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

24-03-2015 | Farnell element14 | Semiconductors

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.
