The Kinetis family of microcontrollers include system security and flash protection features that can be used to protect code and data from unauthorized access or modification. This application note discusses usage of the security and flash protection features available on the Kinetis family processors. The chip security and flash protection features controlled using the flash configuration field will be covered in this application note.

In embedded systems, resources are often limited and getting the best possible performance out of those resources can be critical. Although the idea of performance and low power might seem contradictory, the ability to perform a task quickly and then enter a low power mode can lead to an overall reduction in system power consumption. Therefore, almost any system can benefit from efforts to improve performance.

Freescale’s FXTH87xx consist of complex system-on-chip products that contain a pressure sensor, a Radio Frequency (RF) transmitter, a Low Frequency (LF) receiver, an 8-bit S08 microcontroller (MCU), and may contain one or two axis accelerometers, all in one package. As with most S08 solutions, users must program the MCU with their program, but Freescale already ships low-level drivers, as well as compensation routines, within each part. In order to exploit these routines, the developer must be familiar not only with the MCU architecture, but also with the in-flash firmware. The aim of this document is to fast-track the learning curve of the latter part for someone that is already cognizant of the former.
