32-bit Kinetis MCUs represent the most scalable portfolio of ARM® Cortex™-M4 MCUs in the industry. Enabled by innovative 90nm Thin Film Storage (TFS) flash technology with unique FlexMemory (configurable embedded EEPROM), Kinetis features the latest low-power innovations and high performance, high precision mixed-signal capability.
For the Freescale Cup Challenge, we have provided several tutorials, example code and projects based on the twr-k40x256-kit. This board is part of the Freescale tower-system, a modular, reusable development platform that allows engineers to quickly prototype new designs.
The K40 chip is a 144 pin package with 512KB of Flash, 245Kb of Program Flash, 4KB of EEProm, and 64KB of SRAM.
