80 MHz Cortex-M3 with 512 KB Flash — what it means for the BOM
The LM3S5C31-IBZ80-A2 is a Texas Instruments Stellaris ARM Cortex-M3 MCU running at 80 MHz with 512 KB of Flash and 64K x 8 of RAM. The 67 I/O lines and rich peripheral set — CAN, USB, I²C, SPI, UART, and an external bus interface — make this part a natural fit for a multi-protocol industrial controller or a human-machine interface front-end. The 12-bit ADC with 16 channels covers analog sensing for current, voltage, and temperature monitoring on a single chip.
