80 MHz Cortex-M3 with a full peripheral set
The LM3S5P31-IQC80-C3: It carries 64 KB of Flash and 24 KB of RAM — enough for a CAN gateway, a USB-to-serial bridge, or a motor-control node running a real-time stack. The peripheral list includes CAN, USB, UART, SPI, I2C, LIN, and a quadrature encoder interface, so it can sit in an industrial drive or an automotive body controller without glue logic.
Industrial temperature, single-core, 1.08 V to 1.32 V core supply
The core runs from a 1.08 V to 1.32 V supply, so the board needs a dedicated low-voltage rail.
TI lists this device as obsolete. That means the only channel is the surplus and broker market.
10-bit ADC and DMA for sensor fusion
Sixteen 10-bit ADC channels sample analog inputs from current sensors, thermistors, or potentiometers. The DMA engine moves data without CPU intervention, which matters when the 80 MHz core is busy with CAN message handling or USB packet processing.
