Product details

50 MHz ARM Cortex-M3 with integrated Ethernet and CAN

The LM3S8933-IQC50-A2: 32-bit ARM Cortex-M3 MCU from the TI Stellaris 8000 series, clocked at 50 MHz with 256 KB Flash and 64 KB RAM. It includes CAN, Ethernet, I²C, SPI, SSI, UART, and IrDA connectivity.

256 KB Flash and 64 KB RAM — firmware headroom for protocol stacks

The 256 KB Flash holds a TCP/IP stack plus application code; the 64 KB RAM leaves room for packet buffers and real-time data. The 50 MHz Cortex-M3 delivers deterministic interrupt response for the PWM and WDT peripherals — useful for motor-control loops that cannot tolerate jitter.

The 100-LQFP (14x14 mm) package keeps the board footprint compact.

End-of-life status — sourcing via independent channel

End-of-life. Sourcing runs through the surplus and broker channel.

Frequently asked questions

Where can I buy LM3S8933-IQC50-A2?
