The Kinetis K20 72 MHz microcontrollers (MCUs) are pin, peripheral and software compatible with the K10 MCU family featuring full speed USB 2.0 On-The-Go with device charge detect capability. Freescale's 32-bit Kinetis MCUs represent the most scalable portfolio of ARM® Cortex™-M4 MCUs in the industry. Kinetis K20 72 MHz devices start from 64 KB of flash in 10 x 10 mm 64 LQFP packages extending up to 256 KB in a 104 MAPBGA package with a rich suite of analog, communication, timing and control peripherals.


Features


Ultra-Low-Power
  • 10 low-power modes with power and clock gating for optimal peripheral activity and recovery times. Stop currents of <1.45 µA, run currents of <277 µA/MHz, 4 µs wake-up from Stop mode
  • Full memory and analog operation down to 1.71V for extended battery life
  • Low-leakage wake-up unit with up to eight internal modules and sixteen pins as wake-up sources in low-leakage stop (LLS)/very low-leakage stop (VLLS) modes
  • Low-power timer for continual system operation in reduced power state

Flash, SRAM and FlexMemory
  • 64-256 KB flash. Fast access, high reliability with 4-level security protection
  • 16-64 KB of SRAM
  • FlexMemory: 2KB of user-segmentable byte write/erase EEPROM for data tables/system data. EEPROM with over 10M cycles and flash with 70 µsec write time (brownouts without data loss or corruption). No user or system intervention to complete programming and erase functions and full operation down to 1.71V. In addition, 32KB FlexNVM for extra program code, data or EEPROM backup

Mixed-Signal capability
  • Up to two high-speed 16-bit ADCs with configurable resolution. Single or differential output mode operation for improved noise rejection. 500 ns conversion time achievable with programmable delay block triggering
  • One 12-bit DAC for analog waveform generation for audio applications
  • Three high-speed comparators providing fast and accurate motor over-current protection by driving PWMs to a safe state
  • Two programmable gain amplifiers with x64 gain for small amplitude signal conversion
  • Analog voltage reference provides an accurate reference to analog blocks, ADC and DAC, and replaces external voltage references to reduce system cost

Performance
  • ARM® Cortex™-M4 core + DSP
  • 72 MHz, single cycle MAC, single instruction multiple data (SIMD) extensions
  • 16-channel DMA for peripheral and memory servicing with reduced CPU loading and faster system throughput
  • Cross bar switch enables concurrent multi-master bus accesses, increasing bus bandwidth
  • Independent flash banks allow concurrent code execution and firmware updating with no performance degradation or complex coding routines

Timing and Control
  • FlexTimer with a total of 8 channels. Hardware dead-time insertion and quadrature decoding for motor control
  • Carrier modulator timer for infrared waveform generation in remote control applications
  • Four-channel 32-bit periodic interrupt timer provides time base for RTOS task scheduler or trigger source for ADC conversion and programmable delay block

Human-Machine Interface
  • Hardware touch-sensing interface with up to 16 inputs. Operates in all low power modes (minimum current adder when enabled). Hardware implementation avoids software polling method. High sensitivity level allows use of overlay surfaces upto 5 mm thick

Connectivity and Communications
  • USB 2.0 On-The-Go (full speed). Device charge detect optimizes charging current/time for portable USB devices enabling longer ba
