Freescale MK20DX256VYY10 Low-power mcus with usb on-the-go Datasheet

32-bit MCUs
Kinetis K20 Family
Low-power MCUs with USB On-The-Go
Target Applications
Overview
• Barcode scanners
The Kinetis MCU portfolio consists of multiple pin-, peripheral- and software-compatible MCU
families based on the ARM® Cortex™-M4 core. Families are built from innovative 90 nm thin-film
storage (TFS) flash technology with unique FlexMemory (EEPROM) capability, and offer industryleading low-power and mixed-signal analog integration.
• Portable media players
• Printers
• Programmable logic controllers
The K20 MCU family is pin, peripheral and software compatible the K10 MCU family and adds Fulland High-speed USB 2.0 On-The-Go with device charger detect capability. Devices start from 32 KB
of flash in 5 x 5 mm 32 QFN packages extending up to 1 MB in a 144 MAPBGA package with a
rich suite of analog, communication, timing and control peripherals. High memory density K20 family
devices include a single precision floating point unit and NAND flash controller.

reliability
• Prevents code runaway in fail-safe applications. Drives output pin to safe
state external components if watchdog event occurs
• Secure data transfer and storage. Faster than software implementations
and with minimal CPU loading. Supports a wide variety of algorithms: DES,
3DES, AES, MDS, SHA-1, SHA-256
• Secure key storage with internal/external tamper detect for unsecured flash,
temperature/clock/supply voltage variations and physical attack
• General-purpose timers with hardware dead-time insertion and quadrature
decoding for motor control
• Infrared waveform generation for remote control applications
• Time base generation for RTOS task scheduler or trigger source for ADC
conversion and programmable delay block
• Enables the connection of external memories and peripherals
(e.g., graphics displays)
• Connection to SD, SDIO, MMC or CE-ATA cards for in-application software
upgrades, file systems or adding Wi-Fi® or Bluetooth® support
