The connectivity set includes Ethernet MAC+PHY, USB OTG, and CANbus alongside SPI, I²C, UART, and SSI — enough to serve as a single-chip gateway between an industrial CAN network and an Ethernet backbone. 65 general-purpose I/O pins are available in the 100-LQFP package; the 14x14 mm body keeps the board footprint manageable for a two-layer routing attempt, though the 0.5 mm pitch demands careful trace spacing. ## Memory sizing and peripheral headroom 256 KB of Flash and 96 KB of SRAM — the SRAM is generous for a Cortex-M3 of this generation, leaving room for multiple packet buffers in a TCP/IP stack or a small RTOS heap alongside application data. The Flash is sufficient for a bootloader plus one or two firmware images if OTA updates are planned. The 16-channel 10-bit ADC covers analog inputs without an external converter for most sensor-conditioning tasks. DMA and PWM peripherals offload the core for time-critical output generation.
