TWR-K21D50M

The TWR-K21D50M is a Kinetis K21 50MHz MCU tower system module built on ARM Cortex-M4 core. Optimized for cost sensitive applications requiring tamper detection and security encryption and benefit from low power processing efficiency. This tower module is designed to enable rapid prototyping and development for applications requiring medium embedded memory densities, security through tamper detect and crypto unit and communication through USB. The TWR-K21D50M module operates as a standalone debug tool and can also be combined and used as part of the modular tower system development platform.
