The NXP MK64FN1M0VDC12 is a Kinetis K60-series ARM Cortex-M4 MCU running at 120 MHz, with 1 MB Flash and 256 KB RAM. It carries an Ethernet MAC, USB OTG, and CANbus.
120 MHz core on a Cortex-M4 handles a 16 kHz current loop with margin and still has headroom for the Ethernet stack.
Memory and connectivity — sizing the BOM line
1 MB Flash holds a full FreeRTOS image plus a TCP/IP stack and application code; 256 KB RAM gives enough buffer for two Ethernet frames and a CAN message queue. The 37-channel 16-bit ADC and dual 12-bit DAC cover analog front-end needs without an external converter. If your design requires more RAM for frame buffering or data logging, the MK64FN1M0VDC12 has an EBI/EMI interface to attach external SRAM or NOR Flash.
