Kinetis
®
K8x MCU Family
Based on the ARM
®
Cortex
®
-M4 core, the K8x microcontroller (MCU) family offers
the security, scalability and flexibility to address the challenges of creating smart
devices for the Internet of Tomorrow.
The K8x MCU family extends the Kinetis portfolio
with advanced security capabilities including:
}
Boot ROM to support encrypted firmware updates
}
Automatic AES Decryption and execution from
external serial NOR flash memory
}
Hardware AES acceleration with side band attack protection
}
Support for public key cryptography
BENEFITS
}
CPU and system cache reduce latency of memory resources,
lowering power consumption and improving performance
}
Separate I/O power domain for up to 14 pins allow operations
without the need for external level translators
}
Flex
™
I/O peripheral expands MCU capabilities by emulating
serial, parallel, or custom interfaces using software drivers
provided by the Kinetis SDK
}
Low-power operation with state retention stop mode down to
5 µA with fast wake-up time and lowest power mode with only
330 nA
Kinetis K8x MCUs offer symmetric cryptographic acceleration
as a standard feature along with full-speed USB 2.0 On-The-Go
(OTG), including options for crystal-less device functionality. K8x
MCUs have 256 KB of embedded flash and 256 KB SRAM. In
addition the integrated QuadSPI interface supports connections
to non-volatile memory (serial NOR), allowing developers to
expand beyond the boundaries of a traditional MCU.
