Product details

50 MHz ARM Cortex-M3 with industrial connectivity

The LM3S5762-IQR50-A0 from the Stellaris ARM Cortex-M3S 5000 series is a 32-bit single-core MCU clocked at 50 MHz, built around the ARM Cortex-M3 core.

On the interface side, the MCU integrates CANbus, USB OTG, IrDA, SPI, SSI, UART/USART, and Microwire — a mix that supports dual-role USB (host or device) and CAN-based industrial networks without external transceivers on the digital side. The 33 general-purpose I/O lines and internal oscillator reduce external BOM count. The 4-channel 10-bit ADC is adequate for slow analog sensing (temperature, voltage monitoring) but not high-speed data acquisition.

NRND — what it means for sourcing

No official successor part is listed in the available documentation. New projects should select a current-production Stellaris or Tiva-C family member with equivalent Flash/RAM and peripheral mapping.

Housed in a 64-LQFP package (10x10 mm body), surface-mount only.

Frequently asked questions

Is LM3S5762-IQR50-A0 obsolete or NRND?

The LM3S5762-IQR50-A0 is NRND (Not Recommended for New Designs) according to the manufacturer's lifecycle status. It is not fully discontinued, but TI advises against using it in new product designs. Existing designs can continue sourcing through independent channels while supply lasts.

What is the recommended replacement for LM3S5762-IQR50-A0?

No official replacement order code is listed in the available documentation. For new designs, consider a current-production Stellaris or Tiva-C series MCU from Texas Instruments with similar Flash density, RAM, and CAN/USB OTG capability. Pin compatibility should be verified against the target package.

What are the key specs of LM3S5762-IQR50-A0?

The LM3S5762-IQR50-A0 is a 32-bit ARM Cortex-M3 MCU running at 50 MHz, with 128 KB Flash, 64K x 8 RAM, 33 I/O, USB OTG, CAN, SPI, UART, and a 4-channel 10-bit ADC. Operating temperature is -40°C to 85°C, supply voltage 2.25 V to 2.75 V, in a 64-LQFP package.
