last-time-buy window may close without notice.

Industrial temperature and 64-LQFP footprint

The 64-LQFP package has a 10x10 mm body.

Frequently asked questions

Is LM3S5762-IQR50-A0T obsolete?

It is not yet fully discontinued, but the manufacturer will not support new design-ins. Existing production should plan a last-time-buy or qualify a replacement within the Stellaris family.
