Freescale Semiconductor (NYSE: FSL) will soon begin shipping Kinetis M series microcontrollers (MCUs) in volume quantities. Based on the 32-bit ARM® CortexTM-M0+ core, Kinetis M series products are designed for next-generation smart meter applications.
The cost-effective Kinetis M series MCUs combine a sophisticated analog front end (AFE), hardware tamper detection and low-power operation to enable the design of secure, high-accuracy 1-, 2- and 3-phase electricity metering solutions. Freescale also provides proven 1-, 2-, and 3-phase hardware reference designs with complex metrology firmware satisfying 0.1% measurement accuracy and all ESD requirements.
