TWR-KM34Z50M: Kinetis M Series Tower System Module

The TWR-KM34Z50M is a development platform for the Kinetis KM3x and KM1x families of Kinetis MCUs. The TWR-KM34Z50M operates as a standalone debug tool and can also be combined and used as part of the modular Tower system development platform.

Kinetis KM1x and KM3x MCUs are based upon the low-power ARM® Cortex™-M0 core and are designed for single-chip one-two- and three -phase electricity meters, as well as flow meter and other precision measurement applications. Kinetis KM1x and KM3x MCUs include a powerful analog front end consisting of multiple 24-bit sigma delta ADCs, programmable gain amplifiers, voltage reference with low drift over temperature and a phase shift compensator. A large range of security features including a memory protection unit, external tamper detection pins, iRTC with tamper detect and a random number generator provide protection of supplier/user data within the MCU and from the MCU to the power grid.
