Ethernet MCUs for deliver large memory densities and low-power processing efficiency

Freescale's Kinetis K64 120MHz IEEE 1588 Ethernet MCUs are now available from Farnell element14. They benefit from the 120MHZ ARM Cortex-M4F core and are ideal for applications with large memory densities and low-power processing efficiency, says the company. The microcontrollers support crystal-less USB design to save costs and board space, while sharing the functionality and scalability of the Kinetis portfolio. The ultra-low-power capabilities of the MCU include stop currents of <340nA, run currents of <250µA/MHz and a 4.5µs wake-up from Stop mode. the device features a GPIO with pin interrupt support HMI and a range of mixed-signal capabilities, including two fast 16-bit ADCs, two 12-bit DACs, three fast comparators and analogue voltage reference. The K64_120 also offers rich connectivity that includes Ethernet MAC, USB 2.0 On-The-Go, up to 6 UART, CAN, I2S, 3 DSPI and 3 I2C.
