1 Kinetis Portfolio
Kinetis is the most scalable portfolio of low power, mixed-
signal ARM
®
Cortex
™
-M4 MCUs in the industry. Phase 1 of
the portfolio consists of five MCU families with over 200 pin-,
peripheral- and software-compatible devices. Each family
offers excellent performance, memory and feature scalability
with common peripherals, memory maps, and packages
providing easy migration both within and between families.
Kinetis MCUs are built from Freescale’s innovative 90nm
Thin Film Storage (TFS) flash technology with unique
FlexMemory. Kinetis MCU families combine the latest low-
power innovations and high performance, high precision
mixed-signal capability with a broad range of connectivity,
human-machine interface, and safety & security peripherals.
Kinetis MCUs are supported by a market-leading enablement
bundle from Freescale and numerous ARM 3rd party
ecosystem partners.

Figure 1. Kinetis MCU portfolio
All Kinetis families include a powerful array of analog, communication and timing and control peripherals with the level of
feature integration increasing with flash memory size and the number of inputs/outputs. Features common to all Kinetis
families include:
• Core:
• ARM Cortex-M4 Core delivering 1.25 DMIPS/MHz with DSP instructions (floating-point unit available on
certain Kinetis families)
• Up to 32-channel DMA for peripheral and memory servicing with minimal CPU intervention
• Broad range of performance levels rated at maximum CPU frequencies of 50 MHz, 72 MHz, 100 MHz, 120
MHz, and 150 MHz
• Ultra-low power:
• 10 low power operating modes for optimizing peripheral activity and wake-up times for extended battery life.
• Low–leakage wake-up unit, low power timer, and low power RTC for additional low power flexibility
• Industry-leading fast wake-up times
• Memory:
• Scalable memory footprints from 32 KB flash / 8 KB RAM to 1 MB flash / 128 KB RAM. Independent flash
banks enable concurrent code execution and firmware updates
• Optional 16 KB cache memory for optimizing bus bandwidth and flash execution performance. Offered on K10,
K20, and K60 family devices with CPU performance of up to 150 MHz.
• FlexMemory with up to 512 KB FlexNVM and up to 16 KB FlexRAM. FlexNVM can be partitioned to support
additional program flash memory (ex. bootloader), data flash (ex. storage for large tables), or EEPROM backup.
FlexRAM supports EEPROM byte-write/byte-erase operations and dictates the maximum EEPROM size.
• EEPROM endurance capable of exceeding 10 million cycles
• EEPROM erase/write times an order of magnitude faster than traditional EEPROM
