80 MHz Cortex-M3 with Ethernet, CAN, and USB OTG
The 65 GPIOs are mapped across a 108-ball BGA (10x10 mm), which keeps the board area tight but demands a 4-layer PCB for fanout. The connectivity set is what sets this part apart from a generic Cortex-M3: Ethernet MAC+PHY, two CAN 2.0B controllers, USB OTG (Host/Device), plus multiple UART, SPI, I²C, and SSI serial interfaces.
Industrial temperature and on-chip peripherals
The core runs from a 1.235 V to 1.365 V supply; the I/O bank is 3.3 V tolerant. On-chip peripherals include a 16-channel 10-bit ADC, PWM timers, a watchdog timer, brown-out detect, power-on reset, DMA, and an I²S audio interface — covering motor-control feedback, sensor acquisition, and human-machine interface audio.
The 108-ball BGA (10x10 mm, 0.8 mm pitch) is a fine-pitch package that requires micro-via or via-in-pad for full breakout of the 65 I/O and the Ethernet/USB differential pairs. Surface-mount only; no socket option exists for this BGA.
